Improved First Endurance OptygenHP is now available in its most potent form yet, containing Rhodiola that's twice as strong as the original formula. It also contains Beta-Alanine to increase exercise capacity and muscular strength. The two main ingredients 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. 120 capsules. (30 day supply.)
