SS-31 (Elamipretide): 50 mg vial with 3 mL water
Quick answer
Adding 3 mL of bacteriostatic water to a 50 mg SS-31 (Elamipretide) vial gives 16.67 mg/mL (16666.7 mcg/mL), so each unit on a U-100 insulin syringe holds 166.7 mcg. A 200 mcg dose is 1.2 units (0.012 mL), and the vial holds about 250 doses of that size.
Concentration
- Vial: 50 mg SS-31 (Elamipretide)
- Bacteriostatic water: 3 mL (the volume in the Crestigen protocol)
- Concentration: 16.67 mg/mL (16666.7 mcg/mL)
- 1 unit on a U-100 syringe = 166.7 mcg
SS-31 (Elamipretide) dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 5 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 10000 |
| 10 mcg (protocol dose) | 0.1 units, too small to measure reliably | 0.001 mL | 5000 |
| 200 mcg | 1.2 units | 0.012 mL | 250 |
| 250 mcg | 1.5 units | 0.015 mL | 200 |
| 300 mcg | 1.8 units | 0.018 mL | 166 |
| 500 mcg | 3 units | 0.03 mL | 100 |
| 750 mcg | 4.5 units | 0.045 mL | 66 |
| 1 mg | 6 units | 0.06 mL | 50 |

Common questions
How many units is 200 mcg of SS-31 (Elamipretide) from a 50 mg vial with 3 mL water?
200 mcg is 1.2 units (0.012 mL) on a U-100 insulin syringe. With 3 mL of water in a 50 mg vial, each unit holds 166.7 mcg. For comparison: 250 mcg = 1.5 units, 300 mcg = 1.8 units, 500 mcg = 3 units.
What is the concentration of a 50 mg SS-31 (Elamipretide) vial mixed with 3 mL of water?
50 mg divided by 3 mL is 16.67 mg/mL, or 16666.7 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 166.7 mcg per unit.
How many 200 mcg doses are in a 50 mg vial?
About 250. The water volume changes how many units each dose takes, not how many doses the vial holds.
How much water should I add to a 50 mg SS-31 (Elamipretide) vial?
3 mL is the volume used in the Crestigen SS-31 (Elamipretide) protocol. More water makes each dose a larger, easier-to-measure number of units; less water keeps injections smaller.
