Aliases: 4f-3m-ฮฑ-pvp, 4f-3me-ฮฑ-pvp, 3-m-4-f-ฮฑ-pvp, 3-methyl-4f-pvp, 4-fluoro-3-methyl-ฮฑ-pyrrolidinopentiophenone
Summary
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 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.)
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Oral | 5-15mg | 15-30mg | 30-45mg | 45mg+ |
| Sublingual | 5-15mg | 15-30mg | 30-45mg | 45mg+ |
| Insufflated | 5-20mg | 20-40mg | 40-60mg | 60mg+ |
| Smoked | 3-10mg | 10-15mg | 15-20mg | 20mg+ |
Onset, Duration & After-effects
| ROA | Onset | Peak | Offset | Total |
|---|---|---|---|---|
| Oral | 15-30 min | 30-90 min | 1-2 hrs | 3-5 hrs |
| Insufflated | 5-10 min | 30-90 min | 60 min | 1.58-2.67 hrs |
| Smoked | <1-2 min | 2-10 min | 30-45 min | 60-90 min |

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track MFPVP there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
MFPVP Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 5 ยท light 5-15 ยท common 15-30 ยท strong 30-45 ยท heavy 45+ Sublingual dose (mg): threshold 5 ยท light 5-15 ยท common 15-30 ยท strong 30-45 ยท heavy 45+ Insufflated dose (mg): threshold 5 ยท light 5-20 ยท common 20-40 ยท strong 40-60 ยท heavy 60+ Smoked dose (mg): threshold 3 ยท light 3-10 ยท common 10-15 ยท strong 15-20 ยท heavy 20+ Oral duration: onset 15-30m ยท peak 0.5-1.5h ยท offset 1-2h ยท total 3-5h ยท after-effects 2-6h Sublingual duration: after-effects 2-6h Insufflated duration: onset 5-10m ยท peak 0.5-1.5h ยท offset 1h ยท total 1.58-2.67h ยท after-effects 2-6h Smoked duration: onset <1-2m ยท peak 2-10m ยท offset 30-45m ยท total 1-1.5h ยท after-effects 2-6h 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 ~ 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
Tolerance Decay
Acute tolerance: develops within a single session โ the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Tolerance data for MFPVP are limited; parameters extrapolated from ฮฑโPVP/MDPV patterns and community reports; use as a conservative planning guide only.
