GHRP-2
Synthetic hexapeptide GH secretagogue producing a strong GH pulse via the ghrelin receptor.
01 · What is GHRP-2?
GHRP-2 (growth hormone-releasing peptide 2) is a synthetic hexapeptide that stimulates GH secretion through the ghrelin receptor (GHSR-1a). It produces a strong GH pulse along with measurable appetite stimulation and mild cortisol/prolactin elevation — a broader effect profile than the more selective Ipamorelin. It is among the most-studied peptides of the GHRP class in human and animal research.
