Description

HCG 5000IU — glycoprotein hormone for reproductive and endocrine research in Australia. University-verified potency. Same-day Sydney dispatch.

HCG (Human Chorionic Gonadotropin) is a large glycoprotein hormone consisting of alpha and beta subunits. Unlike simple peptides, it features complex tertiary structure and extensive glycosylation affecting its biological activity and receptor binding.

What the Research Shows

HCG binds to and activates the LH/CG receptor, stimulating testosterone production in Leydig cells and progesterone production in ovarian cells. Its structural similarity to luteinising hormone but longer half-life makes it valuable for studying gonadotropin physiology.

Research has extensively characterised its receptor binding kinetics, signal transduction pathways, and downstream effects on steroidogenesis and the hypothalamic-pituitary-gonadal axis.

Why Australian Researchers Choose Purpose Labs

Every batch is tested at a leading Australian university — potency verified. No generic overseas certificates.

Important: Do not freeze HCG — freezing damages the protein’s complex tertiary structure. Store refrigerated only.
