FAQ
- How much BAC water for 20 mg retatrutide?
- Most people reconstitute with 1–3 mL bacteriostatic water. More water lowers concentration so each unit on a U-100 syringe represents less peptide. Use the table on this page to compare 1, 2, and 3 mL.
- How many units is 2 mg retatrutide?
- Units depend on how much BAC water you added. Enter your vial size and water volume in the calculator; it converts mg to mcg and shows the U-100 unit line.
- Can I use sterile water instead of BAC water?
- Bacteriostatic water is common for multi-dose vials because of benzyl alcohol. See our BAC vs sterile water guide for storage windows.
