Epithalon (Epitalon)
Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on epithalamin, a natural peptide produced by the pineal gland. It is the most studied peptide in the field of telomere biology and aging. Research by Professor Vladimir Khavinson demonstrated that epithalon activates telomerase, the enzyme responsible for maintaining telomere length at the ends of chromosomes. Telomere shortening is one of the hallmarks of cellular aging, and preserving telomere length is a central target of longevity science.

Its job is to frame benefits, dosing, evidence strength, sourcing, and safety boundaries in one place, especially where the search overlaps with peptide therapy. A useful reader should leave with better questions about clinician oversight, evidence quality, safety limits, cost, pharmacy path, and what changes for their own health history.
- Confirm whether the page is discussing approved care, compounded access, off-label use, or research-only context.
- Check the date, evidence quality, safety limits, and whether newer clinical or regulatory updates may change the answer.
- Ask a licensed clinician how the information applies to your history, medications, labs, goals, and risk profile.

Step 1
Check evidence level
Epithalon (epitalon) comes from decades of research by Russian scientist Vladimir Khavinson on pineal gland peptides. The most cited finding is telomerase activation in human cell cultures. A few small Russian clinical studies report improved biomarkers in elderly subjects, but these studies have limited methodology by Western standards. The science is interesting but needs replication in larger, well-controlled trials.

About Epithalon
Epithalon (also spelled epitalon or epithalone) is a tetrapeptide with the sequence Ala-Glu-Asp-Gly. Molecular weight: 390.35 Da. CAS number: 307297-39-8. It's a synthetic version of epithalamin, a peptide extract from the pineal gland first studied by Russian gerontologist Vladimir Khavinson beginning in the 1980s.
The most frequently cited finding about epithalon is its ability to activate telomerase, the enzyme that maintains telomere length. A 2004 study in the Bulletin of Experimental Biology and Medicine (PMID: 15452597) showed that epithalon activated telomerase in human fibroblast cultures and allowed cells to continue dividing beyond the normal Hayflick limit (the point where cells stop replicating). In animal models, epithalon extended lifespan in fruit flies by 11-16% (PMID: 14602072).
Khavinson and colleagues published numerous studies on pineal peptides in Russian journals over several decades. Some of these reported improved neuroendocrine function, better sleep, and normalized melatonin production in elderly subjects receiving epithalon injections. The challenge is that many of these studies were small, conducted in Russia, and published in journals with limited peer review by Western standards.
The typical protocol is 5-10 mg injected subcutaneously daily for 10-20 days, repeated 1-2 times per year. This pulsed dosing approach comes from Khavinson's original protocols. Some practitioners use lower doses (2-3 mg daily) for longer durations.
The connection between epithalon and melatonin is worth understanding. The pineal gland produces melatonin, and its output declines with age (pineal calcification). Epithalon appears to stimulate pineal function, potentially restoring some melatonin production. This could explain the sleep improvements reported in the Russian studies without directly proving an anti-aging effect.
Epithalon is typically used alongside other anti-aging peptides like GHK-Cu, NAD+, and MOTS-c. The longevity peptide community views it as one piece of a broader protocol, not a standalone treatment.
Store lyophilized epithalon at -20C. It's a small, stable peptide that reconstitutes easily. Use bacteriostatic water and store reconstituted vials at 2-8C.
How Epithalon Works
Epithalon activates the catalytic subunit of telomerase (hTERT) in somatic cells, enabling the addition of telomeric repeats to the ends of chromosomes. This counteracts the progressive telomere shortening that occurs with each cell division and is associated with cellular senescence. Epithalon also stimulates melatonin production from the pineal gland, helps normalize circadian rhythm, and has demonstrated antioxidant properties by upregulating superoxide dismutase and other protective enzymes.
