Epithalon

Telomere Lengthening Studies

Epithalon is a peptide made of four amino acids. It comes from epithalamin, a pineal gland extract studied in the Soviet Union. Studies have measured telomerase activity and telomere length in cultured human cells. Sleep-wake timing has been examined in animal models. At four amino acids, it is one of the shortest active sequences in the research literature.

How it works

Telomerase

Telomerase Activation & Telomere Biology

In cultured human somatic cells, Epithalon has been reported to induce expression of the telomerase catalytic subunit (hTERT) and elongate telomeres, extending the proliferative capacity of the cultures in preclinical models.

  • Induction of hTERT expression in vitro
  • Telomere elongation in cultured fibroblasts
  • Extended proliferative lifespan of cell cultures
Pineal / Circadian

Pineal Peptide Signaling

Modeled on the pineal gland peptide epithalamin, Epithalon has been studied for its influence on melatonin secretion rhythm and circadian regulation in rodent models of aging.

  • Based on the natural pineal peptide epithalamin
  • Studied for melatonin secretion rhythm
  • Circadian regulation in animal models
Gene Expression

Chromatin & Antioxidant Regulation

Preclinical work reports that Epithalon can interact with DNA and modulate expression of genes associated with cellular senescence and antioxidant activity in animal tissue.

  • Proposed peptide–DNA interaction
  • Modulation of senescence-associated genes
  • Antioxidant enzyme expression in vitro

Frequently asked questions

What is Epithalon?

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on epithalamin, a peptide isolated from the pineal gland. It has been studied primarily in gerontology research for telomerase activation and pineal/circadian biology in cell-culture and animal models.

Is Epithalon FDA approved?

No. Epithalon is not approved by the FDA or any regulatory agency for human use, and it is not a drug, supplement, or therapeutic product. It is supplied strictly as a reference compound for in-vitro laboratory research.

How should Epithalon be stored?

Store the lyophilized powder at −20°C or colder, protected from light, through the period indicated on the Certificate of Analysis. This is storage guidance for the researcher, not a shipping requirement.

What purity is this Epithalon?

Each lot is ≥99% pure by HPLC with identity confirmed by mass spectrometry, and ships with a third-party Certificate of Analysis documenting purity, net peptide content, and endotoxin screening.
