GHK-Cu (Copper Peptide)

GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine. Research has shown it to be involved in numerous regenerative processes including collagen synthesis, elastin production, glycosaminoglycan synthesis, and DNA repair. It has seen a 1,016% increase in search interest year-over-year, making it one of the most rapidly growing research peptides of 2026.
