Hi Soli
I find them to be somewhat reminiscent, but still different. In my experience 2C-E is highly analytical, but very intellectually centered. And it's reported "neutral" character makes it feel a little bit cold sometimes ... Although that's relative because I've been pretty euphoric for moments on 2C-E. 2C-P Is also analytical, but in a way that I find more "emotionally centered". At least for me, it feels almost empathogenic because it is very introspective and emotionally cleansing. I find it a little bit warmer than 2C-E, and a little bit more clearheaded, Though at 10 mg it started to get a lot more confusing and ridiculously visual so I decided that was my personal limit and haven't pushed it further. At 8 mg I always get a nice therapeutic effect, and the relative clearheadedness makes for more productive introspection.
The duration isn't much of an issue, in my opinion. It takes around an hour and a half to start coming up, and when it does it is very slow, which I find enjoyable because you can feel how you melt into psychedelia step by step. At the third hour I start peaking, and the peak lasts for about eight hour. By the twelve hour there´s only some faint sensory psychedelia but headspace is mostly clear, and the lingering stimulation can last a two or four hours after the peak ends.
So all in all, it lasts about 14/16 hours, but discounting the onset, you'll only be tripping for 12/14 hours, which isn't that much different to LSD which can last for about 10/12 hours easily. Not a short trip for sure, but I don't find it THAT taxing.
It can get dark sometimes, though. It is as stimulating as 2C-E, which I personally find very stimulating, an that extra energy has made me anxious sometimes, but not an issue if you are an experienced user - and I suspect you are
. It makes you hyper-aware of sounds, in the same way that 2C-E does (for me at least), and that can make you anxious if you are tripping at night in the quiet, or in nature, or something. My first times with it I got moments of "THE FEAR", but nowadays I don't really get it. Not a beginner psychedelic in a way, but then again it was the third psychedelic I ever had and my fourth trip ever, and at a low dose I had a good time.
I think it is my favorite psychedelic, but it seems it just agrees with me specially good because I never see this one getting that much love. Every time I have taken it it has been incredibly healing and insightful. But I think part of it is that, because it is still a long trip, I've never taken it casually, and every time I've made sort of a "ritual" out of it, taking it with clear intentions, so set and setting as always.
