HCG (Human Chorionic Gonadotropin) is a heterodimeric glycoprotein hormone. Its β-subunit shares 85% homology with luteinizing hormone (LH) and binds the same LH/CG receptor (LHCGR), as described in peer-reviewed literature (ncbi.nlm.nih.gov). This research-grade lyophilized powder is provided with full analytical documentation. For Research Use Only. Not for human use.

- Full Certificate of Analysis (COA) with HPLC, SDS-PAGE, bioactivity (Leydig cell testosterone assay), and endotoxin testing
- Manufactured in GMP-aligned, ISO-compliant facilities
- Suitable for LH receptor signaling, steroidogenesis, and HPG axis research
Research-Referenced Attributes (Based on scientific literature only; not therapeutic claims.)
- Potent LH receptor agonist as documented in preclinical and in vitro research models (ncbi.nlm.nih.gov)
- Sustained half-life (~24–36 hours) vs. LH (~20 minutes) due to high sialylation, as reported in published studies (pmc.ncbi.nlm.nih.gov)
- Used in in vitro research models of Leydig cell function and gonadotropin signaling
- Investigated in laboratory models of steroidogenesis and gonadotropin signaling pathways
Why Researchers Choose This HCG Peptide

Frequently asked questions
How should I reconstitute this peptide?
Use bacteriostatic water for short-term lab storage. Direct the diluent down the side of the vial, swirl gently — do not shake.
What is the shelf life?
Lyophilized peptide stored at −20°C is stable for 24+ months. Reconstituted peptide should be refrigerated and used within 2–4 weeks.
Do you ship internationally?
We currently ship within the United States only. International researchers should contact our bulk team for institutional quotes.
