GHK-CU
GHK-CU
GHK-Cu is a tiny copper peptide found naturally in the body. It's best known for skin health — collagen, firmness, wound healing — and it also influences a huge number of genes related to repair and aging.
How GHK-CU Works
A deeper look for the curious
For readers who want the full mechanism — feel free to skim.
GHK-Cu is a tiny three-amino-acid peptide that carries one copper atom — a combination that naturally exists in the body and drops off sharply with age. It influences more than 4,000 genes related to repair, collagen production, antioxidant defense, and skin renewal.
