It’s easy to dismiss most supplements as marginally effective at best. But OptygenHP from First Endurance really has an impressive impact on endurance and performance for top athletes. Adaptogens help the body adapt to stress hormones like cortisol for better recovery, while each serving provides 1,500mg of Beta-Alanine, which boosts exercise capacity. The result is a supplement that boosts ATP production for more energy, while increasing both VO2 max and time to exhaustion. For athletes at the top of their form, this can be a real differentiator. And trust us when we say the results are real and noticeable.
