Just to add my 2p: A few weeks back I insufflated around 25mg. It's a weird one for sure. There wasn't much going on until T+0,5h, after that a transition to a very peculiar headspace took place which didn't lead up to a discernible peak but definitely was fully developed before T+1,5h. I kept asking myself if calling the compound a drug wasn't essentially misleading. What I experienced wasn't some form of intoxication, rather the opposite. There was some background tension and uneasiness I hoped to diffuse by visiting a nearby public pool and swim a few lengths. No visuals, no body high, no detectable distortion of any other of my senses, very very clear headed, none of that. So what did it do then, you might ask. My perception was cranked up quite a bit for once. I couldn't help but noticing a torrent of minute details I wouldn't usually be aware of, and was completely lost in thought about the architecture history of the little town I'm living in. No intensified colors, but childish joy when looking at brightly colored surfaces, especially yellow and orange. Once I was in the pool I kept drilling through a lot of issues and problems I needed to resolve, things I had to organize. My reasoning was almost too sharp and fluid like a razor, pitilessly weighing my actions and work and those of others with an almost brutal clarity. All the while I kept ploughing through the water without any hint of fatigue or exhaustion like the energizer bunny on steroids. This went on for 5km straight. Best description would be a state of clairvoyant super-sobriety, useful and interesting but not exactly enjoyable let alone hilarious. I felt my energy level draining and the tension from the rising muscle acidity, but wasn't compelled to slow down or tempted to give up. The drug didn't deceive me about what was left of my dwindling resources, but I felt that I'd be able to keep this up until total cramping or heart failure would force me too -provided the 4-aco-dpt wouldn't abate before that point. Let's hope the olympic committee has put this one one the list of doping agents, because I can see this one doing not a half bad job. My appetite was a little suppressed but not completely killed, I ate but there was no joy in it. The whole thing was over within 6 hours. Puzzling, but interesting enough to do it again sometime in the future, especially since the taste/smell was bearable and mild, no hint of the horrible dpt drip.
