Mixing 500 mg NAD+
Adding 2 mL of bacteriostatic water to a 500 mg vial of NAD+ gives 250 mg/mL: each 10 units on a U-100 insulin syringe holds 25,000 mcg. With 1 mL it's 500 mg/mL (50,000 mcg per 10 units); with 3 mL, 166.667 mg/mL (16,666.7 mcg per 10 units). More water makes small amounts easier to measure.
