PEAK ATP® maintained force output and tended to reduce muscle fatigue during exhaustive exercise.

A double-blind, placebo-controlled, human crossover study assessed the muscle performance-enhancing effects of 400 mg of PEAK ATP® (200 mg twice daily) on healthy, active adults. Sixteen male and female participants were randomized to receive either PEAK ATP® or placebo for 15 days. Before and after each supplementation period, each participant completed a muscle strength and fatigue test consisting of three sets of 50 maximal knee extensions. After a one-week washout period, the groups were switched, so that those who had been taking placebo now took PEAK ATP® and vice versa. PEAK ATP® improved participants’ ability to maintain force output during an exhaustive exercise bout and tended to reduce muscle fatigue.
