Research Peptide Comparison
NAD+ (nicotinamide adenine dinucleotide) is a ubiquitous cellular coenzyme that serves as a critical electron carrier in oxidative phosphorylation and a substrate for sirtuin deacetylases, with research interest centred on its role in mitochondrial biogenesis and age-related metabolic decline. SS-31 (Elamipretide) is a synthetic tetrapeptide that selectively concentrates within the inner mitochondrial membrane, where it binds cardiolipin to stabilise cristae architecture and attenuate reactive oxygen species generation at the electron transport chain. While NAD+ augmentation research targets systemic metabolic signalling pathways upstream of mitochondrial function, SS-31 acts directly at the organelle membrane to preserve structural and bioenergetic integrity. Researchers studying mitochondrial dysfunction and cellular senescence may compare these two compounds to investigate whether energy-substrate replenishment and structural membrane protection produce additive or complementary effects in aged cell models.
NAD+ (Nicotinamide Adenine Dinucleotide) is a central pyridine coenzyme that shuttles electrons through oxidative phosphorylation and acts as the obligate substrate for sirtuin deacylases and PARP DNA-repair enzymes. Intracellular NAD+ pools decline with age, and restoring them is one of the most actively investigated levers in mitochondrial and longevity science.
Compared to SS-31 10mg, NAD+ 500mg is priced at £49.99 with 99.2%+ verified purity. Its CAS registry number is 53-84-9. It has a molecular weight of 663.43 g/mol.
NAD+ 500mg is available in 500mg, 1000mg and ships with a full Certificate of Analysis from Janoshik Analytical. It is priced £20.00 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 NAD+ 500mg, 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 £20.00 less than NAD+ 500mg, it is the more affordable option in this comparison.
