MDA takes longer to hit (over an hour sometimes), lasts 2 times longer than MDMA (3-5 hrs), more of a speedy trip accompanied by budy buzzes and some visuals. You also don't get sa friendly or lovey on MDA, sort of just full of energy and kinda frustrated at the end. Def. more of a club drug than MDMA. Ahhh... had some crumbled benzes last week, def MDA..not a fan.
