Imagine a product that could eradicate muscle fatigue in just minutes. Allow you to train substantially harder and recover exponentially faster. Maximize your training efficiency while significantly boosting strength, endurance and overall athletic performance. Sound too good to be true? Definitely. At least without failing a drug test. Now what if I told you it's neither a drug nor illegal. Impossible? First let's backup. One of (if not the) biggest limiters in athletic performance is elevated core temperature. Exertion causes muscle cells to heat up. Via a process called arteriovenous anastomoses, the body does its best to dissipate this extra heat. But if you continue to push yourself, core temperature will continue to rise, compromising the effectiveness of a heat sensitive enzyme crucial for energy production called pyruvate kinase. The result? Weakness, fatigue and cramping. If one could prevent the escalation of core temperature, it reasons that one could extend energy production and delay fatigue. The
