Mix your vial
Type the mg on your vial. Type the water you put in. Now the tool knows how strong it is.
Type in your vial and your dose. Watch a real syringe fill to the exact line you draw to.

Type the mg on your vial. Type the water you put in. Now the tool knows how strong it is.
Type the dose you want. Pick mcg or mg. Then pick your syringe. Most people use U-100.
The syringe fills to the right spot. Pull the plunger to that line. That is your dose.
Every number the tool shows comes from these. Nothing hidden.
A 5 mg vial with 2 mL of water is 2.5 mg/mL. A 250 mcg dose is 0.10 mL, which reads as 10 units on a U-100 syringe, and the vial holds 20 doses.
Divide the peptide in the vial (mg) by the bacteriostatic water you added (mL) to get the concentration in mg/mL. Divide your target dose by that concentration to get the volume to draw in mL, then multiply by your syringe scale (100 for a U-100 syringe) to get the units on the barrel.
That is your choice, and it only changes the concentration, not the total peptide. More water means a lower concentration and more units drawn per dose (easier to measure small amounts); less water means the opposite. This tool shows the result for whatever amount you enter.
A standard U-100 insulin syringe has 100 units per mL marked on the barrel, so 0.25 mL reads as 25 units. This calculator converts your dose volume into those tick marks so you know exactly where to draw to.
Divide the total peptide in the vial by your dose. A 5 mg vial dosed at 250 mcg (0.25 mg) gives 20 doses. The calculator shows this automatically.
