    Summary TheDrug.Wiki Erowid TripSit PsychonautWiki

    5-MeO-DMT is an extremely potent, fast-acting psychedelic tryptamine known for producing intense mystical experiences with minimal visual effects. Unlike N,N-DMT, 5-MeO-DMT is approximately 4-20 times more potent and carries greater safety concerns, including several documented fatalities. It preferentially activates 5-HT1A receptors over 5-HT2A receptors, making it an atypical psychedelic.

    Perspectives

    “I felt it in a minuteβ€”not really light head, but the head feels close to the lower parts of the bodyβ€”close to the groundβ€”knees weakβ€”distinct shakes. I peaked at 2 or three minutes. It was quite intense, but not the max of DMT at 30 milligrams and no sensory close-out. Slight nausea on the drop-offβ€”I am glad I had not eaten anything. Overall comparison to DMT, more potent, slightly faster, but like DMT is largely a simple, stoning drug with no sensory contribution, no intellectual contribution. It’s greatest contribution might be to provide a subject the vocabulary of an altered state of consciousness so that, with interesting and constructive drugs, these effects will be familiar, and thus not distractions.”

    Users frequently report marked acute tolerance if re-dosed within the same session; effects are often blunted or dysphoric. Cross‑tolerance with other serotonergic psychedelics is plausible via 5‑HT2A down‑regulation, but quantitative data are limited; estimates here are conservative and anecdotal.

    Had the deepest trip of my life last night. positive r/5MeODMT ▲149 41 comments

    I had the deepest trip of my life of tripping last night on the 5. Took a breakthrough dose hit and was immediately knocked down to my back as it had taken over. I lay there as it dismantled and disintegrated my ego within seconds as I wake up to Reality.

    Many years ago I used bufo venom. First time was 90mg vaporized. Didn’t quite get the whole hit. Everything sizzled in my vision and then it took me. It was beautiful, amazing, and powerful. It was warm and psychedelic and expansive and so many things that go beyond words.

    About 25 years ago, my small group of friends learned about 5MEO and bought some online. Mind you, this was probably when most of you were either in grade school or not yet born. I’m 45 now, 5 kids, married. Etc. I only did it once. 15mg dose of pure lab synthetic from Germany.

    As I pause to reflect on what I experienced nearly 30 hours ago, the most profound moments of my life, I am filled with utter disbelief. My first true experience with 5-meo-dmt was nothing short of amazing, although such a word is painfully lacking.

    This was my first experience with any form of DMT. I did very little research prior to embarking on this journey to inner space, therefore I had little idea what to expect. IΒ’ve had numerous psychedelic experiences in the past 40 years, but none in the last 10. None have prepared me for what 5MeODMT had to offer.

    I have had several attempts before this to breakthrough on 5-MeO-DMT. I now believe that I was approaching the experience in an entirely ineffective way. Set and setting is extremely important with any psychedelic, but it is absolutely necessary to prepare correctly for a drug with this power.

    An insight into my first experience with the entheogen 5-methoxy-dimethyltryptamine (most commonly known as 5-MeO-DMT), a powerful tryptamine. Objective analysis of the experience is complicated since the effects are volatile, and minimal dosage changes can induce violent differences.

    My journey with toad medicine was without question the most intense and impactful psychedelic experience I've ever had. LetΒ’s start with a bit of context. I was aware of the toad for years, but I never pursued it.

    It is commonly accepted that there are three distinct stages of the transformative experience (trip): The first stage being the Preparation, the second stage, the Experience itself, and the third stage the Reflection, or Processing of the experience.

    Intravenous 5-MeO-DMT - The Drop Rejoining the Ocean I had spent a great deal of time studying other people's experiences with 5-MeO-DMT, finding reports which told stories of incredible bliss and others which told of literal near-death including cessation of breathing and loss of consciousness.

    [Includes Updates written eleven months and fifteen months after the original report (two years after the experience). ] I do not encourage others to try this or any other psychoactive substance. I have had a very positive view of psychedelics as a medicine/teacher.
