GHK-Cu (Copper Tripeptide-1) is a small peptide–copper complex widely used in cosmetics and research. It is valued for its ability to stimulate collagen, repair tissue, and support hair growth. Below is a structured overview of its key features, technical specifications, and available configurations.

KEY FEATURES 

Biological Role: Naturally occurring peptide in plasma, saliva, and urine; declines with age.

Skin Benefits: Stimulates collagen, elastin, and glycosaminoglycan synthesis; reduces wrinkles and improves elasticity.

Hair Growth: Encourages follicle activity and reduces hair loss in some studies.

Wound Healing: Promotes angiogenesis and tissue regeneration.

Anti-Inflammatory: Modulates gene expression to reduce oxidative stress and inflammation.
