There is no single "correct" amount — the water volume you add sets the concentration. For a 10 mg retatrutide vial, 1 ml of bacteriostatic water gives 10 mg/ml, 2 ml gives 5 mg/ml, and 5 ml gives 2 mg/ml. Adding 1–2 ml is common because it keeps the draw volume small. Use the calculator below to see the exact concentration and units for the amount you choose.
Adjust the vial size and bacteriostatic water to see the exact concentration and units. Research math only.
Units assume a U-100 syringe (100 units = 1 ml). This is research math only, not dosing or medical advice.
Round physical measurements carefully and follow your lab protocol.
Everything here is for laboratory research use only. It describes bacteriostatic water and reconstitution arithmetic — not dosing, and not medical guidance. If your goal is treating something in yourself, that's a job for a licensed clinician.
