HCG is used to increase sperm production and raise natural testosterone production levels
Male bodybuilders use hCG at the end of an anabolic-androgenic steroid cycle to prevent the breakdown of muscle tissue and to restore the testes to normal abilities. This often returns shrunken testes to their normal size. When used along with a very low-calorie diet, bodybuilders burn off that extra layer of fat over their muscles, giving them an extremely defined look. Females may also use hCG with a very low-calorie diet to burn off unwanted fat.
