Explore HCG hormone research, chorionic gonadotropin biology, approved product indications, evidence limitations, and differences from HGH.
Human chorionic gonadotropin (hCG) is a glycoprotein hormone made of alpha and beta subunits. It is distinct from human growth hormone (HGH) and from short synthetic research peptides.
Urinary-derived chorionic gonadotropin and recombinant choriogonadotropin alfa are product-specific forms. Their labeling, preparation, and approved indications must be considered separately.
HCG acts through the luteinizing-hormone/choriogonadotropin receptor and is involved in gonadal hormone signaling. Its role in pregnancy testing is a biomarker use, distinct from an administered intervention.
Clinical evidence includes reproductive and endocrine settings. Registry counts on this page require an explicitly named hCG intervention; studies that only measure pregnancy hCG or other biomarkers are not counted as administered-hCG research.
Prescription hCG products have specific labeled indications. The PREGNYL label states that hCG has not been demonstrated effective as an adjunct for obesity treatment. Product approval does not extend to every vendor vial or wellness claim.
HCG is a glycoprotein gonadotropin with alpha and beta subunits. The PREGNYL label describes luteinizing-hormone-like activity and specific reproductive and endocrine indications. These statements concern the labeled product, not all preparations sold under an HCG name. PREGNYL prescribing information, DailyMed
HCG should not be presented as an established weight-loss compound. PREGNYL labeling specifically rejects demonstrated benefit as an adjunct to obesity treatment and distinguishes its approved indications from weight-loss claims. PREGNYL indications and limitations
