Epithalon Product Description

Epithalon is a short synthetic peptide built from four amino acids in the sequence Ala-Glu-Asp-Gly. Its structure was modeled on the amino acid composition of Epithalamin, a pineal gland extract studied in gerontology research.

As a defined tetrapeptide, Epithalon is well suited to analytical and mechanistic work. It is supplied as a filler-free lyophilized powder and reconstituted with a sterile solvent immediately before experimental use.

The compound sits within the pineal and AEDG peptide research area, alongside related bioregulator compounds studied for cellular signaling and regulatory function.

Research Applications

Storage and Handling

• Store the lyophilized compound at -20°C, protected from light.
• After reconstitution, store at 2-8°C and use promptly.
• Maintain aseptic handling to preserve compound integrity.

What Research Shows

In telomere-biology research models, Epithalon has been associated with changes in telomerase-associated activity and telomere-length metrics. Cell-line studies have reported telomere-length extension linked to hTERT expression and telomerase upregulation [2]. Comparable telomere-length changes have been observed in lymphocyte models across adult study populations [4].

Epithalon has also been examined for transcriptional effects. In stem-cell models, the AEDG peptide was associated with changes in the expression of neuronal differentiation markers, and molecular-modeling work proposed a histone-interaction mechanism as one possible basis [3].

Within the broader short-peptide literature, AEDG has been studied as a regulator of cell differentiation [5]. A 2025 review consolidates the analytical, in vitro, and in silico characterization of the tetrapeptide reported to date [1].

Researchers studying pineal-linked signaling often examine Epithalon alongside related compounds.

Telomere-Associated Research

Telomere-focused work with Epithalon centers on enzymology and length measurement in cell-based systems. Reported endpoints include telomerase-associated activity, telomere-length metrics, and downstream genome-integrity markers, measured under defined laboratory conditions [2].

Certificate of Analysis (COA) for Every Batch

A Certificate of Analysis (COA) is a document that verifies a compound’s identity, purity, and batch quality through independent laboratory testing. Every compound from BioLongevity Labs ships with a COA tied to its specific batch, so researchers can confirm exactly what they received before it enters a protocol.

Each COA reports results from third-party laboratory analysis, including:

• High-performance liquid chromatography (HPLC) for purity, typically confirmed at 99% or higher
• Liquid chromatography mass spectrometry (LC-MS) for molecular identity and mass confirmation
• Sterility and endotoxin screening where applicable
• Chemical contaminant and residual solvent checks

COAs are sourced from independent certified labs rather than in-house testing alone, giving researchers a verifiable record of molecular integrity for each batch. All compounds are supplied for research use only.
