Epitalon, also written Epithalon, is a small synthetic tetrapeptide (the amino acids alanine, glutamic acid, aspartic acid and glycine, abbreviated AEDG). It is derived from epithalamin, a substance from the pineal gland, and is best known in longevity research: it is studied around the enzyme telomerase, the length of telomeres and the regulation of the sleep-wake rhythm. At GradePurity you buy it as a research-grade vial: ≥99% HPLC purity and same-day shipping from the Netherlands.
What does Epitalon do?
Epitalon is best known in research as a "longevity peptide". The attention centres on telomeres: the protective ends of your chromosomes that get shorter with every cell division. It is thought that Epitalon switches on the enzyme telomerase, which can help maintain those telomeres, and that is exactly where researchers look for the link to ageing. It is also associated with the pineal gland and the sleep-wake rhythm. At GradePurity you buy it as a research-grade material, not for use in humans.
How does Epitalon work?
Epitalon comes out of research on the pineal gland. Researchers took apart epithalamin, a natural extract from that gland, and distilled this short tetrapeptide (AEDG) from it as the presumed active part. In cell and animal studies it is thought that Epitalon stimulates the production of telomerase (via the hTERT gene), so that cells would maintain their telomeres for longer. Most of what we know comes from that research, partly from Russian groups.
Epitalon and telomeres
Telomeres are a central theme in ageing research: the shorter they get, the fewer times a cell can still divide. Telomerase is the enzyme that can lengthen telomeres again, but in most adult cells it is switched off. The reason Epitalon gets so much attention is that, in research, it is associated with switching telomerase on.
Epitalon and the sleep-wake rhythm
Besides the telomere angle, Epitalon is also studied around the pineal gland, the gland that makes melatonin and so regulates your day-night rhythm. It is thought that Epitalon can support that melatonin production, which is why it often comes up in research in the context of sleep and circadian rhythm. As with the telomeres, this comes mainly from early research; GradePurity supplies it for laboratory use only.
Dosage and form
On the market you see Epitalon as a freeze-dried vial and sometimes as a ready-made spray. We deliberately supply the research-grade vial (10 mg), which you mix yourself with bacteriostatic water, so you set the concentration in the lab and work with the pure peptide. In the literature it is usually studied in short courses of about ten to twenty days, sometimes repeated a few times a year. We deliberately give no human dosing advice: Epitalon is a research material, and the right amount depends on the study design.
Side effects and safety
In research, Epitalon is known for a mild profile; the reported reactions are usually light, such as a temporary reaction at the injection site. At the same time, honesty matters: large long-term human data are lacking, and it is approved by neither the EMA nor the FDA. Because telomerase is also involved in cell division, the literature sometimes mentions caution.
Purity and lab testing
With a short peptide like Epitalon, usable research stands or falls with purity. That is why we test every batch by HPLC for ≥99% purity and identity, and ship it freeze-dried so it arrives stable. So you know exactly what you are holding, the exact specifications (purity, sequence, molecular weight, CAS) are in the table at the bottom of this page.
