Reconstitution Basics
Reconstitution is the process of adding bacteriostatic water (BAC water) to a lyophilized (freeze-dried) peptide vial to create a solution. The amount of water you add determines the concentration of the solution.
Using the Calculator
- Enter the total peptide amount listed on your vial (in milligrams)
- Enter how much bacteriostatic water you added (in milliliters)
- Enter your target dose (in micrograms)
- The calculator will show the exact volume to draw and the equivalent syringe units
Syringe Units
A standard 1mL insulin syringe has 100 unit markings. Each unit equals 0.01mL. So 50 units = 0.5mL, and 100 units = 1mL.
Handling Tips
- When reconstituting, aim the BAC water stream at the vial wall — not directly onto the lyophilized peptide
- Roll the vial gently between your palms to mix — never shake it
- Store reconstituted peptides in a refrigerator
