Faction Labs ZMA is the perfect combination of Zinc, Magnesium and Vitamin B6. Backed by clinical research, ZMA is an effective supplement for enhancing muscle recovery, boosting muscle size and strength, and even aiding fat loss.
Research suggests that ZMA has significant anabolic benefits. A study performed at Western Washington University had NCAA football players take ZMA or a placebo every night during an 8-week training program. It’s reported athletes taking ZMA experienced more than a 30% increase in testosterone levels and a 5% increase in levels of the insulin-like growth factor 1 (IGF-1). Those taking a placebo had a 10% decrease in testosterone levels and a greater than 20% decrease in levels of IGF-1.
