Make sure you use cholin or lecithin w/ it @ about 3 grams/ day, I take about 5 grams piracetam & 3 grams lecithin a day. if you can get your hands on a book called mind food & smart pills by ross pelton, it describes lab results and test from several nootropics, some of the findings are pretty remarkable. I won't say that I have experience that dramatic results in recall ect.., but I can definately notice a difference in remember peoples names, facts, and the ability to concentrate for longer peroids of time.
