Excellent nootropics supplier !
I've tried many of their products and always had a fantastic experience, Semax, Phenotropil, Noopept and Vinpotropile and all of them works perfectly well and are a must try to any nootropics connoisseur!

Phenibut - Did not work
I have used Phenibut in the past with excellent results and was able to sleep through the night. Unfortunately, this formulation didn’t work, even at a higher dose. It was more than twice the price, which I was willing to pay if it worked. Very disappointed.

I really only stay coming back because I can continuously get Phenibut. But how come I can only get 3 packs at a time?

They send a survey promising a $50 credit for well thought out answers. I took 20 minutes answering it, and they refuse to give me my $50 credit. Do not trust them, plus the supllements they sell can be purchased for pennies on the dollar if you research them. Liars.
