Description

Research Only- GHK‑Cu, also known as Copper Tripeptide‑1 (glycyl‑L‑histidyl‑L‑lysine bonded with a copper ion), is one of the most widely studied bioactive peptides in regenerative and dermatological research. It occurs naturally in human plasma, saliva, and urine, but its concentration declines with age — which correlates with slower tissue repair and reduced skin elasticity
