Peptide LibraryHow many units is 10 mg?
10 mg is 200 units (more than one 1 mL syringe) on a U-100 insulin syringe when the solution is 5 mg/mL (a 10 mg vial mixed with 2 mL of water), which is 2 mL. The number of units depends on the concentration: from 100 units at 10 mg/mL to 400 units at 2.5 mg/mL.

10 mg at common concentrations
| Vial and water | Concentration | Volume | U-100 units | U-40 units |
|---|---|---|---|---|
| 5 mg in 2 mL | 2.5 mg/mL | 4 mL | 400 units (more than one 1 mL syringe) | 160 units (more than one 1 mL syringe) |
| 10 mg in 3 mL | 3.33 mg/mL | 3 mL | 300 units (more than one 1 mL syringe) | 120 units (more than one 1 mL syringe) |
| 10 mg in 2 mL | 5 mg/mL | 2 mL | 200 units (more than one 1 mL syringe) | 80 units |
| 15 mg in 2 mL | 7.5 mg/mL | 1.333 mL | 133.3 units (more than one 1 mL syringe) | 53.3 units |
| 10 mg in 1 mL | 10 mg/mL | 1 mL | 100 units | 40 units |
Concentration is the mg in the vial divided by the mL of water added. Units measure volume: 100 units fill 1 mL on a U-100 syringe.

Common questions
Do insulin syringe units depend on the peptide?
No. Units are marks of volume: on a U-100 syringe, 100 units fill 1 mL. What changes between peptides is the concentration of the solution, which is the mg in the vial divided by the mL of water added.
What if my syringe is U-40?
A U-40 syringe has 40 marks per mL, so the same volume reads as 2.5 times fewer units. Read the scale printed on the syringe and use the matching column.
Is 10 mg a typical amount?
This page converts 10 mg because people search for that number. It is not a suggested amount; Peptide Library does not recommend doses. The library's profiles list what published studies used, with sources.
