BetaTOR is the pure, free acid form of HMB (beta-hydroxy-beta-methylbutyrate).  HMB is produced naturally in the human body during the metabolism of the essential amino acid leucine.

BetaTOR works by increasing muscle protein gains during training through two mechanisms:  BetaTOR decreases muscle protein breakdown through the ubiquitin-proteasome proteolytic pathway while also increasing muscle protein synthesis through the mTOR pathway. 

As a result, clinical studies have shown BetaTOR combined with an intense training program increases strength, power, and endurance; improves body composition; and aids in recovery when compared with placebo supplementation.
