Epithalon 10mg – Premium Research Peptide

What Is Epithalon?

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide with the amino acid sequence Ala-Glu-Asp-Gly (AEDG), developed as a synthetic analogue of Epithalamin, a polypeptide naturally produced in the pineal gland region. Research has focused on this peptide primarily for its role in telomerase activation and telomere elongation, mechanisms of significant interest in cellular aging and longevity studies.

The peptide was developed in the 1980s by a research team led by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. Unlike its parent compound Epithalamin, which is a crude polypeptide extract, this tetrapeptide is chemically defined and can be synthesized with high purity and consistency. This distinction is critical for research applications, as findings from Epithalamin studies cannot be directly extrapolated to the synthetic analogue.

Research on Epithalon has explored its effects on telomerase activity, gene expression, melatonin regulation, and antioxidant pathways. A pivotal study by Khavinson et al. demonstrated that the peptide induces telomerase activity and telomere elongation in telomerase-negative human fetal fibroblast cultures, suggesting potential for prolonging cellular lifespan.

Research Applications

Telomerase Activation and Telomere Elongation

The most extensively studied mechanism of Epithalon involves telomerase activation. Telomerase is the enzyme responsible for maintaining and extending telomeres, the protective DNA sequences at chromosome ends that shorten with each cell division. According to research published in Springer, the peptide has been shown to increase telomere length in human cell lines through telomerase upregulation or alternative lengthening of telomeres (ALT) activity. This finding was independently replicated in 2025, with telomere extension occurring through hTERT/telomerase upregulation in normal cells.

Pineal Gland and Melatonin Regulation

Epithalon research has explored its effects on pineal gland function and melatonin synthesis. According to in vitro studies, the peptide influences the expression of arylalkylamine-N-acetyltransferase (AANAT) and the transcription factor pCREB in pinealocytes, suggesting a regulatory role in melatonin synthesis. In vivo primate studies have examined its effects on circadian rhythms of melatonin and cortisol in aged subjects.

Gene Expression Modulation

Research using DNA-microarray technology has demonstrated that Epithalon modulates gene expression in mouse heart tissue. According to a study published in PubMed, the peptide activated expression of 194 clones (maximally by 6.61 times) and inhibited expression of 48 clones (maximally by 2.71 times), demonstrating specific effects on gene expression.

Antioxidant and Neuroendocrine Effects

Preclinical studies have reported age-dependent neuroendocrine effects and antioxidant-associated activity for Epithalon. In female mice, the peptide did not increase mean lifespan but increased maximum lifespan by 12.3%. Research has also explored its effects on interleukin-2 concentration in hypothalamic structures.

Frequently Asked Questions

What is Epithalon?

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed as a synthetic analogue of Epithalamin, a pineal-derived polypeptide. It is studied primarily for its role in telomerase activation and cellular aging research.

How does it work?

The peptide is studied for its ability to induce telomerase activity and elongate telomeres in human somatic cells. Telomerase maintains telomere length, supporting continued cell division and the replacement of aging cells.

What is the molecular weight?

Epithalon has a molecular weight of approximately 390.35 g/mol.

What purity level can I expect?

Our product is provided at ≥99% purity, verified by HPLC.

How should it be stored?

The peptide should be stored at -20°C for long-term stability. Lyophilised powder should be reconstituted according to standard laboratory protocols.

Is it FDA-approved?

Epithalon is not FDA-approved as a medicine. The FDA reviewed Epithalon free base and acetate through the 2026 PCAC compounding process, which does not constitute therapeutic approval. FDA has stated there are no clinical data to support the safety of this peptide when used in humans.

What is the regulatory status?

Epithalon is classified as a research chemical in the United States. While the FDA’s Pharmacy Compounding Advisory Committee voted in favor of the peptide for potential inclusion on the 503A Bulks List in July 2026, this recommendation is advisory only and does not change current legality. FDA rulemaking is required before compounding is permitted.

What dosage is available?

Our product is available in 10mg per vial, providing sufficient material for extended research protocols.
