i had high expectations from reading anecdotal experiences but it's definitely subtle with my neurological profile. i wouldn't say i notice much in terms of memory enhancement but for fine motor coordination it really does the trick for me. i also have found there's an effect similar to motivation but it's more that i just start doing things that need to be done. not motivation in the sense of goal oriented drive.
i'd give nootropics depot 5 stars on their service and this particular product a 3.5 for personal efficacy so i'd interpret my 4 stars as 4.25. i still have most of the bottle left so i might get a better feel for it in the coming weeks. it might also be more potent for other folks.
