This randomized, double-blind, placebo-controlled study tested the effects of EAS Muscle Armor® (main ingredients HMB, arginine and glutamine) in resistance-training men in a 12 week study.  This study showed that supplementation with Muscle Armor® improved the effects of the training on improving body composition and increasing fat loss compared with placebo supplementation. Muscle Armor® beneficially improved hormonal markers associated with intense resistance exercise and improvement in body composition.  Muscle Armor® also resulted in greater increases in strength, power, thigh circumference, and decreased indicators of muscle damage.
