I don't know why Mooney has such a hard-on about Serono when there are many other GH manufacturers, like Pharmacia, Genentech, etc. Maybe it's because they're specifically marketing their product for "off label" use. Anyway, i think there's something going on with GH and these pharmaceutical co's. because someone is making a lot of money.
I don't think anyone really has a complete understanding of GH and how it exerts its anabolic effects, if any. I do know from personal experience that it does work as a metabolic regulator; and it takes far less GH combined with anabolics than by itself to exert a definite effect. But that doesn't explain how GH develops the musculature in infants and children. There's got to be something there besides raw levels that we just haven't figured out.
