HCG Pregnyl is popular among bodybuilders and athletes to be used at the end of an anabolic-androgenic steroid cycle to prevent the breakdown of muscle tissue. It is also important in restoring the testes to the normal abilities because many times after a period of anabolic steroids usage the testes of an athlete may shrink. Pregnyl HCG is effective in returning them to normal size. When used along with a very low-calorie diet, athletes burn off that extra fat over their muscle mass. Females may also use Pregnyl with a very low calorie diet to burn off unnecessary fat.
