GHK-Cu is a naturally occurring peptide (a tiny chain of amino acids) that binds a copper ion. The peptide itself (GHK) exists in human blood and tissues, and when it binds copper (Cu²⁺) it forms the active complex known as GHK-Cu. Its levels are highest in young adults and decline with age.

How It Works (Mechanism)
GHK-Cu acts as a signaling molecule — it influences cell behavior by modulating gene expression, growth factors, and enzymes. Some of its key biological actions include:
-
Stimulating collagen & elastin synthesis — helps strengthen and rebuild extracellular matrix proteins that give skin and connective tissue structure.
-
Regulating growth factors such as TGF-β and VEGF, important for tissue repair and blood vessel formation.
-
Enhancing antioxidant defenses (e.g., boosting enzymes like superoxide dismutase) and reducing inflammatory signaling.
-
Modulating gene expression — research suggests it can influence hundreds or even thousands of genes involved in repair and inflammation.
Think of it as a biological messenger that turns on repair and regeneration pathways with copper acting like a key cofactor.
