Human Chorionic Gonadotropin.
Human chorionic gonadotropin is a placental glycoprotein hormone structurally and functionally similar to luteinizing hormone (LH). Clinically important in reproductive medicine; used as a research tool for stimulating gonadal steroidogenesis. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.

HCG binds the LH/CG receptor (LHCGR) — the same receptor as LH. In males it stimulates Leydig cell testosterone production; in females it supports corpus luteum progesterone production. The long half-life (24-36 hr) vs. LH (~20 min) is a function of the heavily glycosylated β-subunit.
Multiple HCG products are FDA-approved for various fertility indications (Ovidrel, Pregnyl, etc.). WADA prohibited in males (S2). Research-grade material is available for non-clinical research applications only.
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
HCG is a protein (237 amino acids, approximately 36,700 Da). Formula: Heterodimer α/β.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).
Multiple HCG products are FDA-approved for various fertility indications (Ovidrel, Pregnyl, etc.). WADA prohibited in males (S2). Research-grade material is available for non-clinical research applications only.
All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
