Several important points make the product, Extreme Endurance, a compelling story. First, this product is based on science.
Extreme Endurance (xendurance as known in the EU) is the only product in the world that has a Gold-Standard, third party, double-blind, placebo-controlled, crossover study – that has been published. We emphasize third party because it means that we, at Lifespan International, did not know who was testing the product. Many companies pay other companies to “hopefully” get good results – we hired a company to test Extreme Endurance that had no knowledge of Lifespan International or the product – and the results were off the charts with a 15% reduction in lactic acid and a double digit increase in aerobic threshold.
