Muscle building. Amplitude takes building lean muscle mass in a new direction by augmenting body composition with its pro-anabolic non-hormonal adaptogenic formula. When an internal or external stressor is present, Amplitude helps overcome its imposed demand by amplifying the rate at which the body adapts, returning it to a state of balance faster. This means athletes can experience enhanced performance levels, shortened recovery times, and improved rates of muscle growth when exposed to stressors like resistance training.
