What is GHRP-2?
GHRP-2 (Growth Hormone Releasing Peptide-2 (hexapeptide)) is a 6-amino acid synthetic hexapeptide. GHSR-1a agonist with robust GH-releasing activity and moderate HPA co-stimulation (cortisol, prolactin) — greater GH pulse amplitude than ipamorelin but more HPA axis co-activation. Used when moderate co-stimulation is acceptable or desired in the research design.
Research Applications
Robust GH Stimulation
Higher GH pulse amplitude than ipamorelin at equivalent dose
HPA Co-activation
Moderate cortisol/prolactin co-stimulation — included in research design
Ghrelin Axis
Intermediate selectivity between ipamorelin and GHRP-6
GH+Cortisol Models
Research requiring GH alongside glucocorticoid activation
Dose-Response
GH amplitude vs dose characterisation and receptor kinetics

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial, directing water down the inner wall. Swirl gently until dissolved. Both GHRP-2 and GHRP-6 are hexapeptides that dissolve readily to a clear, colourless solution.
How should this peptide be stored?
Store lyophilized at −20°C. Reconstituted at 2–8°C for up to 28 days. GHRPs are relatively stable peptides — avoid repeated freeze-thaw and direct UV exposure.
What purity is this QSC compound and how is it verified?
QSC GHRP-2 and GHRP-6 are ≥99% pure by HPLC with MS identity confirmation on every batch. COA is published on the product page and verifiable via Janoshik.
