IGF-1

Ran across an article on IGF-1 that stated while it builds muscle,it doesn't build the surrounding connective tissue,blood vessels,or cell energy centers,which makes the muscles work abnormally. Doesn't sound like a very promising athletic anabolic supplement by this account. Any thought on this???

that's why you should use it with GH... Although I've never hear that statement about it before...
