First Endurance has upgraded their high performance Optygen capsules to provide even greater performance benefits. The new formula contains 50% more Beta-Alanine (1.5 grams per serving total) to further increase muscular endurance, boosts strength, and improves exercise capacity. It also features their OptyMax Proprietary Matrix (a blend of herbal ingredients) to help boost endurance. It still contains 67% more Rhodiola than the original Optygen, is designed to help you through your most intense training and racing. The formulation is based on the latest human clinical research. The research has shown the following endurance benefits:

  • Increases Endurance and Performance
  • Reduced Lactic Acid
  • Increases oxygen utilization
  • Increase in VO2 Max
  • Increase in Time to Exhaustion
  • Increase Anaerobic threshold
  • Improved exercise capacity
  • Increase Maximal Oxygen uptake
  • 30% - 50% increase in Oxygen Utilization
  • Increase ratio of ATP by 45% - 55%
  • Increase in ATP production

There is never any hypertension or cramping with Optygen. Because Optygen will help you adapt during times of maximum stress, it also aids in recovery. Optygen should be taken consistently over many months. Using Optygen for just a week before a race will produce minimal results. 30 servings per container (120 capsules. 4 times per day).

Improved recovery time

Used for a couple of years after reading a positive review by a medical professional who was taking it himself. I cannot claim any better performance, but I do believe that my recovery time after intense or endurance events was much improved. Ultimately I stopped taking this as this expense is so high.
