My thoughts on AMT:
There are four stages to the experience: 1) Starting 30-45 minutes after ingestion, a shitty speedy 1-2 hour come-up that is the worst of any psychedelic I've tried 2) A very empathogenic, MDMA-like state with a unique tryptamine signature of authority (i.e. I don't feel e-tarded) which flows pretty gradually into the next phase 3) A LSD-like psychedelic state, and then 4) A comedown phase very similar to that of LSD but slightly speedier.
The plateau (stages 2-3) is LONG (at least 8 hours), and the peak comes about 5-6 hours into the experience (right in the middle of the transition from MDMA-like to LSD-like).
The visuals are very much like those I get on acid, but they are friendlier and more controllable. I definitely do notice the "nystagmus effect" of not being able to focus on things properly at higher doses. The visuals tend to start weak and get stronger and stronger as the trip moves on and becomes more LSD-like. With higher dosage, the visuals become stronger much earlier. When I took 80 mg of freebase (which is equal to 100 mg of hydrochloride salt), I started to get CRAZY ASS VISUALS in less than an hour (which coincided with some of the shitty speedy come-up effects, and the only time I've ever puked on a psychedelic other than ayahuasca). They were very acid-like, but with more "wavyness." Somebody mentioned sideways distortion akin to a badly tuned TV, which is a good analogy. I had very strong OEV's for the entirety of the 8 hour plateau. CEV's were incredibly intense. When I closed my eyes I was tunneling through multi-dimensional information networks at an incredibly high speed.
As for introspective quantities, I believe AMT definitely has psychotheraputic/shamanistic potential. It lacks the abrasive hyperanalytical edge of LSD, intsead catalyzing empathogenic introspection similar to that of 2C-I, 2C-B, or MDMA. Nonetheless, despite these qualities, and the fact that it is the indole analog of amphetamine, its overall character is definitely that of a tryptamine. The visuals, euphoria, insights, and even the empathogenic effects carry a distinct tryptamine signature. MGS, I would not be concerned that you will not get anything out of this substance. If your intent is proper, you will be able to use AMT for spiritual exploration. I definitely think that the unique, positive effects of this compound are worth the speedy side effects.
