4‑AcO‑DMT: My First Run Through and Dose Query

Posted by aspiring_trailrun in General Discussion - 6 points, 8 comments.

I took 4‑AcO‑DMT last week for a solo trip in the cottage by the river. I started with 2.5 mg, the lowest dose people usually mention, and ended up feeling the typical psilocybin‑like swirl of colour and sound. A few minutes in, my heart rate went up by about 20 beats per minute, which I noted on my smartwatch. There was a brief moment of unease, but I stayed in a dark room with my headphones on and diseño calm music, so it resolved quickly. I kept going for another hour, then sat in the garden for a 20‑minute grounding session. When thecrime ended, I felt oddly refreshed and more in tune with my breathing.

I’m curious how others are dosing and timing. I used a 2.5‑mg start because the lab notes say that’s a low dose, but some of you hit the full 4‑mg range. How long do you wait between doses if you do multiple sessions? Also, any tips for managing that initial jitteriness if you’re new to 4‑AcO‑DMT? Any feedback would be appreciated.

  • greg208: I’ve never tried 4‑AcO‑DMT yet, but the other people who’ve used it say 2–3 mg is a safe start for a normal‑sized adult. I’ve used a 3‑mg dose of DMT‑in‑oil and found that waiting at least 6–8 hours before a second session is a good rule of thumb, because the brain can still be re‑sensitised. With the first hit, the heart‑rate rise you saw is normal – I felt a similar bump after a 10‑mg psilocybin trip, so nothing to worry about if it stays under 40 bpm. To tame the jitter, I keep a low‑key env
  • aspiring_trailrun: Thanks for the pointers. I’ll try a 6‑8 hour gap before another 2.5‑mg session. I found the 20‑bpm rise harmless, but I’ll keep an eye on it. You mentioned a short breathing or grounding walk – could you share the routine you use? Also, any advice on pre‑dose hydration timing?
  • greg208: Not gonna lie I’ve been around the 4‑AcO‑DMT trail for a handful of trips. 5 because the first tickle can feel a bit sharp for a bud‑newbie. I keep a close eye on my heart rate – a 15–20 bump is normal – and pair the dose with a calming playlist and some slow breathing. If you’re thinking a second hit, give it at least 90‑120 minutes; the body needs time to metabolise before another surge. I’ve found that grounding in a quiet spot after the peak really pulls you back to a steadier baseline.
  • aspiring_trailrun: Thanks for the pointers, greg. I noted the 20 bpm rise myself and will keep an eye on it. I’ll try the 90‑120 minute window before a second hit and then do a quiet grounding walk. Do you have a specific breathing pattern or playlist that really calmed the jitteriness for you?
  • grace_sleepnerd: Thanks for the tips, greg208. 2–3 mg as a low‑start makes sense, I went 2.5 mg and my watch jumped about 20 bpm, just like your 10‑mg psilocybin note. I haven’t tried a repeat yet, but I’ll follow the 6‑8‑hour rule. Do you have a go‑to breathing cue that works best before a dose?
  • aspiring_trailrun: I’ve been doing a simple 4‑second box breath, 4‑second inhale, 4‑second hold, 4‑second exhale, 4‑second hold, and repeating that until I feel calm. It kept the heart rate spike under 30 bpm for me. I’ll try that before my next dose and let you know how it goes. Good luck with the 6‑8‑hour window!
  • hank_sauna: I’d say you’re spot on, greg. I used 5 mg for my first solo run too and kept an eye on the watch – 15‑20 bpm uptick felt normal. I paired it with a chill playlist and a few deep breaths. After the peak i sat in the shade for 15‑20 minutes, which helped me come back steadier. 90‑120 min between hits is wise. Imo.
  • aspiring_trailrun: Thanks for the solid comparison. I’ll push my next session to 90 minutes after the first, just like you. The 15‑20 bpm rise I saw was a bit higher than yours, so maybe a longer cool‑down in shade helps. Do you find the garden backdrop more calmingExplore the difference between shade and sitting in a shaded garden? I’d love a tip on that. Also any breathing rhythm you used to bring the jitter under control?
