Collagen signaling with copper delivery.
GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) bound to copper — studied for effects on collagen synthesis, antioxidant activity, and skin barrier repair in cell and animal models.
It is widely used in topical skincare but also discussed for injectable protocols. Natura pre-fills it so you skip reconstitution and can verify peptide content and copper ratio on the COA before dosing.
