RECONSTITUTION GUIDE
How Much BAC Water for Survodutide?
Quick answer: Add 1 mL of bacteriostatic water to a 5 mg Survodutide vial. This yields a concentration of 5 mg/mL. A standard 2.4 mg research dose then requires 0.48 mL (48 IU on a 100-unit insulin syringe).
Concentration by BAC water volume
Concentration and 2.4 mg draw volume at common BAC water volumes for a 5 mg vial.
| BAC water | Concentration | Dose volume | Draw |
|---|---|---|---|
| 1 mL Standard | 5 mg/mL | 0.48 mL | 48 IU |
| 2 mL | 2.5 mg/mL | 0.96 mL | 96 IU |
| 3 mL | 1.67 mg/mL | 1.44 mL | 144 IU |
| 5 mL | 1 mg/mL | 2.4 mL | 240 IU |
Dose volume at the standard 5 mg/mL concentration
How draw volume changes if you vary the dose at the standard 5 mg + 1 mL reconstitution.
| Dose | Volume | IU draw (100u) |
|---|---|---|
| 1.2 mg | 0.24 mL | 24 IU |
| 2.4 mg Std | 0.48 mL | 48 IU |
| 3.6 mg | 0.72 mL | 72 IU |
| 4.8 mg | 0.96 mL | 96 IU |
| 7.2 mg | 1.44 mL | 144 IU |
Reconstitution steps
- Wipe the top of both the Survodutide vial and the bacteriostatic water vial with alcohol swabs.
- Draw 1 mL of bacteriostatic water into a sterile syringe.
- Inject the water slowly down the inside glass wall of the Survodutide vial. Do not aim directly at the powder.
- Swirl gently until fully dissolved. Never shake.
- Refrigerate at 2–8°C protected from light. Allow to reach room temperature before each draw.
Supplies needed
- Survodutide 5 mg lyophilized vial
- 1 mL bacteriostatic water (0.9% benzyl alcohol)
- 100-unit (1 mL) U-100 insulin syringe
- Alcohol swabs
- Sharps container for disposal
Frequently asked
How much BAC water do I add to a 5 mg Survodutide vial?
For the standard ASCEND research protocol, add 1 mL of bacteriostatic water to a 5 mg Survodutide vial. This yields 5 mg/mL.
What concentration does 1 mL BAC water give for 5 mg Survodutide?
A 5 mg Survodutide vial reconstituted with 1 mL of bacteriostatic water yields 5 mg/mL. A 2.4 mg dose then requires 0.48 mL (48 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for Survodutide?
Bacteriostatic water (0.9% benzyl alcohol) is preferred because it inhibits bacterial growth and allows multi-dose use of the reconstituted vial. Sterile water lacks preservative properties and accelerates peptide degradation once the vial is opened.
How long is Survodutide stable once reconstituted with BAC water?
Most research peptides remain stable for approximately 28 days when reconstituted with bacteriostatic water and stored at 2–8°C protected from light. Refer to peptide-specific stability data for any deviation from this baseline.
What size insulin syringe should I use for Survodutide?
For a 2.4 mg dose (48 IU draw), a 50-unit (0.5 mL) or 100-unit U-100 insulin syringe is appropriate.
