GHK-Cu is a tiny peptide of three amino acids joined to copper. Small amounts occur naturally in blood and skin. It is widely used in skin creams, and a separate injectable form is sold.
Skin creams have a long track record. For injection, research is only in animals and the lab. No human study has tested an injected dose.

This is the injectable schedule circulating in this market, rising over 12 weeks. No human trial has tested any injected dose. The 28-day column assumes 3 injections a week. Skin products use 0.5 to 2 percent creams instead.
