How Much BAC Water for IGF-1 LR3?
Quick answer: Add 1 mL of bacteriostatic water to a 1 mg IGF-1 LR3 vial. This yields a concentration of 1000 µg/mL. A standard 40 µg research dose then requires 0.04 mL (4 IU on a 100-unit insulin syringe).
Concentration by BAC water volume
Concentration and 40 µg draw volume at common BAC water volumes for a 1 mg vial.
| BAC water | Concentration | Dose volume | Draw |
|---|---|---|---|
| 1 mL Standard | 1000 µg/mL | 0.04 mL | 4 IU |
| 2 mL | 500 µg/mL | 0.08 mL | 8 IU |
| 3 mL | 333.33 µg/mL | 0.12 mL | 12 IU |
| 5 mL | 200 µg/mL | 0.2 mL | 20 IU |
Dose volume at the standard 1000 µg/mL concentration
How draw volume changes if you vary the dose at the standard 1 mg + 1 mL reconstitution.
| Dose | Volume | IU draw (100u) |
|---|---|---|
| 20 µg | 0.02 mL | 2 IU |
| 40 µg Std | 0.04 mL | 4 IU |
| 60 µg | 0.06 mL | 6 IU |
| 80 µg | 0.08 mL | 8 IU |
| 120 µg | 0.12 mL | 12 IU |
Reconstitution steps
- Wipe the top of both the IGF-1 LR3 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 IGF-1 LR3 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
- IGF-1 LR3 1 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 1 mg IGF-1 LR3 vial?
For the standard ASCEND research protocol, add 1 mL of bacteriostatic water to a 1 mg IGF-1 LR3 vial. This yields 1000 µg/mL.
What concentration does 1 mL BAC water give for 1 mg IGF-1 LR3?
A 1 mg IGF-1 LR3 vial reconstituted with 1 mL of bacteriostatic water yields 1000 µg/mL. A 40 µg dose then requires 0.04 mL (4 IU on a 100-unit insulin syringe).
Can I use sterile water instead of bacteriostatic water for IGF-1 LR3?
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 IGF-1 LR3 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 IGF-1 LR3?
For a 40 µg dose (4 IU draw), a 30-unit (0.3 mL) U-100 insulin syringe gives the finest resolution. A 100-unit syringe also works.
