Copper is an essential cofactor for many biochemical processes, and binding it to GHK creates a peptide-copper model for laboratory study
Wound healing research with GHK-Cu encompasses numerous preclinical models
Traditional cell lines cannot adequately recapitulate intratumoral heterogeneity, whereas patient-derived organoids, xenografts, and ex vivo co-culture systems only partially reproduce immune, stromal, vascular, and microbial interactions

These help control oil production whilst supporting the skin-brightening effects of glutathione
Mechanistically, Epitalons effect appears to involve a direct interaction with promoter regions of the telomerase gene, where it binds specific DNA sequences (such as ATTTC motifs), potentially modulating transcriptional activity
