HCG 5000IU (10 Vials / Kit)

HCG (Human Chorionic Gonadotropin) at a glance

Human chorionic gonadotropin is not a short synthetic peptide but a heavily glycosylated protein hormone. It consists of an alpha subunit, identical to the one found in LH, FSH and TSH, paired non-covalently with a beta subunit that gives hCG its distinct activity and longer persistence in circulation. Placental syncytiotrophoblast cells produce it in early pregnancy, which is why it is the analyte in pregnancy tests. Pharmaceutical supplies are either purified from urine or expressed recombinantly in mammalian cells.

Price and availability

This is UWA Biotech‘s kit of 10 vials at 5000IU each, dispatched from the United States. It is listed at $95.00. Your payment waits in escrow until you confirm the parcel arrived, and only then is it released to the brand.

What it is studied for

hCG binds the luteinizing hormone/choriogonadotropin receptor, a G-protein-coupled receptor with a large extracellular domain that recognizes both LH and hCG. Receptor activation chiefly raises cyclic AMP and protein kinase A activity, though other pathways have been described. In the testis, the main targets are Leydig cells, where signaling drives steroidogenic enzymes; in the ovary, hCG sustains the corpus luteum and its output during early pregnancy. Extra glycosylation, particularly on the beta subunit's C-terminal extension, explains why it persists longer than LH, a property exploited in experimental designs that need sustained receptor stimulation.

Research and regulatory status

Few compounds sold in research marketplaces have a longer clinical history. hCG preparations are approved prescription medicines for specific fertility indications in women and men, and some jurisdictions apply additional controls. It is also prohibited for male athletes under anti-doping rules. Research-grade vials are not those regulated products: they are not made under pharmaceutical manufacturing standards, and their labeled potency depends entirely on the supplier's own testing, which is why independent reports matter here.

Checking the lab data

Because hCG is a glycoprotein, standard peptide methods tell only part of the story. Mass spectrometry yields a broad envelope rather than one sharp peak, reflecting glycan variability, and SDS-PAGE can confirm subunit sizes. HPLC purity is useful, but potency is expressed in international units and ideally verified with an immunoassay or bioassay. A report giving only an HPLC percentage cannot confirm biological activity. Expect a white lyophilized cake.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 5000 IU vial dissolved in 2 mL gives 2500 IU/mL, or 5000 IU/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
