What is Epithalon?
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide, Ala-Glu-Asp-Gly, originally derived from epithalamin, a polypeptide extract of the pineal gland. Professor Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology have studied it since the 1980s. There is a lot of published work behind it, more than 35 years' worth, though most of it comes from Russian institutions and the trials are mostly preclinical or small.
The mechanism that draws interest: Epithalon appears to stimulate telomerase, the enzyme that maintains and lengthens telomeres, the protective caps on the ends of chromosomes. Telomere shortening is one of the hallmarks of cellular aging, so anything that might slow or reverse it gets attention from longevity researchers.
Effects, what does the research say?
Telomere Elongation
This is the most cited mechanism. Telomeres shorten with each cell division, which is directly linked to cellular senescence and aging. Khavinson's research showed:
- Epithalon activates telomerase in somatic cells (which normally have very low telomerase activity)
- In cell-culture studies, human fibroblasts treated with Epithalon showed measurable telomere elongation
- It activates telomerase in normal cells without the cancer risk usually tied to telomerase activation
"Epithalon peptide induced telomerase activity in human somatic cells in vitro and resulted in elongation of telomere sequences, indicating a potential role in regulating cellular aging."

Melatonin & Pineal Regulation
The pineal gland produces melatonin, which matters for circadian rhythm, sleep quality and antioxidant defence. Pineal function declines with age, which contributes to insomnia and faster aging. Epithalon research shows:
- Restores melatonin production in aged animals whose pineal function has declined
- Normalizes circadian rhythm disruption in aging models
- Strong antioxidant properties, reducing lipid peroxidation
- Studies in elderly patients report improvements in sleep quality
Longevity & Lifespan Extension
Khavinson's long-term animal studies are the part most often cited:
- Multiple rodent studies showed 20-30% lifespan extension with regular Epithalon cycles
- Reduced incidence of spontaneous tumors in treated animals
- Improved immune function and resistance to age-related disease
"Long-term administration of Epitalon to elderly subjects showed a statistically significant decrease in mortality compared with controls, along with biomarker improvements in aging."

Retinal Protection
A less-discussed finding: Epithalon protects retinal cells in animal models, which may be relevant to age-related macular degeneration and other retinal disorders. Treated animals kept more photoreceptor function.
Dosage, what is being researched?
Important: There is no officially approved human dosage for Epithalon. The following reflects what is documented in published research and what longevity research communities report; this is not medical advice.
| Protocol | Dose | Administration | Duration |
|---|---|---|---|
| Standard cycle | 5-10 mg/day | Subcutaneous injection | 10-20 days |
| Maintenance cycle | 5 mg/day | SC or nasal spray | 10 days every 3-6 months |
| Extended longevity | 10 mg/day | SC injection | 10-20 days, 2× per year |
Storage & Reconstitution
- Unreconstituted: Refrigerator (2-8 °C), protected from light, stable up to 24 months
- After reconstitution with bacteriostatic water: max. 30 days refrigerated
- Do not freeze after reconstitution
- Add water slowly along the glass wall, do not shake
