Works out concentration from a vial's peptide content and the bacteriostatic water added, then shows the syringe draw for a target dose — with a live 1 mL (100-unit insulin) and 2 mL syringe readout. All calculation happens in your browser; nothing here is sent anywhere.
Not medical advice. This tool does arithmetic on the numbers you enter — it has no way to verify your vial's actual labelled content, your syringe's actual markings, or whether a given dose is appropriate for you. Always read your vial and syringe against what you enter here before drawing anything, and see the dosing & safety guide.

1 mL insulin syringe (100 units)
Enter values above
Standard insulin syringe, marked in units. 100 units = 1 mL = 20 units per 0.2 mL major line.
2 mL syringe
Enter values above
Standard Luer syringe marked in 0.1 mL graduations, no unit markings.
If a reading exceeds a syringe's barrel, the fill shows full red rather than overflowing — switch to the larger syringe, or reconstitute with more water to bring the draw volume back within range.
