HCG for Testosterone Production

HCG (Human Chorionic Gonadotropin) is a hormone that is structurally similar to Luteinizing Hormone (LH), the hormone released by the pituitary gland that signals the testes to produce testosterone. In the context of Testosterone Replacement Therapy (TRT) or anabolic steroid cycles, the body's natural LH production is suppressed, which can cause the testes to become dormant and shrink. HCG is used to mimic LH, directly stimulating the Leydig cells in the testes to produce testosterone and maintain their size and function. It is often used either during a cycle to prevent shutdown or as part of a Post-Cycle Therapy (PCT) protocol to help "kickstart" the system's natural recovery. By preserving the function of the reproductive axis, HCG plays a key role in maintaining hormonal health and ensuring a smoother transition off of suppressive compounds.
