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.

Summary
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.”

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
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
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.

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.
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...
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.
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.
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).

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...
