Peptide reconstitution chart
How much is in each 10 units after you mix a vial, for common vial sizes and water amounts. All values are for U-100 insulin syringes, where 10 units = 0.1 mL.
mg in every 10 units
| Vial | 1 mL water | 2 mL water | 3 mL water |
|---|---|---|---|
| 2 mg | 0.2 mg | 0.1 mg | 0.067 mg |
| 5 mg | 0.5 mg | 0.25 mg | 0.167 mg |
| 10 mg | 1 mg | 0.5 mg | 0.333 mg |
| 15 mg | 1.5 mg | 0.75 mg | 0.5 mg |
| 20 mg | 2 mg | 1 mg | 0.667 mg |
| 30 mg | 3 mg | 1.5 mg | 1 mg |
Units for every 100 mcg (0.1 mg)
| Vial | 1 mL water | 2 mL water | 3 mL water |
|---|---|---|---|
| 2 mg | 5 u | 10 u | 15 u |
| 5 mg | 2 u | 4 u | 6 u |
| 10 mg | 1 u | 2 u | 3 u |
| 15 mg | 0.7 u | 1.3 u | 2 u |
| 20 mg | 0.5 u | 1 u | 1.5 u |
| 30 mg | 0.3 u | 0.7 u | 1 u |
The formula
Strength (mg per mL) = mg in the vial ÷ mL of water. Units to draw = your dose in mg ÷ strength × 100. Example: 10 mg with 2 mL is 5 mg per mL, so a 0.25 mg dose is 0.25 ÷ 5 × 100 = 5 units.
Answer 4 quick taps and see exactly how many units to draw for your dose, on your syringe.
Calculate my unitsQuestions
How do I read this chart?
Find your vial size on the left and the water you added at the top. The cell shows how much is in 10 units, or how many units hold 100 mcg.
Does adding more water change the dose?
No. More water spreads the same amount over more volume, so each dose takes more units. The amount you inject stays the same.
Is this a dosing recommendation?
No. It is arithmetic for a mixed vial. Your dose comes from your prescriber.
