GHK-Cu Peptides (Copper Tripeptide-1) is a naturally occurring copper-binding tripeptide composed of the amino acid sequence glycyl-L-histidyl-L-lysine complexed with copper (II). It is widely studied for its potential roles in tissue remodeling, wound healing, and modulation of inflammatory pathways. Researchers utilize GHK-Cu in preclinical studies to examine its effects on collagen synthesis, angiogenesis, and cellular regeneration. Its unique ability to bind copper ions and influence gene expression makes it a valuable tool for investigations in dermatology, regenerative medicine, and anti-aging research.
