Thanks for posting the spreadsheet, Nelson! I have tried many on the list and many that aren't, but my favorite by a long shot is Aniracetam. It has two major upsides that I love - its anxiolytic properties and its ability to open up creative and language fluency channels in the brain. I write music for fun, and I can tell you unequivocally that ideas for melodies and words come almost effortlessly when I take Aniracetam. I believe Dave Asprey, the Bulletproof guy, also raves about Aniracetam and he says he wrote his last book while taking it. I know the racetams work very differently for everyone, but just thought I'd share my experience.
