The PsychonautWiki Journal logging app doesn't include every substance. To track Theobromine there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
Theobromine Source: SubstanceSearch (substancesearch.com) Oral dose (mg): light 100-200 · common 200-300 · strong 300-600 · heavy 2000+ Oral duration: onset 2-3h · peak 2-3h · total 30-40h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 250 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
