    The PsychonautWiki Journal logging app doesn't include every substance. To track D2PM there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

    ⬇ Download import file Import this file as custom substances and you get "D2PM (Substance Search)" with every route's full dose ladder and timeline, no typing. Works on iOS and Android (v15+); the format is confirmed by the app's developer. The manual values below work for older versions.

Source: SubstanceSearch (substancesearch.com)

Oral dose (mg): light 15-20 · common 20-35 · strong 35-50 · heavy 50+

Oral duration: onset 20-30m · peak 2-5h · total 2-5h · after-effects 1-6h

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 ~ 27.5 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.
