I am currently running hmb at 3g per day in either eas reload or armor, I started taking it for basically wound healing, since that is what we use it for at the hospital, in the form of juven. I believe that it has accelerated the healing of a nagging lower ab injury that wouldnt improve for months. I have been taking the HMB for roughly a month 1/2, improvement is vast! As for performance increases, cant really say much.
