It really comes down to what you are trying to accomplish. We know noots affect people differently, but there are generalities that are pretty well supported.Pramiracetam was too edgy and speedy for me and bothered my tendency towards anxiety. It was focused, but not the way I desired because it took effort to stop a task and then refocus on a new one. Thoughts didn't flow from thing to thing. It would be great for a project that didn't require interference and social interaction, IMO. I found that Piracetam and Pramiracetam would be ideal for a college student cramming for exams. I take Aniracetam and AGPC M-F.
