Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 4-HO-MPMI there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
4-HO-MPMI Source: SubstanceSearch (substancesearch.com) Oral dose (µg): threshold 500-750ug · light 750ug-1mg · common 1-2mg Oral duration: onset 0.25-1h · peak 6-8h · total 6-8h 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 ~ 1500 µg (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.
