Epitalon
Epitalon (also spelled Epithalon) is a tetrapeptide synthesised in 1980 by Vladimir Khavinson at the St Petersburg Institute of Bioregulation and Gerontology. It is one of a class of "peptide bioregulators" with research focused on pineal-gland function, melatonin regulation, and telomerase activity. The literature is dominated by the Khavinson group and Russian-language journals; independent Western replication is limited.
What the literature claims
- · Telomerase activation in human cell cultures (Khavinson 2003).
- · Lifespan extension in rodent and avian models (Khavinson group, multiple papers).
- · Effects on melatonin and circadian regulation in animal models.
- · Cancer-incidence reduction claims in long-running rodent studies.
The literature is methodologically thin compared to mainstream peptide research. Independent replication is the persistent gap. Treat the published claims as preliminary findings from a single research school rather than established science.
UK regulatory status
