Mixing 10 mg TB-500
Adding 2 mL of bacteriostatic water to a 10 mg vial of TB-500 gives 5 mg/mL: each 10 units on a U-100 insulin syringe holds 500 mcg. With 1 mL it's 10 mg/mL (1,000 mcg per 10 units); with 3 mL, 3.333 mg/mL (333.3 mcg per 10 units). More water makes small amounts easier to measure.
