Library

43 compounds, with half-lives, titration ladders and sources. Every dose carries a tag saying where it came from, an approved label, a clinical trial, or community practice with nothing behind it.

Your own compounds

Anything the library does not carry. Your entries work everywhere a built-in one does, protocols, logging, stock and cost, but they are never shown as researched: dose ranges are tagged as yours, there are no citations, and no curve is drawn unless you give a half-life. You can also add one straight from any compound dropdown.
