What is Epithalon?

Epithalon (also known as Epitalon or epithalamin) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by Vladimir Khavinson at the Saint Petersburg Institute of Bioregulation and Gerontology in Russia. Its primary mechanism of action involves activation of telomerase, the enzyme responsible for adding telomeric repeats (TTAGGG) to chromosome ends, thereby counteracting the progressive telomere shortening associated with cellular aging. Published research by Khavinson and colleagues (Bulletin of Experimental Biology and Medicine, 2003) demonstrated that epithalon increased telomerase activity in human somatic cells and extended the replicative lifespan of fibroblast cultures beyond the Hayflick limit. In animal studies, chronic epithalon administration in aging rats was associated with increased lifespan and restoration of melatonin secretion rhythms from the pineal gland, which naturally declines with age (Anisimov et al., Mechanisms of Ageing and Development, 2003). The peptide also appears to modulate expression of genes involved in antioxidant defense and circadian rhythm regulation. Compared to other telomerase activators such as TA-65 (a small molecule derived from astragalus), epithalon is a direct peptide bioregulator with a well-characterized tetrapeptide sequence. Research also suggests potential effects on retinal health, with studies indicating photoreceptor preservation in aging retinal models. Store lyophilized powder at -20C protected from moisture; reconstitute with bacteriostatic water and refrigerate at 2-8C for up to 21 days. Epithalon is studied by gerontology research centers, telomere biology laboratories, and chronobiology departments investigating age-related decline in pineal gland function.

Epithalon Research Applications

In published and preclinical research, Epithalon has been studied across the following areas:

  • Telomerase activation and telomere protection
  • Longevity and cellular aging studies
  • Melatonin regulation and circadian rhythm
  • Skin repair and wound healing

Epithalon in Research: Reconstitution & Study Concentrations

Epithalon is a synthetic tetrapeptide studied for telomerase-activity and pineal-regulation endpoints in longevity research (Khavinson et al.). Research concentrations are model-specific. Reconstitute with bacteriostatic or sterile water for laboratory use only.

Worked example: a 10mg vial reconstituted with 2 mL of bacteriostatic water yields 5.00 mg/mL.

Epithalon — Frequently Asked Questions

What is Epithalon and how does it work?
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on the natural pineal gland peptide epithalamin. It has been observed in preclinical and cell culture studies to activate telomerase, the enzyme responsible for adding protective telomere sequences to chromosome ends. By promoting telomere maintenance, Epithalon is studied for its potential role in cellular longevity and the regulation of age-related gene expression.
What research has been done on Epithalon?
Professor Vladimir Khavinson's research at the Saint Petersburg Institute of Biogerontology (published in Bulletin of Experimental Biology and Medicine) demonstrated that Epithalon activated telomerase in human somatic cells and extended the lifespan of fibroblast cultures beyond the Hayflick limit. Additional studies showed Epithalon influenced melatonin secretion patterns in aging animal models and improved retinal function in age-related retinal degeneration research.
How does Epithalon compare to other telomerase-activating compounds like TA-65?
TA-65 is a plant-derived telomerase activator (cycloastragenol from Astragalus membranaceus) that works through a different mechanism than Epithalon. Epithalon directly influences telomerase gene expression as a peptide bioregulator, while TA-65 activates telomerase indirectly through its small-molecule pathway. Epithalon's peptide structure allows for more targeted research on the relationship between peptide signaling and telomere biology.
What is the recommended reconstitution protocol for Epithalon?
For this 10mg vial, add 1 mL of bacteriostatic water to yield a concentration of 10.0mg/mL. Draw 20 units on a 1mL insulin syringe for a 2 mg dose. Inject BAC water slowly along the inner vial wall — do not shake. Allow the powder to dissolve fully (2–5 minutes). Administer in the PM, every day. Use for 20 days in a row, 3 times per year. Refrigerate reconstituted solution at 2–8°C and use within 30 days.
Is Epithalon legal to buy for research?
Epithalon is sold in the United States as a research chemical for laboratory and in-vitro use only. It is not approved by the FDA for human use and is not sold for human consumption. Researchers are responsible for compliance with all applicable federal, state, and institutional regulations.
How is Epithalon reconstituted for research use?
Epithalon ships as a lyophilized (freeze-dried) powder and is reconstituted with bacteriostatic or sterile water before use in research. The volume of solvent added determines the working concentration — use the Elyte reconstitution calculator to derive the exact concentration for a given vial size and solvent volume.
Does Epithalon come with a Certificate of Analysis?
Yes. Every batch of Epithalon from Elyte Peptides ships with a third-party Certificate of Analysis (COA) documenting identity and HPLC purity (≥98%), so research results can be traced to a verified lot.
