Great service on time no complaints here

Great item. I got 5g before but the research has been so good I’m getting 10 this time. The free samples are great quality.

A1 product and fast shipping.

A1 product and fast shipping.

Please add all my samples due to the incredibly long wait time on my last order. I freelance research and it nearly got me evicted, other than that you guys are MORE THAN AWESOME, reliable, and amazing

How buy it product?im russian!

Is this one coming back? Was about to purchase. When is restock?

Awesome product very legit!!! Very strong. (Not a scam)!!!!!!! Took a lil long for shipping but overall worth it!!

Really happy with this website and this analogue, keep up the good work, From Australia 😀

Got this as a sample and as always, am highly satisfied with RCBs quality and their support team is the best! I have and will continue to reccomend RCB to my many other researchers!

Some of the purest chems at the best price you can find, been going thru RCB For a while, also great customer service!!

So sad no more 2f from them it was awesome

14 days from shipping date to doorstep. Always reliable. Will be back

Great stuff. To bad it won’t be restocked due to Chinese ban of 2-FDCK

Third time ordering I have to say I am impressed with their customer service as always package took a long time to arrive due to being in the middle of the Covid crisis I waited almost two months before asking to re ship and they did so immediately and I had a tracking number immediately I was somewhat less enthused with quality this time around the flualp I expected to test well but it seems weaker than alp which by all research it should not over all I think them the only trustable clearnet site I would order from still and would give the potency a 4 of 5

This is the best etizolam powder I’ve ever purchased and will most definitely purchase more, I would have gave 5 stars but it took about 35 days to get delivered to me, but that’s okay I’m still happy that it made it here, thank you so much again and will be purchasing again very very soon

Research shows this chem to be an effective stim. Similar to hexen. But dare i say better?

Wonderful material, can’t wait for this to be restocked.

It seemed that my package wasn’t weighed up perfectly, a little disappointed as I need it for “Research” but all In all the Etizolam is really potent, be careful guys and get yourself Propylene Glycol, and Diamond scales that weigh to the .001 of a gram at the least, shipping took for ever but I’m have I received my packed, please restock in 2-FDCK soon as I need bulk. Thank you again RCB for a 2/2 success rate to Australia

Excellent, trustworthy, reliable and efficient business, RCB are truly the greatest. The eutylone appears and tests beautifully. Research yields very, very positive, promising and impressive results. 110% satisfied

First time ordering from this vendor. I was very nervous, but everything came through and even faster than expected, about 2 weeks. They put the free sample in with the order after I weighed it. Discrete packaging. It’s difficult to track packages out of country, and expect a time period of no updates before it gets to customs, but it IS coming. Every time I emailed with questions from the website I got a quick and polite response giving reassurance on the status of my order. The product was pure and well worth it. I’m so glad to have found a reliable vendor and will continue to use them in the future.

repeat customer – reliable shipping, quality product, good communication… thanks.

Very successful research and a great vendor with spectacular customer support! I would give it ten stars if I could.

Amazing stuff. Even more amazing, my order did not arrive, and they agreed to reship. And here it is, one month later. You guys are the best.

I had received 1gram as a sample. This was my first experiment with my compound but I’m an avid researcher since 2009. I would say it was worth the money. I’m expecting a larger sample to study.

The name might remind you of FUB-AMB, 5F-AMB, or even 5fMBMB2201. Well it’s not as strong as any of those. Even though it has a weaker profile the aroma reminded me of PB-22 and BB-22 ect.

I was skeptical this would compare to the flourinated analogues. But this was better than ADBB and considerably better than 5FEMB2201. But not stronger than 4FMDMB-bica. The 1 gram sample came exactly as depicted. The aroma is not as bad as the others. The residue is more powdery but not as foul as the current selection.

My newest package has arrived, order took only 2 weeks to the Midwest! I had never researched Eutylone until today and am already having major breakthrough! I’m VERY plesantly surprised! Purity is amazing. Prices are very competitive. Shipping time was outstanding. Staff at RCB really set them apart. They keep their word and always very supportive and helpful.

Among the purest Etizolam I have ever researched. I hadn’t had any Etiz in my lab since I moved on the studying Clonazolam and FluAlprazolam but the free Etiz sample I got with my last order made to decide to go back to Etizolam more often. RCB staff are always on point and are always very responsive and helpful.

Great product, even better company. Test results are always as expected, but sometimes we have to release the hypothesis before we conclude. They will go above and beyond to help, even during a health crisis I received my package no issue.

I have been actively involved in academic research In this field for over two decades… In that 20 years I have written exactly 1 review for a company… and that company is RCBest. It has manage to exceeded even my cynical expectations. ▪︎Quality/Purity of Compound: Check+ ▪︎Consistency: Check ▪︎Price competitive: Check ▪︎Secure/Safe Shipment: Check ▪︎Professionalism: Check+ *Samples: not only makes a customer feel more valued, but gives the buyer the unoque opportunity to expand their catalogue.

Purest powdered etizolam I’ve ever bought!

I received this as a free sample with an order of 5FMDMB2201, 5FEMB2201, & 5CL-ADB-A. While the aroma and potency of this one is a little more mild. It still holds up.

The product came exactely as depicted in the photo. Came in less than two weeks and is potentially more potent than 5FEMB2201. Not as potent as 5fMDMB2201 from what I remembered. But it’s hard to say because they no longer stock it. Although I would still urge caution when analyzing this in your lab.

I actually like this0 Benzodiazepine the most, it’s not too sedating, esp wit other cns depressent. Never had a blackout once. I eyeball this stuff, but I have consumed 200mg Midazolam the whole weekend, with some other stuf0f like several 200mg Morphin caps. 2fdck I got as a ample, which I dint expect much from at all was very nice!

Incredible purity, top notch customer service! I will not research products from anyone but RCB. My only regret is I did not discover them years ago!

RCB always comes through for me and it has benefitted my research greatly. Top quality product, excellent customer service, good delivery time considering everything that is going on. I have refered many of my fellow researchers and will continue to do so! Best Clonazolam I have ever studied!

Hoping for the best! Pharmacokinetics look promising!

Interesting. If this priduct is as it is predicted based on similar chemistry, we’re going to feature this on our site!

Product showed up FAST! Thank you RCBO! Haven’t brought to the lab yet but thank you

Research indicates high purity , coupled with psychedelics. Was most euphoric for the lab rats. Good honest business people.

I have to join the choir on this one. RCB has been able to deliver consistently when many others did not. Research with MEP on test animals showed extended duration and decreased side effects over most currently available products in this line.

I ordered in the middle of the pandemic and it still only took 20 days to get to me!!! I love this site, totally legit!

Came quickly considering COVID. Everything weighed exactly and great quality. Great first order and will be buying larger amounts in the near future. Thabk You BoneyTreez

Great quality, the free sample of Etizolam was great, caused my lab rats to black out for 2 days and dance beside the pool at the hostel during the day pumping music, they had a good time and more research is definitally to be conducted.

Surprising good results, order more straight after I awoke from a black out only to find I’d spilled my 2-FDCK and my rats drank all my Etizolam. Bought more straight away

very pure substance, good-value, shipped relatively fast and stealthy. Overall, 5/5

Just wanted to let you guys know the order arrived and it’s testing out great! I am glad you stocked the eutylone. I will likely be placing a larger order soon!

Took a month so get it but very satisfied with these chems. Great service, quick to respond and great company! Will order again soon!!

great vendor, top notch quality for research, never failed delivery! Long time customer

Excellent Product! Great delivery.

Excellent Product!

Extremely pure!

You’ve one of the greatest webpages.

Product is excellent. Very pure.

2 weeks and I got it. Very potent and good quality. Awesome stealth also.

Took about 2 weeks to arrive but the stealth was great. About the potency I would say this could be better, at least I thought this because this is from china 5/5 everything else but 4/5 for potency. Afterall, no complaints

Great product 👍 suggest it !!

Order #2 everything is exactly as expected! Thank you

Order number 2. Same professional service! Thank you again!

grade A. thank you for helping further scientific research.

Wonderful brilliant chemical. Expensive but great!

After almost a month and a half, it showed up. Surprised and amazed at the quality

Rcb has the highest purity product I have tested in my lab. Great product, great staff. Packaging was great as well. Speedy shipping even amongst a world pandemic crisis. These guys deserve a medal of Honor for: the time and energy they put into keeping the researchers informed. Loyal customer for life……

Only company to be ur supplier. Love them

It came today and everything looks good. Thanks again. I’ll definitely be back again soon. Thanks for Everything. Very good job I’d say. and this is a goood chemical for researching!

Hi friend, I did receive my package. Scientifically speaking, 5femb2201 was excellent

so profeshonal customer service i was looking for a good rc vendor it took me months to find one that was totally legit like rcb im happy i waited and found the best recived tracking within 24 hours i think that this will be worth the wait the best things alwaystake a lil time be pattient

i already know this sites legit it is my first time going through them personaly but i can tell by the customer service already and reviews its a good site im probly gonna get sample pack c next i havnt got the first one yet but they were so quick to respond and offer tracking im confiedent with these guys

First off, I need to say that this company has never let me down. Amazing stealth and customer service, extremely fast replies. The most professional service a company has ever provided, period. I am beyond blessed to have had the pleasure to do business with them. Research has always been consistent, and product quality has never let me down. I highly recommend giving them a chance. They certainly have the most fair prices I’ve come across. I truly love rcb. Any negative reviews are competitors trying to ruin their reputation. I have certainly never been let down by them and I will continue coming back.

Great product long time to ship but it came as promised and def purity is there. Great for research. Reputable company. I trust them and will be ordering again just waiting 9n response they will send you 20 percent off coupons and free samples if you leave a review on sights or blogs

Great deal! Shipping was amazing and stealth was 10/10.

top business in this industry!

Its is an often recited proverb, “If it sounds too good to be true, it probably is…” This is one fine counter example to such cliches. Based on the size of your purchase, you can included 1 – 3 FREE samples in your order. In my last order of 2-fdck I got samples of bmdp & ebk (1.5 grams each.) And I’m pleased to add that both free samples worked in the lab wonderfully proving efficiency and purity of both products. While both had similar stimulative/euphoric results during lab analysis, they were also quite distinct in characteristics of their individual profiles. Ultimately, both were regarded highly for quality and purity, leading to very successful initial tests in the lab. Hoping to see ebk restocked for purchasing. Meanwhile, bmdp provides our lab with new research opportunities we were previously unaware of. Finally, the shipping and service was fast (both in products received and in emails returned,) and after nearly 2 years of business with RCB, I am easily able to recommend them to any labs looking to do research with this class of novel compounds. Thanks RCB~

This product is in high demand everywhere. Waiting patiently for a big restock.

Very helpful customer service, pure product, and great stealth.

Does anyone know if this is coming back soon or knows about them all being out of stock??? Hopefully will be back to normal soon!

Very potent. Will make testt animals get lost in thought but still active to go through the day, of course with no recollection of what happened. Would be nice to mix with another benzo to even the heaviness and lethargy. Overall best product and company to deal with.

Have had shipping over a month but everything has always arrived eventually.

2nd MEP order after noticeable improvement in the problem solving and related activities in several types of mice. Order delayed 3 weeks this time as product ran out on the day ordered. Good communication with vendor – promised to add 20% when re-stocked. I reminded them when product came back online. It shipped the next day, tracking was in place by day 3, arrived in good shape (day 21), probably 2% added (didn’t check). Early results consistent with prior data, Thanks.

Great service and communication. Professional. Always comes on point. Tests always come out great :). Plan on another order soon. Thanks guys

Excellent product, delivered to east coast in 3 week. Customer service was there every step of the way. Thank you

RCBO are true professionals, thank you, Just BE PATIENT!

I was hesitant to place an order overseas but I took the plunge and I’m glad I id. Shipping was 3 weeks + 2-3 days to East coast and Value was unbeatable. Thank you RCB!

I was a little hesitant to order international but regardless, Product came professionally sealed in 3 weeks to East Coast. All I can say is THANK YOU!

I was hesitant at fist while waiting for tracking but it arrived VERY well packaged about 3 weeks from placing order to the East Coast. Product tested exactly as expected. Will be back to sample other product. Thank you!

Quality product and service as usual. Our notoriously difficult customs facility took no time at all, and the compound purity more than passes muster. They also correspond with you very politely and quickly, so overall I’m very satisfied and will be a return customer. Thanks!

Second time ordering from them and once again delivery was seamless (took about two weeks, no issue with customs despite going through a notoriously difficult ISC, great stealth to boot), and the product more than passes muster as high purity. I’ll always advocate for RCB! Thanks guys.

Came here after being referred by a friend. Ordered 2gs 2FDCK/100mg Clam. Spent one month sitting in the ROK (South Korea), and when it was finally shipped stateside it was IMMEDIATELY taken by customs. It’s been two months in total (one month in Customs NYC) they have been VERY nice and VERY responsive throughout the ordeal, and have (supposedly) Reshipped the order, except I was told I had to use a different name/address and telephone number (not sure why they need that). So we’ll see what happens. Customer Service is good albeit I still have nothing to show for a $100+ purchase after two months lol. Hopefully it was just a accident and I can begin shopping here every week.

Well, it’s going on two months since I placed my order, and two and a half weeks that it’s been in customs. Communication has been fine, and a Reship is supposedly in the process of being shipped. Will update review when/if it comes through.

Highest potency our lab has ever tested. Everything done by these nice people with the utmost of care. Hoping to see the same quality continue.

Product was exactly what it was supposed to be, and it shipped in just over a week to Europe! I recommend these guys for everyone looking for a great product and awesome customer service..

Amazing as always, purity, Timing & overall experiences!!! Thanks again RCB!! You have provided our small research group with more top-notc, lab grade chems with incredible purity compared to other associates and after researching your products, they said that they’ll most definitely be contacting you for bulk !!

Firstly thank you for shipping out quickly and for the professional packaging. We are happy with the product and service we’ve received!

good stuff! good customer service. Research went great. RCB is the place to go!

RCB never fails to deliver a high quality product with excellent stealth. A great supplier!

Finally a reliable and trustworthy supplier for research purposes.The quality is top notch and they stand by their word with multiple options for shipping.Never had a single problem.

About to order again first pack landed so there legit ATM purity to par with other clam ordered but not crystal then powdery packaging was annoying but don’t mind see its great time on shipping a bit long almost to reship but they they responded to emails within 48hrs so can’t complain

Made multiple orders from rcb, always very good product. 6 orders one got seized and they promptly reshipped my order. Top notch product and customer service, wouldn’t order from anywhere else!

Iv been using these guys and gonna put more into them because they got the best, I have a larger then normal order will even update for doubters!

Top notch comes thru every time, no bull site

Package delivered on time sorry for bothering you guys, I appreciate you guys. Quality 100% and it’s testing out great! your company has great customer service. Thanks very much!

Be very careful!!!!! This is the best of the best! Use care when handling. .1-.2mg is enough any thing more and ….. what happen?! Almost was fired due to lack of knowledge of how potent while undergoing research.

Worth it! I ordered it twice I was so satisfied.as for shipping, I love the way you guys do it. Shipping fast all considered!

I’m glad back in business. Looking forward to receive first order. Great customer service

Amazing stuff all my lab rats loved it. Recomend highly!

When I came across “RC Best Sell” during a Google search for a new source for CLONAZOLAM – my current main focus in my research, I thought the name and the prices and how you used to be able to pay with PayPal was way too good to be true. It took me months to convince myself to send the crypto and see if I would receive any of the products I ordered – being of any quality at all- or if I would even receive any products. Within a few hours of paying my crypto I got my confirmation email, and a personal email saying not to worry that I had not quite sent enough money to cover the crypto fees (Aerospace and Chemical Engineer here, still never get it right). I didn’t even have time to get worried enough about my orde to check my tracking number before my package of what was labeled Clam, 2FDCK, and FLam arrived 11 days after I paid an insufficient amount of money for my order. So being who I am I immediately jump to the conclusion that all of these powders are fake or mislabeled because the CLONAZOLAM was pure white and more crystalline than all other 15 times I’ve ordered grams of Clam. Clam is usually canary yellow. Having a background in chemistry I do realize that different synthesis procedures among other things can effect things such as the color of your final product. I am analyzing and researching now but I truly believe this clonazolam to be white because it is so pure/ may have used different synth which does not leave behind the yellow that I now believe to be an impurity in 90% of the world’s Clonazolam. I believe this because of the ease of solubility in either ethanol or PG was markedly easier, suggesting a more pure product. Also it makes absolutely no sense that the absence of the yellow tint is due to an impurity. Could be incomplete synthesis, but no. This is the finest Clonazolam that can be found on the planet. It leaves my research equipment noticebly less corroded, and my lab rats experience very little body load and bad side effects that are generally due to impurities. This Clam is 98%+, for pennies, in days, guaranteed. We must all do everything we can to make sure RCB stays around and functioning to this level. I had never researched 2FDCK before so I cannot compare, but can say that it is an absolutely amazing product that I also would believe to be 98%+. The Flubro….. Bro this is the gnarliest benzo on the planet, prepare your equipment and start research with rats at doses you would think you would give to something the size of an Ant. The Flubro is 98%+. Thank you guys so much for what you do and allowing us to entertain ourselves in the way that we choose, and that we enjoy, like human beings should be able to.

excellent research chem for my lab rats, will be back

VERY EXCELLENT SERVICE! Very satisfied with the quality and speed of order

Excellent quality accidentally ordered a sample and order was too large so I may have been best..tOP QUALITY

First order, went extremely well. Packaging was on point too. Good synthesis and came with a free sample too! (make sure to add it to your cart). Highly recommended vendor.

Amazingly high quality, I love it wyen the pure crystals i get instead of the crystals being crushed makes for waaaay easier research! Super potent use lab protocol/gloves and eyewear when researching!

Very potent always use proper protection/lab protocol. Amazing quality more promising chem to research than id have thought! Would definitely recommend

Amazing quality and research material! Would recommend

Great communication and product. Doing a second order and plan on making a much larger order if this package is as successful as the first. 5/5, great company.

etizolam was high quality, the

This is the best high grade research chemicals right now.

10plus! First order. First from China. Hope they stick around. Been researching many years so seen a LOT come and go. Just wish they stocked more dissos.

The best imo,I couldn’t believe the shipping speed everyone kept telling be patient so I was and it was here in like 7days West coast.Very solid product, once again the testing results were much much greater than expected pleased again please stay rcb forlife!!!

AMAZING price, AMAZING product! 🙂 Would give a 7 Star review if I could! I Love you RCB family! 🙂

Excellent, Excellent, Excellent products. Arrived fast, discrete packaging, FREE samples [Thank you!!!] EXCELLENT PURITY. “Gentlemen, this is no humbug.” [Agree with others…labeling is problematic. I ordered 10 diff products, ended up with 13, (thanks again!!!) but only one letter on many bags so I have a giant puzzle to figure out.(8 I cant ID yet but the 5 I did ID : WOW!!)

Wow. My rats where in. K hole. Experiment total success. Rcb is the BEST. Do not purchase your research chemicals anywhere else. Best shipping, quality, and service. Thanks!

Awesome shipping speed wieghed over and was definitely top notch quality this is a real review solid products here.?

Great stuff! I love RCB. They treat you right! Just be patient on the shipping folks.

I just wanted to let you know that I received the package and everything turned out great. You will be the first person I recommend to people I know!

Order number 2,. Safe and happy, about to place #3 couldn’t be happier. Will update, on arrival! Thank you RCB! Keep up the amazing quality and affordably. Thank you friends!

5/5 my friend. Message me. Hey this is crystallized and I’m fact worth it. I hope you will always be in stock of this. Don’t forget me!!!!!

5/5 my friend. Message me. Hey this is crystallized and I’m fact worth it.

5/5 my friend. Message me.

Good quality, just what I needed for my taper. Thank you.

Amazing! Wowza! Got here in 13 days!

Received. All good.had to sign but understand why.though no free sample. Oh well

Very potent so handle with caution! Amazing stuff to research though and quality is amazing as usual with RCB! Please never leave us RCB, the research materials here are far superior than elsewhere! And delivery frim date of tracking number received to US midwest was 10-12 days

This chem is a unique chemical with amazing properties. 11/10 for me and 10 days shipping from date i got tracking to US

Amazing stuff ti research! Highly recommend, took 10 days from tracking number to me in the US

All around great haven’t tested purity . But lab rats like it. Only thing is etiz gets stuck to bad and you lose some mg’s for sure still give 5 star made 2 orders and both came 15 days love these guys I will spread word

Order once again came in 2 weeks I feel this time the etiz is more potent

A

Very pure potent material,handle with great care

Great chem,long lasting,great tapering

MEP by itself did not induce any toxic effects upon lab rats. MEP with MDPEP has caused some visible nausea via puking and some visible dysphoria. MDPEP gets destroyed at a lower temperature than MEP. Great Service, Fast shipping, quick responces when asking for tracking number or having a question about the order.

Fantastic batch. Your synthesis isnthe best..ordering more really soon.

Excellent customer service!! Great as always!

Always had such good experiences with RCB!!!!!!!!! 🙂 Orders come faster every time! RCB are really nice people and gave a sample of this which tested out beyond words to describe, You would absolutely have a very good time seeing the results for yourself! RELIABLE, LEGIT, AMAZING! I do my research and this is >99% pure like they said! THANK YOU RCB family!!!!!!! 🙂 🙂 🙂

heres a 4 star review for you thomas….just so you dont see all 5 stars i guess i hear what your saying but these guys will not let you down. Go with the 2fdck. this flubromazolam is not for low tolerences. my machine registered almost pure. RCB FOR LIFE. I have been researching in my lab for over 10 years and these guys are my go to.

i have been in the research community for over 10 years now and TRUST ME when i say, this is the BEST 2fdck you will find ANYWHERE! customer service was on point. got my order in 10 days on the east coast of the US. i dont understand the negative reviews i was seeing online last couple months. Very honest people to do business with And goddamn was the package stealth came wrapped up in like 6 different bags. I will be ordering this for research in Quantity all i have got was a couple free samples and they were all A++++++ tested in my lab. thank you RCB. anyone who says they scam dont bother wasting their time. Because these guys are VERY reliable. Many many more orders to come

Once again thank you for your high quality For. Highest Purity of any other vendor we’ve tested for.Kept the same high quality for years!!!

Great stuff. Look up the K trials being done by the NIH into how much this helps neuroplasticity and depression. Fascinating stuff and RCB does an amazing job of getting this material to your lab.

I can definitely say I’m 100% satisfied with the communication, shipping speed, and quality of this product. Received my order in 11 days. And plan to place a new one when certain items are back in stock

This is the best there is. Quality blew me away along with the communication from the vendor. They know what they’re doing and they do it well so don’t worry if you don’t receive your pack in time, it will get to you!

Amazing service as always if anything it’s improved! Great compound with slot of research on potential in the right hands. Rcb, is the only source I trust with my research! Top notch shipping and packing too! I don’t understand why anyone would complain about there private parecels! Already reordered!.

Thanks you guys for everything! Not only are products great quality but customer service also is very great!

Just got in today took about 15 days to east coast. Great stealth.

Bought multiple times, was skeptical first time. But the communication is unparalleled, and the product is top notch, RCB dont mess around,.

I ordered a variety of products off of RCBESTSELL, 2-FDCK being one of them, and the quality was excellent for all. The entire process from order to delivery went flawlessly and customer service was very responsive to any questions I had regarding my research.

Quality product. You get exactly what is advertised and the communication and shipping went seamlessly.

Quality product. You get exactly what is advertised and the communication and shipping went seamlessly. 10/10

Can’t wait to try products

The research went well and the product was of high purity as discovered through analysis by Reagent Testing. Communication and shipment were topnotch, as well. Would definitely recommend.

Love these guys… perfect sizes and prices for my small lab. I am about to order some other products. I’m definitely staying with these guys. Trusted. Reliable. Great prices. Except to wait for it, but it’s worth the wait.

Funny how none of the other reviews pertain to the product – Flubromazolam; all the reviews are about giving this site as much flattery as possible. Let’s see if a non-5-star review is made public before I make my order here. Oh, by the way, would it be possible for you to put the powders in tablets or pellets?

Best product available for a long time! RCB is amazing! I have made 3 orders and all were shipped smoothly and the products always genuine. Won’t go anywhere else for my research needs! A+++++++

Such a beautiful outcome with all research and testing done with this product!! I wouldn’t recommend anyone else but RCBESTSELL for research needs. Menu keeps growing and loving all the new products. Can’t wait for my next order to arrive;!! These guys are a verified ” Top Shelf Chemical Supplier” without a doubt. Love you RCB !! I keep thinking I’ve researched all products but you continue to surprise and amaze me with the new products!! Keep up the good work and you are the #1 supplier for all products you carry and I’ve referred so many people that are in need of a legitimate company that follows through consistently. Purity surpasses expectations EVERY TIME and our group has been researching your products for about 4 years or more and you have not let us down yet, and we want to thank you sincerely for ALWAYS coming through for us!!

Quick ship and also the purity is legit.

Wow shipping is fast. Good stealth packaging and research continues to prove quality

Amazing research product. RCB products are all the best kind!! I will back every one of them because me and a couple other researchers have now been able to do multiple studies on all products and they are always of the highest quality, not even comparable to these other vendors…. Don’t waste the time or money on anyone else for your Research needs.

Highest purity anywhere along with unbeatable prices !! Could not believe how pure it was !! Love RCB and they seem to really hook up their loyal repeat customers

All im going to say is hands down best research vendor for 2-fdck. Purity is amazing every time so I had to leave a review here too !!!!

Very pure!! I’ve researched this product from so many vendors and none have been better !! Hands down best quality Flu-Alp !! Never order from anyone else after the first time researching. Definitely use Harm Reduction when working with this substance… Purity is always >%99 !!

Absolutely perfect !!!! Tested off the charts multiple times !!! These guys are the real deal!! Thank you again for your services RCB. Best in the business with all products they carry. I’ve now got to research all products and all have tested to the highest level of purity. Been a loyal customer for years and I will always refer people because they are very good to their loyal customers

I just got my first batch since I saw it added to the menu. Purest Tia I’ve ever had the pleasure of receiving !! Shipping only took a couple weeks!!! Price is better than anywhere else right now other than wholesale/bulk!

Took about 40 days for it show up to the east coast but the product came and very satisfied with it. even though they did say 15 days.

Said it made it through customs last night on tracking. Should get it in a few days and hopefully its the real deal. Ill leave a follow up soon

Excellent quality, mine initially was stopped but the reshipment came quickly and easily. RCB is the best!

shipping took 15 days to Midwest USA, stealth packaging and high quality research material. Would like to see the CAS info for this one and will definitely be trying some other RCB products soon!

Less than a week to UK! The free samples had been open and taken by UK customs but the main product was still there so confusing, but fortunate! Amazing product, very hard to get hild of this stuff nowadays but this is the real deal. My favourite RC benzo by far. One 8mg dose had you smiling n floating in serenity for 36 hours. Can be dangerous if not taken with care and in the right doses but done correctly its like diazepam and temazepam combined that lasts for well over a day. Stick to doses between 5-10mg and youll be fine. Doesnt start kicking in for several HOURS so do not redose thinking it is not working (im deadly serious, thia stuff takes like 4 hours to get to peak plasma effect)… So be warned. Enjoy

Received my package within 21 days of order. The quality is is top notch! Research has shown to have best results yet. Highly recommended

5 STARS! If you are in the US and thinking about trying one of our domestic suppliers such as NOM4D1C, don’t bother. Most of those guys are just scammers. Just us RCB ONLINE and save your money. Product received was perfect and took 13 days to get here. I’ve never had a bad experience with RCB ONLINE. Customs is the only issue you will likely ever have. But they will reship, and now for free! Seriously, DO NOT mess with US domestic suppliers unless you know them. They will take your money and send you nothing. RCB ONLINE will not. Just be patient and wait.

Great product exactly as described, quialty is above and beyond, shipping took only 11 days to USA, will defy be ordering again very soon, RCB is the best, I hope they stick around for a long time!! If u are scepitcial….don’t be, they are 100% legit… safe researching everyone!!

Perfect order, timely, etc, however the substance itself was unfortunately completely inactive in any test I performed. I do not recommend further study, unless I was seriously missing something.

This was exactly what I was looking for. Reminded me of a similar ADD/ADHD compound I’ve studied before but I cannot remember the name. I’m studying ADD & ADHD substances, so this worked perfectly for me as a research product!! ? Thank you again for everything RCB, you’re the best in the biz!

The best of the best of the best. Just got my 5ifth order. The longest was 18 days between receipt of payment and getting the package – usually no longer than 15 days.Strealth is so well done that I’ve never had a product inspected. Etizolam is BETTER than alprozam – faster onset, less sedating if you’re being social or active (but puts you straight to sleep if you go to bed), you feel more ‘with it’ even though you are in anxiety free bliss. Shorter legs than Alprozam, so I don’t feel groggy the following day. Speediness & Comms: 5 stars. Always receive a response, always get a tracking number and my order is always at my door in about two weeks. Overall: the best RC vendor on the net bar NONE. They even customise my customs declarations for me. A few orders were a little light, so they gave me the missing amounts in my next order. Who does that? The best RC vendor on the planet does! Let’s support them the best we can. They earned it. I hope RCB never go away.

As effective and pure as diazepam powder. At my door 15 days from order, and began experimenting. It’s like-for-like. Fast, secure ordering, trustworthy team, discrete packaging and your order Is in shipment that afternoon. You literally can’t beat these guys for reliability and speediness ad quality.

Got it as a free sample with the rest of my research products, and wow, did lab results blow me away. Near zero impurities, its all crystal (as it should be unless it’s been cut down) and I was very happy with the results. Will be ordering a 5g order shortly to stockpile for days of heavy research where a lot of product is needed to conduct the experiments we do.

I ordered 5 grams of 2fdck a month ago – I purchased 5 grams from another vendor last year and can confirm that this batch is very high quality. There was a small problem with shipping, and since it was my first purchase from this vendor I was concerned, plus I wasn’t getting shipments from other vendors recently. But the staff communicated with me quickly by email and assured me they would get the package to me and it arrived shortly afterward. Great service, Great product. I will be buying 25 grams next asap.

Excellent! Got here in just under a month like my last order, perfect packing, RCB has excellent reliability and went above and beyond to help make sure my order was satisfying! Think they might have given the extra G that they gave me simply because they were out of stock of other RC’s for a while, they are cool like that 🙂 Will be a customer for as long as RCB is around! Quality is excellent, so please keep it safe and use harm reduction and smart lab practices with this one, it is exactly as the description says! Thank you RCB!

At first i was skeptical due to there being a high # of new customers (+likely orders from) which caused a slow going order fill but rcb kept in contact and everything went spectacular!-product is exactly what i+you are looking for!-if your in deep enough to be the brave soul to even mess researching such a pure potent triazoloBZP…wear a respirator for real!-scarier than straight F….dont doubt RCB dummy!

Package finally arrived. Although it did take about 2 months and some technical issues with the shipping, I am very pleased with the customer service and the product. RCB was extremely professional with great communication and getting the packaged reshipped. Thanks so much will definitely be ordering again hopefully I’ll have better luck with the shipping, but considering its from China 2 months is understandable.

Researched a sample, will definetly be buying a Batch for my next experiment. Thanks!

10/10, took a month to US but that’s because customs held it for 2-3 weeks. Word of warning, customs TORE through this stuff prob to test so definitely give it 2-3 weeks once it hits customs before it ships to you if in US. Will be repeat customer!

Excellent stealth, product quality is on point. Was my first order and will certainly not be my last

Very pure, so be extra careful dosing. A fraction too much and you will either oversleep or act very drunk, but you have no idea. Hate reduction. Best Benzo I have ever had.

Quality product, my research shows this is like a more potent 3-fpm,smooth long lasting functional stimulation

RCB is, without doubt, the most trustworthy vendor with me quality products and always responds to my emails. This sample was received and research has begun. Thanks for sticking around RCB!

Took exactly 3 weeks for order to arrive but it completely knocked my socks off so despite some uneasiness that it was going to be seized, it landed safely at my door and the price and purity absolutely made it worth the wait. Best RC source on the planet right now

Super on point for all of them, they could be labelled clear to know which of the fl bags are wht, still amazing price and fast delivery.

RCB is by far the most trustworthy vendor. Always get my RC’s within a few weeks after ordering. This chemical wasn’t my favorite to research but Rcbestsell certainly is.

Chose as a sample, but research proved to be interesting and satisfying, that it’s been proven well worth being a primary order, material grades excellent. Service and support has matched

very impressed by your timely manner and your awesome research chem. I wanted to tell you thank you! Thank you, kindly, very appreciated! 🙂

RCB is the best most high quality vendor out there right now products are top notch response time always A+ and always willing to work with you..!!

Excellent service, response and quality research materials as promised. Looks as though since I placed my order, the sample pack now contains an additional 500mg sample of Metizolam, making it an even better value. Shipping time was reasonable, no complaints

Solid stuff. Solid vendor!

best using glovez, safe when respected, goes with all research of course, be safe.

Best Quality, best service fast also. safe checms too, no F, i appreciate the safe procesures and ethics.

Great product couldn’t ask for better very pleased!!!

Took a week and a half to arrive,very good product no issues at all,great vendors.

Order #3: SUCCESS! I have dabled with many of this sites products while researching and this right here is the real deal. Can’t say it enough, you’re getting exactly what you paid for.. I’ll be stockpiling for my next order, just in case it tragically disappears from the market one day. OVERALL: 9/10 Shipping to United States and 11/10 on product quality. Thanks again guys for coming through once again. If anyone has their doubts, don’t.. because you’ll be missing out if you pass this site off as a scam. It’s 100% official

Friendly and communicative. Order dispatched in less than 24 hours. Packaged so beautifully I almost hated to cut it all up. Total professionals.

Havent received my flualp yet just waiting on tracking. But i felt like i had to give them 5 stara, because of top notch customer service and all the positive reviews. I will post reviews on my forums iam apart of, and on here once i runn it throufh the lab. RCB are very helpful and they stand behind their business. Will update soon. Now that i figured out how easy bitcoin is i will be ordering all the time…real review to come

This is amazing! love this offer from RCB!

Just got my order and it is spot on + high quality. I will be recommend you to everyone I know of with similar taste. Thank you for being a trust wothy source and I look forward to working with you in the future!

Favorite Chem! I ordered first late year in summer,got here in 15 weeks after, placed second order and was patient but no movement for a month. Contacted customer service and they gladly reshipped. Can in 2 weeks.. patients people

Got this as a sample, yes it’s not yellow like some think but I’ve had White C-lam before and it was A+. So the sample order I got and is super!

Best on the market period.

Ordered this recently and also received a sample. Very nice quality product

Hi guys sounds like this place is legit, in going to order some clam as soon as my lab has funding.

Testing is going excellent. Top notch vendor right here, The Clonazolam is great too!

BEST chemical this website offered. If they got rid of EVERYTHING else, but they still sold Flualprazolam, I would still come here to buy. It is solid. They completely destroyed that other site.. what was it.. RConline? I don’t remember.. Those guys who used to sell only benzo’s but had a terrible attitude. I can’t remember the name.But they sucked. I am SO glad there is a site like this. I only wish they offered higher quantities. I love this site. It’s my go-to, I assure you. STAY ONLINE, RCB, You are my heroes! 🙂 Flualp is the best on the market, I 10000% promise that.

Great product. I ordered during Chinese New Year, and I still had it at my door in 2 weeks. These guys are smart about OPSEC, and I’ve already make another order

So pack came in about two weeks at to be honest at first I was a lil weary because I’ve always been used to the yellow flour texture kind and this just had a tint of yellow to it and was very small crystalline but come to my surprise it tested to be some of the best clam I’ve ever had and I’ve tried just about every vendor out there some still around still some not they packing is amazing they hook it up give free samples discounts shit what more can you ask for and they carry some of the most important rc’s Out there right now at a good price by far only vendor I will deal with unless it’s something I need he doesn’t have but I definetly recommend they get a 10/10 in my book for every catigory….!!!! Love you RCB!

Very high quality product, will purchase more soon!!!!!

Took almost 1 month to arrive, but it was safely kept in their excellent packaging job. The test results have yileded that this is of superior quality and with accurate formulations and quantity. Quality research material if your time constraints on results are not too short. A+

Thank you so much package arrived today! Super fast shipping will look forward to buying from you in future!

Best ETZ I have ever worked with, hands down! I have worked with this product, in powdered form, for over 6 years. Lost my domestic supplier last July,thought all hope was lost. I have used a few, but stuck with one main US based one until he had to shutdown. I was quite satisfied with that product, but RCB’s surpasses even that one, by far! I did have to do a reship, as my 1st order was placed on previous site . But, once I waited the 30 days and paid my reship fee, my product arrived in a mere 3 weeks! And, with the current stealth and shipping, I don’t forsee needing to do a reship anytime soon! You will need to sign for your package-do not fear this . It’s part of what makes the whole process more efficient, and safe for us, and RCB! For those confused by using BTC I use LibertyX to find a local store to buy BTC with cash, and it is in my wallet before I walk out the door! I pay the “fast miners fee”. From that point, it’s just a matter of copy and pasting wallet addresses, and you are all set! I have no affiliation with this company, aside from being a new, true blue customer! I left a few reviews on a popular thread for this company (on another site) using this same name. I reviewed after 1st research, and an update 2 weeks later. Let me just say, the more research I do with this product, the more I love this product! Very pure, very PGA soluble. I highly recommend using a volumethic method with all products like this. Help keep our community safe, and out of the attention of 3 letter agencies! Ok, I have rambled enough. Lol RCB rocks!! They are 100% legitimate, polite, and professional. And, product is absolutely the best I have ever worked with! Like i said i worked with this product for many years and many sources, but now I have found my new go to source! Thanks RCB, you guys are amazing! I will buy from nowhere else as long as you guys are around!

FIVE STARS ALL THE WAY!!! My device would not allow me to click the 5th star?! I tried over and over, but was only able to hit the 4th one, so I am staying my 5 stars. Lol. I’ll rewrite a review if I can hit the library and perhaps hit that 5th star! Anyway: Top notch ETZ!!! I can honestly say that this is THE best powdered etizolam I have ever researched! And, I have worked with this material, from other (lesser quality) suppliers, for around 6 and a half years! I will absolutely be buying again, very soon! This company is 100% legit, just be patient as your order may take a few weeks to arrive. And fear not the required signing for your package, it’s security for you and RCB. Shipping is ultra stealth, and I don’t see shipping being an issue any longer (as needing a reship). I have left a couple reviews on a popular site with a thread devoted to this company, as well. I reviewed the day I received package, and did an update after 2 weeks working with this product. I have only become more impressed the more I have worked with it! Please give these guys a shot, you will not be disappointed!! RCB, you have yet another new true blue fan! So glad I found you guys! Prices are great, too! And for anyone that finds the BTC pay option complicated, I use LibertyX to buy BTC with cash locally and it goes right into my wallet, before I even leave the store! Makes it super easy!

I’ve been doing this for decades and it doesn’t get better. Highest quality research materials. I ordered during their New Years and never got a tracking number but never asked for one because I knew they were honoring their holiday. Got material in 3 weeks to west coast U.S. Packaging is totally stealth and in 4 layers of vacuumed packed foil. Just amazing how professional. Please treat them good so they’ll stay at it!

First time buyer on the site and very excited to get some of this Clam. The past reviews make it sound like the quality is pretty good. I will update once I receive! Thanks!

Great vendor! Easy to work with, prompt email responses quick shipping and great product. This will be my third order with them. Highly recomend!

Excellent service and quality material.

Quality 10/10 – shipping was a bit odd, but fine. overall 10/10

Greatest quality ever researched! Best there is!

Only complaint is the powder likes to stick to the side of the bag, unlike, say, clonazepam.

Received as free sample. Will probably be making full order soon.

Great product, amazing stealth , and very communicative staff

The purest i’ve come across in my research. Weighed over and was packaged great. My shipping took longer than I thought but it was worth it. Im sticking with this company! price is great.

This etiz is the shiz love looking at it under a microscope as well as testing its purity

3 weeks then 4 in customs. Finally arrived. Happy

Beyond good. Christmas and all. 3 weeks get to customs and 4 weeks total before I got it. They had tape on it saying its been checked. Here it is.

Subsequent batches of Flualprazolam never disappoint. Fast, polite, & reliable service – that’s what to expect & what you will get. 11/10 in the current RC market. Many thanks!

THE FREE a sample proved POTENT. Keep the lab equipment safe abd unplugged once in awhile this stuff is nooo joke. 5 stars!!

Got a sample of this on my last pack On a whim I had never really “gotten” dissos having tried dck and 3meopcp before and not really clicking with them. Must have been about a 250mg sample tested about 50 then 50 more it was great stuff. I was out by the end of an afternoon but wowee I finally “got” dissos everyone’s been saying that first batch has been top notch and I agree.

Today my order came in the mail, everything in excellent state and perfectly packaged so thanks!

Awesome quality. Way faster than expected. Research showed product to be very pure

Excellent product and extremely fast shipping

This company I’ve been working with. Me and the Boss super honest and. Don’t worry about the policy for a tracking #. It’s not a scam trust me got my parcel 9days!

The flualprazolam(ordered a gram) was 10/10 I also received a 300mg sample of etiz w my order. Will def. be a returning customer great service.

Fantastic research product! Top notch – trusted vendor indeed!

Product was good crystalline. Weight was correct. 13 days from order to door. Can’t beat that. Thanks!

Justabout perfect from quality, to packaging & integrity of the product. Nobody does it better!

Shipping so fast, stealth so good, quality to match. Even got some extra. The only way to go!

I feel like this is it real life because I just don’t understand how there’s so many scammers out there, but these guys are beyond legit. I got a sample of this and I will definitely be ordering more!

Shipping was fast, and discrete. I had an issue with my order and unlike are there research vendors they would just take your money… They really stuck with it and made sure I got my package so I can do my research in the lab. Just as expected, my lab results were beyond good.

This was the highest purity 2fdck I’ve ever purchased and have done so multiple times as it is great for research. Great people to do business with

They are legit. This is a great company. Great customer service and can attest to the quality of the etiz. Can’t go wrong here folks!

A wonderful, high purity product, it’s doubtful one could find better. Amazing commununication and customer service; my order wasn’t straightforward; it was kind of complicated but it was no problem for them. Arrived overseas in a week max, maybe less; by EMS (IMO best overseas carrier)

RCBestSell is number one in the game right now. Absolutely pure, amazing stealth, fantastic results. I won’t be using any other supplier. Please stay online for as long as possible, RCBestSell! You’re among the best in the 10 years I’ve have experience in this scene. Second order queued up!

This Diclazepam is of perfect quality for performing research. I had great communication throughought the order process which involved multiple chemicals and not exactly straightforward, but I was understood perfectly. Shipping was possibly the quickest I’ve had (EMS). I could not be happier with my order, not to mention the wonderful price.

Surprisingly quick shipping! Will definetely order again

I left the long review where I didn’t think the vendor was honest and honestly this is one of the best RC purchases I’ve made.

I’ve used this vendor twice now. Well, since I like this vendor so much, and the way they conduct themselves… I have been telling everybody about rcbestsell. So you can’t go wrong with rcbestsell, and the etizolam is a very high quality. Lab tests confirmed through gcms and NMR analysis. Thanks rcbestsell!!!

Got a generous sample of fl-alpra. Communication was great and despite my natural tendency to be anxious the product arrived just fine. These people are professional and honest vendors.

Delivery came the day I was about to run out of my research supply too. You guys are life savers! I haven’t tested the product for my Daoistic-driven scientific interest yet but the packaging was very safe, both for the customer and the postal workers (for those that fear that these research compounds may leak out of the package and come into contact with their skin — it won’t, trust me). The stealth is very excellent and the order came when expected as stated by the tracking. Thank you so much comrades! We really need to cut down on the authoritarian bullshit that the governments of the world are imposing on peaceful people. It’s bad for those both in power and those without. We all need to let go of our egos and let people do as they please so as long as they maintain peaceful relations with others.

stellar.

Very satisfied with the customer service and the etizolam. Research shows positive results, took 2.5 or 3 weeks for delivery but packaged very well. Thanks!

Fast service. Super discreet. Good comms and the quality is superb. Thank you guys.

Just as described

I loved everything about the product except for I didn’t check to see if they’re going to be on vacation or not and shipping took a lot longer than I anticipated. Other than that, a okay.

The only problem that I had with the order was that happened to order it on the time they were on vacation so it took about a month to get here from the time I ordered. Other than that, packaging was slick and there wasn’t any problems. Definitely want to come back again someday soon.

My rat forgot it’s name. Research is fantastic!

This is an extremly good product that is easy to order and a good ptice

Well-priced and securely packaged quality product that serves my testing purposes, along with an exceedingly efficient order process. (NOTE: There is a (mistaken?) section about BK-EBDP near the beginning of the page prior to the comprehensive info about Etizolam. If reviews can be edited, I’ll remove this note obviously (or administrator can), or if not I’ll remove and rewrite if possible.)

Great communication and timely delivery especially taking into account the distance it traveled.

Some legit stuff. Research went oh so smooth. My rats questioned reality at one point.

very high quality etiz. My research rats seemed to enjoy it.

Most pure and fastest delivery from any overseas site I’ve used

The product is of the most purist quality.Other pics in the review section show what I received and I can say I am pleased. RCB FTW!!

So har sar so good

To be honest the tracking just showed it setting in China for like a whole month so I thought it was a ploy to get me to pay the 29 buck for a reship. That’s not what happened at all. The product made its way here safe and sound. Also the mad scientist which whom I communicated with was very polite and honest. Honestly I thought he was a lier. Shame on me. Order with confidence folks this vendor is the real deal. Just be patient your pack will show up. Thanks RCbestsell. I’ve slept like a baby for two straight nights and for a true insomniac that’s amazing.

My first package was lost at customs, and they received shipped and order recived in 7 days to the usa. Amazing service with great prices. Am placing my next order now!

Long lasts, use caution when handling

Only 9 days to ship to the US! High quality Diclazepam!

High quality research and development chemical at a competitive price. Ordered on 8/18 and arrived today. Only two weeks all the way to the east coast! Really fantastic packaging. Highly recommended site. As always, research responsibly friends!

I’ve done a lot of GS/MS testing, all thst crosses my mind RCB can’t be beat. Even when you make an order they throw a free sample of another product. The best part this guys solid and if you buy more they throw extra gram or more. RCB got the Legal RC’s on lock…. My lab loving it

I’ve done a lot of GS/MS testing at my lab. Wow this stuff rifht here is the super fire this is by far the best company.they always hook it up never short. Weighs on point btw to be honest it actually add a little more bigger order get an extra gram 🙂

Excellent CS. Very Responsive. Only thing is I’ve never seen crystalline Clonazolam. I’ve seen white flour texture and they most common yellow but this almost looks like Etizolam. Doesn’t stick. This is a great service though if you get by customs. Took 10 days total!

Best Purity, great product and a friendly trusted vendor.

GREAT SERVICE, EXCELLENT AND FRIENDLY STAFF. NO BETTER IN THE BIZ FOR SURE.

Received exactly as described without issue

Good quality

Since the demise of US-based companies, this was my first shot at ordering RC’s outside of the county. I decided to be safe and buy a few samples, and all I can say is I’m overwhelmed with the entire process. Research has produced great result, tiz is to notch, order arrived perfect to Midwestern U.S. in just 10 days! (including a weekend) In addition, customer service has been helpful and responvive through the entire process, even answering post-shipment questions. I can’t recommend RCBestSell enough! Thank you!

This came rather quickly considering it was from China, but it was well worth it. The Clonazolam is top knotch.

Habent had a chance to test the product yet but it looks absolutely perfect I was shocked at arrived in 8 days to the west coast of the US they were great with communication I’m not a professional when it comes to dealing with Bitcoin and they were helpful and prompt packaging was great and discreet and arrived here quickly like I said. I’m actually lucky it arrived here at all not RC best sells fault at all but my mail delivery guy delivered it to the wrong mailbox! luckily an honest person saw a package that wasn’t theirs and dropped it off to me at my house who knew there were still honest people in the world! Anyway I will definitely be ordering again the sample was a nice touch and appreciated price was great and I didn’t even realize you could get a discount for using Bitcoin so I didn’t use it lol. thank God there’s a good reliable vendor out there for clon!

I wouldn’t think twice about ordering again. Perfect service.

Perfect product. Is what it is supposed to be, and fair priced at that! Will certainly be back!

From ordering to delivery it was less than 2 week. You’ve exceeded my expectations. I just wanted to thank you. Will be ordering again soon. You guys are the best!

10/10, that’s all I really have to say. RCBestSell is probably the biggest reliable vendor out there.

This product definitely has top quality and was much better than my other shipper’s research.It was shipped the same day and I received a tracking number within 48 hours. I received it in about 11 days and I’m happy with that. Great packaging. Great quality product and a returning customer. Thank you for your services to the research community!

Fast discrete shipping, was indeed compound it was meant to be.

Very pure stuff by mass spec confirmation! Couldn’t be happier! Also, very discreet shipping.

Product is top notch and shipping only took 7 days to canada

The product Exceeded my expectations, and that’s not an easy thing to do. When ordering and shipping the gentleman that you deal with is amazingly professional, polite, and friendly. Order now! You WILL NOT regret it!

Delivery took about 13 days, no problem with custom,packaging was discreet! quality was top notch! very pleased with this service, thank you! will definitely do more business in future!

To be honest this Clonazolam was highest quality I ever met! Delivered in very discreet packaging. Better price and customer service than anywhere else. highly recommended!

First of all, the customer service is excellent. All of my emails were responded to within 24 hours and were very helpful in placing my order. The product seems to be testing pure for my research purposes!

It took around two weeks to travel from China to eastern US. I received a tracking # after a couple days and began tracking it. After two weeks, it was finally delivered! Research material is of high quality and lab tests indicate that it the correct chemical. 10/10 Would order again.

It took exactly two weeks from the time I wired money to the bank account for the package to show up at my post office, the packaging was very stealthy and I had no problems opening it. This is some of the highest quality flualprazolam I have purchased on the internet. I made it into a 10 mg / 1 ml solution with propylene glycol using hot bath and agitation with stirring, it took a while considering my solution was so potent but as I said before the product is top-notch and the customer service is great, every email was responded to except for when they went on vacation and the only thing that I could possibly think of that would be better is I didn’t get a tracking number but once again that’s probably because they were on vacation. Definitely going to buy some more Products off this website thinking about doing some research on u4-8800 next. may even get a sample of one the cathinones for further research

Was so shocked made my feet drop, when test the purity of this. Fast delivery and by far best Legal RC Company

prpduct was top quality and customer service aswell. will order again.

Your not gonna test anything better then RCB Clonazolam period. Fast delivery prices are super fair. Can always count on them! Great Customer Sevice!

delivery quick and fast! you want top notch purity this is is the website! RCBESTSELLS is unbeatable! My test showed that I’ve never seen nor had anything like this to test at my lab. RCB Clonazolam is the purest Form. 🙂 will be working with them for a while!

Weight was right on point! Took about two weeks from order till door here in US but went through without a hitch!

Product was high quality. Delivered in very discreet packaging. Order placed on July 8th, arrived at my doorstop on July 20th. Even got that 10% Bitcoin discount, highly recommended. Better service, price, and quality that anywhere else I’ve seen. Would definitely recommend to a friend. A++ GO RCBESTSELL.COM!

Package arrived yesterday no issue.quality test is GOOD! Thank you very much!

Research went perfect. Great product

Research went great! Very pure and great prices! Thanks!

The etizolma was as pure as I have found. This company truly delivers what is stated. Will always use their compounds for our research!

The product I received is very very top notch. Also the customer service was excellent. I am definitely ordering from rcbestsell again and you should too. Dont listen to the bartards on reddit and just be kind to anyone from the company you communicate with.

I just received product today. Your shipping was fast and customer service was excellent! Purity test is great!!!

Shipping took 3 weeks but it’s from China so it’s expected but pleased with the customer service

Reliable source and great product!

Placed a sample order June 8th, landed June 22. No problems on the way here (California), great customer service! White crystalline powder and is undergoing test but product seems to test out A+ Looking forward for sample order of other chems I will place in the near future. Recommend!

Most detailed precautions, sould be observed while working with this, everything the description says is very accurate.

diclazepam tested to be pure. Received package in USA and only 11 days from the day I placed the order. Great communication with the seller. Very respectful and professional

Product tested to be pure. Received package in USA and only 11 days from the day I placed the order. Great communication with the seller. Very respectful and professional

great production

This FLUALPRAZOLAM is Extremely useful for research purposes,pure and effective! But shipping took more time than expected! Hope it will be faster at next order!

Clonazolam appears to be of phenomenal purity and looks and performs exactly as expected in testing.Highly recommended!

I did receive my package a few weeks ago. Scientifically speaking, Diclazepam powder was excellent!!

Flualprazolam….GREAT! Very effective! I will definitely be back!

Finally get my reshipped package!!! wait too long time, but good quality,extremely useful for my research!

Do you reship if seizure at china or US customs? If so what is the total cost of reship? Will you provide tracking number?

it’s a good drug for what it is. Low price and high availability.

I would say your etizolam price is little higher than other vendors , but the quality is good , recommended !

GREAT Etizolam…. Very effective!
