HMB plays a role in the synthesis of muscle tissue. It has the ability to burn fat and build muscle consistently in response to exercise. Backed heavily by science, HMB works for NFL greats like Shannon Sharpe and Olympic medallists throughout the globe. New scientific studies are being conducted on this supplement all the time. Recently, a study showed in a control group supplementing with HMB, that after taking 3 grams of HMB per day for three weeks, those who took HMB versus the random placebo takers gained three times more muscle on their bench press! Animal studies also suggest that it may increase lean muscle mass.
