Why Use Specialized GLP-1 Tools?
Managing weight loss on medications like Ozempic, Wegovy, Mounjaro, or Zepbound requires more than just a scale. Muscle preservation is critical during rapid weight loss, which is why our Protein Calculator accounts for the specific metabolic demands of GLP-1 users—calculating higher protein needs to prevent muscle loss while your body sheds fat.
Understanding the half-life of your medication helps prevent side effects and optimize timing. Our Medication Level Calculators help you visualize when medication levels peak in your system, allowing you to plan meals and activities around peak effectiveness and potential side effects.
Proper injection site rotation prevents lipodystrophy—a condition where repeated injections in the same spot cause fatty lumps or depressions that can reduce medication absorption. Our Injection Site Tracker provides a simple, personalized rotation schedule to keep your injections effective and your skin healthy.
All our tools are free to use and based on FDA-approved pharmacokinetic data and clinical research. Whether you're just starting your GLP-1 journey or optimizing your routine, these calculators help you make informed decisions about your health.
