The copper peptide
GHK-Cu
Skin structure research
What it is
GHK is a short chain of three amino acids: glycine, histidine and lysine. It binds copper to form GHK-Cu. The “Cu” is the chemical symbol for copper.
Why it interests us
Researchers study GHK-Cu for its effects on collagen production and the supporting material around skin cells. Collagen is one of the proteins that gives skin its structure.
Look at the research
A 1988 laboratory study found increased collagen synthesis in fibroblast cultures exposed to GHK-Cu. Fibroblasts are cells involved in making the skin’s supporting matrix. This was a cell-culture experiment, not a trial of body patches.
