Ive dabbled with lots of Nootropics including Piracetam some people swear by it others dont get much from it
i believe you need to take it with a choline source to get the most of it-- the cholines like a brain energy source-- alpha GPC is the best choline source as it crosses the blood/brain barrier
i can supply you plenty of sources for piracetam even pharmaceutical grade
i bought this not that long ago:
All-in-one Nootropic Mix the best Cognitive Enhancer
i basically figured i would do a shock and awe and decide whether 'Noots' were any good
they did make me feel mentally clear and motivated to accomplish things-- however at the time i wasnt revising or really using my brain much so put the 'mission' on hold until such time i was.
i can also recommend this:
Zoned tablets from Myprotein
these work well contains ginko bilboa 'Rocky balboa?' feel really motivated and my head clear on them
i would recommend starting with that first
