Summary dose.wiki TripSit PsychonautWiki

3,5-Dimethoxy-4-propoxyamphetamine (also known as 3C-P or 3C-Proscaline) is a lesser-known psychedelic substance of the amphetamine class. Although its name suggests it may be related to the 2C-x family, this is not the case since it is the 3-Carbon analog of proscaline. The original synthesis date of 3C-P is unknown.

Perspectives

“It was fun, stimulating, warm and articulate, though ultimately light and subtle. There was little in the way of visuals, it felt like a long-lasting stimulant with a psychedelic edge.”

Erowid Experience Reports PsychonautWiki 3C-P

Tolerance

Build-up develops over days to weeks of regular use

Reset 3–7 days for acute; 1–3 weeks for full reset

Tolerance Decay

Full tolerance 1d Half tolerance 3d Baseline ~21d

As with other 5‑HT2A psychedelics, acute tolerance develops rapidly after a single session and tends to decay across one to two weeks. Data for 3C‑P specifically are anecdotal; estimates extrapolated from mescaline/2C/DOx literature.

Cross-Tolerances

Other serotonergic psychedelics (PEA and tryptamine classes)

DOx series (e.g., DOC, DOI)

Effects Erowid

Aggregated from 4 single-substance Erowid experience reports; 3 Erowid reports where another drug was taken too are left out

Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

Too few reports for bars: these effects come from 4 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Positive Effects 1

3 of 4 –

Adverse Effects 0

Also reported in combinations. In the 3 3C-P reports where another drug was taken too, 0 mention hospital, emergency services or an overdose, 0 a seizure and 1 psychosis (too few reports for percentages). In the 4 single-substance reports: 0, 0 and 0. These are not in the figures above: they cannot be put down to 3C-P alone, and a mention is not always something that happened to the writer.

Smooth, Fun, Therapeutic - A Nice Surprise positive exp #98979

T+0:00: 40mg (+/-2mg) consumed inside a rolling paper T+1:30: First alert? T+2:00: Definitely feeling something. Somewhat reminiscent of other not-so-smooth phenethylamine come-ups, notably 2C-P and the empathogens 5-APB & 6-APB. Some slight head tension.

Slow Burn positive exp #116112

Preface: I was debating whether or not this experience warranted a report, as it was overall pretty mild and I found myself struggling to describe the subtleties of it- if they were even remarkable enough to address.

Euphoric Stimmy Rollercoaster neutral exp #110307

There was a nice warm dry day and I decided to go on a bike ride and take 43mg of 3C-P. A day before that I've sampled it at 0.5-3mg to do an allergy test. The 3C-P powder that was obtained from a trusted and tested source appeared very similar looking to 3-FPM (3-FluoroPhenMetrazine - an entactogenic stimulant) - same...

Aucar, The Island Of Sailing Souls positive exp #111751

Since there is almost no information online about this chemical, we thought about sharing the very interesting experience we had with 3C-P. This trip happened we were on vacations, traveling through the beautiful Island of Chiloé, at the far south of the world.

All Trips In One positive exp #50706

I was at a banging party and I bumped into an old friend who decided he wanted to try and stitch me up on some random drugs. At first I refused, but as the sun rose, the craving for acid hit me.

Not A Great One neutral exp #39180

Had 50 mg of 3CP. Have never done this before, or know anyone that has, not even the individual who gave it to me knew of anyone trying it. However I was told it was active in the 50 mg range. I was very cautious, and didn't want to do the full 50 mg, in case it was too much (other rc's it would be too much).

3c P 60mg First Time Subtlety At Its Finest positive

Wow. Well here it goes then. Me, and my two new neighbors in my new dorm building all were included in this trip. I took 60mg, and they took 45 each, but I hadn't eaten for over a day (I'd just been asleep a lot...I'm not anorexic, lol.) We all took it around 8:10, and I expected about an hour to an hour and a half of...
