Estimated medication levels

Explore our Plotter to track how your GLP-1 Receptor Agonist concentration changes over time. This tool also acts as a dose calculator, letting you predict the drug levels in your system for different dosing schedules.

Disclaimer: Individual responses can vary widely, and factors like metabolism and physiology differ from person to person. We’ve designed this calculator using publicly available data, but the estimated half-lives may not be exact for everyone. Please use the tool responsibly and at your own risk.

How the GLP-1 Tracker came about

I'm also on my own GLP-1 weight loss journey and I wanted a way to track my progress. I tried other apps out there and nothing did everything I wanted it do do, so I built my own! So this tool genuinely is something that has been built by a member of the community, for the community! I appreciate this might not have everything other people need, but if it's a useful feature then I'll build that too!
