I've noticed a lot of people using this stuff. Does it really do what they say it does? And if this is true, wouldn't you loose size after you stop taking it, or does it help with permanent hypertrophy? Also another question. Does anyone know the real world effectiveness on ZMA? I've already read one study on it that seemed pretty unbiased and they said there were no significant gains but if you look at the data those as opposed to placebo did gain more strength and loose body fat.
