How Much BAC Water for SLU-PP-332?

Quick answer: Add 3 mL of bacteriostatic water to a 5 mg SLU-PP-332 vial. This yields a concentration of 1.67 mg/mL. A standard 1.25 mg research dose then requires 0.75 mL (75 IU on a 100-unit insulin syringe).

Reconstitution steps

  1. Wipe the top of both the SLU-PP-332 vial and the bacteriostatic water vial with alcohol swabs.
  2. Draw 3 mL of bacteriostatic water into a sterile syringe.
  3. Inject the water slowly down the inside glass wall of the SLU-PP-332 vial. Do not aim directly at the powder.
  4. Swirl gently until fully dissolved. Never shake.
  5. Refrigerate at 2–8°C protected from light. Allow to reach room temperature before each draw.

Frequently asked

How much BAC water do I add to a 5 mg SLU-PP-332 vial?
For the standard ASCEND research protocol, add 3 mL of bacteriostatic water to a 5 mg SLU-PP-332 vial. This yields 1.67 mg/mL.
What concentration does 3 mL BAC water give for 5 mg SLU-PP-332?
A 5 mg SLU-PP-332 vial reconstituted with 3 mL of bacteriostatic water yields 1.67 mg/mL. A 1.25 mg dose then requires 0.75 mL (75 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for SLU-PP-332?
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 SLU-PP-332 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 SLU-PP-332?
A standard 100-unit (1 mL) U-100 insulin syringe is appropriate for a 1.25 mg SLU-PP-332 dose.
