I'm in for the ride.
My personal favorite and a staple of mine is Aniracetam. I have yet to find anything that works better for anxiety and public speaking. This stuff is simply amazing to me and 30 min after taking it, my head just clears up and words are so easy to find when talking. I can't imagine being without it.
Piracetam- I hated it. I played with the doses and could never get it right. It made me tired, irritable, slow, and was bad for public speaking. Maybe it would be good for studying, where you don't have to interact with people, but it did not sit well with me. I tried adjusting choline levels too.
Oxiracetam- I liked it, but was very similar to huperzine-a to me with the mental energy and if you take too much, the anxiety. It is good stuff, but expensive, when I could get huperzine for a 1/3 of the price and essentially have the same effects.
I look forward to you review on noopept because there are mixed ones out there. That is part of the experimental part of noots- everyone reacts differently.
