4-Aco-DMT was indistinguishable from a shroom trip for me. Still an amazing fun time though. 20-25mgs is what I would do when I took it.
~250ug of AL-LAD spread out over a couple of hours was a very fun low-intensity trip that lasted 5-6 hours and then died off completely. Felt similar to maybe 2 grams of mushrooms.
However 300ug of AL-LAD taken all together at once, is up there with some of my favorite psychedelic experiences so far. Very intense visuals and distortions. So much so that if I picked up a can of soda, and the can was red, everything in my entire field of vision would get painted with waves of red for about 2-3 minutes. Anxiety was minimal, although obviously you get a tingly energetic body high. It was a bit more "inward" than LSD was, but not any less mental. Out of all the classical-esque psychedelics I have done I would say AL-LAD was the least paranoia or fear inducing. It was very similar a television or hollywood depiction of an acid trip. No downside to it really, I plan on my next trip being another ~300ug AL-LAD experience. Thumbs up from me. Sleep was hard to achieve 7 hours after dosing, but was able to get some shut eye after the 8 hour mark.
Keep in mind I was also smoking weed throughout all of these experiences which definitely brings shit up a notch.
I don't know I can make a choice for you, but personally AL-LAD was top notch. Although both were great psychedelic experiences and would be suitable for a first trip. Also, dosing from a blotter is much easier than weighing out miligrams in my opinion. I would just make sure you get it from a good source, it's new compared to 4-Aco-DMT and I know that after the first synth there wasn't any going around for a while.... didn't it get scheduled in a few places too?
