GHRP-2 is a synthetic hexapeptide that acts as a potent agonist at the ghrelin receptor (GHS-R1a), stimulating pulsatile growth hormone release from the anterior pituitary. It is among the most potent GH secretagogues studied in preclinical research.
GHRP-2 has been the subject of numerous studies examining pituitary function, GH pulse dynamics, and IGF-1 modulation. It also stimulates cortisol and prolactin to a moderate degree. It is frequently co-administered with CJC-1295 in research protocols to examine synergistic GH release.
