What is it?
A research-only peptide associated with telomerase and ageing hypotheses. It is not an approved longevity medicine.
Synthetic tetrapeptide associated with pineal peptide research programmes.
Mechanism of action
Mechanism not yet fully established.
Proposed mechanism: epitalon has been reported to affect telomerase and geroprotective markers in experimental systems. Mechanism not yet fully established. Independent, modern registrational trials were not identified.
Unproven as a human longevity intervention.
What is it being studied for?
Ageing biology
E · Mechanistic / theoretical evidence onlyMechanistic/theoretical and regional experimental literature exceed the independent Phase 3 evidence base.[1]
Investigational findings are not proven clinical benefits unless an authority has labelled that indication.
Evidence level
Overall human evidence grade: D · Primarily animal / preclinical evidence
Human research
Limited, largely non-ICH literature; not practice-changing.
Preclinical research
Animal, cell and in-vitro findings are listed separately from human effects.
Cell and animal ageing models; interpret cautiously.
