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.

Research Applications

Leydig Cell Steroidogenesis

LHCGR activation, testosterone biosynthesis, StAR/CYP11A1/CYP17A1 enzyme expression

LH Receptor Biology

cAMP/PKA signalling, receptor internalisation, LHCGR desensitisation kinetics

Corpus Luteum Function

Progesterone maintenance, luteal phase studies, luteolysis prevention models

Male Reproductive Research

Testicular descent, Leydig cell function, spermatogenesis support in hypogonadism models

HPG Axis Studies

Hypothalamic-pituitary-gonadal axis, LH receptor cross-reactivity with FSH-α subunit research

Frequently Asked Questions

How do I reconstitute HCG?
Add 1–2mL bacteriostatic water to the lyophilized HCG vial, directing water down the inner wall. Swirl very gently — HCG is a large glycoprotein (36,000 Da) and can denature if handled roughly. Do not shake. Solution should be clear.
How should HCG be stored?
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.
What purity is Vesta HCG and how is it verified?
Vesta HCG (Human Chorionic Gonadotropin) is ≥99% pure by HPLC with MS-confirmed molecular identity on every batch. COA is published on the product page and independently verifiable at verify.janoshik.com.
