GHRP-1

First-generation growth hormone-releasing hexapeptide; precursor to GHRP-2/-6.

Scientific Overview

GHRP-1 is the original synthetic ghrelin-mimetic hexapeptide developed by Bowers et al. in the late 1970s. It was the template that gave rise to GHRP-2 and GHRP-6, and is rarely sold today because both successors are stronger and cleaner. Most modern research relies on GHRP-2 instead.
