While I'm aware that every chem is different, how would you say aMT compares to it's 5-meo counterpart?
5-MeO-AMT hits harder, lasts longer, and has a ton of side effects... Let me ask you this - did you enjoy 5-MeO-DMT or 5-MeO-DiPT? Because if you enjoyed one or both of those you are much more likely to enjoy 5-MeO-AMT. It has that very high bodyload of methoxylated tryptamines, those two specifically. Diarrhea, tachycardia, nausea, vomiting, the possibility of dysphoria, a steep dose/response curve, it borders between being physically stimulating and physically sedating which can make it into a very weird combination especially if you aren't very well-rested or towards the later hours, 12 or so in to the experience.
AMT reminds me more of a candyflip with very little visual input whereas 5-MeO-AMT is a technicolor wonderland. I go back and forth on whether the headspace of 5-MeO-AMT and AMT differ much because I have said that both of them have very little mindfuck but that simply isn't the case. They aren't as twisted as LSD but they both have a very distinct mental component. High doses of 5-MeO-AMT seem like the 5-MeO-DiPT psychosis without fully snapping the mind like 5-MeO-DiPT does. Its hard to explain. The body high from it is very rushy but not always clean rushes like AMT can cause, it feels like the alien rush you get from 5-MeO-DiPT and can be quite chilling when you're not used to it.
Both AMT and 5-MeO-AMT I tended to go to sleep at the same time, around the 18-20 hour mark, which basically puts them about equal in terms of overall stimulation for me, however, you're still tripping a little bit at that point with 5-MeO whereas AMT was gone a good 5 or 6 hours before that.
Obviously for me, the positive visual aspect was enough to outweigh everything else or I wouldn't have done it so much.
I must admit that it was rather odd going in the bathroom feeling sick to my stomach and not much else and then puking and/or shitting my brains out and leaving the bathroom with everything around me flowing, patterns drawn all over surfaces, and pupils the size of marbles 15 minutes later. I never puked twice but loose stools for the first few hours were a problem quite often. That said, it was rewarding because each time I'd use the bathroom, I would trip harder for awhile. It was a very consistent effect. Totally cathartic.
With all of that said, I would take AMT over 5-MeO-AMT these days but I'm also much more beaten down than I was back then. Daily benzos and such. I don't think my nervous system could handle 5-MeO-AMT anymore. Every single sense gets overloaded. Interestingly enough, I was able to hide that I was intoxicated most of the time unless my pupils were looked at. Conversations, while they gained more depth than usual, were generally very put together and smooth and I didn't have any problem doing my normal routine on it. I even went to work tripping on 5-MeO-AMT and went through my day completely fine. Just a glance in my direction would make it immediately apparent that my normally blue-green hazel eyes were almost pitch black however.
Toxicity-wise, I would compare it with 2C-T-7. Out of those two chemicals, they are both insanely visual and insanely hard on the body. I would say that 5-MeO-AMT was slightly worse just because of the duration and the diarrhea but 2C-T-7 caused me to projectile vomit and I blacked out from it as well at a 16mg dose so toxicity would be up for debate between the two in my opinion.
Also, 5-MeO-AMT maintains AMT's unpredictability that you mentioned Captain. They're both a lot like LSD that way.
One final thing that I will tell you re: AMT vs 5-MeO-AMT is that on 5-MeO-AMT, I felt safe enough to mix it with a 2nd plateau level of DXM, something that I never would have done on any dose of AMT. Its all relative. Perceived toxicity can be entirely different from actual toxicity. I have no idea what damage, if any, my abuse of 5-MeO-AMT caused or will cause but I can say that for every drug. I hadn't used either of them for a few years and was just rolling and that is what trashed me to the point that I had to be on meds all these years so you tell me.
TotalTotalness - LSD overpowers AMT and AMT triggers a minor cross-tolerance so you would need more acid. Its best to just save the AMT or LSD for another time than to mix them together.
