GHRP-2: An Overview of the Research

GHRP-2 is one of the earlier growth-hormone-releasing peptides, frequently referenced as a comparison point for the more selective secretagogues. This overview covers what GHRP-2 is and how it sits within the class.

What Is GHRP-2?

GHRP-2 (Growth Hormone-Releasing Peptide-2) is a synthetic peptide in the growth-hormone secretagogue class. It acts at the ghrelin / growth-hormone-secretagogue receptor and is one of the earlier, well-characterised compounds in this group.

How Does GHRP-2 Work?

GHRP-2 is studied for its action at the ghrelin receptor, prompting growth-hormone release through that pathway. Compared with the more selective Ipamorelin, GHRP-2 is described as having broader effects across additional pathways, which is why it is frequently used as a comparison point in secretagogue research.

GHRP-2 vs GHRP-6 vs Ipamorelin

GHRP-2, GHRP-6 and Ipamorelin all act on the same receptor but differ in selectivity. GHRP-2 and GHRP-6 are the earlier, less selective compounds; Ipamorelin is noted for greater selectivity. Researchers study the group together to compare these profiles.
