I think it makes a difference and where Im at they're only 5$ for 100tabsx1200mg each!!
They ban EVERYTHING in my country, so I dunno how Piracetam slipped through that all-encompassing net.
I feel more aware on it, especially if sleep deprived or dieting. But if you feel good already, it may not make a difference.
For a real increase you can feel, in brain power, Vasopressin for memory (used sparingly), or check out Nicergoline. The other Nootropics are decent too, but as with Piracetam, they work best when you need them. If you are already functioning at a high level, rested and well fed, not much difference. People want the effects of the ADHD drugs with Nootropics, but they just don't work that way. And Ritalin, Adderall and the others have a downside. You function at freaky levels of concentration and efficiency for a while...then you crash, can't focus on shit for several days and feel like your soul was removed with a rusty soup spoon. Good times...good times...
