DRAW & DOSE CALCULATOR
Work out exactly how much reconstituted peptide solution to draw into your syringe. Choose your dose, vial strength, and how much bacteriostatic water you added — the calculator does the rest and shows the fill mark on a U-100 syringe.
Dose of Peptide
The amount you want to inject each time.
Peptide Strength
The total amount stated on your vial.
Bacteriostatic Water
How much water you reconstituted with — sets the concentration.
Result
Draw up 0.5 mL (50 units) to deliver a 5 mg dose.
How to use the calculator
Pick the amount of peptide you want in each injection (for example 0.25 mg = 250 mcg).
Select the total milligrams printed on your vial, e.g. 5 mg or 10 mg.
Enter how many mL of bacteriostatic water you used to reconstitute the powder.
The meter shows the exact unit mark to draw to on a U-100 insulin syringe (1 mL = 100 units).
Worked example
Suppose your vial is 5 mg and you reconstitute it with 3 mL of bacteriostatic water. That gives a concentration of 5 mg ÷ 3 mL ≈ 1.67 mg/mL. To inject a 250 mcg (0.25 mg) dose you divide 0.25 mg by 1.67 mg/mL ≈ 0.15 mL. Because a U-100 syringe has 100 units per mL, that is 15 units — so you draw up to the 15-unit mark.
