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
