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.

Great products, excellent customer service and fast shipping! I had a broken ampoule in a recent order from shipping and Cosmic Nootropic responded fast with the option to reship the product or in store credit refund. No questions asked. Everything with multiple orders has been excellent service all around.
