30 mg/mL · 30,000 mcg/mL · 300 mcg per U-100 unit

60 mg vial + 2 mL bacteriostatic water

A 60 mg vial reconstituted with 2 mL comes to 30 mg/mL. Every unit on a U-100 insulin syringe then carries 300 mcg, so 5 mg is 16.7 units (0.17 mL) and the vial holds 12 draws of that size.

Same concentration, different vial

These pairs also come to 30 mg/mL, so their unit counts match this page exactly; only the number of draws per vial differs: 15 mg + 0.5 mL, 30 mg + 1 mL.

60 mg + 2 mL questions

What concentration is 60 mg in 2 mL?

60 mg divided by 2 mL is 30 mg/mL, which is 30,000 mcg/mL. On a U-100 syringe each unit holds 0.01 mL, so one unit carries 300 mcg.

How many units is 5 mg from a 60 mg vial with 2 mL?

5000 mcg divided by 30,000 mcg/mL is 0.17 mL, which is 16.7 units on a U-100 syringe and 6.7 units on a U-40 syringe. The vial holds 12 draws of that size.

What if I add 2.5 mL instead of 2 mL to the 60 mg vial?

The mass stays 60 mg. With 2.5 mL the concentration is 24 mg/mL instead of 30 mg/mL, so the same amount per draw needs more units: 5 mg becomes 20.8 units instead of 16.7.

Does a 60 mg vial hold 2 mL?

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