How Much BAC Water for N-Acetyl Selank Amidate?
Quick answer: Add 5 mL of bacteriostatic water to a 5 mg N-Acetyl Selank Amidate vial. This yields a concentration of 1000 µg/mL. A standard 250 µg research dose then requires 0.25 mL (25 IU on a 100-unit insulin syringe).
Concentration by BAC water volume
Concentration and 250 µg draw volume at common BAC water volumes for a 5 mg vial.
| BAC water | Concentration | Dose volume | Draw |
|---|---|---|---|
| 1 mL | 5000 µg/mL | 0.05 mL | 5 IU |
| 2 mL | 2500 µg/mL | 0.1 mL | 10 IU |
| 3 mL | 1666.67 µg/mL | 0.15 mL | 15 IU |
| 5 mL Standard | 1000 µg/mL | 0.25 mL | 25 IU |
Dose volume at the standard 1000 µg/mL concentration
How draw volume changes if you vary the dose at the standard 5 mg + 5 mL reconstitution.
| Dose | Volume | IU draw (100u) |
|---|---|---|
| 125 µg | 0.13 mL | 12.5 IU |
| 250 µg Std | 0.25 mL | 25 IU |
| 375 µg | 0.38 mL | 37.5 IU |
| 500 µg | 0.5 mL | 50 IU |
| 750 µg | 0.75 mL | 75 IU |
Reconstitution steps
- Wipe the top of both the N-Acetyl Selank Amidate vial and the bacteriostatic water vial with alcohol swabs.
- Draw 5 mL of bacteriostatic water into a sterile syringe.
- Inject the water slowly down the inside glass wall of the N-Acetyl Selank Amidate 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
- N-Acetyl Selank Amidate 5 mg lyophilized vial
- 5 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 N-Acetyl Selank Amidate vial?
For the standard ASCEND research protocol, add 5 mL of bacteriostatic water to a 5 mg N-Acetyl Selank Amidate vial. This yields 1000 µg/mL.
What concentration does 5 mL BAC water give for 5 mg N-Acetyl Selank Amidate?
A 5 mg N-Acetyl Selank Amidate vial reconstituted with 5 mL of bacteriostatic water yields 1000 µg/mL. A 250 µg dose then requires 0.25 mL (25 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for N-Acetyl Selank Amidate?
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 Selank Amidate 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 Selank Amidate?
For a 250 µg dose (25 IU draw), a 30-unit (0.3 mL) U-100 insulin syringe gives the finest resolution. A 100-unit syringe also works.
