How accurate is this muscle risk calculator?

It uses the same educational scoring model as GlowsProtocol's free assessment—based on medication, time on GLP-1, strength training, and protein intake. It is a wellness snapshot, not a clinical test or diagnosis.

Why is my score different from the full assessment?

The full assessment asks about your goals and can include facial-volume risk. This tool defaults to a muscle-retention focus and skips email capture—fewer inputs, faster result.

Does a high score mean I am losing muscle?

A higher score means your current habits and timeline suggest more attention to protein and resistance training may help—not that muscle loss has already happened. Track strength and talk with your clinician if you notice functional decline.

Which medications does the calculator support?

Ozempic, Wegovy, Mounjaro, Zepbound, and other GLP-1 or GIP/GLP-1 options. Select the closest match; the model adjusts for typical titration context, not your exact prescription details.

How does this relate to the Cell Reports Medicine 2026 review?

That review summarizes trial evidence that GLP-1 loss often includes lean tissue—not only fat. The calculator translates habit inputs into an educational awareness score so you can discuss protein and strength with your clinician—not a lab measurement.

Can the calculator score facial volume risk?

This page focuses on muscle retention inputs. The full free assessment at /signup adds facial-volume awareness scores and medication-aware weekly protocols when you want both dimensions.

If you're on semaglutide or tirzepatide and want a quick read on muscle-retention habits, most trackers log weight and injections without an interactive snapshot. This page offers a free calculator you can use right now.

Adjust four inputs—medication, time on therapy, weekly strength training, and protein—and get an instant muscle retention risk score (1–10). The math matches our free assessment; this is the lightweight version with no email step.
