The peptide complex restores extracellular matrix homeostasis by increasing the synthesis and turnover of collagen, elastin, and glycosaminoglycans, as well as by modulating the balance between metalloproteinases (MMPs) and their inhibitors (TIMPs), thus supporting both matrix remodeling and scar resolution 2,3

When in doubt about solution age or condition, reconstitute fresh

The concentration was far below standard GHK-Cu serums (0.02% vs 1 to 2%)

Levels decline with age and drop further in chronic disease, including Parkinson's disease, liver disease, heart disease, and alcohol use disorder
