SS-31 dosage calculator
SS-31 vials are commonly labelled 5 mg, 10 mg. This calculator divides the vial mass by the diluent volume you enter to show concentration, then converts your own target amount into millilitres and syringe units. It states no dose, chooses no amount and stores nothing.
This page is a calculation tool. The amounts you enter are values you decided; this page states no dose and gives no medical advice.
SS-31 vial concentration grid
This table answers one arithmetic question: what concentration results when a labelled vial mass is divided by a measured diluent volume? It does not select either value.
| Vial mass | Diluent | Concentration | Same concentration |
|---|---|---|---|
| 5 mg | 0.5 mL | 10,000 mcg/mL | 10 mg/mL |
| 5 mg | 1 mL | 5,000 mcg/mL | 5 mg/mL |
| 5 mg | 1.5 mL | 3,333.33 mcg/mL | 3.333 mg/mL |
| 5 mg | 2 mL | 2,500 mcg/mL | 2.5 mg/mL |
| 5 mg | 2.5 mL | 2,000 mcg/mL | 2 mg/mL |
| 5 mg | 3 mL | 1,666.67 mcg/mL | 1.667 mg/mL |
| 5 mg | 5 mL | 1,000 mcg/mL | 1 mg/mL |
| 10 mg | 0.5 mL | 20,000 mcg/mL | 20 mg/mL |
| 10 mg | 1 mL | 10,000 mcg/mL | 10 mg/mL |
| 10 mg | 1.5 mL | 6,666.67 mcg/mL | 6.667 mg/mL |
| 10 mg | 2 mL | 5,000 mcg/mL | 5 mg/mL |
| 10 mg | 2.5 mL | 4,000 mcg/mL | 4 mg/mL |
| 10 mg | 3 mL | 3,333.33 mcg/mL | 3.333 mg/mL |
| 10 mg | 5 mL | 2,000 mcg/mL | 2 mg/mL |
SS-31 physical-property record
SS-31 and elamipretide are linked names
PubChem records elamipretide with formula C32H49N9O5 and molecular weight 639.8 g/mol. SS-31 and MTP-131 are aliases used for the same core compound in technical literature, while supplier products may use a trifluoroacetate salt. A complete record should retain the alias, formal name and chemical form so the free-peptide molecular weight is not confused with the salt product's formula mass. Sources: PubChem: elamipretide compound record · Cayman Chemical: elamipretide TFA specification.
Elamipretide TFA handling specification
Cayman reports water solubility at 25 mg/mL and storage at -20 C for its elamipretide TFA material. That value belongs to the cataloged salt and is not a universal reconstitution concentration. The calculator does not use it as a preset or stability claim. It accepts the actual measured volume attached to the vial record. Sources: Cayman Chemical: elamipretide TFA specification.
Alias tracking is important for SS-31
A record may arrive under SS-31, elamipretide or MTP-131. Keeping all printed aliases, source catalog, lot, salt form and purity statement together prevents duplicate inventory entries and makes source checking possible. PubChem supports the formal compound identity, while Cayman's page supports one TFA reference product. Neither source proves that an unrelated vial has the same composition.

Physical facts remain outside clinical interpretation
The molecular formula, molecular weight and water-solubility result can describe a material without saying how it should be used. This page keeps that distinction explicit. The live calculator performs mass and volume arithmetic from user inputs, states no dose and provides no treatment schedule. It does not convert an investigational name or supplier specification into a medical recommendation. Sources: PubChem: elamipretide compound record · Cayman Chemical: elamipretide TFA specification.
How to use the calculator
- Read the total mass from your own vial label and enter it in milligrams.
- Enter the diluent volume you actually measured, not an intended or remembered value.
- Enter your own target amount and select the calibration printed on your syringe barrel.
- Record the concentration with the result so the syringe-unit figure remains interpretable later.
Source and identity record
Use the compound reference page and these external database searches when checking identity: PubMed literature search for SS-31 · PubChem compound database · PubChem: elamipretide compound record · Cayman Chemical: elamipretide TFA specification. A database record does not authenticate a vial.
Frequently asked questions
How much bacteriostatic water for a 5 mg SS-31 vial?
This calculator does not choose a diluent volume. Enter the volume you decided to add to the 5 mg vial and it will show the resulting concentration. The page supplies arithmetic, not an instruction.
How much bacteriostatic water for a 10 mg SS-31 vial?
There is no universal volume selected by this page. Use the value you measured or were instructed to use; the calculator then divides the 10 mg label mass by that volume.
Does the SS-31 calculator recommend a dose?
No. The target amount is always entered by the user. The tool provides no starting amount, maximum amount, progression, frequency or schedule.
Why does the syringe calibration matter?
A syringe unit is a volume marking. U-100, U-50 and U-40 barrels use different numbers of units per millilitre, so the same solution volume produces different markings.
