Individual results vary. These were separate trials, not a direct comparison. Retatrutide remains investigational.

01 / YOUR MEASUREMENTS
Small numbers. Useful perspective.
Weight & height check (BMI)
Enter your height and weight to see your Body Mass Index and whether it falls in the underweight, healthy, overweight or obese range. This is a general screening tool only — it doesn't account for muscle, age or body composition, and it isn't medical advice.

Waist-to-height ratio
Another general screening measure: measure your waist at the belly button and compare it to your height. A common rule of thumb is to keep your waist under half your height. General information only — not medical advice.
— RATIO

Reconstitution calculator
Lab-prep math for research solutions: enter the total milligrams in a vial and how much bacteriostatic water you add, and it shows the resulting concentration and the syringe math. Purely informational — for laboratory research only, not dosing or personal-use guidance.
