My Doc believes based on his experience with hundreds of patients that HGH improves the entire metabolic system, literally turning back the clock. It causes the body to better utilize what the person feeds and supplements it.
Many conditions are so improved that prescribed medication is no longer necessary. One example is statins for cholesterol control. All of this is confirmed with blood testing. I'd like to think that low cholesterol is a positive condition for the heart even if it doesn't make it younger.
This improvement is dependant on continuing HGH because the original condition was lack of it. I've accepted the fact that I'm going to be on it long term. Same with the other HRT products. I see them like a vitamine now until something better comes along.
I'm not sure if looking at high profile people like Arnold, Nick Nolety, Sergio and others is a real test of hgh's long term value. Seems like something else is going on with these guys that is aging them strangely.
