24 mg vial + 1.5 mL bacteriostatic water: units chart
A 24 mg vial mixed with 1.5 mL of bacteriostatic water holds 16,000 mcg per mL. This is a strong mix: each unit holds 160 mcg, so small doses take up only a few units and are harder to measure. More water would spread them out.
Units to draw
1.6units
Draw 1.6 units on a U-100 syringe, just below the 2-unit mark.
Warning: At 1.6 units this dose is hard to measure. Add more water when you mix the vial so the dose fills at least 2 units.

Worked example: 1,500 mcg
- Convert the vial amount to mcg: 24 mg × 1,000 = 24,000 mcg
- Concentration: 24,000 mcg ÷ 1.5 mL = 16,000 mcg/mL (16 mg/mL)
- Volume to draw: 1,500 mcg ÷ 16,000 mcg/mL = 0.0938 mL
- Units to draw: 0.0938 mL × 100 units/mL = 9.4 units
- Amount in each unit: 16,000 mcg/mL ÷ 100 units/mL = 160 mcg per unit (0.16 mg)
- Doses in the vial: 24,000 mcg ÷ 1,500 mcg = 16 full doses
Draw 9.4 units on a U-100 syringe, between the 8- and 10-unit marks, closer to 10. The same 1,500 mcg dose is 6.3 units with 1 mL of water and 12.5 units with 2 mL of water, compared with 9.4 units with 1.5 mL.
Frequently asked questions
What is the concentration of a 24 mg vial with 1.5 mL of water?
A 24 mg vial mixed with 1.5 mL of water holds 16,000 mcg per mL. Each unit on a U-100 syringe holds 160 mcg.
How many units is 1,500 mcg with a 24 mg vial and 1.5 mL of water?
It is 9.4 units on a U-100 syringe, which is 0.0938 mL of the mixed liquid.
What is the smallest dose you can measure well with a 24 mg vial and 1.5 mL of water?
About 320 mcg, which fills 2 units on a U-100 syringe. Smaller amounts are hard to read; a vial mixed with more water spreads them over more units.
What is the largest dose that fits a 1 mL syringe with a 24 mg vial and 1.5 mL of water?
16,000 mcg, which fills all 100 units of a 1 mL U-100 syringe. Larger doses need more than one draw or a stronger mix.
How many doses does a 24 mg vial with 1.5 mL of water give?
Divide 24,000 mcg by your dose and round down: 16 full doses of 1,500 mcg, or 12 of 2,000 mcg.
