What is GHK-Cu (Copper Tripeptide-1 / Glycyl-L-Histidyl-L-Lysine Copper Complex)?

GHK-Cu, also widely known as Copper Tripeptide-1 or Glycyl-L-Histidyl-L-Lysine Copper Complex, is a naturally occurring tripeptide-copper complex discovered in 1973 by Dr. Loren Pickart. Present in human plasma, saliva, and urine, this high-affinity copper-binding peptide plays a key role in modulating over 4,000 human genes, promoting youthful cellular function, and supporting extensive tissue remodeling processes.

In laboratory and biotech research, GHK-Cu peptide is a cornerstone compound for investigating regenerative mechanisms. It stimulates synthesis of essential extracellular matrix proteins such as collagen, elastin, and glycosaminoglycans (including hyaluronic acid), while exhibiting powerful antioxidant, anti-inflammatory, and gene-regulating properties. Levels of natural GHK decline with age, making this copper peptide a focal point in anti-aging research, dermatological studies, and regenerative medicine experiments.
