Backed by over 50 years of published research, GHK-Cu is the most scientifically studied copper peptide in dermatological literature, with documented effects on collagen synthesis, extracellular matrix remodeling, and wound repair pathways

The limiting factor often isn't fitness

GHK-Cu peptide is also apparently active as a matrikine, potentially recruiting repair-associated cells and promoting angiogenesis

Thus, GSH participates as a co-factor in several reactions, including the elimination of peroxides by GSH peroxidases (GPx), the covalent addition to protein cysteines (Protein-SSG) predominantly performed by glutaredoxin, and the detoxification of electrophiles by S-glutathionylation (GS-R) formation as catalyzed by the enzymes glutaredoxin and glutathione S-transferase (GST) [4,11,12]
