I've read that all racetams, and noopept, can take days/weeks to start building up their effects. I'm guessing this may be why I haven't noticed any changes after using aniracetam, oxiracetam, noopept, phenylpiracetam and pramiracetam acutely.
1) Does this build-up period require strict controlled dosing? For example, I might stop for a day or two, or use a different racetam. Not quite sure how it works.
2) Since I'm running out, I just want to know if each racetam actually affects me. Couldn't I just take a large dose to find out?
