Mixing 20 mg Retatrutide
Adding 2 mL of bacteriostatic water to a 20 mg vial of Retatrutide gives 10 mg/mL: each 10 units on a U-100 insulin syringe holds 1,000 mcg. With 1 mL it's 20 mg/mL (2,000 mcg per 10 units); with 3 mL, 6.667 mg/mL (666.7 mcg per 10 units). More water makes small amounts easier to measure.
