I didn't deliberately set out to find it, really. I'm also not quite sure how well it works yet. The effects are supposed to be cumulative, meaning the longer you have been taking it, the more of a confident jerk you become, and you continue being a confident jerk even after coming off of it (maybe). I doubt it's that much of a game changer really, it's a pretty commonly used nootropic and not many people list improved confidence as one of the effects--perhaps because the effects are subtle and only come with continued usage, or perhaps because they simply aren't very strong effects to begin with. It might be useful for people who have chronic social awkwardness though.

(if anyone reading this ever sees me act like a confident jerk, please tell me)
