I bought an item called Phenylpiracetam from them, and it didn't do anything for me. It also does not have a favorable taste, and I couldn't stomach trying more than the recommended dose to see if I just hadn't taken enough. At that point, I was skeptical, but went on to try another of their product called Phenibut. A lot easier on the taste buds, and it worked great. Their product is legit. They also worked out the Phenylpiracetam ordeal with me, and were more than fair. I'm 100% satisfied, and recommend buying from these guys 100%. The most pleasurable experience I've had so far in an unsatisfying purchase. Will definitely be buying from them again.
