    WARNING: No human experience reports, pharmacological studies, or toxicological data exist for 4F-PPP. This compound has only been identified as an analytical reference standard. The parent compound Ξ±-PPP shows reinforcing effects in animal models.

    Dose Information dose.wiki Drugs.Wiki

    Dose basis. Dosing for 4F‑PPP is not established in peer‑reviewed literature; ranges below are compiled from scattered user reports and class‑by‑analogy to α‑PPP/MPPP. Always allergy test (1–2 mg) and titrate by small increments using a milligram scale or volumetric dosing. Expect significant batch-to-batch variability and frequent mislabeling in this market; drug checking is strongly advised. Intranasal use of pyrrolidinophenones and related stimulants is often caustic and damaging to nasal tissue; severe burn/drip and congestion are widely reported for close analogs (e.g., pBPPP). Start low, allow full onset before re-dosing, and avoid repeated lines to reduce mucosal injury. (Dose figures and this note are from Drugs.Wiki.)

    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 ~ 40 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 7d Half tolerance 14d Baseline ~30d

    Model reflects typical stimulant patterns inferred from user reports across pyrrolidinophenones: tolerance builds rapidly over days of consecutive use and decays over 2–4 weeks. Data quality is low; conservative spacing (β‰₯2–3 weeks between sessions) is prudent.
