These curves are simplified half-life estimates, not bloodwork. They do not tell you what to take. Read the disclaimer.
The plotter runs in your browser. Saved protocols live in localStorage on this device under steroidplotter.protocols.v1. We do not have accounts, cookies for tracking, or a database of your protocols in v1.
Share links encode the protocol in the URL query string. Anyone with the link can see those numbers. Do not put identifying information in a protocol name if you share the URL.
Hosting is on Vercel, which receives normal request logs. That is not the same as storing your chart.
