GHRP-2 (Growth Hormone-Releasing Peptide-2, also known as Pralmorelin) is a synthetic hexapeptide (D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH₂) that acts as a selective agonist of the growth hormone secretagogue receptor (GHS-R). GHRP-2 is generally considered the most potent of the hexapeptide GH secretagogues, producing robust GH release with peak plasma levels approximately 15-30 minutes post-administration.

Compared to GHRP-6, GHRP-2 demonstrates higher potency for GH release while exhibiting less pronounced effects on appetite and prolactin secretion, making it a more selective tool for GH secretion studies. Research has examined GHRP-2's influence on IGF-1 production, body composition parameters, and metabolic rate in preclinical models.
