New and improved OptygenHP formula is now available in its most potent form yet. It contains Rhodiola that's twice as strong as the original formula. OptygenHP also contains Beta-Alanine because clinical research has shown it increases exercise capacity and muscular strength. The two main adaptogens in OptygenHP (Rhodiola and Cordyceps CS-4) were first used by Tibetan Sherpas to help them climb Mt. Everest. OptygenHP utilizes these two unique adaptogens because clinical research on elite endurance athletes has shown them to improve performance, increase the body's ability to adapt to high levels of physical stress, increase aerobic threshold and reduce lactic acid. Endorsed by multiple grand tour winner Alberto Contador. Return to Top
