SS-31 Calculator
SS-31 (also known as Elamipretide) reconstitution and dosage reference — calculate vial concentration, BAC water volume, and exact syringe units below.
Also known as: Elamipretide, MTP-131
At the reference preset of a 40mg SS-31 vial reconstituted with 2 mL of bacteriostatic water, a 20mg dose measures 100 units on a U-100 insulin syringe.
SS-31 (elamipretide) is a synthetic mitochondria-targeted tetrapeptide that binds cardiolipin to stabilize cristae and maintain electron-transport-chain function.

How to use this calculator›
- 1. Vial — the peptide amount printed on the vial, in milligrams.
- 2. BAC water — the bacteriostatic water added to the vial. More water means a lower concentration and a larger, easier-to-read draw.
- 3. Dose — the single dose being measured, in milligrams.
- 4. Syringe — the barrel being drawn into. The diagram rescales to that syringe, so the same dose sits at a different mark on a 0.3 mL barrel than on a U-100.

What is SS-31?
SS-31 (elamipretide) is a synthetic mitochondria-targeted tetrapeptide that binds cardiolipin to stabilize cristae and maintain electron-transport-chain function. It has been investigated in clinical trials for primary mitochondrial myopathy and Barth syndrome.
