Humanin vs SS-31 (Elamipretide)
An educational, source-based comparison of Humanin and SS-31 (Elamipretide) — how each peptide works, what it's researched for, and what to know before going deeper.
Mitochondrial-derived peptide studied for neuroprotection and metabolism.
A 24-amino-acid peptide encoded in mitochondrial DNA. Research suggests cytoprotective effects against Alzheimer's-related toxicity, improved insulin sensitivity, and modulation of apoptotic signaling.
- Neuroprotection (Alzheimer's models)
- Insulin sensitivity
- Cardiovascular protection in animal models
- • Early-stage research.
- • No approved therapeutic use.
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 |
|---|---|---|---|---|
| Humanin | Humanin: a harbinger of mitochondrial-derived peptides | Trends in Endocrinology & Metabolism | 2013 | Reviewed cytoprotective, metabolic, and longevity-relevant signaling. |
| SS-31 (Elamipretide) | Elamipretide in primary mitochondrial myopathy (MMPOWER-3) | Neurology | 2020 | Did not meet primary endpoints but showed signals in subgroup analyses. |
