Summary
4-Cl-PPP (4-chloro-Ξ±-pyrrolidinopropiophenone) is an obscure designer stimulant with minimal human data beyond forum reports. Para-chloro amphetamine analogues have shown serotonergic neurotoxicity in animal studies, raising concerns about potential long-term risks. Users report rapid tolerance formation (within 1-2 days), brief euphoria followed by pronounced compulsion to redose, severe insomnia, and an unpleasant crash.
Dose Information
Dose basis. Dose ranges are compiled from scattered user reports; no controlled human data identified. Given unknown potency and batch variability for obscure pyrrolidinophenones, start at the very low end with an accurate milligram scale and avoid redosing until full onset is assessed. Reference doses on community sites are not guarantees of safety and should be treated conservatively. Pyrrolidinophenones and related stimulants are frequently reported as caustic to nasal tissue; repeated lines can cause chemical burns and prolonged congestion. Prefer oral ROA to reduce local damage; if insufflating, use tiny amounts, allow long intervals, and perform gentle nasal rinses with sterile saline hours later (never immediately after dosing to avoid deeper spread). Community HR sources also caution that some stimulants are notably corrosive to septal tissue when snorted. (Dose figures and this note are from Drugs.Wiki.)
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Oral | 10-20mg | 20-40mg | 40-60mg | 60mg+ |
| Insufflated | 5-10mg | 10-25mg | 25-40mg | 40mg+ |
Onset, Duration & After-effects
| ROA | Onset | Peak | Offset | Total |
|---|---|---|---|---|
| Oral | 15-40 min | 1-2 hrs | 1-2 hrs | 2.25-4.67 hrs |
| Insufflated | 5-10 min | 1-2 hrs | 1-2 hrs | 2.08-4.17 hrs |

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 4-Cl-PPP there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
4-Cl-PPP Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 5 Β· light 10-20 Β· common 20-40 Β· strong 40-60 Β· heavy 60+ Insufflated dose (mg): threshold 3 Β· light 5-10 Β· common 10-25 Β· strong 25-40 Β· heavy 40+ Oral duration: onset 15-40m Β· peak 1-2h Β· offset 1-2h Β· total 2.25-4.67h Β· after-effects 2-6h Insufflated duration: onset 5-10m Β· peak 1-2h Β· offset 1-2h Β· total 2.08-4.17h Β· 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 ~ 30 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.
Pattern extrapolated from stimulant pyrrolidinophenones (MDPV/Ξ±βPVP class), where consecutiveβday use rapidly blunts rewarding effects and increases adverse effects; very lowβquality evidence from user reports, not controlled studies.
