Anybody have much experience with the racetams? Let us know which ones you've tried, how they affected you, whether you took a choline source, and whether you'd take them again. I'll start. Piracetam: took on-and-off for about two years, in dosages ranging from 400 mg 1x/day to 2000 mg 3x/day. The smaller doses gave me a slight increase in thought-speed. The larger doses made me want to sleep. Never seemed to matter whether I took a choline source or not. I mainly got really interested in math and coding, but not at the expense of more associative thought. Will definitely do again. So subtle that you won't notice if you stop taking them until a few months later when you wonder why relational databases seem so boring now. Aniracetam: took 750 mg once or twice per day for about a month. Highly anxiolytic, made me kind of tired, not much else. Don't think I'll try them again. Oxiracetam: took 200 mg two to three times per day. Definitely the most stimulating racetam for me (even more so than phenylpiracetam). Made colors brighter, sounds sharper, and reflexes faster. I got so fast and accurate at drums it was kinda ridiculous. After a while, I developed a very disconcerting tic in my neck and temple, which went away when I didn't take it. Definitely felt kind of edgy if I had too much. Tasted chemically sweet--you could put it in your coffee if you wanted. Will try again in the future, but not a priority at the moment. Phenylpiracetam: just ran out of this. The first few times I took it (extremely small dose, like 10 mg), I was so amped up, I felt like a teenager ready to go vaguely wild. Then the next few times, it made me feel sleepy, overwhelmingly so, to the point where I had to take a nap. Eventually just felt more or less like regular old piracetam in terms of getting more in touch with the analytical/numerical side of my personality. Weirdly enough, the microdoses seemed most energy-inducing. Due to the cost, I'll probably wait a while to try this again, since I can get the same effects from piracetam. Not sure what I want to try now. It's between coluracetam (super-expensive, apparently), pramiracetam (horrible tasting I hear, even for a racetam), and sunifiram (not a racetam, but similar). I've experimented with various choline sources (DMAE, choline, acetyl-l-carnitine) with all of the racetams. I've never had a headache from any racetam, but I do easily get headaches and muscle tension from choline itself, especially regular old choline bitartrate. Aceytl-l-carnitine combined with alpha-lipoic acid is my favorite, as it gives me a little bit of physical energy and a slightly clearer head.
