GHK-Cu (Copper Peptide) is a naturally occurring copper-binding tripeptide (Glycine-Histidine-Lysine + Copper) found in human plasma, saliva, and urine. As we age, levels of GHK-Cu decline, which can contribute to slower tissue repair, inflammation, and visible signs of aging.
GHK-Cu has been widely studied for its potent skin remodeling, anti-inflammatory, wound healing, and hair growth effects. It also plays a role in DNA repair, stem cell activation, and collagen synthesis, making it a go-to peptide in aesthetic, regenerative, and anti-aging medicine.
