From Wikipedia entry for HCG - human chorionic gonadotropin - - human chorionic gonadotropin - :
In the world of performance enhancing drugs, hCG is increasingly used in combination with various anabolic androgenic steroid (anabolic androgenic steroids) cycles.
When anabolic androgenic steroids are put into a male body, the body's natural negative-feedback loops cause the body to shut down its own production of testosterone via shutdown of the hypothalamic-pituitary-testicular axis (hpta - hypothalamic-pituitary-testicular axis - - hypothalamic-pituitary-testicular axis - ). High levels of AASs that mimic the body's natural testosterone trigger the hypothalamus to shut down its production of gonadotropin-releasing hormone (GnRH) from the hypothalamus. Without GnRH, the pituitary gland stops releasing luteinizing hormone (lh - leutenizing hormone - - leutenizing hormone - ). LH normally travels from the pituitary via the blood stream to the testes, where it triggers the production and release of testosterone. Without LH, the testes shut down their production of testosterone, causing testicular atrophy.
In males, hCG mimics LH and helps restore and maintain testosterone production in the testes. As such, hCG is commonly used during and after steroid cycles to maintain and restore testicular size as well as endogenous testosterone production. However, if hCG is used for too long and in too high a dose, the resulting rise in natural testosterone will eventually inhibit its own production via negative feedback on the hypothalamus and pituitary.
So basically, this late in your PCT - post cycle therapy - - post cycle therapy - , it seems that hCG would be counter-productive.
