f 1st Endurance Optygen Reviews and Information


The two main adaptogens in Optygen were first used by Tibetan Sherpas to help them climb Mount Everest. Optygen utilizes these unique adaptogens because clinical research (on elite endurance athletes) has shown them to increase oxygen utilization. This increases the body’s ability to adapt to high levels of physical stress, increase anaerobic threshold and reduce lactic acid.

Not as impressive as the claim
by Barry

While I agree in the premise that increased oxygen levels do indeed help endurance athletes, endurance athletes typically benefit from that which promotes aerobic not anaerobic training.
I had an opportunity to try this but passed it up because the claims contradict themselves. Plus enough clinical research was simply not available to back their claims. If you want increased endurance, try a slow releasing carb supplement and B vitamins product (liquid) to use during your workouts.
