Basically this is like using steroids to increase muscle mass. These drugs can have serious side effects, particularly in young men who have normal levels of these hormones already. They can also cause significant problems in women, including masculinization and abnormal (male-like) hair growth, as well as disturbances in the normal cycle. Excess testosterone may cause liver damage, increases the risk for blood clots, and may result in breast tissue growth in men. It can also affect the testicles adversely. Too much HGH can cause excessive growth of soft tissue in the hands and feet, and ugly changes in the facial structure that may be permanent. All in all, you would be much safer not using these hormones. Hope this helps.
