HCG 5000iu

A well-characterized glycoprotein hormone with multiple FDA-approved medical uses. Used as a standard reference compound in reproductive and endocrine research for decades, with one of the most established safety profiles in the field.

How It Works

The Target

LH/hCG receptors (LHCGR) primarily on Leydig cells in the testes and granulosa cells in the ovaries. hCG is a naturally occurring glycoprotein hormone produced during pregnancy.

The Mechanism

Mimics luteinizing hormone (LH) at its receptor, triggering the same downstream cascade: Gs protein activation, cAMP production, PKA signaling, and ultimately steroidogenesis. In males, this stimulates testosterone production. In females, it triggers ovulation and supports corpus luteum function.

Why It Matters

Multiple FDA-approved medical uses with decades of clinical data. In research contexts, hCG is used to maintain intratesticular testosterone during exogenous hormone administration, preserving spermatogenesis and testicular function.
