Human chormonic gonadotropin is used during courses of steroids to prevent testicular atrophy and inhibition of total testosterone.
Human chorionic gonadotropin is a hormone found only in pregnant women's placenta. Women have no significant role, but the athlete has some very interesting features. Can imitate luteinizing hormone (HL), secreted by the pituitary gland being the one who gives the signal testosterone. Sex hormones act by a negative feedback when they are present in too large quantities (such as androgenic steroids or estrogen) to send a signal to the brain to stop the secretion of HL. During steroid cycles that stretch over long periods if their own testosterone production is too long suppressed, the testicles will begin to atrophy to the loses functionality. By administering a hormone similar to the luteinizing can play testicular function and their return to normal size.
Because testosterone produces a mouse accumulation in the body can have some anabolic properties but little significant. It is therefore not used by athletes for this purpose.
HCG is used for medical purposes to induce ovulation and treat ovarian disorders in women, or to stimulate the testes do not produce enough testosterone in men. It is used to treat testes that do not descend into the scrotum in children or adolescents. For sports has no practical application, but for athletes who use anabolic androgenic steroids is very useful. As I said above, HCG is similar to luteinizing hormone, which stimulates the testes to secrete testosterone. It is very useful especially during very long cycles of steroids, or when using very high doses. In such situations, the hypothalamus signals the testes to stop producing testosterone and testicular atrophy phenomenon occurs (shrink). Use of HCG will send a signal synthetic, like one sent by LH, and thus produce testosterone in the testicles will continue and will avoid atrophy in a greater or lesser extent. Not only helps to maintain testicular size and function, but also help to bring them to normal, if shrank. Especially when androgen levels are below the limit (because steroids), which could have unintended consequences. Restoring normal testosterone production as quickly poibil is crucial to the completion of a course of steroids. The price paid if these levels are recovering, is losing much of the gain muscle mass, the main reason being cortisol. Cortisol sends a signal to the muscles, which is opposite to that of testosterone. If the problem is not solved cortisol (due to very low levels of testosterone) will quickly devour muscle obtained during the steroid cycle.
