In research settings, it is studied for its role in receptor-mediated endocrine signaling, particularly in models involving gonadotropin biology, steroidogenic pathway activity, and reproductive hormone regulation.\u003c\/p\u003e\n\u003ch4 data-start=\"726\" data-end=\"760\"\u003eMechanism of Action \u0026amp; Applications\u003c\/h4\u003e\n\u003cp data-start=\"762\" data-end=\"1208\"\u003eHCG is studied for its activity at the luteinizing hormone\/choriogonadotropin receptor (LHCGR). In laboratory research, this makes it useful for examining receptor activation, cyclic AMP signaling, gonadal steroidogenesis, and broader endocrine pathway coordination. It is commonly used in studies involving reproductive endocrinology, gonadotropin receptor biology, ovarian and testicular signaling models, and hormone-response pathway research.\u003c\/p\u003e\n\u003ch4 data-start=\"1210\" data-end=\"1226\"\u003eResearch History\u003c\/h4\u003e\n\u003cp data-start=\"1228\" data-end=\"1548\"\u003eHCG has been studied for decades as one of the key hormones involved in reproductive endocrinology. Early research focused on its identification in pregnancy-related biology, followed by broader investigation into its receptor activity, structural subunits, and role as a model ligand in gonadotropin signaling research.\u003c\/p\u003e\n\u003ch4 data-start=\"1550\" data-end=\"1570\"\u003eChemical Information\u003c\/h4\u003e\n\u003cp data-start=\"1572\" data-end=\"1730\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eCAS Number: 9002-61-3\u003cbr\u003eMolecular Formula: Not publicly standardized\u003cbr\u003eMolecular Weight: Approximately 36.7 kDa\u003cbr\u003ePubChem ID: Not publicly standardized\u003cbr\u003ePurity: ≥99%\u003c\/p\u003e","brand":"Phase 1 Peptides","offers":[{"title":"5000 IU","offer_id":46106298712236,"sku":"P1P-HCG5","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/6660\/1900\/files\/HCG_5000IU.png?v=1775288755","url":"https:\/\/phase-1-peptides.myshopify.com\/products\/hcg","provider":"Phase 1 Peptides","version":"1.0","type":"link"}
