Epitalon is a synthetic tetrapeptide based on Khavinson's Russian gerontology research at the St. Petersburg Institute of Bioregulation. The signature feature of Epitalon protocols is short pulsed courses (10–20 days) repeated periodically rather than continuous use. Western validation of the original telomerase and longevity claims is limited.

Epitalon Dosing by Use Case

Commonly cited protocols vary by what Epitalon is being used for. The table below summarizes typical ranges reported in clinical practice and published literature.

Use with caution

Epitalon has minimal reported acute toxicity but its long-term effects in Western populations are not validated.

  • Reported side effects in practice are minimal — injection-site reactions are the most common.
  • Original telomerase and longevity claims come from Russian research that has not been independently replicated at scale in Western institutions.
  • Long-term safety beyond several pulsed cycles is not well-characterized.
  • Not FDA-approved.
Do not use if
  • Active or recent malignancy (theoretical concern with telomerase activation claims)
  • Pregnancy or breastfeeding

Epitalon Dosing FAQ

Khavinson's protocol design is based on a 'biological reset' rationale — short pulsed courses are theorized to reset pineal and aging signaling rather than continuously stimulate it. Whether this is mechanistically correct or simply a heuristic is debated.

Russian rodent studies report lifespan extension; Western replication at scale has not been published. Human longevity data does not exist. Treat anti-aging claims as hypothesized, not validated.
