GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a tripeptide-copper complex naturally present in human plasma, saliva, and urine. It has been extensively studied in preclinical research for its roles in tissue remodeling, extracellular matrix synthesis, angiogenesis, and antioxidant defense mechanisms. GHK-Cu is among the more thoroughly characterized research peptides with a well-established preclinical literature base. Supplied by Helix Strand Labs in lyophilized form for in-vitro and laboratory research applications only.
