GHRP-6 — compound background
Synthetic hexapeptide, met-enkephalin analogue and ghrelin-receptor agonist
GHRP-6 was among the first synthetic growth hormone secretagogues, developed from met-enkephalin analogues in the 1980s — years before the ghrelin receptor it acts on was even identified. It is a genuine piece of pharmacological history: the compound was found first and its target second, and that search for the endogenous ligand of its receptor eventually led to the discovery of ghrelin in 1999.
Solubility & reconstitution
Water-soluble, though noticeably more hydrophobic than most short peptides here because two tryptophans and a phenylalanine give it substantial aromatic character. Some lots benefit from a small volume of dilute acetic acid before dilution to final volume.
Storage
Sealed at -20 °C, dry and protected from light. Refrigerate at 2–8 °C with strict light protection. GHRP-6 contains two tryptophan residues — more photo-labile side chains than any other compound in this catalogue.
Commonly worked with for 2–3 weeks at 2–8 °C.
Stability
The D-amino acids at positions 2 and 5 confer good resistance to enzymatic degradation, but offer no protection whatsoever against photo-oxidation. Enzymatic stability and chemical stability are separate properties and this compound illustrates the distinction well.
Reading the Certificate of Analysis
Confirm the mass near 873.0 Da. Because two tryptophans can each oxidise independently, look for both +16 and +32 Da species. Yellowing of the material is the visual correlate of the same process.
