Mixing 250 mg NAD+
Adding 2 mL of bacteriostatic water to a 250 mg vial of NAD+ gives 125 mg/mL: each 10 units on a U-100 insulin syringe holds 12,500 mcg. With 1 mL it's 250 mg/mL (25,000 mcg per 10 units); with 3 mL, 83.333 mg/mL (8,333.3 mcg per 10 units). More water makes small amounts easier to measure.
