I would assume it would work better, as phenyethlamine is quickly metabilized (or something). I really don't know much, but there is a thread in ADD about this. I'd post a link but I'm in a hurry, shouldn't be to hard for you to find.
I don't think this would be a good idea....if you want it to hit you quicker, empty the 500 mg capsule into your mouth on an empty stomach and wash it down with some black coffee.
well, it would bypass monoamine enzymes and i imagine it would have amphetamine-stimulant like effects, but i'm not sure. injecting the stuff doesn't sound like a good idea to me, and i've shot some stupid shit.
