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.
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.
- Telomerase activity (in vitro)
- Circadian and melatonin rhythm
- Age-related morbidity in long-term Russian cohort studies
- • Most research is Russian and methodologically heterogeneous.
- • Not FDA-approved.
- • Independent replication is limited.
Cardiolipin-targeting peptide studied for mitochondrial dysfunction.
A tetrapeptide that selectively binds cardiolipin on the inner mitochondrial membrane, stabilizing cristae structure, preserving electron transport efficiency, and reducing reactive oxygen species production.
- Heart failure with preserved ejection fraction
- Primary mitochondrial myopathy
- Age-related muscle dysfunction
- Dry AMD (ophthalmology)
- • Investigational; not FDA-approved.
- • Injection-site reactions are common in trials.
Trial-evidence rating
Educational grade reflecting how many peer-reviewed studies and FDA actions we cite for each peptide. Not a clinical recommendation.
Two cited studies; independent replication needed.
Early-stage research; conclusions are tentative.
Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Epitalon | Effect of Epitalon on telomere length in human somatic cells | Bulletin of Experimental Biology and Medicine | 2003 | Reported telomerase induction and telomere elongation in cultured cells. |
| Epitalon | Long-term Epitalon administration in elderly subjects | Neuroendocrinology Letters | 2003 | Observed reduction in age-related mortality markers over multi-year follow-up. |
| SS-31 (Elamipretide) | Elamipretide in primary mitochondrial myopathy (MMPOWER-3) | Neurology | 2020 | Did not meet primary endpoints but showed signals in subgroup analyses. |
