GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK), a sequence first characterized as a naturally occurring copper-binding factor in human plasma.
A natural copper carrier
Researchers found that GHK binds copper with high affinity and that its plasma levels change with age. That copper-binding chemistry — not the peptide alone — is what makes the complex interesting, and it anchors the pathways in its mechanism of action.
Why it is studied
GHK-Cu became a research staple in collagen-synthesis, extracellular-matrix, and gene-expression models — see the GHK-Cu overview. It also appears in combination research such as the GHK-Cu + BPC-157 + TB-500 stack.
