Investigators have proposed that GHK-Cu's central function is to deliver copper to fibroblasts in a controlled, non-toxic form buffering against the redox damage that free Cu would otherwise cause [4]
GHK-Cu 100mg (10 vials) is a laboratory research peptide used to study peptide-copper interactions, signaling pathways, and cellular-response patterns in controlled experimental systems
While generally well-tolerated in research settings, comprehensive human safety data is lacking
