GHRP-6 (growth hormone releasing peptide 6) is a synthetic compound made of six amino acids. It can elicit the release of growth hormone (GH)1. Early work on GHRP-6 and similar peptides indicated that they have no structural similarity to growth hormone releasing hormone, however2. There are two analogs of GHRP-6; GHRP-6 peptide and [D-Lys-3]-GHRP-6. [D-Lys-3]-GHRP-6 has an antagonist effect on the GH secretagogue receptor (GHS-R), or the receptor for ghrelin3. Therefore, such a peptide may be used in animal studies that assess the role of this important biomolecule in various processes related to hunger and metabolic regulation. For example, ghrelin may have a role in enhancing the release of insulin in response to food intake, through the release of GLP-1 from specialized cells in the intestine4. [D-Lys-3]-GHRP-6 has demonstrated the ability to counteract this effect4. It may also be used to determine the locations of the GHS-R, e.g. in the ventral tegmental area of the brain3. [D-Lys-3]-GHRP-6 has demonstrated the ability to reduce the extent of DNA synthesis in the gastric glands of infant rats, indicating a role for ghrelin in the development of the stomach after birth5.

The GHRP-6 peptide, on the other hand, has a dose-dependent agonist effect on the GHS receptor6. However, it appears not to match ghrelin in terms of specificity6. GHRP-6 has demonstrated positive effects on organ growth and regeneration in various studies. Its administration resulted in a threefold increase in the migration, but not proliferation, of rat-intestine epithelial cells, indicating a role for the peptide in restoring gut function7. Intraperitoneal GHRP-6 peptide (at a concentration of 120 μg/kg) also significantly inhibited the effects of an animal model of multiple organ damage (i.e. ischemia-reperfusion injury)7. A combination of GHRP-6 and recombinant human epidermal growth factor (administered at concentrations of either 100 or 600 μg per kg) had a significantly detrimental effects on the neurological damage expected as a result of experimentally-induced ischemic stroke in gerbils8.
