Research brief · Hormone
HCG
LH-receptor agonist glycoprotein hormone used in HPG-axis research.
Class
Glycoprotein hormone (LH-receptor agonist)
Half-life
~24–36 h
Studied in
HPG-axis, gonadal steroidogenesis and fertility research models.
What it is
HCG is a placental glycoprotein hormone that activates the LH/CG receptor. Research applications include HPG-axis modulation, Leydig and theca cell steroidogenesis assays and fertility models.
Mechanism studied
Binds LH/CG receptors to drive gonadal steroidogenesis.
Research notes
- Glycoprotein — handled differently from small peptide tool compounds.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
