I tried ETH-LAD this weekend, on Saturday, I had 2 150ug tabs, and given that with all other lysergamides I have tried, I seem to have a natural tolerance, I took both, and went river hiking (climbing boulders/balancing/jumping up a mountain river). I will write a full report when I get to it, but hot damn if that wasn't about the most visual thing I've ever taken. About an hour in, everything started to brighten substantially and pulse at me. Hard to describe, but the sky and trees and water looked just so bright and vibrant, and they seemed to throb in towards me. Another half hour and my entire visual field was overtaken by patterns and morphing, so much so that it was entirely distracting and difficult to tell what I was doing unless I focused. My friend's face was constantly morphing from old and withered to young, and his mouth seemed to be made up of many mouths, all moving at once. The rocks and lichens on the rocks were moving wildly. At times I would have to pause and focus so I could tell where I was about to actually put my hands or feet. Watching a waterfall, it was impossible to tell where the water began and ended. My coordination was unaffected and I did not feel nervous at the physically dangerous activity I was engaged in. At the midpoint, at the base of a large waterfall which we later climbed, my friend and I sat down and had deep and meaningful discussions for an hour or so. He was on DOC, and did most of the talking. I did feel like my speech was a bit impaired, it was sometimes hard to get out what I was trying to say, but I felt very with it. The entire trip had a serene feel that was not totally dissimilar to mescaline. I wasn't exactly euphoric, but I felt really good and peaceful. I would find myself going off on psychedelic mental tangents one minute and then I'd feel mostly sober (minus the overwhelming level of visuals) the next.
Overall I found I like ETH-LAD more than AL-LAD, although AL-LAD was more outright euphoric for me. I found ETH-LAD substantially more visual than either LSD or AL-LAD, and the visuals were very powerful and classically psychedelic. It seems like with ETH-LAD, I don't have an unusual natural tolerance. 300ug was easily manageable but very strong. Contrast that with LSD where 300ug leaves me wanting more, and with AL-LAD, where it doesn't even get interesting until 450ug.
