Nootropics (smart drugs) were all the rage a few years ago - they were opening entire store-front operations where you would sit down and for only $25 receive a "smart" drink that was supposed to turn you into Einstein for a few hours.
The only smart people that came out of these places were the ones selling that junk.
But if you have a few hundred bucks to burn, why not try some and see what it does? AlphaZXT is mainly just a few plant-based derivatives, so fairly safe.
