    Summary dose.wiki

    Extremely limited human pharmacology and toxicology data exist. A 2014 patent describes its activity as a selective dopamine releasing agent. Reported as more serotonergic than 3-FPM but still primarily dopaminergic.

    Dose Information dose.wiki Drugs.Wiki

    Dose basis. Ranges are compiled from multiple user reports; individual sensitivity varies widely. Because the compound lacks formal human PK data and supply-chain purity is variable, start low (allergy 1–3 mg) and use a milligram scale. Redosing markedly increases adverse effects and insomnia. Source: multiple anecdotal reports on Reddit/Bluelight. Users consistently report severe nasal burn and prolonged mucosal irritation with this ROA; repeated lines greatly increase risk of epistaxis and septal injury. Saline before/after, fine powder, rotating nostrils, and long breaks are advised if one still chooses this route. Sources: user reports; general safer-snorting guidance. (Dose figures and this note are from Drugs.Wiki.)

    The PsychonautWiki Journal logging app doesn't include every substance. To track 3-CPM 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 "3-CPM (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.

Oral dose (mg): threshold 5 · light 10-25 · common 25-45 · strong 45-70 · heavy 70+
Insufflated dose (mg): threshold 3 · light 5-15 · common 15-30 · strong 30-45 · heavy 45+

Oral duration: onset 15-45m · come-up 0.5-1h · peak 1-2h · offset 2-3h · total 3.75-6.75h · after-effects 2-12h
Insufflated duration: onset 5-15m · come-up 15-30m · peak 1-2h · offset 1-2h · total 2.33-4.75h · after-effects 2-12h
Vaporized duration: onset 1-5m · come-up 5-15m · peak 0.5-1.5h · offset 1-2h · total 1.6-3.83h · after-effects 2-12h

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 ~ 35 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.

    Tolerance

    Build-up develops over days to weeks of regular use
    Reset 3–7 days for acute; 1–3 weeks for full reset

    Tolerance Decay

    Full tolerance 3d Half tolerance 7d Baseline ~30d

    Patterns are extrapolated from community reports for 3‑CPM and closely related phenylmorpholines (e.g., 3‑FPM). Tolerance seems to build rapidly over consecutive days, with partial reversal over 1–2 weeks and near-baseline after a month or more. Data quality is low/anecdotal.
