GHRP-2
Hexapeptide GH secretagogue for GH pulse and ghrelin research.
Class
Hexapeptide GH secretagogue (ghrelin mimetic)
Half-life
~15–60 min
Studied in
GH pulse and ghrelin-receptor pharmacology studies.
What it is
GHRP-2 is a synthetic hexapeptide ghrelin receptor agonist used as a research probe for GH release and ghrelin pathway pharmacology.
Mechanism studied
GHS-R1a agonist driving GH release with modest cortisol/prolactin activity.
Research notes
- Less GH-selective than ipamorelin — useful for comparative pharmacology studies.
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.
