How Much BAC Water for AICAR?
Quick answer: Add 1 mL of bacteriostatic water to a 50 mg AICAR vial. This yields a concentration of 50 mg/mL. A standard 50 mg research dose then requires 1 mL (100 IU on a 100-unit insulin syringe).
Concentration by BAC water volume
Concentration and 50 mg draw volume at common BAC water volumes for a 50 mg vial.
| BAC water | Concentration | Dose volume | Draw |
|---|---|---|---|
| 1 mL Standard | 50 mg/mL | 1 mL | 100 IU |
| 2 mL | 25 mg/mL | 2 mL | 200 IU |
| 3 mL | 16.67 mg/mL | 3 mL | 300 IU |
| 5 mL | 10 mg/mL | 5 mL | 500 IU |
Dose volume at the standard 50 mg/mL concentration
How draw volume changes if you vary the dose at the standard 50 mg + 1 mL reconstitution.
| Dose | Volume | IU draw (100u) |
|---|---|---|
| 25 mg | 0.5 mL | 50 IU |
| 50 mg Std | 1 mL | 100 IU |
| 75 mg | 1.5 mL | 150 IU |
| 100 mg | 2 mL | 200 IU |
| 150 mg | 3 mL | 300 IU |
Reconstitution steps
- Wipe the top of both the AICAR 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 AICAR 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
- AICAR 50 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 50 mg AICAR vial?
For the standard ASCEND research protocol, add 1 mL of bacteriostatic water to a 50 mg AICAR vial. This yields 50 mg/mL.
What concentration does 1 mL BAC water give for 50 mg AICAR?
A 50 mg AICAR vial reconstituted with 1 mL of bacteriostatic water yields 50 mg/mL. A 50 mg dose then requires 1 mL (100 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for AICAR?
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 AICAR 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 AICAR?
A standard 100-unit (1 mL) U-100 insulin syringe is appropriate for a 50 mg AICAR dose.
Can I transport reconstituted AICAR?
Keep it cold in transit. An insulated bag or small cooler with an ice pack holds the 2-8°C range for several hours, which covers most day trips or drives. For longer travel, pack it the same way you would any refrigerated medication, and get it back into a fridge as soon as you arrive. Extended time at room temperature shortens the ~28-day stability window.
