Why Use a Peptide Calculator?

Peptides arrive as a freeze-dried powder and must be reconstituted with bacteriostatic water before research. Getting the math right is critical: too much water and your solution becomes diluted, too little and each unit on the syringe delivers more peptide than intended. This calculator converts milligrams to milliliters and insulin units automatically so you can plan research accurately.

How the Calculator Works

Select your syringe size (0.3 mL, 0.5 mL, or 1.0 mL), enter the peptide amount in your vial, the volume of BAC water used, and your desired dose. The tool instantly shows concentration, volume per dose, units on the syringe, and approximate doses per vial.

Step-by-Step Peptide Reconstitution

1. Use sterile bacteriostatic water (not tap or distilled).
2. Slowly add the chosen volume of BAC water into the lyophilized peptide vial.
3. Gently swirl until fully dissolved (do not shake).
4. Refrigerate reconstituted vials at 2–8 °C and use within 20–30 days.
