Prior to this experience, my typical club dose was about 60-70 mg, with a max of about 80 mg in a club. I've done this numerous times and am able to handle it quite well by now, so I figured I'd probably be able to handle an even bigger dose. I had not used any psychedelics for several weeks before this experience, so tolerance was not a factor.
I used 2C-B powder from a reputable dark net vendor that I've personally gotten lab tested. I measured doses with a milligram scale and put it into capsules.
T+0:00 55 mg orally before leaving for the club. I brought an extra 55 mg capsule with me.
T+1:00 At the club, starting to feel the effects. Onset is slower than usual since I had consumed a lot of food earlier in the evening.
T+1:30 The music sounds great. I'm a big fan of techno, and this was some exceptionally good techno (even when I felt sober just after arriving). I'm dancing a lot and feeling really good, so naturally I decide to take the other capsule (what could go wrong). My vision is already full of geometric patterns, and all the light effects in the club look really, really good.
T+2:45 I'm now at the peak. Vision is almost completely covered by all kinds of visuals, so seeing is a bit of a challenge. I'm still dancing to the music, and it feels like the DJ is channeling some kind of magical musical energy to the entire crowd, and everything just feels right. I felt like I had become the music - I was completely entranced.
T+3:00 I'm in the middle of the dance floor, and I realize that I'm in the middle of an ego death. My ego no longer exists, all that exists is the music, and I feel like all I can do is keep dancing. It's a bliss-like experience, all is good in the world.
Around this time I go and get some water, and I'm surprised that I'm still able to communicate with a guy I met by the bar. We exchange a few words and I go back to dancing until the music stops.
T+4:00 The night is over, I walk home. I'm past the peak, but I've never seen such pretty street lights as what I saw on that walk, greatly enhanced and animated. Car lights were very pretty since they're so bright. I was even able to think clearly enough to not step into traffic and get myself killed.
I slept for about 10 hours, and the next day I had a headache for most of the day (nothing debilitating), otherwise I felt just fine. The next day I felt 100% normal.
During the peak I experienced some gurning (significantly less than with MDMA), which I've never had from 2C-B before.
