Epithalon Research Overview: Pineal Tetrapeptide, Telomerase Studies, and Lab Handling

For in-vitro and laboratory research only. The literature summarized below is preclinical and limited; no claims of effect in humans are made or implied.

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It was developed in the Saint Petersburg Institute of Bioregulation and Gerontology as a synthetic analog of epithalamin, a pineal-gland peptide fraction. The peptide has been studied for decades primarily by Russian research groups, with a smaller body of independent replication. Available as Epithalon 10mg lyophilized.

Structure

Epithalon’s sequence is Ala-Glu-Asp-Gly (AEDG). Molecular weight is approximately 390 Da, making it among the smallest research peptides commonly sold.

Mechanisms reported in published literature

• Telomerase modulation. Published cell-culture work reports upregulation of telomerase activity in somatic cell lines treated with Epithalon, with extended replicative lifespan of fibroblasts in some protocols.
• Pineal-axis interaction. Rodent studies have reported normalization of melatonin secretion patterns in aged animals, the most-cited mechanistic claim.
• Gene expression. Cell-culture papers describe changes in expression of genes involved in cellular senescence and DNA repair.

Research note: Much of the Epithalon literature is from a single research group. Independent replication is limited. Researchers should weight published claims accordingly.

Common research-model applications

• Cellular senescence and replicative-lifespan models in fibroblasts
• Telomerase-activity assays in immortalized and primary cell lines
• Rodent aging-cohort studies measuring melatonin secretion patterns

Handling and storage

Epithalon is supplied lyophilized. Standard peptide storage practice applies — sealed at −20°C protected from light and moisture — see our peptide storage guide. The tetrapeptide structure is relatively stable, with reported lyophilized shelf life of 24+ months under proper conditions.

For research workflows, reconstitution in bacteriostatic water is standard. The small molecular weight means concentration math is straightforward.

Related peptides

Epithalon is sometimes discussed alongside other short bioregulator peptides developed by the same research school, including Pinealon (a three-residue pineal-derived peptide). The two are structurally distinct and the published literature for one does not transfer cleanly to the other.

What to verify on the COA

• Sequence: Ala-Glu-Asp-Gly. Confirm the order — the related peptide Vilon (Lys-Glu) and the longer "PRE-7" peptides have similar branding but different chemistry.
• Purity ≥98% by HPLC.
• Mass spec match for ~390 Da.
