How Much BAC Water for Kisspeptin-54?

Quick answer: Add 1 mL of bacteriostatic water to a 1 mg Kisspeptin-54 vial. This yields a concentration of 1000 µg/mL. A standard 438 µg research dose then requires 0.44 mL (43.8 IU on a 100-unit insulin syringe).

Reconstitution steps

  1. Wipe the top of both the Kisspeptin-54 vial and the bacteriostatic water vial with alcohol swabs.
  2. Draw 1 mL of bacteriostatic water into a sterile syringe.
  3. Inject the water slowly down the inside glass wall of the Kisspeptin-54 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 1 mg Kisspeptin-54 vial?
For the standard ASCEND research protocol, add 1 mL of bacteriostatic water to a 1 mg Kisspeptin-54 vial. This yields 1000 µg/mL.
What concentration does 1 mL BAC water give for 1 mg Kisspeptin-54?
A 1 mg Kisspeptin-54 vial reconstituted with 1 mL of bacteriostatic water yields 1000 µg/mL. A 438 µg dose then requires 0.44 mL (43.8 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for Kisspeptin-54?
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 Kisspeptin-54 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 Kisspeptin-54?
For a 438 µg dose (43.8 IU draw), a 50-unit (0.5 mL) or 100-unit U-100 insulin syringe is appropriate.
