Summary
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 basis. Dosing for 4FβPPP is not established in peerβreviewed literature; ranges below are compiled from scattered user reports and classβbyβanalogy to Ξ±βPPP/MPPP. Always allergy test (1β2 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.)
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Oral | 15-30mg | 30-50mg | 50-70mg | 70mg+ |
| Insufflated | 5-15mg | 15-30mg | 30-45mg | 45mg+ |
Onset, Duration & After-effects
| ROA | Onset | Peak | Offset | Total |
|---|---|---|---|---|
| Oral | 20-60 min | 0.5-2 hrs | 1-2 hrs | 3-6 hrs |
| Insufflated | 5-15 min | 0.5-2 hrs | 1-2 hrs | 3-6 hrs |

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 4F-PPP there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
4F-PPP Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 5-10 Β· light 15-30 Β· common 30-50 Β· strong 50-70 Β· heavy 70+ Insufflated dose (mg): threshold 3-5 Β· light 5-15 Β· common 15-30 Β· strong 30-45 Β· heavy 45+ Oral duration: onset 0.33-1h Β· peak 0.5-2h Β· offset 1-2h Β· total 3-6h Β· after-effects 2-12h Insufflated duration: onset 5-15m Β· peak 0.5-2h Β· offset 1-2h Β· total 3-6h Β· after-effects 2-12h 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
Tolerance Decay
Acute tolerance: develops within a single session β the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Model reflects typical stimulant patterns inferred from user reports across pyrrolidinophenones: tolerance builds rapidly over days of consecutive use and decays over 2β4 weeks. Data quality is low; conservative spacing (β₯2β3 weeks between sessions) is prudent.
