Description
HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone composed of two subunits — an alpha subunit shared with other gonadotropins and a unique beta subunit that defines its specific activity. It acts primarily on the luteinizing hormone/choriogonadotropin receptor (LHCGR), mimicking the action of luteinizing hormone (LH). In controlled laboratory settings, HCG is studied for its role in stimulating gonadal steroidogenesis, supporting luteal function, and modulating the hypothalamic-pituitary-gonadal (HPG) axis. This makes it a key reference compound in reproductive endocrinology, gonadal-function, and fertility-signaling research.
Important Note
HCG is not approved for human consumption, medical use, or diagnostic purposes. It is supplied strictly for laboratory research only. Handling should be performed by qualified professionals in an appropriate controlled research setting.
