What is HCG (Human Chorionic Gonadotropin)?

HCG is a two-subunit glycoprotein hormone naturally produced by placental tissue during pregnancy, sharing a common alpha subunit with LH, FSH and TSH alongside a hormone-specific beta subunit. Pharmaceutical hCG, whether purified from urine or produced recombinantly, is an approved medicine used clinically for specific fertility indications.

This listing is HCG (Human Chorionic Gonadotropin) from Lilipeptide (China), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

HCG binds the luteinizing hormone/choriogonadotropin receptor (LHCGR), mimicking LH activity to stimulate testosterone synthesis in testicular Leydig cells and progesterone production by the corpus luteum, making it a standard tool for probing gonadal steroidogenesis.

Research status

In reproductive-endocrinology research, hCG is used to study the hypothalamic-pituitary-gonadal axis, gonadal function and steroidogenic response, and it also serves clinically as an approved fertility treatment; research-grade material sold here is intended for laboratory study, not clinical administration.

Questions

Why is hCG measured in IU instead of mg?

Because the biological potency of glycoprotein hormones can vary with glycosylation pattern, hCG is standardized and dosed by international units, a measure of biological activity, rather than by raw mass.

Is research-grade hCG the same molecule as the prescription fertility drug?

The active hormone is the same glycoprotein, but prescription hCG is manufactured, tested and labeled under pharmaceutical regulatory standards for clinical use, while research-grade material is intended strictly for laboratory study.
