HCG
Monograph · BHCG
Human chorionic gonadotropin. LH-mimetic — stimulates testicular Leydig cells to produce testosterone. Used clinically in fertility and TRT-axis preservation.
How it clearsHalf cleared in ~2d. Most (~96%) gone by ~8d.
FDA-approved as Pregnyl, Novarel, Ovidrel for fertility and pediatric cryptorchidism. Off-label use during testosterone replacement therapy to maintain testicular size and intratesticular testosterone (fertility preservation). Compounded versions are common; brand products are expensive.
Documented hormonal pathway with strong mechanistic support. Response is not uniform — users with significant baseline deficiency feel signal earlier and more clearly than those near the normal range. If response feels subtle, that is often a baseline reading, not a compound failure.
Compounded HCG quality varies; verify pharmacy. False positives on home pregnancy tests are real. TRT-axis use should be supervised by a physician with bloodwork.
