Medical supervision helps reduce guesswork
This discussion compares tripeptides, exemplified by the well-studied GHK, with larger peptides such as the cyclic heptapeptide CyRL-QN15, the human cathelicidin-derived antimicrobial peptide LL-37, and the peptide Andersonin W-1 (AW1), containing 7, 37, and 72 amino acids, respectively [25, 67, 68]
The lyophilized presentation helps support peptide stability during storage while providing laboratories with a convenient format for experimental preparation
Scientific Classification A copper-binding tripeptide composed of glycine, histidine, and lysine, supplied as the copper(II) complex
