GHK-Cu — Copper(II)-Tripeptide Complex
GHK-Cu (Glycyl-L-histidyl-L-lysine · Cu²⁺) is a copper complex of a tripeptide naturally occurring in human plasma, first identified in 1973. It is one of the most extensively characterized peptides in the scientific literature, with thousands of publications on its role in laboratory models of gene expression, collagen synthesis, antioxidant activity and extracellular matrix biology.
What it is studied for
In the published preclinical literature, GHK-Cu has been investigated in laboratory and in-vitro models for its effects on:
- Skin quality & collagen — synthesis of collagen, elastin and glycosaminoglycans
- Wound healing & regeneration — tissue remodelling in repair models
- Anti-ageing gene expression — broad reset of gene-expression profiles toward a healthier state
- Antioxidant & anti-inflammatory activity — reduced oxidative and inflammatory markers
- Hair growth — follicle stimulation in dermatological models
In plain terms: one of the most studied peptides for skin remodelling, collagen and regeneration.
