- Molecular Class
- Synthetic tetrapeptide (amino acid chain)
- Dinucleotide coenzyme (ribose + nicotinamide + adenine)
- Peptide vs small-molecule biochemistry
- Primary Mechanism
- Activates telomerase (TERT upregulation), extends telomere length in dividing cells
- Electron carrier in redox reactions; sirtuin and PARP substrate
- Chromosomal stability vs bioenergetic flux
- Biological Target
- Telomeres (chromosomal ends), pineal gland epithelial cells
- Mitochondria, nucleus (sirtuins, PARPs), cytoplasm (glycolysis)
- Structural genomics vs metabolic regulation
- Age-Related Decline Addressed
- Telomere shortening, circadian rhythm disruption, replicative senescence
- Mitochondrial dysfunction, NAD+ depletion (≈50% by age 60), impaired ATP synthesis
- Hayflick limit vs bioenergetic insufficiency
- Route of Administration (Research Models)
- Subcutaneous or intraperitoneal injection (water-soluble peptide)
- Oral (NMN, NR precursors), intravenous (NAD+ direct), subcutaneous (rare)
- Peptide stability requires injection; precursors bioavailable orally
- Evidence Base
- Russian gerontology studies (St. Petersburg Institute), limited Western replication
- Extensive mammalian metabolism literature, Phase II human trials (NR, NMN)
- Emerging niche research vs established biochemistry
- Professional Assessment
- Epithalon targets a specific aging hallmark (telomere attrition) with narrow mechanistic focus. NAD+ restoration addresses systemic metabolic decline with broad downstream effects. Not substitutes. Distinct research pathways.
