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
