Dosage protocol · Longevity & Mitochondrial Health
SS-31 10 mg
Typical daily range: 5–10 mg once daily (gradual titration); advanced protocols may reach 15–20 mg/day under supervision.
- Reconstitute: Add 1.0 mL bacteriostatic water → 10 mg/mL concentration for single‑syringe convenience.
- Typical daily range: 5–10 mg once daily (gradual titration); advanced protocols may reach 15–20 mg/day under supervision.
- Easy measuring: At 10 mg/mL, 1 unit = 0.01 mL = 100 mcg on a U‑100 insulin syringe.
- Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); use within 4 weeks.

How it works
SS-31 is a small, synthetic mitochondria-targeted tetrapeptide (four amino acids) that is better known by its clinical development name, elamipretide, along with earlier designations MTP-131 and Bendavia.[1] It belongs to the Szeto-Schiller family of aromatic-cationic peptides, originally designed to concentrate specifically within mitochondria rather than act at a cell-surface receptor.
Unlike many of the compounds covered on this site, elamipretide is a genuine investigational drug that has progressed into human clinical trials, including Phase 2 and Phase 3 studies, for specific rare mitochondrial diseases. That places it well ahead of unapproved research chemicals in terms of regulatory scrutiny, even though it is not yet a broadly FDA-approved medicine.
Benefits & side effects
Preclinical evidence is broad: mouse and cellular studies report improved mitochondrial respiration, reduced oxidative damage, and better skeletal-muscle bioenergetics in aged or injured tissue models.[4] Human evidence exists but is indication-specific and mixed. Clinical trials have evaluated elamipretide in primary mitochondrial myopathy (measuring walking distance and fatigue), Barth syndrome, heart failure, and ischemia-reperfusion settings, with results that vary by trial and endpoint rather than uniformly confirming benefit.[5]
The key distinction researchers draw is between biomarker improvement — such as better mitochondrial respiration readings — and clinical outcomes that matter to patients, like function, symptoms, or survival. For SS-31, the biomarker story is more consistent than the clinical-outcome story, and both should be read as disease-specific rather than generalizable to healthy adults seeking energy or anti-aging effects.
