During intense training, don't just "hit the wall" with muscle burn and pain - blast through it with Xendurance, a revolutionary athletic performance formula. It's clinically proven to reduce lactic acid by 15% and increase aerobic threshold by double digits.
Xendurance is a revolutionary athletic performance formula created by athletes for athletes. This formula has a Published, Gold-Standard, third party, double-blind, placebo-controlled, crossover study backing up claims of 15% reduction in lactic acid and a double digit increase in aerobic threshold. Many companies make claims on individual ingredients but Extreme Endurance has a published study on the formula itself. Each batch of Extreme Endurance is tested to ensure that it is not contaminated with banned substances to provide additional reassurance for elite athletes.
Xendurance is able to safely buffer the hydrogen ions (H+) acid in lactic acid with powerful buffers. In addition, Extreme Endurance adds second generation ingredients to its formula to address other biochemical changes that occur to an athlete's body during intense exercise, such as tissue damage, oxidative stress, suppression of the immune system and harmful inflammation. These added ingredients are:
Papain, a protease enzyme derived from Papaya, which is a powerful anti-inflammatory that helps repair and rebuild muscle tissue and relieves muscle soreness.
Catechins are added and are one of the most powerful antioxidants to help fight oxidative stress during exercise.
Electrolytes complete this revolutionary formula to assist athletes with the ability to quickly recover and restore balance and maintain the competitive edge.
