GHK-Cu 100 mgCopper tripeptide

GHK-Cu 100 mg is a small three-amino-acid peptide (glycine, histidine, lysine) bound to a copper ion. It occurs naturally in plasma, saliva and urine, and its level drops with age: about 200 ng/mL at age 20 versus 80 ng/mL at age 60. It is widely used in cosmetics (creams and serums) and studied for tissue repair.

GHK-Cu: studied effects

• More collagen and elastin made by the skin
• Firmer skin and fewer fine lines in cosmetic studies
• Faster wound healing
• Antioxidant and anti-inflammatory effects
• Support of hair follicle growth seen in the lab

What the research says

GHK-Cu was discovered in 1973 by researcher Loren Pickart. Clinical studies mostly cover its use on the skin, where it improved skin density and elasticity and reduced wrinkles compared with placebo. Data on injection in humans are limited, and injection-site reactions (redness, a burning feeling) are sometimes reported.
