Research background

About Epithalon

Epitalon (also written Epithalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by Vladimir Khavinson and the St. Petersburg Institute of Bioregulation and Gerontology as a synthetic analog of a tetrapeptide fraction isolated from bovine pineal gland (Epithalamin). The molecule has been studied since the 1980s for effects on telomerase activity, telomere length maintenance, circadian-rhythm regulation through pineal-melatonin signaling, and broader longevity readouts, making it the canonical Khavinson-class short-peptide bioregulator and the most clinically studied member of the family.

Medabol supplies Epitalon acetate as a lyophilized powder to a ≥99.0% HPLC purity specification. The four-residue sequence is straightforward in SPPS and the analytical packet covers peak-integration HPLC plus mass spec, sequence verification is rarely the critical test for a tetrapeptide. Standard 10 mg, 40 mg and 50 mg fill sizes cover both research aliquot scales and extended-research workflows.

For laboratory research use. This page describes published research and the material we supply; it is not medical advice.

Epithalon FAQ

What is Epitalon's most well-established reported clinical effect?

Epitalon's most consistently reported clinical effect across the Russian research literature is melatonin-pathway modulation and improvement of sleep architecture in older subjects. US regulatory frameworks for the molecule are still developing; Medabol supplies Epitalon strictly for Research Use Only and does not opine on the destination market's specific compounding eligibility — that is the buyer's responsibility.

How to order

Ordering Epithalon from Medabol

Kit and minimum: Epithalon is sold by the kit: 10 vials of one specification (10 mg, 40 mg and 50 mg). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.
Price: Reference prices are listed per kit above, from $52.90. The kits of your whole quote list count together — 5–19 kits are 20% off every kit, and from 20 kits our sales team quotes the price — so Epithalon adds up with anything else you order; your written quote has the final price.
Documents: Every lot has its own COA with HPLC purity and MS identity; the order ships with the certificate of its lot, and our sales team sends it before you order if you ask.
Shipping: Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment: Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal: Listed under Longevity & mitochondria — Mitochondrial peptides, NAD+ and cofactors, and bioregulator peptides.
