In published preclinical research, GHK-Cu has been examined across in vitro fibroblast and keratinocyte cultures (PMID 19319546, PMID 23019153), murine wound-healing and tissue-remodelling models (PMID 38879894, PMID 39902373), and broader gene-expression-profiling work in cell culture (PMID 28212278, PMID 29986520)
