GHK-Cu is studied across preclinical tiers because its copper-binding chemistry touches several distinct cellular pathways.
In-vitro research
Cell models — often fibroblast cultures — are used to study collagen and extracellular-matrix synthesis, and gene-expression changes, at defined in-vitro concentrations. The copper complex, not the peptide alone, drives much of this activity — see its mechanism of action.
Animal-model research
Animal models explore dermal-remodeling and tissue-response endpoints in controlled settings. For the wider context see the GHK-Cu overview and its skin and collagen applications.
