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.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

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.

Listing details

Compound: HCG (Human Chorionic Gonadotropin)
Synonyms: hCG, Choriogonadotropin
Class: Heterodimeric glycoprotein hormone
Format: Lyophilized (freeze-dried) powder
Vial strength: 1000 IU
Vials per kit: 10
Sold by: Uther Peptide
Ships from: China
Lab report: Not yet published

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 1000 IU vial dissolved in 2 mL gives 500 IU/mL, or 1000 IU/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

Why do pregnancy tests detect hCG and not LH?

Tests use antibodies directed at the hCG beta subunit, the part that differs from LH. Because the alpha subunit is shared across several hormones, targeting beta is what gives the assay its specificity. The same principle matters in laboratory work, where beta-specific immunoassays quantify hCG without interference from related hormones.

What is the difference between urinary and recombinant hCG?

Urinary hCG is extracted and purified from the urine of pregnant women, while recombinant hCG is produced in engineered cell lines. Both contain the same polypeptide chains, but their glycosylation profiles and impurity patterns can differ, which can affect analytical results and the comparability of studies that used different sources.

How much HCG (Human Chorionic Gonadotropin) is in this listing?

10 vials of 1000 IU each. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does Uther Peptide get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
