I don't know about LSZ (I'm going to order a few hits when I'm finished buying textbooks), but honestly AL-LAD is sort of better in my opinion. High doses can be indistinguishable, and if you really want solid ego loss, you can also boost it up with a hit of nitrous at the peak... or maybe a psilocin analogue if you really want to blast off. Also, you know it's a standard dose of exactly what you're expecting...not to mention it's perfectly legal (depending on where you are I guess). Peace of mind is something you can't put a price on. All these factors combined, I would say the price is well worth it. And the price isn't even too bad. If you buy enough it works out to around the same as, or cheaper than, LSD, at least for me.
I've tried LSZ and LSH and I did not like them very much. Much rather stick to LSD, But AL-LAD sounds much more promising. Woot 1000 posts!
I just did 450 AL-LAD this afternoon out in the autumn woods. It was utterly mindblowing. There were times where I would just have to sit down in a clearing and I would literally melt into the beautifully coloured trees around me. Maybe set, and setting, more probably tolerance, as I had 4-AcO-DMT the day before, but a 600ug dose another time just wasn't as magical. As far as intensity that's dipping my toes in the water as far as I'm concerned. I'm hoping to get to that same place, but once there, IM some DPT or 4-AcO-DMT and really break through, sitting right there in the October forest next to a nice gurgling creek.
I'm eager to explore this chem. I was going to do a faux candyflip with 6-apb and a 150 ugs hit of AL-LAD last night but refrained due to not feeling the set/setting. So hopefully I find some time within the next few weeks to dose. Based on the info on this thread I'm likely going to jump in and go with 300 ugs.
