Activation of Tissue Remodeling Proteases GHK-Cu activates matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) in a balanced way that facilitates controlled extracellular matrix remodeling breaking down damaged collagen and replacing it with new, organized fibrillar collagen rather than scar tissue
The characteristic dark blue color of properly reconstituted GHK-Cu solution provides a visual confirmation that the copper-peptide bond is intact and the reconstitution is successful

So the peptide is not just present it is active in processes people actually care about when they are trying to look better, heal better, or age a little less visibly
