GHK-Cu is most closely associated with dermal and connective-tissue research, where its copper-binding chemistry intersects with collagen and matrix biology.
Collagen and matrix synthesis
A large share of GHK-Cu research examines collagen production and extracellular-matrix remodeling in fibroblast models, studying how the copper complex influences the proteins that give tissue its structure.
Gene-expression signaling
Other work looks at broader gene-expression changes associated with the peptide in cell models, part of why it is studied as a remodeling-related compound rather than a single-pathway one — see its mechanism of action.
In combination research
GHK-Cu also appears in blends such as the GHK-Cu + BPC-157 + TB-500 stack; see peptide blends and research stacks and its discovery and history.
