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.

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!
