Collagen and extracellular matrix regulation: Multiple in vitro studies have documented the influence of this peptide on fibroblast gene expression, collagen synthesis, and extracellular matrix remodelling

The incorporation of various unnatural amino acid residues into peptides was proven to be a very productive methodology

Combination Research Considerations The mechanistic non-overlap between Epitalon and GHK-Cu suggests potential research value in combination protocols: Upstream + downstream senescence targeting: Epitalon addresses telomere shortening (the upstream trigger of replicative senescence) while GHK-Cu suppresses SASP (the downstream consequence of established senescence) Circadian + antioxidant coverage: Epitalon restores melatonin circadian amplitude
