I have no experience of acid. I tried this stuff yesterday and it was mental. Music appreciation was through the roof. I couldn't get the visuals I got off of it if I had taken half a gram of 2cb at once. It was so vivid I could barely see for a good couple of hours. (Some examples would be neon colours switching on bricks rapidly, creeping vines on stuff, DNA spirals on the ceiling, morphing and undulating, stuff in the distance being really close, stuff really close being really far away etc. Plus ridiculous shit like you get when you take MDA) Around the 6 hour mark the physical ecstasy type feelings were getting really tiring and wouldn't quit, but kept getting stronger. Every time I thought I was normal I was coming out of another layer, then i'd sink back into the trippy headspace/world. Very very positive, you could say that it was almost a bad trip when I was overwhelmed, but I am not 100% a bad trip for more than 1 phase of said trip could ever happen on this stuff, unless you were in a really bad place emotionally. My face actually hurts from how much I was smiling.
The way i'd say it went for me was sort of like heavy heavy 2ci and 2cb mixed together for the first 1-3 hours, with a little dash of ecstasy, then ridiculous other worldly dose of 2ci and 2cb and a nice dose of speed (fiendy and frenetic but slightly different to actual speed) at 3-7 hours. Maybe even like being in a k hole visual wise but being more present and able to move (dunno if that makes sense). At 6-7 hours I was getting noddy lie back and trip hard thoughts along with the hallucinations and overwhelming rushes, I lost my ego for a while and it took quite some time to rebuild. I had a lot of interesting thoughts and reflections/realisations, most of which were obviously bs. Then around the 7 hour mark I started to come down and it was almost like valium sort of chilledness, very calm and born again. Refreshed but very tried. I went to bed at about 2 in the morning. I smoked a huge spliff and was still getting slight visuals as I went to sleep. Today I feel pretty fantastic. There were 4 of us doing it and we all loved it. Personally, I don't feel the need to do it again though. It was verging on too draining, almost like running a marathon.
Some negatives/things to look out for: Because it seemed somewhat speedy, and we did it on a sunny day, and the time epic time dilation, we drank a lot of water. Needing to piss, and having the urge to urinate was frequent. I also felt like I needed to crap but couldn't go, which was annoying. And most of us have been err pretty loose today. An underlying pukey feeling followed most of us throughout the whole trip, but this was a lot more bearable than mushies. Although I felt no physical tension, some people in the group 'thought' they had a bad back, and genuinely felt like they had a bad back, but today it's just fine. So fuck knows what that's about. So, yeah. Just keep an eye on your water levels and stay safe. Leaving the house seems like a must, but if you do it in public make sure there aren't too many people around (obviously). Definitely keep some beer and weed around for the down phase if that's your thing, a valium to sleep on also wouldn't go a miss but isn't necessary.
All in all a tenner well spent (the vendor sent me 8 hits instead of 10, what a jip). Get in there before the government realises there's fun to be had legally. I can't really believe that experience was had off of what was supposedly 150 micrograms, I can't comprehend what people must be getting off of twice or even three times that amount.
