02Mechanism of Action
GHRP-2 (pralmorelin) is a synthetic hexapeptide that acts as an agonist at the growth-hormone secretagogue receptor (GHS-R1a), stimulating growth-hormone release from the pituitary in research models.
It is studied as a potent GH secretagogue, with literature noting modest effects on ACTH, cortisol, and prolactin relative to highly selective agents — a useful contrast in secretagogue-specificity research.

05Frequently Asked Questions
What is GHRP-2?
GHRP-2 (pralmorelin) is a growth-hormone-releasing hexapeptide studied as a GHS-R1a agonist for GH secretion in research models. It is a research-use-only compound.
What is the CAS number of GHRP-2?
GHRP-2 has CAS number 158861-67-7 and a molecular weight of approximately 817.97 g/mol.
How does GHRP-2 compare to Ipamorelin?
Both are ghrelin-receptor agonists studied as GH secretagogues; Ipamorelin is noted for greater selectivity, while GHRP-2 is studied as a potent secretagogue with comparatively broader hormone effects.
