RECONSTITUTION GUIDE
How Much BAC Water for Glow?
Quick answer: Add 3 mL of bacteriostatic water to a 70 mg Glow vial. This yields a concentration of 23.33 mg/mL. A standard 2.33 mg research dose then requires 0.1 mL (10 IU on a 100-unit insulin syringe).
Concentration by BAC water volume
Concentration and 2.33 mg draw volume at common BAC water volumes for a 70 mg vial.
| BAC water | Concentration | Dose volume | Draw |
|---|---|---|---|
| 1 mL | 70 mg/mL | 0.03 mL | 3.3 IU |
| 2 mL | 35 mg/mL | 0.07 mL | 6.7 IU |
| 3 mL Standard | 23.33 mg/mL | 0.1 mL | 10 IU |
| 5 mL | 14 mg/mL | 0.17 mL | 16.6 IU |
Dose volume at the standard 23.33 mg/mL concentration
How draw volume changes if you vary the dose at the standard 70 mg + 3 mL reconstitution.
| Dose | Volume | IU draw (100u) |
|---|---|---|
| 1.17 mg | 0.05 mL | 5 IU |
| 2.33 mg Std | 0.1 mL | 10 IU |
| 3.5 mg | 0.15 mL | 15 IU |
| 4.66 mg | 0.2 mL | 20 IU |
| 6.99 mg | 0.3 mL | 30 IU |
Reconstitution steps
- Wipe the top of both the Glow vial and the bacteriostatic water vial with alcohol swabs.
- Draw 3 mL of bacteriostatic water into a sterile syringe.
- Inject the water slowly down the inside glass wall of the Glow 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
- Glow 70 mg lyophilized vial
- 3 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 70 mg Glow vial?
For the standard ASCEND research protocol, add 3 mL of bacteriostatic water to a 70 mg Glow vial. This yields 23.33 mg/mL.
What concentration does 3 mL BAC water give for 70 mg Glow?
A 70 mg Glow vial reconstituted with 3 mL of bacteriostatic water yields 23.33 mg/mL. A 2.33 mg dose then requires 0.1 mL (10 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for Glow?
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 Glow 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 Glow?
For a 2.33 mg dose (10 IU draw), a 30-unit (0.3 mL) U-100 insulin syringe gives the finest resolution. A 100-unit syringe also works.
