I bought 2 grams in the mail to us in 8 days pure chemicals My mice love it Have ordered here three other times but those chems are discontinued loved flubromazoLAM sad to see it go . and a cathinone I bought would give them all five stars and always generous samples.

Good stealth and fast shipping! I must say the EU38 mixed with the EU36 was a huge success.

Discreet packaging, and very pure product. Was able to achieve 10mg/ml solution in 95% Ethanol with no undissolved trash. Made it to the southern US in 3 weeks. Very satisfied, will order more again soon!

So I have ordered many times, this time i ordered a sample pack of benzos, everthing seems right except i didnt get my extra sample and the bromazolam is pink? with no taste? I have ordered bromazolam in the passed and it was not pink and their is a " R " written on it. Everything else seems great, I havent ordered since laws cchanged in china which made alot of benzos illegal. Other than that this time everything seems right im just questioning that bromazolam or if maybe a different color agent was used to produce it and it came out pink, this i do not know BUT all that aside all seems great, got package pretty fast 13 days, thanks guys , maybe we can have a talk to tell me what this pink "R" labeled stuff which is supposed to be bromazolam. I also have Pink stuff from when china law went in effect and it was Flubroazolam and labeled F3 and has a different taste from the first time i ordered it and it was more white/yellow but this F3 has a taste and the orginqal first time i ever order flubroazolam which is now illegal it tasted like pure ALprazolam and i couldnt believe how that was so im kind of lost here with what exactly I may have ordered that differed in the past to now, Thank you I will continue to buy but please have the guy get it right, i already was sent a incorrect package that was supposed to be a benzo and i paid for it and it is a cannabanoid and we can grow our own cannabis here..... Thank you guys thought for your timely service and maybe we can have a chat so we can clarify a few things so i know whats what, thanks alot for everything

Came to eastcoast in exactly 2 weeks! Top quality of course!

Great customer service as usual. Top notch product, as usual. Nitrazolam came to me as a sample and I was very pleasantly surprised. grade A+.

This kind of material is entrancing to study. Research will make you thirsty, maybe a bit sweaty, and in a nice zone. Careful! It can sneak up, so don't research much at a time , you'll think, at first, it's junk, and ignore it or research twice as much, but this will get you in trouble, give it time, be patient, that is NOT hype, you will see exactly what I mean, it's sneaky and very very very rewarding; trust me, price is misleadingly cheap.

Amazing product, wonderful customer service and super quick shipping- very discreetly & well packaged. Can’t wait to order again! Thanks!

Wonderful service, fantastic quality, quick shipment & great customer service! Thanks!!!

Literally one of the best cannaninoid ever so far, IMO. Be careful, it can be intense, it's extremely good value. For real you should get this if you know anything about this kinda stuff. I PROMISE you won't be disappointed!!! 😉

Little bit late of a review but everything arrived fast to Canada with good stealth and the quality is good

Incredible quality as always! I've been doing research with their Chen's for years now and they have been the most consistent highest quality out of any vendor around!

Dave furuyama exceent product. made another order. the flubro is excelet too cant go wrong with these. can i have a 10% disccount for this review??? you guys are the best!

I agree, this company is the Best by far. Must have amazing people throughout. My go to people, total top end professionals. Thank you for showing how good a company can be operated. #1 from customer service to pkging, to safe speedy delivery to high quality product and people!

Very pure and powerful. Be careful with dosages and volumetric dose with pg solution,

bromazolam id powerful highly reccomended. just be very carefu with dosing

This was my 4th order, as always professional packaged, only 2 weeks to the midwest. Usually get etizolam but wanted to try something new, and testing results was amazing. Definitely gonna order several more grams.🤪

Recieved bulk order amazing quality and company!

Volumetric dose benzo powders

my first time testing this was great i wasnt expecting much from it but but i was wrong iam going to be making a bigger purchase and packaging was great A++

What Can I Say about these amazing Individuals ,AMAZING ASF THE BEST OF THE BEST VERY PROFESSIONAL AND ALL ABOUT QUALITY. LOOK NO FURTHER THAN RC IS THE BEST SELL BIZ EVER.

Nice

I was on the fence about ordering from these guys at first, but was like screw it. It's worth a shot. Boy oh boy am I glad I did! Shipping took a couple weeks but I expected that. Packaged very well to make sure if it doesn't get opened and inspected it should go straight through customs. If they do catch it though you get a free reship! I was actually shocked when I received my order. Extremely well packaged and discreetly as well. I only ordered I think 2g of flualp and clicked on free sample for eutylone twice. Surprisingly enough to me, they sent me the free 2 g ofv eutylone! I haven't tried the flualp yet, but I have high expectations now. I've been trying to keep placing orders through a couple different vendors so I can try to start to stock up on some stuff. So I have flualp pellets right now that I'm using; until I figure out the dosage for this flualp powder. I saw this mentioned in another comment and it's the only thing "bad" I can find to say about my order. This was an order of 2 different little bags of powder. I had zero clue which was which and what was what. The baggie of eutylone had "TY" written on it in black magic marker and the other baggie has "F1" or "Fl" written on it faintly. So I took a a bit of a gamble when I first went to try my products. Other then that, I can't think of anything bad to say so far. This was my first order. I already have a cart filled and ready to place another bigger order once I get paid. My hope is they go above and beyond like I'm reading they're doing for ask these other customers that are leaving reviews.

Is the review above me Justin Mills?Anyways always a great transaction with rcbest been shopping here for years average 9 days to the USA!

The other stims. Was not to good I am not sure the name but will get back with you

Etizalam. Was great!! Quality also something that I would like to offer around my community maybe y'all would send me a sample to try to spread news about

MEP. It was good quality and had a good effect it was something that I feel is something that I can tell my people that is worth buying

RCB Is THE ONLY VENDER I'LL EVER ORDER FROM. Their research compounds are 99+% pure, packaging is great and well-handled, and their prices are unbeatable. My second order arrived to the Eastern US within a week. Awesome job y'all. Keep up the good work!

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 !

Awesome service every time.

Fabulous product. This website is no B.S. GREAT BUSINESS,REAL PRODUCT!!!!!

Everything as expected..great communication and tracking was a dream .. thank you for providing a great service!

Great service on time no complaints here

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

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.

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!

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

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

Wonderful brilliant chemical. Expensive but great!

Only company to be ur supplier. Love them

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~

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

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

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!

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!

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!

excellent research chem for my lab rats, will be back

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!!)

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!

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.

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!

Can’t wait to try products

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!!

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 !!

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

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

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!

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.

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

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

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.

This is amazing! love this offer from RCB!

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

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.

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!
