    Summary dose.wiki

    Pharmacology data are scarce; in vitro transporter assays of related ฮฑ-PVP analogs suggest nanomolar NET/DAT inhibition. A 2022 forensic case reported fatal ventricular tachycardia with femoral blood 26 ng/mL, illustrating low LD50 margin. Fluorine substitution is predicted to raise metabolic stability, extending active phase relative to alkyl-only peers.

    Dose Information dose.wiki Drugs.Wiki

    Dose basis. Ranges are aggregated from user reports; significant batch-to-batch variability is possible. Always verify identity/purity with drug checking before dosing. Reported similar to oral but slightly faster onset; limited formal data. (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 ~ 22.5 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.

    Tolerance

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

    Tolerance Decay

    Tolerance data for MFPVP are limited; parameters extrapolated from ฮฑโ€‘PVP/MDPV patterns and community reports; use as a conservative planning guide only.
