GHK-CU

What is GHK-Cu?

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper peptide found in human plasma, saliva, and urine. First identified in the 1970s, GHK-Cu has become one of the most widely studied peptides in regenerative and dermatological research. This tripeptide-copper complex has drawn significant interest from researchers investigating wound repair, tissue remodeling, and extracellular matrix regulation in preclinical models.

GHK-Cu Research Background

GHK-Cu was originally isolated from human albumin and identified as a growth-modulating factor in laboratory studies. The peptide binds copper(II) ions with high affinity, forming a stable complex that has been examined across numerous preclinical investigations. Research has demonstrated that GHK-Cu modulates the expression of a wide range of genes involved in tissue repair processes, positioning it as a compound of considerable interest in regenerative biology and cellular signaling research.

In laboratory settings, GHK-Cu has been characterized for its ability to influence collagen synthesis, glycosaminoglycan production, and metalloproteinase activity. These documented properties have made GHK-Cu a key subject in studies exploring extracellular matrix remodeling, fibroblast proliferation, and copper-dependent enzymatic pathways.

GHK-Cu Mechanism of Interest

GHK-Cu is believed to promote the activation of genes involved in collagen synthesis, angiogenesis, anti-inflammatory response, and antioxidant defense. The copper peptide complex supports cellular repair mechanisms by enhancing extracellular matrix production and modulating immune responses in tissue injury models. Researchers have also noted its role in stimulating decorin production and regulating growth factor expression in fibroblast and keratinocyte cultures.
