MOTS-c vs SS-31 (Elamipretide)

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

Mitochondrial · Metabolic
MOTS-c

Mitochondrial-derived peptide studied for metabolic health.

Mechanism

A 16-amino-acid peptide encoded within the mitochondrial 12S rRNA gene. Research suggests it activates AMPK, enhances insulin sensitivity, and regulates nuclear gene expression in response to metabolic stress — positioning it as a candidate mitochondrial-nuclear signaling peptide.

Research areas
  • Insulin sensitivity
  • Exercise capacity and mitochondrial biogenesis
  • Age-related metabolic decline
  • Obesity models
Considerations
  • Early-stage research; no approved human therapeutic use.
  • Long-term effects unknown.

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.
