    Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 3 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 rapidly after a single use
    Reset 7–14 days for baseline

    Tolerance Decay

    Half tolerance 7d Baseline ~10d

    Animal data show rapid tolerance to head-twitch with repeated dosing; users commonly report diminished effects for several days after use with partial recovery by ~3 days and near-baseline after ~10–14 days. Cross-tolerance with classic psychedelics is expected given shared 5‑HT2A agonism, but human quantification is lacking.
