This one difference is the reason for all the others, from durability to final appearance

GHK-Cu Research Peptide Research Applications GHKCu is used in controlled laboratory systems examining: ECM Biology Matrixassociated signaling and fibroblastlinked pathways CopperDependent Enzymatic Systems Metalloprotein activity and redoxassociated mechanisms OxidativeStress Pathways ROSlinked signaling and antioxidantresponse networks CellularStress Biology Inflammatorymediator regulation and stressresponse gene networks Metallopeptide Signaling Coppertransport mechanisms and peptidemetal interactions Its dual role as a copperbinding peptide and metalion carrier makes GHKCu a valuable tool for studying metalloprotein interactions , ECMassociated pathways , and oxidativestress biology
