Studies have shown that GHK-Cu at concentrations of 0.01, 1, and 100 nM significantly increased the production of elastin and collagen in human dermal fibroblasts, which are the cells responsible for building skin structure
When the research question specifically isolates these two mechanisms, adding GHK-Cu introduces confounding from its gene-expression and anti-inflammatory effects
Copper peptide serum supports collagen and elastin production, strengthens the skin barrier, calms inflammation, and improves firmness and radiance over time

Among the fatty acids present, tit is comprised of 53% of 18:3 fatty acids, and in decreasing order of concentration, the 16:0, 18:2, 18:1, 16:3+18:0, 16:1, and 16:2
It appears to selectively stimulate GH release without affecting cortisol, prolactin, or aldosterone
