Further investigation revealed a small tripeptide glycyl-L-histidyl-L-lysine (GHK) that appeared to restore regenerative activity in aged tissue samples

For measurement of metabolite levels in the medium, the medium was removed prior to harvesting the hepatocytes and immediately frozen and stored at 80 C for later analysis

New basic and clinical research is clarifying the mechanistic relevance and therapeutic feasibility of multiple targets within the glutamate system for novel drug discovery, including NMDA and AMPA (-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors, metabotropic glutamate receptors, and other key regulatory proteins such as glycine transporter 1 and excitatory amino acid transporters

The reason is partly regulatory: under UK law (specifically the Human Medicines Regulations 2012), peptides marketed for cosmetic or therapeutic use in humans require MHRA authorization, which GHK-Cu currently lacks
