Description
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates growth hormone release by activating the ghrelin receptor (GHS-R1a). This potent GH secretagogue also increases appetite.
Mechanism of Action
GHRP-2 activates the ghrelin receptor on pituitary somatotrophs, triggering GH release. Studies show robust GH responses in adolescents (Onuki et al., 2024) and the peptide is used clinically for GH stimulation testing (Ghigo et al., 1997).
Research Applications
- Growth hormone secretion studies (Onuki et al., 2024)
- GH axis diagnostics (Ghigo et al., 1997)
- Appetite regulation research
- Combined GHRH/GHRP synergy

Verification
Storage & Handling
Storage
GHRP-2 is supplied as a lyophilized powder. Keep it sealed, dry, and away from light until reconstitution.
Reconstitution
Let the vial reach room temperature before opening, then add solvent slowly down the vial wall — do not shake.
Stability
Lyophilized material is stable when frozen. Once reconstituted, keep it cold and minimise handling to preserve integrity.
Research Overview
GHRP-2 is a synthetic peptide compound used in laboratory research settings. Researchers studying growth hormone releasing hormone pathways use this compound to investigate cellular signaling pathways, receptor binding affinities, and structure-activity relationships. Each batch is manufactured under controlled conditions and verified through HPLC and mass spectrometry analysis to ensure consistency across experimental replicates.

Frequently Asked Questions
What purity is GHRP-2?
Each lot of GHRP-2 is verified to ≥99% by HPLC and confirmed by mass spectrometry. Results are documented in a batch-specific Certificate of Analysis.
Does GHRP-2 include a Certificate of Analysis?
Yes. A batch-specific Certificate of Analysis for GHRP-2 documents its purity and identity and is available on our COA page.
How should GHRP-2 be stored?
GHRP-2 is supplied as a lyophilized powder. For short-term storage keep it refrigerated; for long-term storage keep it frozen, away from light and moisture.
How is GHRP-2 shipped?
Orders ship at a $15 flat rate, free on orders over $199, in discreet, insulated packaging. Domestic delivery typically takes 1–3 business days.
Can GHRP-2 be used on humans or animals?
No. GHRP-2 is supplied strictly for in-vitro laboratory research. It is not for human or veterinary use, consumption, or diagnostic or clinical applications.
