GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding peptide found in small amounts in the human body, particularly in blood plasma, saliva, and urine. Levels tend to decline with age.
It has been studied for its potential role in:
Skin repair and anti-aging: May stimulate collagen and elastin production, helping improve skin firmness and reduce the appearance of fine lines.
Wound healing: Research suggests it may promote tissue repair and reduce inflammation.
Hair growth: Some studies indicate it may help improve hair density in certain types of hair loss.
Antioxidant effects: May help protect cells from oxidative stress.
Nerve and tissue regeneration: Early research suggests possible benefits, but more human studies are needed.
