How Much BAC Water for Snap-8 (Argireline)?
Quick answer: Add 2 mL of bacteriostatic water to a 5 mg Snap-8 (Argireline) vial. This yields a concentration of 2.5 mg/mL. A standard 1 mg research dose then requires 0.4 mL (40 IU on a 100-unit insulin syringe).
Concentration by BAC water volume
Concentration and 1 mg draw volume at common BAC water volumes for a 5 mg vial.
| BAC water | Concentration | Dose volume | Draw |
|---|---|---|---|
| 1 mL | 5 mg/mL | 0.2 mL | 20 IU |
| 2 mL Standard | 2.5 mg/mL | 0.4 mL | 40 IU |
| 3 mL | 1.67 mg/mL | 0.6 mL | 60 IU |
| 5 mL | 1 mg/mL | 1 mL | 100 IU |
Dose volume at the standard 2.5 mg/mL concentration
How draw volume changes if you vary the dose at the standard 5 mg + 2 mL reconstitution.
| Dose | Volume | IU draw (100u) |
|---|---|---|
| 0.5 mg | 0.2 mL | 20 IU |
| 1 mg Std | 0.4 mL | 40 IU |
| 1.5 mg | 0.6 mL | 60 IU |
| 2 mg | 0.8 mL | 80 IU |
| 3 mg | 1.2 mL | 120 IU |
Reconstitution steps
- Wipe the top of both the Snap-8 (Argireline) vial and the bacteriostatic water vial with alcohol swabs.
- Draw 2 mL of bacteriostatic water into a sterile syringe.
- Inject the water slowly down the inside glass wall of the Snap-8 (Argireline) 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
- Snap-8 (Argireline) 5 mg lyophilized vial
- 2 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 Snap-8 (Argireline) vial?
For the standard ASCEND research protocol, add 2 mL of bacteriostatic water to a 5 mg Snap-8 (Argireline) vial. This yields 2.5 mg/mL.
What concentration does 2 mL BAC water give for 5 mg Snap-8 (Argireline)?
A 5 mg Snap-8 (Argireline) vial reconstituted with 2 mL of bacteriostatic water yields 2.5 mg/mL. A 1 mg dose then requires 0.4 mL (40 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for Snap-8 (Argireline)?
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 Snap-8 (Argireline) 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 Snap-8 (Argireline)?
For a 1 mg dose (40 IU draw), a 50-unit (0.5 mL) or 100-unit U-100 insulin syringe is appropriate.
