SS-31 (Elamipretide) enhances mitochondrial function by optimizing cardiolipin in the inner membrane, improving ATP production 10-40% and reducing oxidative stress.

What Is SS-31?

SS-31 is a tetrapeptide designed to optimize mitochondrial function by binding cardiolipin in the inner mitochondrial membrane, improving electron transport chain efficiency and ATP synthesis while reducing ROS generation.

Mitochondrial ATP Production

Healthy mitochondria produce ATP efficiently; aging mitochondria leak electrons. SS-31 improves electron transport chain function through cardiolipin optimization, with research demonstrating 10-40% improvements in mitochondrial respiration.

ROS Reduction

SS-31 reduces pathological ROS generation by optimizing electron flow. Result: 20-50% reduction in oxidative damage markers in aging models.

Energy and Fatigue

SS-31 restores ATP production capacity. Users report sustained energy, reduced afternoon crashes, faster recovery within 2-3 weeks.

Cardiovascular Function

The heart depends on ATP. SS-31 improves cardiac mitochondrial function, enhancing contractility and metabolic efficiency in clinical trials.

Neuroprotection

SS-31 crosses the blood-brain barrier and preserves neuronal function in stress states including stroke and neurodegeneration.

Metabolic Health

SS-31 reverses age-related metabolic dysfunction: improves glucose tolerance, reduces visceral fat, preserves muscle mass.

Exercise Performance

Mitochondria limit aerobic capacity. SS-31 enhances VO2 max (5-15%), endurance, and recovery when combined with training.

Safety Profile

SS-31 shows excellent safety in clinical trials. No immunogenicity, organ toxicity, or significant adverse events reported.

Research Status

SS-31 has genuine Phase II clinical trial data. Trials in heart failure and mitochondrial disease show benefit, but trials are small and disease-focused.
