Sermorelin is a synthetic analog of the first 29 amino acids of growth hormone-releasing hormone. It is used in research to stimulate endogenous GH signaling upstream rather than acting as growth hormone itself. On a site page, it should be described as a research peptide for endocrine and GH-axis studies.
