The 4-AcOs and 4-HO's are the most benign out of any of the RCs for me.
5-MeO-MiPT is next
Then AMT
Then Foxy.
Out of all of them, AMT and 4-HO-MiPT are currently my favorites. Hard to say which substance I'd go with if they were both put in front of me... but right now, I'm leaning towards AMT.
AMT definitely has a bodyload. It can make you extremely nauseous to the point of vomitting but once that has passed, its usually smooth sailing until the comedown. I don't get much physical stimulation from it but the comeup feels like speed without the physical. Generally about 1-2 hours after the comeup is over, the speedy feeling goes away and the trip hits. Then I don't notice anything negative until I come down. Then its time for some ibuprofen to get rid of the mild headache and moderate bodyaches.
5-MeO-MiPT I've only done once... but it was extremely benign, even at the dose I did, which was 18mg or so IIRC. The body high was really pleasant, there was no nausea or anything to speak of... but there was still a slight feeling like I was poisoned throughout the trip, kind of like what one feels when coming up on shrooms.
5-MeO-DIPT... fuck that shit. Nuff said.
Now on to 4-HO-MiPT. I prefer 4-HO-MiPT to shrooms, 4-HO-DiPT, 4-AcO-DET, 4-HO-DET, and 4-AcO-MiPT. It hits faster and harder than any of them in my experience and its also got a longer duration than all but the AcO-MiPT.
The body high is reminiscent of shrooms and can be quite euphoric.
The only physical negative with it is I definitely noticed some fluid retention going on so watch your salt intake the day that you decide to do it.
Now, those were the ones you had on the list.
Me personally, I find AMT, 4-HO-MiPT, and 2C-E to be the most fun, with 5-MeO-AMT and 2C-I being the two least fun.
