I came across this book years ago, started experimenting with the nootropics promoted in this book around the same time. I didn't experience the same benefits as other reviews I've read, the effects were much more subtle for me. I would recommend this book but only has a first step to educate yourself in mind enhancing supplements. There's a lot of good info online as well, wikipedia for one. I would recommend Aniracetam Powder Bulk 30 Grams over piracetam by itself, which did cause more of an effect in me than others. Although i wouldn't discount the cognitive benefits of piracetam which I should of taken choline with but didn't at the time. Another book I'd suggest for further reading material on the subject is Smart Drugs II (Smart Drug Series, V. 2). Also a bit outdated but covers details that this book deosn't, and vice versa.
