How Much BAC Water for L-Carnitine?
Quick answer: Add 5 mL of bacteriostatic water to a 1000 mg L-Carnitine vial. This yields a concentration of 200 mg/mL. A standard 1000 mg research dose then requires 5 mL (500 IU on a 100-unit insulin syringe).
Concentration by BAC water volume
Concentration and 1000 mg draw volume at common BAC water volumes for a 1000 mg vial.
| BAC water | Concentration | Dose volume | Draw |
|---|---|---|---|
| 1 mL | 1000 mg/mL | 1 mL | 100 IU |
| 2 mL | 500 mg/mL | 2 mL | 200 IU |
| 3 mL | 333.33 mg/mL | 3 mL | 300 IU |
| 5 mL Standard | 200 mg/mL | 5 mL | 500 IU |
Dose volume at the standard 200 mg/mL concentration
How draw volume changes if you vary the dose at the standard 1000 mg + 5 mL reconstitution.
| Dose | Volume | IU draw (100u) |
|---|---|---|
| 500 mg | 2.5 mL | 250 IU |
| 1000 mg Std | 5 mL | 500 IU |
| 1500 mg | 7.5 mL | 750 IU |
| 2000 mg | 10 mL | 1000 IU |
| 3000 mg | 15 mL | 1500 IU |
Reconstitution steps
- Wipe the top of both the L-Carnitine 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 L-Carnitine 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
- L-Carnitine 1000 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 1000 mg L-Carnitine vial?
For the standard ASCEND research protocol, add 5 mL of bacteriostatic water to a 1000 mg L-Carnitine vial. This yields 200 mg/mL.
What concentration does 5 mL BAC water give for 1000 mg L-Carnitine?
A 1000 mg L-Carnitine vial reconstituted with 5 mL of bacteriostatic water yields 200 mg/mL. A 1000 mg dose then requires 5 mL (500 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for L-Carnitine?
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 L-Carnitine 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 L-Carnitine?
A standard 100-unit (1 mL) U-100 insulin syringe is appropriate for a 1000 mg L-Carnitine dose.
