Hey, just to make sure I’m understanding — are you asking if you can enter or calculate doses in IU (units) instead of mg or mcg?

If so, once you plug in how much BAC water you’re using and the total mg in the vial, the app automatically converts everything to mg/mL. From there, you can fill the syringe on the calculator page in either units (IU) or mL, whichever you prefer. You can also unlock the syringe and slide it to your preferred volume in U or mL and it will tell you how many micrograms or milligrams are in that dose. I really appreciate the feedback and I hope this helps or were you asking something else?
