GHK-CU

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. First identified in the 1970s, it has since become one of the most extensively researched peptides in regenerative biology, wound healing, and skin remodeling — with a uniquely broad mechanism that influences gene expression across hundreds of biological pathways.

GHK-Cu acts as a potent modulator of gene expression, upregulating genes associated with tissue repair, collagen and elastin synthesis, and antioxidant defense, while downregulating pro-inflammatory and cancer-promoting genes. Its copper chelation also plays a key role in enzymatic activity central to connective tissue remodeling.
