GHK-Cu
Copper Peptide GHK
GHK-Cu (glycyl-L-histidyl-L-lysine with a copper(II) complex) is a naturally occurring tripeptide detected in human plasma, saliva and urine. It binds copper ions and transports them into tissue. In vitro and in preclinical models, effects on collagen synthesis, antioxidant enzyme activity and the expression of growth factors (including VEGF, FGF) have been described. The precise mechanism of action in vivo in humans has not been fully elucidated.
AHK-Cu
AHK-Cu
AHK-Cu is a copper-binding tripeptide (alanine-histidine-lysine) and belongs to the family of cosmetic copper peptides, similar to the better-known GHK-Cu. The bound copper ion is considered functionally relevant. In preclinical investigations AHK-Cu has been described mainly in the context of hair-follicle stimulation and promotion of dermal cells. Use is predominantly topical/cosmetic.
