Epithalon Acetate vs SS-31 (Elamipretide)
An educational, source-based comparison of Epithalon Acetate and SS-31 (Elamipretide) — how each peptide works, what it's researched for, and what to know before going deeper.
An N-acetylated variant of Epitalon (Ala-Glu-Asp-Gly) designed to improve metabolic stability and oral bioavailability. Research suggests the same telomerase activation and circadian-modulating properties as the parent peptide.
- Telomerase activity and cellular senescence
- Melatonin rhythm regulation
- Age-related immune restoration
- • Preclinical data; limited human clinical trials.
- • Not FDA-approved.
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.

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Epithalon Acetate | Acetylated Epitalon analogs: bioavailability and efficacy | Biogerontology | 2019 | Acetylation improved plasma half-life while retaining telomerase-inducing activity. |
| SS-31 (Elamipretide) | Elamipretide in primary mitochondrial myopathy (MMPOWER-3) | Neurology | 2020 | Did not meet primary endpoints but showed signals in subgroup analyses. |
