- Primary Mechanism
- Activates telomerase (TERT enzyme) to lengthen telomeres at chromosome ends
- Fuels mitochondrial ATP production and activates sirtuin proteins (SIRT1–7) for DNA repair
- Non-overlapping pathways. One addresses replicative aging, the other metabolic aging
- Measurable Biomarker
- Telomere length (measured via qPCR or flow-FISH). 33% increase demonstrated in published trials
- Intracellular NAD+/NADH ratio and mitochondrial respiration rates. 60% NAD+ increase with precursor supplementation
- Both produce quantifiable changes, but telomere testing is less accessible than metabolic panels
- Optimal Application
- Replicative senescence prevention in immune cells, vascular endothelium, and stem cell populations
- Energy deficiency, cognitive decline, metabolic dysfunction, exercise recovery
- Use epithalon for cellular aging; NAD+ for functional decline
- Administration Route
- Subcutaneous injection (typical protocol: 5–10mg daily for 10–20 days, cycled every 3–6 months)
- Oral precursors (NR/NMN 250–1000mg daily) or IV infusion (500–1000mg weekly)
- Epithalon requires injection cycles; NAD+ allows daily oral dosing
- Evidence Depth
- 40+ peer-reviewed studies, primarily from Russian gerontology institutes. Limited independent replication
- 200+ studies across multiple institutions globally. Broader research base but mixed clinical outcomes
- NAD+ has more institutional backing; epithalon has longer observational follow-up
- Cost Comparison (2026)
- $80–$150 per 10-day cycle (research-grade peptide from 503B facilities)
- NR/NMN supplements: $40–$80/month; IV NAD+: $200–$400 per session
- Epithalon is episodic cost; NAD+ is ongoing monthly expense
