18mg 4-ACO-DMT, fumarate salt, dissolved in 2ml of water, injected intravenously was astoundingly powerful. I thought I'd be up to the task -- I really wasn't. I watched the postive vibes collapse and wither all around me and the negative ones took over. I had to abort with 6mg etizolam, and shortly after that, maybe an hour later--I passed out for 5 hours. I should have waited until setting and mindset were in a better place. Also, I won't be playing with this stuff IV again for a bit. lol Very potent.
In fact, it wasn't but a few seconds after injection that I started seeing the fastest mandelbrot animation before my eyes, almost opaque, so I couldn't see much beyond it -- it overwhelmed me and I didn't know how to enjoy it. I moved from room to room, actually in a bit of a panic. Standing up, pacing, laying down, getting back up. I have never experienced closed-eye visuals like that before. I thought I'd really fucked myself, and I'm no noob to psychedelics. This is so much more potent, IV at least, than any lysergamide or tryptamine I've tried, even at 18mg. I think I needed that, just to remind me I'm playing with fire.
I was humbled.
