Catalogue number



Epithalon Synthetic is a single, non-glycosylated polypeptide chain containing 4 amino acids, having a molecular mass of 390.35  Dalton and a Molecular formula of C14H22N4O9. 

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.


The protein was lyophilized with no additives.        


It is recommended to reconstitute the lyophilized Epithalon in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.


Lyophilized Epithalon although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Epithalon should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Please prevent freeze-thaw cycles.


Greater than 97.0% as determined by analysis by RP-HPLC.

Amino acid sequence

H-Ala-Glu-Asp-Gly-OH .

Safety Data Sheet


Epitalon, also known as Epithalon, is a synthetic tetrapeptide that has been a focal point in the field of aging and longevity research. This peptide, consisting of four amino acids, is derived from the pineal gland and has been associated with a variety of biological effects, most notably its potential role in extending the lifespan of cells.

Epitalon's primary function is its interaction with telomeres, the protective caps at the ends of chromosomes that shorten as cells divide. By stimulating the production of telomerase, an enzyme that can repair and lengthen telomeres, Epitalon may slow down the aging process at a cellular level.

Numerous studies have explored the potential of Epitalon in extending the lifespan of organisms. For instance, Khavinson and colleagues (2003) found that Epitalon increased the lifespan of fruit flies, while Anisimov et al. (2003) reported similar results in mice. These findings suggest that Epitalon could potentially have similar effects in humans.

Epitalon has also been studied for its role in regulating circadian rhythms. Korkushko et al. (2011) found that Epitalon could restore disrupted circadian rhythms in elderly people, suggesting potential applications in sleep disorders and other conditions related to circadian rhythm disruption.

Beyond its potential role in aging and longevity, Epitalon has been explored for its potential therapeutic applications. Anisimov et al. (2011) found that Epitalon could reduce the incidence of spontaneous tumors in mice, suggesting potential applications in cancer prevention.

While research on Epitalon is promising, it is important to note that most studies have been conducted in animals or in vitro. More research is needed to fully understand the potential effects and applications of Epitalon in humans. However, the existing body of research suggests that Epitalon could be a promising tool in the fight against aging and age-related diseases.
