Epithalon
Also known as: Epitalon, Epithalamin, Ala-Glu-Asp-Gly, Tetrapeptide Epithalon
Epithalon is a synthetic tetrapeptide developed from the pineal gland extract Epithalamin by Russian scientist Dr. Vladimir Khavinson. It is one of the most researched longevity peptides, known for activating telomerase and extending telomere length — the molecular hallmarks of cellular aging.

Key Benefits
- Activates telomerase enzyme, extending telomere length
- May slow cellular and biological aging
- Regulates melatonin production and circadian rhythms
- Improves sleep quality
- Powerful antioxidant properties
- May reduce incidence of age-related diseases
- Supports immune system function
- Studied for cancer prevention properties in animal models
Mechanism of Action
Epithalon activates telomerase, an enzyme that maintains and extends telomere length. Telomeres protect chromosomes from degradation and shorten with each cell division — their length is a key biomarker of biological age. Epithalon also regulates the pineal gland, normalizing melatonin production and circadian rhythms. It exhibits antioxidant activity, modulates neuroendocrine function, and has been shown in Russian research to extend lifespan in animal models.
Dosing Protocols
Standard Annual Longevity Protocol
- Dose
- 5–10 mg total per cycle
- Frequency
- 0.5–1 mg daily
- Timing
- Morning, subcutaneous injection
- Cycle
- 10–20 consecutive days, 1–2 times per year
Dr. Khavinson's original protocols used 10-day cycles. Many practitioners do 2 cycles per year. Sublingual delivery also used by some. Allow at least 4–6 months between cycles.

Side Effects
- Injection site irritation (mild)
- Temporary sleep changes during cycle (usually improves)
- Rare: fatigue
Contraindications
Active cancer (theoretical concern — telomerase activation could theoretically support cancer cell proliferation). Pregnancy or breastfeeding.
Storage
Lyophilized powder: store at −20°C. Reconstituted: refrigerate at 2–8°C, use within 30 days.
