GHK-Cu

GHK‑Cu is a naturally occurring tripeptide (Gly‑His‑Lys) that tightly binds to a copper ion. It was first identified in human plasma and later found in saliva and urine.

In the body, it acts as a repair signal — levels are higher in youth and decline with age, which is part of why it’s so heavily studied in regenerative and anti‑aging research.

How it works:

Wound‑healing activation and tissue repair signaling Immune cell attraction to sites of injury
Anti‑inflammatory and antioxidant activity
Stimulation of collagen and glycosaminoglycan synthesis in skin fibroblasts
Promotion of angiogenesis (new blood vessel growth)
Acts as a feedback molecule released after tissue injury to coordinate repair
