More details

EXTREME ENDURANCE 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 26% 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.*


Extreme Endurance is tested by the largest sports lab in the world, LGC. If you put one drop of a banned substance in an olympic size swimming pool, LGC's testing would find it. This is costly, but we have many professional athletes who can not afford to have their tests come up positive. LGC's programs INFORMED-CHOICE and INFORMED-SPORT certify products free of banned substances.

Why is testing in sports nutrition important?

Every athlete should know about proper pH balance. PH balance is critical to top athletic performance. PH is measured on a 14 point scale, 7 being neutral. The arterial blood pH value of a healthy human ranges around 7.35 to 7.45, which is slightly alkaline. As our body uses fuel and metabolizes food, we produce acid waste.

Your body's acid concentration increases as you produce lactic acid. Lactic Acid is not good, especially when the acid concentration exceeds the body's ability to neutralize or flush the waste from your body.
