02How They Differ
Epitalon
A synthetic tetrapeptide studied primarily for telomerase activity and chromosomal stability.
Epitalon is a short Ala-Glu-Asp-Gly tetrapeptide modeled on the pineal peptide epithalamin. Its most-studied research property is induction of telomerase (hTERT) expression, with published assays reporting telomere elongation in cultured somatic cells.
NAD+
An essential redox coenzyme and sirtuin cofactor central to cellular energy research.
NAD+ (nicotinamide adenine dinucleotide) is a fundamental coenzyme in redox reactions, cycling between NAD+ and NADH to shuttle electrons through central metabolism. It is the rate-limiting cofactor for the sirtuin family (SIRT1–7) of deacetylases studied in cellular-aging research.

03Selecting for a Research Model
Epitalon (Genomic) and NAD+ (Mitochondrial) occupy different research categories, so the choice usually follows the pathway under study. Selection depends on the research question, model system, and endpoints. Both are supplied strictly for laboratory research and are not for human or veterinary use.
Whichever you select, every Ethos Bio lot is verified the same way — a five-point independent panel with a batch-specific Certificate of Analysis. See how we test →
