Epithalamin: what the evidence says

At a glance

What it is: a polypeptide extract from calf (bovine) pineal gland developed in the Soviet Union by V. Kh. Khavinson's group. It is not the same thing as epitalon, the synthetic four-amino-acid peptide (Ala-Glu-Asp-Gly) later designed from it. R1, R4

What the evidence says: developer-led Russian and Ukrainian studies in older people report lower death rates and changes in melatonin rhythm. Group assignment and controls are poorly described and the findings have not been repeated independently. R1, R2

Biggest risks: not well reported. It is an animal-tissue extract. Unknown

Rating

Human Human evidence Very limited: small developer-led studies in older adults with unclear controls R1, R2
Animal Animal / lab evidence Not rated here (longevity studies in flies, mice, rats reported by the same group R3)
Regulatory Not FDA-approved (no Drugs@FDA record) · Russia: reported as registered in GRLS UNVERIFIED · WADA 2026: not named; S0 depends on Russian registration status UNVERIFIED
Established human dose None recognized outside Russia. Study details lists what studies used where reported

Evidence verdict: Human: Very limited Card verdict: Very limited (aging, developer-led Russian cohorts) Card note: Gray-market "epithalamin" or "epitalon" vials are a different product from the Russian extract in these studies.

About the evidence (developer-led): most of this literature comes from V. Kh. Khavinson's St. Petersburg Institute of Bioregulation and Gerontology and allied Russian, Ukrainian and Georgian groups. Many papers are short, Russian-language, and not independently repeated. Read the findings as the developers' own reports.

What is it?

Epithalamin is a mix of peptides extracted from the pineal gland, the small brain gland that makes melatonin. R1 Researchers later made a synthetic tetrapeptide, epitalon (also spelled epithalon), based on its amino-acid makeup; that has its own page. Results for one should not be assumed for the other. R4

Does it work?

Is it safe?

Gray-market "research use only" Epithalamin: extra risks

Unknown contents. Vials sold online as "research use only" are not made under drug-quality rules, so identity, strength and sterility are unknown. This is a general caution; we have not found independent testing data for this product. Unknown Vendor claims about effects in people are marketing, not evidence. Unknown

What we don't know

Is it legal?

Not FDA-approved (no Drugs@FDA record, openFDA query Oct 25, 2026). Russia: reported as a registered medicine UNVERIFIED, not checked against the Russian State Register of Medicines (GRLS). EU, UK, Japan, China: UNVERIFIED not checked against EMA, MHRA, PMDA or NMPA. WADA: not named on the 2026 Prohibited List; S0 bans substances with no current governmental health-authority approval, which depends on Russian registration status UNVERIFIED.
