GHK-Cu is a complex of copper and glycyl-l-histidyl-l-lysine (GHK), a peptide present in human plasma, saliva, and urine that decreases in concentration as we age

Because so much of GHK-Cus activity is copper-mediated, it is difficult in some experiments to separate specific tripeptide signaling from generic copper effects a point made concrete by the finding that the MMP-2 effect was reproduced by copper ions alone while the collagen-synthesis effect required the intact peptide

However, another mechanism may be that the pentadecapeptide BPC 157 can directly protect against paracetamol induced brain damage

In mammalian cells, it triggers mitochondrial membrane disruption and cytochrome C release, subsequently inducing cell apoptosis 49,50
