GHRP-6: An Overview of the Research

GHRP-6 is another of the earlier growth-hormone-releasing peptides, closely related to GHRP-2 and commonly studied alongside it. This overview covers what GHRP-6 is and how it compares within the class.

What Is GHRP-6?

GHRP-6 (Growth Hormone-Releasing Peptide-6) is a synthetic peptide in the growth-hormone secretagogue class, acting at the ghrelin / growth-hormone-secretagogue receptor. It is one of the earliest compounds in this group and a frequent reference point in the literature.

How Does GHRP-6 Work?

GHRP-6 is studied for its action at the ghrelin receptor. Like GHRP-2, it is described as less selective than newer compounds such as Ipamorelin, with broader effects across additional pathways — a property often noted when comparing the secretagogues.

GHRP-6 vs GHRP-2 vs Ipamorelin

The three are studied together as a class. GHRP-6 and GHRP-2 are the earlier, less selective compounds; Ipamorelin is the more selective one. The comparison is a common subject in growth-hormone-axis research.
