A short peptide associated with the Russian "bioregulator" program; longevity and telomerase claims rest mainly on small, often non-replicated, largely Russian-language studies of variable quality.
Epitalon is a short four-amino-acid peptide from the Russian 'bioregulator' research tradition, promoted for anti-aging and longevity effects.
Its proposed mechanism is that it binds DNA to influence gene expression and activates telomerase, the enzyme that maintains the protective caps on chromosomes — the supposed link to slowing cellular aging. It's also claimed to influence the pineal gland and melatonin.
These ideas are hypothesis-level. The supporting studies are small, largely non-English, and not independently replicated to a high standard, so the mechanism should be treated as unproven rather than established.
