Research-Grade Compound

Human chorionic gonadotropin (HCG), CAS 9002-61-3, is a heterodimeric glycoprotein hormone that signals through the LH/hCG receptor (LHCGR) and is produced in quantity by placental trophoblast. Research-grade HCG ships as a lyophilized powder intended solely for in-vitro receptor pharmacology, immunoassay and reproductive biology work.

Purity standard: HCG is sourced to ≥99% by HPLC — sourcing spec.

Buying HCG — Frequently Asked Questions

Does every HCG lot come with a Certificate of Analysis?

Every lot ships against a Certificate of Analysis carrying the lot number, the HPLC purity result and the identity testing performed by an independent laboratory. The >=99% figure is a sourcing specification; the measured value for the specific lot you receive is the number printed on that document.

How should HCG be stored?

Store the lyophilized vial at -20 C, sealed, protected from light and moisture. After reconstitution in bacteriostatic water, hold the solution at 2 to 8 C and use it over a short window, avoiding repeated freeze-thaw cycles. Glycoprotein hormones lose activity through subunit dissociation, so aliquoting into single-use vials is preferable to repeatedly warming one stock.

Is HCG banned by WADA?

Chorionic gonadotropin is prohibited in male athletes at all times under the World Anti-Doping Agency's peptide hormone category. Anti-doping status is listed here for completeness of the regulatory picture; it is not guidance for use in any person.
