SS-31 (Elamipretide) amounts reported in the literature
SS-31 (Elamipretide) is a mitochondria-targeting tetrapeptide (cardiolipin binder) studied in cardiolipin and mitochondrial-bioenergetics research. The table below summarizes the arms described in published protocols. It is a literature reference, not a protocol to follow.
| Study arm | Reported amount | Cadence |
|---|---|---|
| Standard arm | 5 mg | daily |
| Extended arm | 10 mg | every other day |
Concentration math
Standard preparation: 50 mg + 5 mL = 10 mg/mL. On a U-100 insulin syringe, 100 units = 1 mL, so:
| Concentration | 0.5 mg | 1 mg | 2 mg | 5 mg |
|---|---|---|---|---|
| 2.5 mg/mL | 20 units | 40 units | 80 units | — |
| 5 mg/mL | 10 units | 20 units | 40 units | 100 units |
| 10 mg/mL | 5 units | 10 units | 20 units | 50 units |
Change the diluent volume and every number changes proportionally. The peptide calculator does the conversion for any vial size and target amount.
Why escalation intervals in the literature are long
Across published protocols in this class, step-ups are spaced in multi-week blocks rather than compressed. Study designs prioritize tolerability data at each level before advancing, which is why the reported schedules look conservative compared to what circulates informally.
