How the SS-31 (Elamipretide) math works
A 10 mg vial holds 10,000 mcg of SS-31 (Elamipretide). Adding 2 mL of bacteriostatic water spreads that over 2 mL, so the solution is 10,000 ÷ 2 = 5,000 mcg per mL. A U-100 insulin syringe has 100 units per mL, so each unit is 0.01 mL and holds 5,000 × 0.01 = 50 mcg.
To turn an amount into units, divide it by the amount per unit. The calculator above does this for you, and warns you when a draw is too small to measure or bigger than the syringe.
SS-31 (Elamipretide) concentration by vial size and water volume
Each cell shows the concentration and how much one U-100 unit holds. The app's reference lists 2 mL for a 10 mg vial.

Before you reconstitute
Check the vial label for the actual amount of peptide, because the calculation depends on it. Use an insulin syringe marked U-100 so that 100 units equal 1 mL, and write down how much water you added so the concentration is known later.

Frequently asked questions
How much BAC water goes in a 10 mg SS-31 (Elamipretide) vial?
The reconstitution reference in the PeptidesAI app lists 2 mL for a 10 mg vial, which makes 5,000 mcg/mL. The water volume is a choice, not a fixed rule: more water makes a weaker solution and larger draws, and the total amount of peptide in the vial stays the same.
How much is one unit of SS-31 (Elamipretide) on an insulin syringe?
It depends on the concentration. A 10 mg vial with 2 mL of water is 5,000 mcg/mL, so one unit on a U-100 syringe (0.01 mL) holds 50 mcg. The table on this page shows other vial and water combinations.
What vial sizes does SS-31 (Elamipretide) come in?
The PeptidesAI app lists 10 mg, 50 mg vials for SS-31 (Elamipretide). Use the calculator's vial field for any other size.
Does this calculator tell me how much to use?
No. It converts an amount you already have into syringe units and millilitres. It does not suggest an amount, and nothing on this page is medical advice.
