I like 250 ug ald-52 + 200 ug eth-lad + 30 mg 3-ho-pcp/3-meo-pcp/3-meo-pce + 30 mg o-pce or just 60 mg 3-ho-pcp or o-pce... at that dose I can still function in reality (wouldn't say that I'm sober, but I'm there's no really weird shit going on).
At 500 ug ald-52 + 400 ug eth-lad + the same or slightly higher disso dosses things get insane. I've existed in multiple disjoint timelines at the same time (aka existed in timelines which couldn't happen at the same time, like in one I turned on the tv and watched a show, in another I didn't turn on the tv but went online, in another I petted my cat, ..... I'm not really sure what the actual sequence of events was but it felt like it was all happening at the same time subjectively..... it's really awesome if you are prepared for it but I can imagine it would scare many people), experienced infinity, talked to a being that called itself god (but told him that this is my trip and the only god here is me, reversed time, .holed and created a universe and two species that went to war for control of said universe, the war devastated and ultimately destroyed the universe, opened portals to other realities, .... Aka really weird and awesome stuff.
Anything higher is probably a waste since you wont remember most of the trip.
It also combines nicely with al-lad and or 4-aco-met/4-aco-dmt (and the dissos, imo they are an essential part of any trip since they make everything more believable and realistic, act as anxiolytics, either lower or make you not care about body load....
