Mixing and storage

For a 5 mg vial, add 2 mL bacteriostatic water slowly and swirl: 2.5 mg per mL, so 1 mg is 40 units and 2 mg is 80 units. For a 10 mg vial with 2 mL: 5 mg per mL, so 2 mg is 40 units. For a 20 mg vial, use 4 mL: 5 mg per mL, 2 mg is 40 units. Keep powder cool and dark; after mixing, fridge and use within 28 days.
