How Much BAC Water for N-Acetyl Semax?

Quick answer: Add 2 mL of bacteriostatic water to a 5 mg N-Acetyl Semax vial. This yields a concentration of 2500 µg/mL. A standard 300 µg research dose then requires 0.12 mL (12 IU on a 100-unit insulin syringe).

Reconstitution steps

  1. Wipe the top of both the N-Acetyl Semax vial and the bacteriostatic water vial with alcohol swabs.
  2. Draw 2 mL of bacteriostatic water into a sterile syringe.
  3. Inject the water slowly down the inside glass wall of the N-Acetyl Semax 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 N-Acetyl Semax vial?
For the standard ASCEND research protocol, add 2 mL of bacteriostatic water to a 5 mg N-Acetyl Semax vial. This yields 2500 µg/mL.
What concentration does 2 mL BAC water give for 5 mg N-Acetyl Semax?
A 5 mg N-Acetyl Semax vial reconstituted with 2 mL of bacteriostatic water yields 2500 µg/mL. A 300 µg dose then requires 0.12 mL (12 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for N-Acetyl Semax?
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 N-Acetyl Semax 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 N-Acetyl Semax?
For a 300 µg dose (12 IU draw), a 30-unit (0.3 mL) U-100 insulin syringe gives the finest resolution. A 100-unit syringe also works.
