Mixing and storage

For a 5 mg vial, add 2 mL bacteriostatic water slowly down the side and swirl: 2.5 mg per mL, so 100 mcg is 4 units, 200 mcg is 8 units and 300 mcg is 12 units. A 10 mg vial with 2 mL gives 5 mg per mL, so 200 mcg is 4 units. Keep powder cool and dark; after mixing, fridge and use within 28 days.
