CreaLean 100% Creatine Monohydrate contains only pure creatine monohydrate. Research shows that daily oral administration of creatine monohydrate increases muscle stores of creatine, resulting in lean body mass gains. Creatine supplementation may also increase muscle torque production, support healthy levels of plasma ammonia, and aid muscle fiber in maintaining a high phosphocreatine level, resulting in the ability to sustain higher workout intensity levels for longer periods of time.
