Buy Epitalon 10mg (Epithalon) — Ala-Glu-Asp-Gly Research Peptide

Epitalon (also spelled Epithalon; AEDG peptide) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly [R1]. It was designed from the amino-acid composition of epithalamin, a polypeptide extract of the bovine pineal gland, and proposed as one of its active components [R2]. Published research has examined epitalon in cell-culture models of telomerase and gene expression, and in rodent and primate models of aging and pineal function [R3]–[R7]. Most of that work comes from one research group, and recent reviews describe the compound as biologically active but clinically unproven [R2][R8].

1. Epitalon Research Overview

   Telomerase and telomeres

   In a 2003 study, epitalon increased expression of the telomerase catalytic subunit, telomerase activity, and telomere length in cultured human fetal fibroblasts [R3]. An independent 2025 study in human cell lines reported telomere elongation in normal cells through telomerase upregulation but in breast-cancer cell lines through the telomerase-independent ALT pathway [R9]. That paper was later corrected.

   Rodent aging models

   In female SHR mice, epitalon did not change mean lifespan or total tumor incidence, though some secondary measures differed from controls [R4]. In rats, effects on lifespan depended on the light regime and were absent under a standard light/dark cycle [R5].

   Pineal and circadian studies

   In a small study of senescent rhesus monkeys (three animals per group), epitalon was associated with higher evening melatonin levels; no effect was seen in young animals [R6].

   Gene expression

   In human gingival mesenchymal stem cells, epitalon increased mRNA of neurogenesis markers (Nestin, GAP43, β-Tubulin III, Doublecortin) by 1.6–1.8-fold; proposed histone binding was modeled computationally, not measured [R7].

   Limits of the evidence

   Nearly all studies come from the St. Petersburg Institute of Bioregulation and Gerontology. Sample sizes are small, several results are null or condition-dependent, no pharmacokinetic study exists in any species, and no adequately powered randomized human trial has been published [R2][R8].

   Regulatory Status

   Epitalon is not approved by the FDA for any use. In July 2026, an FDA advisory committee narrowly voted to recommend it for the 503A bulk-substances list for compounding; the vote is non-binding, and FDA had not changed the list as of October 2026 [R10][R11].

   Epitalon FAQ

   What is epitalon?

   Epitalon is a synthetic four-amino-acid peptide (Ala-Glu-Asp-Gly), CAS 307297-39-8, studied in laboratory models of telomere biology, gene expression, and pineal function [R1][R2].

   Is epitalon the same as epithalon?

   Yes. Epitalon and Epithalon are two spellings of the same synthetic tetrapeptide. Epithalamin is different: it is the pineal-gland extract that epitalon was designed from [R2]. See our full guide: epitalon vs epithalon vs epithalamin.

   Does epitalon lengthen telomeres?

   Some cell-culture studies report telomere elongation in human cells [R3][R9]; in cancer cell lines it occurred through the ALT pathway rather than telomerase [R9]. No controlled human study has shown it.

   Is epitalon FDA-approved?

   No. It is not an approved drug. A July 2026 advisory committee vote on compounding was non-binding and has not changed its status [R10][R11].

   How should epitalon be stored?

   Store the lyophilized powder at −20 °C, protected from light and moisture. Follow the batch COA for solution handling.

   Can epitalon be used by humans?

   No. Sequora supplies epitalon as a research chemical for in-vitro and laboratory use only.

   Epitalon is listed in our Bioregulators category.
