Key Benefits
Mitochondrial Repair
SS-31 binds to cardiolipin in the inner mitochondrial membrane, stabilizing electron transport and boosting ATP production.
Cardiovascular Protection
Protects heart tissue during ischemia-reperfusion injury. Multiple Phase II clinical trials completed.
Anti-Aging
Improves mitochondrial function which declines with age. Shown to reduce age-related oxidative stress.
Kidney Protection
Demonstrated renoprotective effects in preclinical models of acute kidney injury.
What is SS-31 Peptide Benefits Dosage and Side Effects Guide?
SS-31 (Elamipretide) is a mitochondria-targeting tetrapeptide that binds to cardiolipin, stabilizing the inner mitochondrial membrane and improving electron transport chain efficiency. It has completed multiple Phase II clinical trials.
✅ Pros
- Most clinically-validated peptide
- Phase II trial data in humans
- Multi-organ benefits
- Mitochondria-specific mechanism
- Well-tolerated in clinical studies
❌ Cons
- Expensive compared to other peptides
- Injection required (not orally bioavailable)
- Still in research phase for most uses
- Limited availability from quality sources
Recommended Dosage
| Goal | Dosage | Timing |
|---|---|---|
| General mitochondrial support | 5-10mg weekly | SubQ injection, divided 2-3x/week |
| Cardiovascular support | 10-20mg weekly | SubQ injection, divided doses |
