Mutant ZMA+ contains proven levels of zinc, magnesium and B6 that were shown to increase anabolic hormone levels in athletes; researchers reported that athletes taking those 3 nutrients experienced more than a 30-percent increase in testosterone levels, and about a 5-percent increase in levels of insulin-like growth factor 1 (IGF-1). Plus we've added the patented absorption agent BioPerine® at its manufacturer-prescribed full 5 mg dose, making MUTANT ZMA+ a stand out formula in its class.
