Mixing and storage

Add 2 mL of bacteriostatic water to the 10 mg vial, slowly down the glass, and swirl until clear. That gives 5 mg per mL, so 0.6 mg is 0.12 mL, or 12 units on a U-100 syringe, and 2.4 mg is 48 units. Before mixing keep it cold and dark, in the freezer for long storage; after mixing keep it in the fridge at 2 to 8 C and use within 28 days.
