Chorionic Gonadotropin is a polypeptide hormone. It is found in the female body during the early months of pregnancy. Chorionic Gonadotropin is present in significant amounts only during pregnancy. FDA-approved uses of HCG are the treatment of hypogonadism and cryptorchidism in men and infertility in women.

Human Chorionic Gonadotropin (HCG) in Sports

The main reason for HCG usage by athletes is to increase the endogenous testosterone production during or at the conclusion of cycles. Most anabolic steroids taken in doses to promote muscle gains strongly influence the Hypothalamic-Pituarity-Testes Axis (HTPA) and suppress endogenous test production.

Hypothalamic-Pituarity-Testes Axis HTPA feedback mechanism

Hypothalamus stimulates Pituarity Gland (Hypophysis)
Pituarity Gland (Hypophysis) release Gonadotrophic Hormones
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
FSH and LH hormones stimulate the testes to produce and secrete more testosterone
Increasing endogenous testosterone production.

HCG Pharmacodynamics

HCG mimics the action of the Gonadotropin luteinizing hormone LH and is used as an exogenous form of LH. It is crucial to have high levels of LH in order to have or restore normal endogenous testosterone production.

HCG General Administration

Intramuscular injection – peak concentration in 6 hours
Subcutaneous injection – peak concentration 16-20 hours

HCG Administration Women

Women do not use HCG for physique or performance purposes. The only use of HCG by women is to treat infertility and to induce pregnancy.

HCG Administration Men

The most common use of HCG by athletes and bodybuilders is on cycle to preserve testicular integrity or as part of Post Cycle Therapy (PCT).
All Pros and responsible steroid users know about the importance of restoring endogenous testosterone production. The most common PCT protocol is 2000-3000IU 1-3 times/week for no longer than three weeks.
Please note that if used for too long or at the higher than recommended dosages, HCG could desensitize the testes to LH hormone and slower the recovery process.
