Research Peptide Comparison
GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) that has attracted considerable research attention for its observed influence on collagen synthesis, matrix metalloproteinase modulation, and wound-healing models in vitro, positioning it primarily as a tissue-remodelling and regenerative research tool. Glutathione, by contrast, is the cell's master antioxidant tripeptide, with research applications centred on redox signalling, oxidative stress mitigation, and the maintenance of intracellular thiol balance. The two compounds therefore represent distinct mechanistic pillars within anti-aging research — structural and reparative on one hand, cytoprotective and redox-regulatory on the other — making their comparison particularly informative for investigators designing multi-target experimental frameworks. Researchers exploring the relative contributions of extracellular matrix renewal versus antioxidant defence in cellular ageing models may find this pairing especially relevant to their study design.
GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) complexed with a divalent copper ion, found endogenously in human plasma at concentrations that decline with age. Research has characterised its capacity to modulate hundreds of genes associated with tissue remodelling, antioxidant defence and extracellular matrix synthesis, with established roles in collagen and glycosaminoglycan production.
Compared to Glow (Glutathione) 70mg, GHK-Cu 50mg is priced at £18.99 with 99%+ verified purity. Its CAS registry number is 49557-75-7. It has a molecular weight of 403.93 g/mol.
GHK-Cu 50mg is available in 50mg, 100mg and ships with a full Certificate of Analysis from Janoshik Analytical. At £41.00 less than Glow (Glutathione) 70mg, it is the more affordable option in this comparison.
Glutathione (GSH) is the predominant intracellular thiol-bearing tripeptide, composed of γ-glutamyl-cysteinyl-glycine, and serves as the master antioxidant and substrate for glutathione peroxidases, S-transferases, and the glyoxalase system. It governs redox homeostasis, phase-II detoxification, and protein S-glutathionylation signalling, making it central to oxidative-stress and longevity research.
Compared to GHK-Cu 50mg, Glow (Glutathione) 70mg is priced at £59.99 with 99%+ verified purity. Its CAS registry number is 70-18-8. It has a molecular weight of 307.32 g/mol.
Glow (Glutathione) 70mg is available in single size and ships with a full Certificate of Analysis from Janoshik Analytical. It is priced £41.00 higher than GHK-Cu 50mg.
