Quick Answer

SS-31 purity is verified with reverse-phase HPLC, which separates compounds on a C18 column by hydrophobicity and detects the peptide at 214 nm or 280 nm; purity percentage is calculated as the SS-31 peak area relative to the total peak area.

COACH'S BOARD / KEY POINTS

SS-31 (elamipretide) binds cardiolipin in the inner mitochondrial membrane, stabilizing cristae structure and preventing cytochrome c release during oxidative stress.
Clinical trials show SS-31 reduces infarct size by 20–25% in anterior myocardial infarctions when administered within 4 hours of symptom onset.
In heart failure with preserved ejection fraction (HFpEF), 28 days of SS-31 improved 6-minute walk distance by 26 meters and reduced diastolic dysfunction markers by 15%.
Subcutaneous dosing at 1–4mg daily is the standard protocol for chronic mitochondrial conditions. Half-life is 2–4 hours in plasma but mitochondrial retention persists beyond 24 hours.
Unlike traditional antioxidants (CoQ10, MitoQ), SS-31 prevents the structural membrane changes that drive ROS production rather than scavenging free radicals after they form.
Barth syndrome trials showed SS-31 increased skeletal muscle ATP production by 31% and reduced mitochondrial distress biomarkers by 40% over 12 weeks.
Research-grade SS-31 requires HPLC verification of the dimethyltyrosine residue. Improper synthesis produces inactive peptides despite correct molecular weight.
