Summary
3F-PiHP is a fluorinated pyrrolidinophenone cathinone structurally related to ฮฑ-PiHP, ฮฑ-PHP, and 3F-PVP. It produces forceful stimulation, sociability, and euphoria but also frequent anxiety, paranoia, and powerful redosing compulsions, especially when vaped or insufflated. First identified in Sweden and Finland in mid-2019; limited pharmacological and toxicological data exist.
Dose Information
Dose basis. Freebase/salt confusion is common; vaping the salt can increase harsh decomposition byproducts and airway irritation per user reports. Doses below are aggregated from community reports; start lower and allergy test due to batch variability. Very caustic on nasal mucosa in many anecdotal reports; pre/post isotonic saline rinse and finely crushed powder reduce damage and pain. (Dose figures and this note are from Drugs.Wiki.)
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Smoked | 10-25mg | 25-50mg | 50-80mg | 80mg+ |
| Insufflated | 5-10mg | 10-25mg | 25-40mg | 40mg+ |
| Oral | 15-30mg | 30-60mg | 60-90mg | 90mg+ |
Onset, Duration & After-effects
| ROA | Onset | Comeup | Peak | Offset | Total |
|---|---|---|---|---|---|
| Smoked | <1-2 min | - | 12-60 min | 1-2 hrs | 2-4 hrs |
| Insufflated | 5-15 min | 5-10 min | 30-60 min | 1-2 hrs | 1.66-3.42 hrs |
| Oral | 20-40 min | 20-30 min | 1-2 hrs | 1-2 hrs | 2.66-5.17 hrs |

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 3F-PiHP there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

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 ~ 37.5 mg (Smoked).
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.
Pattern inferred from stimulant class and community reports: tolerance surges during binges and decays over days; significant interโindividual variability. Avoid multiโday runs; allow at least a week to partially reset. Data quality is anecdotal, not clinical.
