Bodybuilding supplements with potential for high?

[Nicaine]

Bodybuilders use so many freakin' supplements, some of which tend to be relatively unknown to the general public at any given time.

Aside from obvious ones like GHB, steroids and phenibut, are there any little-known (currently legal) bodybuilding products with the potential for euphoria, stimulation, relaxation or a high of one sort or another? Believe me, SWIM doesn't want to blow anyone's cover, he's just interested in what might be out there (particularly newer products that haven't really come to light yet, if any).

Even if it's just euphoric by virtue of increasing blood flow to muscles or rapidly boosting physical health, SWIM is interested... he's always on the lookout for new harm reduction products to add to his arsenal.
