pre-workout supplements that work work because it contains caffeine. you're better off just drinking some diet soda (to avoid the calories) or drinking some coffee because it's much cheaper. the caffeine in pre-workout supplements is what's giving you that added energy, not the other stuff, but the added energy gives people that biofeedback to make them think all that other stuff is working too (logically speaking, people forget that correlation is not necessarily causation).
