Calculators & Tools
Two calculators to help you understand BMI and what weight-loss percentages from retatrutide clinical trials would mean for your starting weight.
These tools are for educational purposes only. They do not predict your individual outcome and are not medical advice. Retatrutide is investigational and not FDA approved.
BMI Calculator
Body mass index (BMI) is used in clinical trials to define eligibility. Most retatrutide trials required BMI ≥ 30, or ≥ 27 with a weight-related comorbidity.
Weight-Loss Percentage Calculator
Enter your current weight to see what the mean weight-loss percentages reported in retatrutide Phase 2 and Phase 3 trials would translate to in pounds and kilograms.
Medical disclaimer: These calculators are educational tools only. BMI is a population-level screening metric with well-documented limitations. Weight-loss percentages are trial means from specific study populations and do not predict individual outcomes. Retatrutide is an investigational drug that has not been approved by the FDA.
