HCG is human chorionic gonadotropin (hCG), a 244-amino acid heterodimeric glycoprotein hormone (α and β subunits) and potent LH receptor (LHCGR) agonist studied in gonadotropin axis and steroidogenesis assay models.
Research panels using hCG typically compare its potency and duration of LHCGR activation against native LH, recombinant LH (rLH), and truncated β-subunit analogs to map the contribution of the C-terminal glycopeptide to receptor kinetics. It is also used in germ-cell maturation, trophoblast differentiation, and early implantation signalling model systems.

In research literature, HCG is generally treated as human chorionic gonadotropin (hCG), a 244-amino acid heterodimeric glycoprotein hormone (α and β subunits) and potent LH receptor (LHCGR) agonist studied in gonadotropin axis and steroidogenesis assay models. hCG shares its α-subunit (92 residues) with LH, FSH, and TSH, but the β-subunit (145 residues, with a C-terminal extension carrying O-linked oligosaccharide chains) determines receptor selectivity for the LH/CG receptor (LHCGR). LHCGR is a class A GPCR coupling via Gs to adenylyl cyclase; cAMP/PKA signalling in Leydig cells drives StAR-mediated cholesterol import and CYP11A1-catalysed steroid synthesis, making it the standard reference agonist in Leydig cell steroidogenesis assays. In granulosa cell models, LHCGR activation by hCG triggers the LH surge equivalent, providing a controlled in vitro stimulus for luteinisation and progesterone synthesis studies. The unique O-glycosylated C-terminal extension of the β-subunit confers a substantially longer serum half-life than LH, making hCG the preferred tool in pharmacokinetic receptor-occupancy modelling.
Research panels using hCG typically compare its potency and duration of LHCGR activation against native LH, recombinant LH (rLH), and truncated β-subunit analogs to map the contribution of the C-terminal glycopeptide to receptor kinetics. It is also used in germ-cell maturation, trophoblast differentiation, and early implantation signalling model systems. For laboratory teams, the practical emphasis is usually on sequence identity, receptor or pathway relevance where documented, and whether HCG behaves consistently across stability, purity, and analytical verification workflows. Variant labels on this page support clearer internal referencing when multiple labelled variants are under review.
Potential research applications for HCG should be framed strictly in analytical and laboratory terms. Typical reasons a team might review this product page include:
Handling decisions should always follow the vial label, internal SOPs, and any product-specific documentation. A conservative laboratory baseline for HCG is:
If a product-specific file is not attached to this listing, the wider COA library remains the correct reference point for current published documentation. The COA section is useful for confirming how the product is labelled in the catalogue, whether purity information has been published, and whether the laboratory record for the material is complete before bench use.
When teams compare HCG with PT-141, Glow, and BPC-157 + TB-500, COA access also helps keep comparator decisions grounded in documented material identity rather than assumption. That is especially important for research pages that combine pricing, variant selection, and analytical records on a single URL.

It brings together 1 labelled variant: 5000iu, current pricing context, stock visibility, COA access, and internal links to related catalogue pages so a laboratory buyer can review the material from a single reference URL.
HCG is generally discussed as human chorionic gonadotropin (hCG), a 244-amino acid heterodimeric glycoprotein hormone (α and β subunits) and potent LH receptor (LHCGR) agonist studied in gonadotropin axis and steroidogenesis assay models. The most relevant background is sequence behaviour, pathway or receptor context where documented, and analytical consistency under controlled laboratory conditions.
Use the label, COA, and internal SOPs as the primary guide. In general, store the material under controlled laboratory conditions, minimise avoidable environmental exposure, and keep variant tracking records current.
This page links the broader COA library when a product-specific document is not attached. Laboratories should use the published documentation set that is currently available for the listing.
No. The page should be interpreted strictly in a research and laboratory context. It does not provide dosage guidance, treatment claims, or human or animal use instructions.
