The "Cu" in GHK-Cu stands for copper, which means it's the copper-bound form of the GHK peptide
This breadth may reflect the fundamental nature of the pathways being studied, such as endothelial function, cell migration machinery, and stress-response biology, rather than a single tissue-specific receptor mechanism
The practical consequence is that the GHK-Cu complex may partially degrade in the presence of high-concentration ascorbic acid on the skin surface, and the free copper(I) could be mildly pro-oxidant
