"Once HGH is released, it is very short lived. It is generally metabolized and gone within a half-hour. During this half-hour, it travels to the " href="http://www.ar-r .com/">Growth Factor One (IGF-1)."

"Injectible HGH is completely absorbed and put to use within approximately 3 hours."




My question is about the two quotes above.....Does the exogenous HGH stay active longer than the endogenous HGH?
