As an athlete you already know the harder you exercise and compete, the more acid builds up in your muscles. Both your blood and muscle pH goes down into the dreaded acid zone. The increased use of muscle glycogen for energy produces lactic and pyruvic acid. Acidity reduces muscle power and reduces physical and mental endurance. You, your trainers and your coaches refer to this as lactic acid buildup or lactic acid fatigue. On the practice and playing field, it is also called "hitting the wall" or having the "bear jump on your back". It's simple. The harder you compete, the quicker you Go Acid! The Athlete who "Goes Acid" last, wins the competition.

XENDURANCE - Athletic Performance Formula that Reduces Lactic Acid and Increases Aerobic Threshold.

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 increase aerobic threshold and reduce lactic acid.
All ingredients are in compliance for IOC, NCAA, NFL, NBA, NHL and MLB.

Tested for Banned Substances

Xendurance (Extreme Endurance) is tested by the largest sports lab in the world. HFL Sport Science is located in the UK and its testing of Xendurance is done using gaschromatography with mass spectrometric detection (GCMS) and liquid chromatography with mass spectrometric detection (LCMS). In layman?s terms, - if you put one drop of a banned substance in an olympic size swimming pool, this testing would find it. It is costly, but we have many pros who can not afford to have their tests come up positive. HFL?s newest testing programs for athletes are called Informed Choice (US) and Informed Sports (EU).
