In this study, we evaluate the SL and KAR recognition ability of ShHTLs and ShD14 in vitro and determine the crystal structures of different clades of ShHTLs and ShD14, providing structural insights into the evolution of their SL/KAR selectivity based on a comprehensive structural comparison

Storage duration critically impacts effectiveness - reconstituted GHK-Cu lasts only 21-28 days refrigerated due to copper oxidation concerns (shorter than most peptides), requiring strategic reconstitution of amounts usable within this window rather than preparing entire vials at once
