i have mixed feelings on nootropics . even when they do work its mild far from the movie limitless but hopefully we will get there someday , never tried modafinil suppose to be an amphetamine like substance and is illegal now in many places was used by miltary for alertness. noopept never did anything for me , phenibut twice i got drunk off it but all other times i was so dosed i was tired as hell the next morning like i overloaded in melatonin . unifiram i never got anything but real fucking dizzy . never felt anydifferent from alpha gpc . but maybe im a rare instance . so if i was you grab the smallest doses of nootropics to try out before you grab kilos of the shit
