If you are serious about reaching a healthy old age, find a doctor who understands
HGH therapy. (You may wish to contact the American College
for the Advancement of Medicine at 800-532-3688 for a referral.) You will have to take a shot of HGH, similar to an insulin injection, four days a week. Once you have stabilized, they can teach you how to give yourself the shot.
What I can tell you is to stop running! I used to run and now have both knees totally replaced.
