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]
Laboratories set their own reference ranges based on their methods
TB-500, a synthetic fragment corresponding to the active region of the endogenous peptide Thymosin Beta-4, drives the cellular migration phase of repair by sequestering G-actin, promoting cell motility, and mobilising stem and progenitor cells to sites of tissue disruption
