Epitalon vs NAD+
A field-by-field comparison of Epitalon and NAD+ drawn from the PeptideIndex database: mechanism, evidence grade, half-life, administration route, reported dosing, side effects, storage and legal status. Both are indexed as longevity compounds, so the useful question is how they differ within that category.
Epitalon vs NAD+ at a glance
| Attribute | Epitalon | NAD+ |
|---|---|---|
| Category | Longevity | Longevity |
| Evidence grade | Limited | Emerging |
| Also known as | Epithalon, AEDG peptide | Nicotinamide adenine dinucleotide |
| Chain | Tetrapeptide (Ala-Glu-Asp-Gly) | Coenzyme (dinucleotide, not a peptide) |
| Mechanism | Proposed to induce telomerase reverse transcriptase expression, allowing telomere elongation in somatic cells, and to normalise melatonin rhythm through pineal action. | Serves as an electron carrier in redox reactions and as the required substrate for sirtuins and PARP enzymes, which govern DNA repair and mitochondrial biogenesis. |
| Reported benefits | Telomere lengthening reported in cell culture · Improved sleep–wake rhythm · Longevity signals in long-running Russian cohort studies | Reported energy and mental-clarity improvements · Supports sirtuin-mediated DNA repair pathways · Used adjunctively in recovery clinics |
| Reported side effects | Sparse safety data · Occasional drowsiness · Injection-site reaction | Flushing, chest tightness and nausea during rapid infusion · Injection-site pain · Headache |
| Half-life | Minutes — effects attributed to gene expression rather than plasma level | Very short in circulation |
| Administration | Subcutaneous injection; intranasal versions exist | IV infusion, subcutaneous injection or nasal spray |
| Dosing overview | 5–10 mg daily for 10–20 days, cycled 1–3 times per year | IV 250–750 mg per session; subcutaneous 50–100 mg several times weekly |
| Storage | Reconstituted vials refrigerated and used within the cycle | Refrigerated, light-protected |
| Legal status | Not approved outside of Russia/CIS research contexts. | Compounded and sold in clinics; not an approved drug for ageing. |
Key differences between Epitalon and NAD+
Both are longevity compounds
Epitalon and NAD+ are both indexed under longevity, so they compete for the same use case rather than complementing each other. Epitalon: "A synthetic pineal peptide from Russian gerontology research, studied for telomerase activation and circadian regulation." NAD+: "A central metabolic coenzyme injected or infused in longevity clinics; declining NAD+ is a hallmark of biological ageing."
Mechanism of action
Epitalon: Proposed to induce telomerase reverse transcriptase expression, allowing telomere elongation in somatic cells, and to normalise melatonin rhythm through pineal action. NAD+: Serves as an electron carrier in redox reactions and as the required substrate for sirtuins and PARP enzymes, which govern DNA repair and mitochondrial biogenesis.
Evidence quality is not equal
Epitalon carries a Limited evidence grade and NAD+ a Emerging grade on this index. The grade describes the quality of published human data, not how well a compound works — NAD+ has the better-documented record of the two, and claims made about Epitalon rest on thinner human evidence.
Half-life and dosing frequency
Epitalon is listed at minutes — effects attributed to gene expression rather than plasma level; NAD+ at very short in circulation. That difference is what drives the reported schedules: 5–10 mg daily for 10–20 days, cycled 1–3 times per year versus IV 250–750 mg per session; subcutaneous 50–100 mg several times weekly
Route of administration
Epitalon is administered by subcutaneous injection; intranasal versions exist. NAD+ is administered by iv infusion, subcutaneous injection or nasal spray.
Legal and regulatory status differs
Epitalon: Not approved outside of Russia/CIS research contexts. NAD+: Compounded and sold in clinics; not an approved drug for ageing. This is usually the most practical difference between two compounds, because it determines whether a supply chain is labelled and regulated at all.
Handling and storage
Epitalon is stored reconstituted vials refrigerated and used within the cycle. NAD+ is stored refrigerated, light-protected.
What Epitalon and NAD+ have in common
- Category: both listed as Longevity
Each compound in brief
Epitalon
Longevity · Limited evidence
A synthetic pineal peptide from Russian gerontology research, studied for telomerase activation and circadian regulation.
Considerations: Key studies are decades old and largely unreplicated in the West · Telomerase activation carries a theoretical oncogenic concern · Usually run as short cycles two or three times per year
NAD+
Longevity · Emerging evidence
A central metabolic coenzyme injected or infused in longevity clinics; declining NAD+ is a hallmark of biological ageing.
Considerations: Precursors (NR, NMN) are cheaper and orally available with better human data · Infusions must be run slowly or they are extremely uncomfortable · Benefit in healthy young adults is unclear
