Longevity comparison

Epitalon vs SS-31 (Elamipretide)

An educational, source-based comparison of Epitalon and SS-31 (Elamipretide) — how each peptide works, what it's researched for, and what to know before going deeper.

Longevity · Circadian
Epitalon

Pineal peptide researched for telomere and circadian support.

Mechanism

A synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on epithalamin, a pineal gland extract. Research from Russian gerontology groups has examined effects on telomerase activity, melatonin rhythm, and lifespan in rodent and limited human cohorts.

Research areas
  • Telomerase activity (in vitro)
  • Circadian and melatonin rhythm
  • Age-related morbidity in long-term Russian cohort studies
Considerations
  • Most research is Russian and methodologically heterogeneous.
  • Not FDA-approved.
  • Independent replication is limited.

Mitochondrial
SS-31 (Elamipretide)

Cardiolipin-targeting peptide studied for mitochondrial dysfunction.

Mechanism

A tetrapeptide that selectively binds cardiolipin on the inner mitochondrial membrane, stabilizing cristae structure, preserving electron transport efficiency, and reducing reactive oxygen species production.

Research areas
  • Heart failure with preserved ejection fraction
  • Primary mitochondrial myopathy
  • Age-related muscle dysfunction
  • Dry AMD (ophthalmology)
Considerations
  • Investigational; not FDA-approved.
  • Injection-site reactions are common in trials.
