What it is
Epitalon is a lab-made four-amino-acid peptide based on epithalamin, an extract from the pineal gland. It was developed by a Russian research group.
It is promoted as an anti-aging peptide because lab studies suggest it may affect telomerase, an enzyme linked to the protective ends of chromosomes.
US regulatory status
Not FDA-approved. In April 2026 the FDA removed it from its Category 2 list of compounding substances with safety concerns, and in July 2026 an FDA advisory committee voted 7-4 to recommend adding it to the list of substances pharmacies may compound. As of October 2026 that recommendation is not final: it still needs FDA rulemaking, a proposed interim access policy was under White House review, and it remains an unapproved drug.
What the research shows
Most research comes from one Russian group and includes cell studies, animal studies and small human reports. These findings have not been confirmed in large, independent trials, and there is no proof it slows aging in people.
