See the NEW! 2010 First Endurance Optygen HP (formerly referred to and tested as a Prototype version). We no longer carry the older version.



First Endurance
continues to lead the endurance nutrition category by introducing OptygenHP, the next-generation of Optygen. This revolutionary formula is the result of human clinical trials and the latest scientific research on increasing endurance and performance. New features include Beta-Alanine as well the most potent Rhodiola available. The two main adaptogens in OptygenHP were first used by Tibetan Sherpas to help them climb Mt. Everest. Optygen and Optygen HP utilize these two unique adaptogens because clinical research on elite endurance athletes has shown them to:
  • Increase oxygen utilization (1)
  • Increase the body's ability to adapt to high levels of physical stress (1)
  • Increase aerobic threshold and reduce lactic acid (2)
