Will taking pituitrophin pmg by standard process help with my friends height? he is 17, 107lbs, 5.7 feet tall. if so, whats is the science behind it?

Questions. Has your friend had a bone age study showing open growth centers. If they are closed, nothing will add height. If open in a person with normal hormone levels even injecting growth hormone only pushes growth to where it would be naturally. These supplements are not pre-screened or regulated by the FDA. They do not need to prove effectiveness. I consider it a waste of money.

No. Likely stopped growing but check with his Dr.
