HCG(Human Chorionic Gonadotropin)
HCG (Human Chorionic Gonadotropin) is a high-purity, laboratory-grade glycoprotein hormone composed of alpha and beta subunits. In the landscape of advanced endocrinology and physiological research, HCG is highly distinguished by its structural and functional similarity to Luteinizing Hormone (LH). By binding to the shared LH/hCG receptor with higher affinity and a significantly longer half-life than endogenous LH, HCG provides researchers with a powerful experimental model to stimulate Leydig cells in males and investigate the induction of testosterone biosynthesis. It serves as an essential tool for researching the restoration of the Hypothalamic-Pituitary-Gonadal (HPG) axis, germ cell maturation, and the molecular signaling involved in steroidogenesis.
Our HCG is processed in an ISO 9001:2015 certified environment utilizing advanced chromatographic purification technology. We achieve a superior level of purity, ensuring the product is free from non-specific urinary proteins and pyrogens. Each vial is standardized to its specific potency—available in 1000iu, 2000iu, 5000iu, and 10000iu—guaranteeing the biological activity and reproducibility required for high-stakes hormonal research and metabolic assays.

Key Features & Quality Assurance
Advanced Lyophilization Stability
Our proprietary vacuum-sealing process ensures the HCG powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid, clear reconstitution and protects the complex glycoprotein structure from thermal degradation.
Consistent Biological Potency
We utilize standardized bioassays to calibrate every vial, ensuring that the international units (iu) provided are accurate and produce predictable physiological responses in all research designs.
Reconstitution & Storage
Reconstitution Guide
-
Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the HCG cake is at the base.
-
Solvent: Reconstitute with Sterile Water or 0.9% Normal Saline.
-
Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.
Storage Protocols
-
Long-term: Store at -20°C (Maintains potency for up to 24 months).
-
Short-term: Stable at 2–8°C for up to 3 months.
-
Post-Reconstitution: Store at 2–8°C and utilize within 30 days (if using Bacteriostatic Water) or 7 days (if using Sterile Water) for optimal stability.
