Are lots of people starting to take it.
From what I understand growth hormones are produced by the pituitary gland. I have a friend who is diagnosed as a pituitary dwarf and he took daily injections when he was young. If you are looking to bulk up your muscles then steroids are the most unhealthy and unstable substances you can use. Many Many negitive side affects. There are natural anabols that stimulate muscle increase but are still hard on your system with prolonged use. The best way to increase muscle mass is a simple anarobic weight program, simple and effective but plenty painfull. No pain no gain. If interested drop me a line.
Do you mean Human Growth Hormone (HGH)?
