What Is GHRP-2?
GHRP-2 is one of the most potent synthetic growth hormone secretagogues ever studied — a six-amino-acid peptide that tells your pituitary gland to release a pulse of growth hormone by mimicking ghrelin, the body's own "hunger hormone." That's a meaningful distinction from GHRH-based peptides: GHRP-2 works through an entirely different receptor, which is why researchers have long been interested in combining the two approaches.
In Japan, it's been approved under the name Pralmorelin as a diagnostic agent for growth hormone deficiency testing.[1] In the United States, GHRP-2 carries no FDA approval and is classified for research purposes only. It's not available through compounding pharmacies or by prescription for therapeutic use in the US.
Despite that status, GHRP-2 has shown up in nutritional supplements and black-market injection products — a pattern that reflects both genuine interest in its GH-releasing effects and the risks that come with unregulated sourcing.[2][3]
GHRP-2 stimulates growth hormone release by binding the ghrelin receptor (GHS-R1a) — a completely different pathway than GHRH-based peptides like CJC-1295.
