Do you mean Piracetam?? (Nootropil) ?? If so then its kind of a brain stimulant... supossed to help with memory and concentration...esp. when used with hyderine... I think you should take extra choline while using it... its does not make you tired but actually a little hyper.... I think Rotty may be thinking of Ketofin..which is in his clen which does make you groggy
