What is HMB?


BetaTOR® HMB is the pure, free acid form of HMB (beta-hydroxy-beta-methylbutyrate). HMB is produced naturally in our bodies during the metabolism of the essential amino acid leucine. Studies show that BetaTOR increases strength and power, improves body composition, and aids in recovery from intense training. BetaTOR first prevents muscle breakdown during and after workout and increases muscle synthesis (growth) in the recovery phase. Clinical research has shown that supplementing with BetaTOR during an intense training cycle can improve strength, power, body composition, aerobic performance, and recovery.

Increase Your Performance*

► Improves recovery by reducing exercise-induced muscle damage

► Increases anaerobic capacity and endurance

► Improves performance and body composition response to exercise

► Imptove strength and reduces muscle soreness

For optimal benefit when training, consume one of your servings of Cowbell Recovery 30 minutes prior to exercise. This allows for increased peak levels of HMB FA in the blood prior to training, which results in improved efficacy and recovery.


HMB is one of the most researched supplement ingredients proven to improve athletic performance right behind Creatine Monohydrate

HMB works better in athletes who regularly get sore. The published studies on HMB have training protocols that often involve movements like squats, deadlifts, sprints, presses and interval sprints on rowers and bikes.


HMB works across different training models. In study after study, HMB has been shown to improve your performance in the training you are doing. Strength athletes increase strength, endurance athletes improve VO2 max, for example


Published human research studies back it. HMB has a large body of research on athletes training in various modals, similar to those of CrossFit movements. How do you know if a supplement works? Test it out on athletes doing the same training as you!


HMB works extremely well in master's athletes. A study found that as we get older, the amount of HMB we have in our body decreases. Taking HMB regularly is also shown to slow muscle wasting as we age. For Masters athletes, the natural age-related decline in musculature is obviously not something the doctor (or coach) ordered. HMB could be a great supplement for this ever increasing CrossFit athlete population.


HMB helps speed recovery from injury. HMB has an anti-catabolic effect, meaning it slows muscle breakdown in conditions like inactivity and bed rest. For the injured athlete, this means that taking HMB may be a great way to slow the muscle wastage due to inactivity. Get your hands on some HMB for the next time you get that wrist strain from heavy cleans.
