40 mg/mL · 40,000 mcg/mL · 400 mcg per U-100 unit

60 mg vial + 1.5 mL bacteriostatic water

A 60 mg vial reconstituted with 1.5 mL comes to 40 mg/mL. Every unit on a U-100 insulin syringe then carries 400 mcg, so 5 mg is 12.5 units (0.13 mL) and the vial holds 12 draws of that size.

Same concentration, different vial

These pairs also come to 40 mg/mL, so their unit counts match this page exactly; only the number of draws per vial differs: 20 mg + 0.5 mL.

60 mg + 1.5 mL questions

What concentration is 60 mg in 1.5 mL?

60 mg divided by 1.5 mL is 40 mg/mL, which is 40,000 mcg/mL. On a U-100 syringe each unit holds 0.01 mL, so one unit carries 400 mcg.

How many units is 5 mg from a 60 mg vial with 1.5 mL?

5000 mcg divided by 40,000 mcg/mL is 0.13 mL, which is 12.5 units on a U-100 syringe and 5 units on a U-40 syringe. The vial holds 12 draws of that size.

What if I add 2 mL instead of 1.5 mL to the 60 mg vial?

The mass stays 60 mg. With 2 mL the concentration is 30 mg/mL instead of 40 mg/mL, so the same amount per draw needs more units: 5 mg becomes 16.7 units instead of 12.5.

Does a 60 mg vial hold 1.5 mL?

Usually. Most lyophilized peptide vials are 2 mL or 3 mL glass, and 1.5 mL fits with room to swirl. Check the vial if it is an unusually small format.
