What we think

First Endurance names this "the ultimate endurance supplement." Why? The OptygenHP is the new and improved Optygen formula and features their exclusive OptyMax Proprietary Matrix. Clinical research on elite endurance athletes shows an increase in VO2max, an increase in the body’s ability to adapt to high levels of physical stress, an increase in anaerobic threshold, and a reduction in lactic acid. These studies showed:

  • A 26% decrease in cortisol levels
  • A 42% increase in time to lactate threshold,
  • A significant improvement in endurance capacity
  • A significant increase in energy (ATP) production.

Athletes who participated in these studies were able to replenish glycogen faster, which leads to improved recovery and improved performance on back-to-back workouts and during heavy training. In addition, subjects experienced less muscle inflammation after high-intensity exercise, resulting in less soreness and faster recovery. The main adaptogens in Optygen HP were first used by Tibetan Sherpas to help them climb Mt. Everest, so we know they’ve been working their craft for a long time.

How We Use It

We take 4 capsules daily with a meal. Daily use promotes increased athletic performance and faster recovery. These will not work if you just take them a few days leading up to an event. To receive their full benefit, long-term use (greater than one month) is recommended.

This product seems to do what it claims to do. I've been on it for about 3 weeks now. I've been in heaving marathon training for about 4 months now at 70 miles per week. Since being a Optygen, my heart rate seems lower, I'm able to push harder on my track workouts, and perceived effort is definitely lower. I love it! I'm looking forward to taking it for longer and see how my body responds. Definitely recommend Optygen!

The only product I have tried that does something. All 1st Endurance products are great. Also like Utragen and EFS

Keaton V.

I bought it for my brother. He is very happy with this product. He already recommended it to me.

Jennifer S.

I'm really happy with the results I've gotten using OptygenHP especially when combined with HVMN Keton Ester. To all the low rearing complaint about the cost shift seems to me like you guy think this is normal optygen, it's not this is a new formula. The original optygen is still available threw frost endurance at the low price point y'all are used to.
