Fastest delivery yet. Product is exactly as described. Thank you for your service.
Excellent research chemical quality. Very reliable vendor. Excellent customer service.
Rcb hands down the best true to their word and great customer service with like they say basically pure quality 99% but highsuspekt it would be cool if u got a gm/ms machine but do you know how expensive try are?!? Very so it would make bad business sense to give those with your order ya know but if they somehow could it’d be awesome for sure!!! But ya love RCB always my permanent supplier fs
Waiting on restock but hoping it’s sooner then later and hoping it’s the better clam
Customer service is pretty great, however a downside: New white c-azolam seems 30% less potent than the yellow varietal, though this may be a batch issue. The same is true of F-alp. On the other hand, while the order did not ship initially, they made it right by resending, even after 3 months!
This one works pretty good but I need 5c ladba to restock or adb-4en-pinaca to really have what I need.
Hey Luke, can you tell me how you were dosing the flualp powder
The other stims. Was not to good I am not sure the name but will get back with you
Clonazolam came fast and very potent. Cant wait to order again!
Excellent product, excellent timing as well. My package arrived awesomely early. Keep it up!
Superb 2f dck. The best quality from any vendor since it was on the market. Still not as potent as DCK. But DCK is too strong for some people. This was perfect for the price. Looked exactly like the picture. Ordered months ago, although the order did come quickly. I wish they had more in stock.
Waiting on my order for my lab, it should be here tomorrow! I will report back on quality, shipping time etc… But I expect good things from what I hear! Also they have a great team who will address your any questions within 12 hrs they are top notch so far….we will see….
Made it in record timing!!! 13 days to east coast, USA!!! Great products every time!! Will no longer use any other vendors for research, due to the purity almost always being ≥99.4% !!! RCB is our “go-to” provider for all research needs for our small research group !! Keep up the great service, YOU GUYS ARE WONDERFUL !!!! THANKS AGAIN RCB !
Fabulous product. This website is no B.S. GREAT BUSINESS,REAL PRODUCT!!!!!
Very fast delivery Honest Company everything that’s going on they’re still on top of their game
Everything as expected..great communication and tracking was a dream .. thank you for providing a great service!
4th or 5th order came in stuck in customs but they reshipped and it showed up incredible fast. Product is always exactly as described.
Also waiting on large restock .As the above user says its in extremely high demand !
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.
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 😀
Research shows this chem to be an effective stim. Similar to hexen. But dare i say better?
repeat customer – reliable shipping, quality product, good communication… thanks.
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.
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.
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
very pure substance, good-value, shipped relatively fast and stealthy. Overall, 5/5
great vendor, top notch quality for research, never failed delivery! Long time customer
2 weeks and I got it. Very potent and good quality. Awesome stealth also.
grade A. thank you for helping further scientific research.
After almost a month and a half, it showed up. Surprised and amazed at the quality
Hi friend, I did receive my package. Scientifically speaking, 5femb2201 was excellent
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
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
This product is in high demand everywhere. Waiting patiently for a big restock.
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.
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

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.
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 !!
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!
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!
I’m glad back in business. Looking forward to receive first order. Great customer service
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
This is the best high grade research chemicals right now.
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!!)
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.
5/5 my friend. Message me. Hey this is crystallized and I’m fact worth it.
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
Order once again came in 2 weeks I feel this time the etiz is more potent
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.
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!
Quality product. You get exactly what is advertised and the communication and shipping went seamlessly.
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.
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 !!
Excellent quality, mine initially was stopped but the reshipment came quickly and easily. RCB is the best!
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!!
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!
Researched a sample, will definetly be buying a Batch for my next experiment. Thanks!
Excellent stealth, product quality is on point. Was my first order and will certainly not be my last
Quality product, my research shows this is like a more potent 3-fpm,smooth long lasting functional stimulation
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.
Took a week and a half to arrive,very good product no issues at all,great vendors.
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!
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+
Quality 10/10 – shipping was a bit odd, but fine. overall 10/10
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.
This etiz is the shiz love looking at it under a microscope as well as testing its purity
THE FREE a sample proved POTENT. Keep the lab equipment safe abd unplugged once in awhile this stuff is nooo joke. 5 stars!!
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
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!
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.
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!

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!!!

Fast service. Super discreet. Good comms and the quality is superb. Thank you guys.
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.
This is an extremly good product that is easy to order and a good ptice
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.
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!!
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
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!
GREAT SERVICE, EXCELLENT AND FRIENDLY STAFF. NO BETTER IN THE BIZ FOR SURE.
This came rather quickly considering it was from China, but it was well worth it. The Clonazolam is top knotch.
Perfect product. Is what it is supposed to be, and fair priced at that! Will certainly be back!
10/10, that’s all I really have to say. RCBestSell is probably the biggest reliable vendor out there.
Very pure stuff by mass spec confirmation! Couldn’t be happier! Also, very discreet shipping.
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.
Was so shocked made my feet drop, when test the purity of this. Fast delivery and by far best Legal RC Company
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!
The etizolma was as pure as I have found. This company truly delivers what is stated. Will always use their compounds for our research!
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
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!
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!!
Finally get my reshipped package!!! wait too long time, but good quality,extremely useful for my research!
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 !
