Optygen is a legal, safe and stimulant-free formula designed specifically to optimize performance for endurance athletes. WADA, USADA compliant. This revolutionary formula is based on human clinical trials and the latest scientific research on increasing endurance. - The two main adaptogens in Optygen were first used by Tibetan Sherpas to help them climb Mount Everest. Optygen utilizes these unique adaptogens because clinical research (on elite endurance athletes) has shown them to increase oxygen utilization. This increases the body's ability to adapt to high levels of physical stress, increase anaerobic threshold and reduce lactic acid.
