Brief 3C-P Information
by Erowid
June 2004

Citation:   Erowid F. "3C-P Information". Erowid Extracts. Jun 2004;6:17.

3C-P is mentioned briefly in PiHKAL as the unexplored "amphetamine homologue" of proscaline (#140, or "P"). Very little is known about this substance and it should not be considered safe for human ingestion.

Data Confidence:
Very tentative.


Stimulant, possible psychedelic or empathogen.

Exotic / Very Rare

Very rough estimates. Threshold 5-10 mg; Medium 10-40 mg; Strong 40+ mg.

Probably long, 8 - 16 hours.

Unknown. Humans have survived ingestion of up to 50 mg oral.

Through research chemical market. Sold semi-publicly in late 2003 through at least one source.

Field Tests:
Marquis reagent reacts orange with the 3C-P sold in 2003.

We know of a dozen or so reports of human 3C-P ingestion. Various authors, unverified provenance:
8 mg: "I want to call this a threshold"; 16 mg: "something like 5 mg of Adderall"; 20 mg: "overall, the experience was very mild"; 30 mg: "+3 euphoric period lasting 3 hours-ish and then a +2 psychedelic amphetamine feeling for another 12+ hours... unable to sleep (and kind of tired) is pretty annoying"; 30 mg: "for me, 30 mg was perfect... [but] I should reiterate that the duration was annoying"; 40 mg: "an average dose".
