It’s Sherpa-tested. There’s no way you can go wrong.

OptygenHP by 1st Endurance isn’t for everyone. You won’t need it to walk your dog or speed walk around the shopping mall. But if you’re a marathoner, triathlete or elite endurance athlete, that’s another story.
 
The two main adaptogens in OptygenHP (Rhodiola and Cordyceps CS-4) were first used by Tibetan Sherpas to help them climb Mt. Everest. OptygenHP also contains Beta-Alanine because clinical research shows it increases exercise capacity and muscular strength.*
 
What can OptygenHP do for you?
- Increase your VO2 Max*
- Helps you better adapt to high levels of physical stress*
- Increase your anaerobic threshold*
- Reduce lactic acid*
 
Give OptygenHP a try when you’re training for your next race.
