| 5 mg | 2 mL | 2,500 mcg/mL |
| 10 mg | 2 - 3 mL | 3,333 - 5,000 mcg/mL |
| 15 mg | 3 mL | 5,000 mcg/mL |
| 20 mg | 4 mL | 5,000 mcg/mL |
GUIDE
How to Reconstitute Peptides
Prepare
Clean the vial stopper and BAC water vial with an alcohol swab. Allow to dry. Work on a clean surface.
Draw Water
Using an insulin syringe, draw your calculated volume of bacteriostatic water. Remove air bubbles by flicking the syringe.
Add to Vial
Insert the needle through the stopper at an angle. Let the water slide down the inside wall of the vial. Do not spray directly onto the powder.
Dissolve
Gently swirl the vial in circular motions until the powder is fully dissolved. Do not shake — this can damage the peptide structure.
Store
Reconstituted peptides should be stored at 2-8°C (refrigerator). Use within 30 days. Do not freeze once reconstituted.
Storage Guidelines
- Lyophilized (unreconstituted): -20°C for up to 24 months
- Reconstituted: 2-8°C, use within 30 days
- Avoid repeated freeze-thaw cycles
- Protect from direct light
- Always use bacteriostatic water (not sterile water) for multi-dose vials
Unit Conversions
| From | To | Conversion |
|---|---|---|
| 1 mg | mcg | 1,000 mcg |
| 1 mL | IU (insulin syringe) | 100 IU |
| 1 IU (insulin syringe) | mL | 0.01 mL |
