    Summary dose.wiki TripSit PsychonautWiki

    4-HO-DET is a research chemical with very little history of human usage. The toxicity and long-term health effects have not been studied in any scientific context. Compared to psilocin, 4-HO-DET has been reported to have a slightly longer duration, less pronounced bodily effects, and more synthetic or algorithmic-style visuals.

    Perspectives

    “This is perhaps one of the more boring psychedelics I have tasted. The experience does not lend itself to any meaningful thought processes or profound explorations of existence.”

    “This was in a gelatin capsule and it came on from a half hour to the three-quarter hour point like gang-busters. Time really slowed down, with sparkly-ness, interesting, and yet there was a touch of sadness. The intense visuals held the scene, and there was the compulsion to talk and to interact and to share stuff, but the erotic was not to be found. I slept OK but there was something uncomfortable at a deep level. Am OK.”

    Effects Erowid

    Aggregated from 11 single-substance Erowid experience reports; 7 Erowid reports where another drug was taken too are left out

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

    Too few reports for bars: these effects come from 11 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

    The shit is fucking crazy. I would put the general ambient vibe of the drug as an odd and unsettling cross between mushrooms and LSD. Definitely good shit, and I took a lot of it. Zero Hour. I and my friend R are fucking around in some music store in my hometown.

    Intro: Had planned my day out earlier in the week, very clean house, organized spaces, intentions set and a ready mind. Not trying to 'control' things too much but preparing. A perfect day outside in the wild west here, 70 degrees, sunny and mild wind. 9:50am I took 35mg (between 35mg and 40mg, scale problems).

    Ethocin for some reason always interested me, and a year ago when I passed up the chance to acquire some, I was very saddened. Recently, though, I was able to get my hands on a gram for experimentation. This particular venture was between my significant other of several years, and myself in our home.

    I consider myself to be a highly experienced psychonaut, I've had hundreds of experiences with 2C-I, 2C-E, 5-MeO-AMT, 5-MeO-MiPT, 5-MeO-DMT, DOC, 4-AcO-DMT, 4-AcO-MiPT, mushrooms, ayahuasca, LSA, amanita mushrooms, yopo, and I was looking forward to this new tool to add to the bag.

    This is perhaps one of the more boring psychedelics I have tasted. The experience does not lend itself to any meaningful thought processes or profound explorations of existence, rather it is a dull neutrality that I simply drifted through, gaining nothing.โ€ฆ

    Tryptamines The Big & Dandy 4-HO-DET Thread

    4-ho-DET has produced some decent experiences. I could have gotten the same experience, with a more chemical feel from MDA. I'd compare it more to MDA than mushrooms... but not as rushy by far.
