Reconstitution & Dosing Calculator
Enter vial size, reconstitution volume, and desired dose to compute exact syringe units, mL draw, and doses per vial — based on U-100 insulin syringe conventions.
Understanding units
A standard U-100 insulin syringe holds 1 mL (100 units). Each tick mark represents 1 unit (0.01 mL). When you reconstitute a peptide, the concentration determines how many units equal your desired dose.
Bacteriostatic water
More water means a more dilute solution — easier to measure small doses accurately. Less water means higher concentration — fewer units per injection. Common reconstitution volumes are 1–3 mL.
Storage after reconstitution
Once reconstituted with bacteriostatic water, most peptides should be refrigerated (2–8°C / 36–46°F) and are typically stable for 4–6 weeks. Unreconstituted peptides can be stored frozen for longer periods.
