Peptide calculator

Enter your vial strength, how much bacteriostatic water you added, and your target research dose. The calculator shows the exact volume to draw on a standard U-100 insulin syringe.

Quick reference

• A U-100 insulin syringe holds 100 units = 1 mL; each tick is usually 1–2 units.
• More water = lower concentration = larger, easier-to-measure draws.
• Store reconstituted vials refrigerated and use within the recommended window.
