Research Peptide Comparison
Glutathione is the most abundant endogenous tripeptide antioxidant in mammalian cells, functioning as the primary cytosolic redox buffer via its thiol group and serving as a cofactor for glutathione peroxidases that neutralise hydrogen peroxide and lipid peroxides. SS-31 (Elamipretide) is a synthetic aromatic-cationic tetrapeptide that partitions into the inner mitochondrial membrane to bind cardiolipin, scavenging mitochondria-localised reactive oxygen species and preventing the conversion of cytochrome c into a peroxidase. Where glutathione provides broad-spectrum cytosolic and aqueous-phase antioxidant protection, SS-31 delivers compartment-specific, membrane-anchored defence within the mitochondrial matrix. Researchers investigating oxidative stress aetiology may compare these compounds to dissect the relative contributions of cytosolic redox buffering versus organelle-targeted antioxidant intervention in models of cellular ageing or metabolic stress.
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 SS-31 10mg, 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 £30.00 higher than SS-31 10mg.
SS-31 (Elamipretide) is a synthetic aromatic-cationic tetrapeptide that selectively concentrates in the inner mitochondrial membrane and binds cardiolipin, stabilising cristae architecture and supporting electron-transport chain efficiency. It is a leading mitochondria-targeted research compound in models of ischaemia-reperfusion injury, heart failure, and age-related mitochondrial decline.
Compared to Glow (Glutathione) 70mg, SS-31 10mg is priced at £29.99 with 99%+ verified purity. Its CAS registry number is 736992-21-5. It has a molecular weight of 640.75 g/mol.
SS-31 10mg is available in 10mg, 50mg and ships with a full Certificate of Analysis from Janoshik Analytical. At £30.00 less than Glow (Glutathione) 70mg, it is the more affordable option in this comparison.
