HCG

CAS: 9002-61-3

HCG is a research peptide in the sexual health / hormonal category. HCG is a glycoprotein hormone that shares structural homology with luteinizing hormone (LH) and binds to the same LH/CG receptor (LHCGR). MiPeptidos offers HCG in 4 sizes with 99.5% verified purity and full analytical documentation.

How HCG Works

HCG is a glycoprotein hormone that shares structural homology with luteinizing hormone (LH) and binds to the same LH/CG receptor (LHCGR). In males, it stimulates Leydig cells to produce testosterone, maintaining testicular size and function. In females, it triggers ovulation and supports corpus luteum progesterone production. The extensive glycosylation (including sialic acid residues) dramatically extends its half-life compared to LH. HCG is used to maintain endogenous testosterone production during exogenous hormone therapy.

Research Applications

1
Male hypogonadism and testosterone restoration
2
Female fertility and ovulation induction
3
Testicular function preservation during TRT
4
Pregnancy testing and monitoring

Frequently Asked Questions

HCG (CAS: 9002-61-3) is a research compound, with a molecular weight of ~36,700 Da (heterodimeric glycoprotein; ~14.5 kDa alpha + ~22.2 kDa beta subunit) in the Sexual Health / Hormonal category. HCG is a glycoprotein hormone that shares structural homology with luteinizing hormone (LH) and binds to the same LH/CG receptor (LHCGR). In males, it stimulates Leydig cells to produce testosterone, maintaining testicular size and function. Researchers commonly investigate HCG for Male hypogonadism and testosterone restoration, Female fertility and ovulation induction, Testicular function preservation during TRT. Every vial from MiPeptidos includes batch-specific analytical documentation.
HCG is available in 4 sizes (1000iu, 2000iu, 5000iu, 10000iu), so reconstitution volume depends on which vial you have. For the 1000iu size, add 1mL of bacteriostatic water; for the 10000iu size, use 1mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted HCG at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
HCG (human chorionic gonadotropin, ~36,700 Da glycoprotein) mimics LH by binding the same LH/CG receptor (LHCGR), directly stimulating Leydig cells to produce testosterone. Gonadorelin works upstream — it is synthetic GnRH that stimulates the pituitary to release LH. HCG has a much longer half-life (24-36 hours vs 2-4 minutes for Gonadorelin) thanks to extensive glycosylation, particularly sialic acid residues. MiPeptidos carries both for researchers studying different levels of the HPG axis.
Store lyophilized HCG at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, HCG has a reported half-life of ~24-36 hours, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every HCG order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-HCG-2600115, tested January 21, 2026) shows 99.5% purity by HPLC, mass spectrometry confirmation at ~36,700 Da (heterodimeric glycoprotein; ~14.5 kDa alpha + ~22.2 kDa beta subunit), endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
