Description
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone naturally produced by trophoblastic cells of the placenta during pregnancy, functioning through the LH/hCG receptor (LHCGR) on gonadal cells. HCG is one of the most extensively-studied glycoprotein hormones in the academic and clinical research literature spanning multiple decades. Structurally, HCG consists of two subunits: an α-subunit (shared with LH, FSH, and TSH) and a unique β-subunit that confers specific receptor binding, coupled through non-covalent interactions with characteristic glycosylation patterns. This 5000 IU lyophilized presentation is offered for laboratory research applications investigating LH/hCG receptor pharmacology, glycoprotein hormone chemistry, gonadotropin research, and comparative pharmacology across the broader glycoprotein hormone family (LH, FSH, TSH). HCG has been characterized extensively in academic research literature for LHCGR receptor binding, cAMP/PKA signaling cascade activation, and downstream steroidogenic pathway research in cell research models. The compound is supplied here strictly for laboratory research applications and remains a research-use-only compound in this presentation.

COA Verification Notice: Even if the vial label or product image states a certain concentration, always go by the COA for the true verified value. We reference the COA to determine the verified IU potency and purity of each batch, regardless of what the label or product image indicates. For HCG specifically, we prioritize verified IU potency testing as underdosing is a documented industry-wide concern for grey-market glycoprotein hormone material.
