Because glutimine can not be absorbed orally. It is completely inneffective -- total marketing hype. It does nothing.
ZMA is overpriced zinc that you can get for $4 in any drug store. If you MUST have the asperate version, you might as well by "POST-CYCLE" from Protein Factory and you'll get 100% of the daily dose as zinc aspertate along with over 10 other essentially ingredients for less than the price of a bottle of ZMA.
