Swirl very gently — HCG is a large glycoprotein (36,000 Da) and can denature if handled roughly. Do not shake. Solution should be clear.”}}, {“@type”: “Question”, “name”: “How should HCG be stored?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “Store lyophilized at 2–8°C (refrigerator) or −20°C (freezer). Reconstituted HCG should be refrigerated at 2–8°C and used within 30 days. Unlike peptides, HCG is sensitive to freezing once reconstituted — do not freeze reconstituted solution.”}}, {“@type”: “Question”, “name”: “What purity is QSC HCG and how is it verified?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “QSC HCG (Human Chorionic Gonadotropin) is ≥99% pure by HPLC with MS-confirmed molecular identity on every batch.

What is HCG??
Human Chorionic Gonadotropin (hCG, CAS 9002-61-3) is a heterodimeric glycoprotein hormone (MW ~36.7 kDa; α-subunit shared with LH/FSH/TSH, unique β-subunit) produced by syncytiotrophoblasts. hCG binds the luteinising hormone/choriogonadotropin receptor (LHCGR) with high affinity — activating Gs/adenylate cyclase → cAMP → PKA signalling — stimulating steroidogenesis in Leydig cells (testosterone production) and in corpus luteum (progesterone maintenance). It is the fundamental tool for studying LH receptor biology, gonadal steroidogenesis, and pituitary-gonadal axis function.
