GHK-Cu

GHK-Cu, also known as Copper Peptide or Glycyl-L-histidyl-L-lysine Copper, is a naturally occurring tripeptide complex that includes the amino acids glycine, histidine, and lysine, bound to a copper ion. It was first identified in human plasma and has since been synthesized for research purposes. The compound is known for its blue color due to the presence of copper and is typically synthesized through solid-phase peptide synthesis techniques. Researchers have extensively studied GHK-Cu for its potential applications in anti-aging and skin health. It has been observed to promote wound healing, reduce inflammation, and improve skin elasticity and firmness. Additionally, GHK-Cu has been investigated for its role in hair growth and its potential to reduce fine lines and wrinkles. The mechanism of action of GHK-Cu involves its ability to bind to copper ions, which plays a crucial role in activating various biological processes. Researchers have found that it can influence the expression of a wide range of genes related to tissue remodeling, antioxidant defense, and anti-inflammatory responses. Pharmacokinetic studies of GHK-Cu indicate that it has a relatively short half-life, with stability influenced by its formulation and route of administration. Its bioavailability varies, with topical applications being the most common due to its poor oral bioavailability. Current research on GHK-Cu is ongoing, with studies exploring its broader therapeutic potential. It is not approved as a medicinal product by major regulatory agencies, and its use is primarily limited to research and cosmetic applications.
