Guess what? ZMA does boost T, but
ONLY if you're exercising really heavy. The latest suff I've seen about it suggest, that ZMA, produces the highest elevations of T when one is doing heavy compound lifts, like the dead-lift and squat.
ZMA seems to be less effective at raising T when one engages in a "fitness" routine, and practically no elevation at all when one is sedentary. So, spend your money on ZMA
ONLY if you're truly a bodybuilder who exercises really heavy. Now Iknow it truly is for me!
