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.

Longevity · Circadian
Epithalon Acetate

Acetylated form of Epitalon with enhanced bioavailability.

Mechanism

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.

Research areas
  • Telomerase activity and cellular senescence
  • Melatonin rhythm regulation
  • Age-related immune restoration
Considerations
  • Preclinical data; limited human clinical trials.
  • Not FDA-approved.

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.
