60 mg vial + 2.5 mL bacteriostatic water
A 60 mg vial reconstituted with 2.5 mL comes to 24 mg/mL. Every unit on a U-100 insulin syringe then carries 240 mcg, so 5 mg is 20.8 units (0.21 mL) and the vial holds 12 draws of that size.

60 mg + 2.5 mL questions
What concentration is 60 mg in 2.5 mL?
60 mg divided by 2.5 mL is 24 mg/mL, which is 24,000 mcg/mL. On a U-100 syringe each unit holds 0.01 mL, so one unit carries 240 mcg.
How many units is 5 mg from a 60 mg vial with 2.5 mL?
5000 mcg divided by 24,000 mcg/mL is 0.21 mL, which is 20.8 units on a U-100 syringe and 8.3 units on a U-40 syringe. The vial holds 12 draws of that size.
What if I add 3 mL instead of 2.5 mL to the 60 mg vial?
The mass stays 60 mg. With 3 mL the concentration is 20 mg/mL instead of 24 mg/mL, so the same amount per draw needs more units: 5 mg becomes 25 units instead of 20.8.
Does a 60 mg vial hold 2.5 mL?
Usually. Most lyophilized peptide vials are 2 mL or 3 mL glass, and 2.5 mL fits with room to swirl. Check the vial if it is an unusually small format.
