GHRP-2 vs GHRP-6
Compare GHRP-2 and GHRP-6, two classic growth hormone releasing peptides with distinct potency and side effect profiles. Understand which GH secretagogue fits your research protocol.
GHRP-2
Growth Hormone / GH Secretagogues
GHRP-6
Growth Hormone / GH Secretagogues
Side-by-Side Comparison
Synthetic hexapeptide GHSR-1a agonist that triggers GH secretion via phospholipase C/protein kinase C pathway independent of GHRH; one of the most potent GHRPs available
Synthetic hexapeptide GHSR-1a agonist that stimulates GH release synergistically with endogenous GHRH; suppresses somatostatin and strongly stimulates appetite via ghrelin mimicry
Ghrelin receptor (GHSR-1a) — potent agonist with moderate appetite effect
Ghrelin receptor (GHSR-1a) — strong ghrelin mimetic with pronounced appetite effect

Which Is Right for Your Research?
Choose GHRP-2 for maximum GH release potency with moderate appetite stimulation. Choose GHRP-6 when appetite stimulation via ghrelin pathways is a desired research variable, or for cardioprotection and gastric motility studies.
