If you’ve just received a peptide vial and a bottle of bacteriostatic water, you might be wondering: how much do I add?
The short answer: it depends on the concentration your protocol calls for. Here’s how to figure it out quickly.
The Simple Formula
Volume of BAC Water = Peptide Amount (mg) ÷ Target Concentration (mg/mL)
Example:
You have a 5 mg peptide vial and want 1 mg/mL → add 5 mL of BAC water.
You have a 5 mg peptide vial and want 2 mg/mL → add 2.5 mL of BAC water.
Quick Reference Table
| Peptide Amount | Target Concentration | BAC Water to Add |
|---|---|---|
| 2 mg | 1 mg/mL | 2.0 mL |
| 5 mg | 1 mg/mL | 5.0 mL |
| 5 mg | 2 mg/mL | 2.5 mL |
| 10 mg | 1 mg/mL | 10.0 mL |
| 10 mg | 2 mg/mL | 5.0 mL |
Values shown are for calculation reference only. Always follow your specific research protocol.
Which Vial Size Do You Need?
- Adding less than 10 mL → a 10 mL vial works fine
- Adding more than 10 mL → go with a 30 mL vial
Tips
- Add BAC water slowly along the side of the vial — don’t squirt directly onto the powder
- Swirl gently until dissolved — never shake or vortex
- Store according to your protocol requirements. See our storage guide for details.
- Always check your specific protocol for the recommended concentration
