Dose & Lose
Free GLP-1 tools
Small tools for the questions a GLP-1 medicine raises: how much of it is still in your body and how long it takes to clear, what each label's dose steps look like, what the published references say about water and protein, how much weight you have lost as a percentage, and how much protein common foods bring.
Each tool shows its method and names its sources, so you can check the arithmetic yourself. Everything runs in your browser. Nothing you type is sent anywhere, and you don't need an account.
The tools explain numbers; they never recommend a dose, a schedule or a change to either. That is your prescriber's decision.
