What the molecule is, where the sequence comes from, and what it binds. This page does not describe what GHK-Cu does.
Structure
What GHK-Cu is
Origin. The tripeptide glycyl-L-histidyl-L-lysine, first isolated from human plasma, supplied as its copper(II) complex.
Molecular target. Characterised by its high affinity for copper(II), which it coordinates through the histidine imidazole and the terminal amine.
Both statements are facts about the molecule and can be checked against any reference database. Neither is a statement about an outcome, and this page makes none.
