Copper-binding tripeptide
GHK-Cu
Gly-His-Lys copper complex studied for gene-expression, remodelling, and antioxidant effects in skin and tissue-repair models.
Primary Mechanism of Action
Clinical / Scientific
GHK has high affinity for Cu2+. The complex has been reported to modulate expression of genes involved in matrix remodelling, antioxidant enzymes, and in cultured cells and cosmetic/research settings. It is not a systemic licensed disease therapy.
Pathway Targets
Copper-dependent enzymes / transcription
Scientific explanation
Reported broad gene-expression shifts in models.
Extracellular matrix remodelling
Scientific explanation
Collagen/elastin-related research readouts.
Pathway Convergence
Clinical / Scientific
Target → pathway → downstream effect → biological consequence. This is a mechanistic map, not a treatment claim.
Receptor to physiology
Target to downstream effect: Copper-dependent enzymes / transcription → Extracellular matrix remodelling

In Plain Language
GHK-Cu is a tiny copper-carrying peptide studied mostly for skin and repair gene switches, not as an approved internal drug.
