Ok, sorry to be reviving an old topic but the info in here about 4-aco-dmt is not accurate.
I have tried almost every single psychedelic out there, you name it, I've tried it. I would guess almost a hundred trips over the course of about 10 years.
4-aco-dmt, although classified a research chemical (if you can classify 4-aco-dmt as a research chemical, technically, so can LSD.), it feels extremely transparent to the body, in much the same way nn-dmt feels.
It is a cross between shrooms and DMT, leaning more towards DMT in visuals and smoothness, but the duration and onset similar to shrooms.
I cannot praise 4-aco-dmt enough, it feels so natural, so right every single time, I cannot put my finger on it.
At certain doses (betweeen 35-40mg for me), it feels like a strong ayahuasca trip, without the nausea and body load, coupled with the clearest headspace you can imagine.
At about 25mg, you are in the state of smoked DMT afterglow, that lasts for 5 to 6 hours.
I never feel 'worn out' like I ALWAYS do after a strong LSD, mescaline or mushroom trip, the comedown seems to ease me back very gently, and falling asleep afterwards is a breeze.
One message I keep getting from my trips on 4-aco, is this is the key to unlocking the next change in consciousness for the coming of a new age.
I'm not sure how yet..
