Units versus mL: the mistake that changes a dose tenfold
Why insulin-syringe units are a volume scale, how the same word gets used for three different things, and the arithmetic that keeps a 0.25 mL dose from becoming 2.5 mL.

What a population average means: reading the weight-loss projection
Where the STEP 1 and SURMOUNT-1 numbers come from, what the curve between week 0 and the endpoint is and is not, and the three reasons your own result will differ from the line.

How these calculators are built
Each tool is a small, pure function you can read in the formula panel underneath it. Inputs stay in your browser. Where a tool uses a published number (a trial endpoint, a label titration step, a dietary reference intake) the number is cited inline with a PubMed id, an FDA label or the originating body, and the assumptions note carries the date we last checked it.
What these calculators are not
They are arithmetic aids for medication a licensed prescriber has already prescribed. They do not pre-fill doses, they do not recommend a dose, and they are not built for research chemicals. Compounded GLP-1s are not FDA approved and are not interchangeable with brand products. If a result surprises you, stop and ask your prescriber or pharmacist before you draw anything up.
