4-AcO-MiPT, or 4-Acetoxy-N-isopropyl-N-methyltryptamine, is a synthetic indole alkaloid molecule of the [[tryptamine]] class.

4-Acetoxy-N-methyl-N-isopropyltryptamine (abbreviated 4-AcO-MiPT and also known as mipracetin) is a synthetic psychedelictryptamine. It is the acetylated form of 4-HO-MiPT (also known as miprocin) and is a higher homolog of 4-AcO-DMT, 4-AcO-MET and 4-AcO-DET. These substances are commonly hypothesized to act primarily as prodrugs for their respective hydroxylated counterparts (e.g. 4-HO-DMT, 4-HO-MET and 4-HO-DET), although there is on-going debate as to whether they possess their own innate activity.[citation needed]
There is very little information on the human pharmacology or toxicity of 4-AcO-MiPT, although analytical methods have been developed for its detection.[1][2] Today it is either used recreationally or as an entheogenic substance and is typically acquired through the use of online research chemical vendors. It remains relatively uncommon and has very little history of human usage.
4-AcO-MiPT, or 4-Acetoxy-N-isopropyl-N-methyltryptamine, is a synthetic indole alkaloid molecule of the tryptamine class. Tryptamines share a core structure comprised of a bicylic indole heterocycle attached at R3 to an amino group via an ethyl side chain. 4-AcO-MiPT is substituted at R4 of its indole heterocycle with an acetoxy (AcO) functional group CH3COO−. It also contains isopropyl and methyl chains bound to the terminal amine RN of its tryptamine backbone (MiPT).
4-AcO-MiPT is the N-substituted methisopropyl homologue of 4-HO-DMT (psilocin). 4-AcO-MiPT is the acetate ester analog of MiPT and the N-substituted methisopropyl analog of 4-AcO-DMT.[3]
Like with most psychedelic tryptamines, 4-AcO-MiPT is thought to act principally as a 5-HT2Apartial agonist. The psychedelic effects are believed to come from 4-AcO-MiPT's binding efficacy at the 5-HT2A receptors.
However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
Subjective effects
Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWikicontributors. As a result, they should be viewed with a healthy degree of skepticism.
It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.
Sedation - In terms of its effects on the physical energy levels of the tripper, 4-AcO-MiPT is considered by most to be relaxing, stoning and mildly sedating. This sense of sedation is often accompanied by uncontrollable yawning.
Spontaneous tactile sensations - The "body high" of 4-AcO-MiPT can be described as a pleasurable, warm, soft and all-encompassing tingling sensation. This maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached.
The visual geometry of this compound can be described as more similar in appearance to that of 4-AcO-DMT, ayahuasca and 2C-T-7 than LSD or 2C-B. It can be comprehensively described through its variations as intricate in complexity, abstract in form, organic in style, structured in organization, brightly lit and multicoloured in scheme, glossy in shading, soft in edges, large in size, slow in speed, smooth in motion, rounded in corners, non-immersive in depth and consistent in intensity. The visuals have a very "natural" feel to them and at higher dosages are significantly more likely to result in states of level 8B visual geometry over level 8A.
Hallucinatory states
4-AcO-MiPT and its various other forms can produce a full range of high level hallucinatory states in a fashion that is more consistent and reproducible than that of many other commonly used psychedelics. These effects generally include:
Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - This effect is very consistent in dark environments at appropriately high dosages. They can be comprehensively described through their variations as lucid in believability, interactive in style, new experiences in content, autonomous in controllability, geometry-based in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental nature in their overall theme.
Cognitive effects
Much like its counterpart 4-HO-MiPT, the cognitive effects of 4-AcO-MiPT are described by many as extremely relaxing, complex and stoning in style when compared to other commonly used psychedelics such as LSD or 2C-B which tend to be energetic and stimulating. It contains a notable number of typical and unique psychedelic cognitive effects.
The most prominent of these typical effects generally include:
Enhancement and suppression cycles - This can be described as constant waves of extremely stimulated and profound thinking which are spontaneously surpassed in a cyclic fashion by waves of general thought suppression and mental intoxication. These two states seem to switch between each other in a consistent loop once every 20 - 60 minutes.
Anecdotal reports indicate that users of 4-AcO-MiPT, as well as 4-HO-MiPT, may experience auditory distortions marked by a downward shift in perceived pitch, similar to those most commonly associated with DiPT. While not as prominent as in DiPT, user accounts suggest a likely shared origin for these distortions.
Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.
It should be noted that these effects are reported to occur less reliably and impactfully than with psilocybin or 4-AcO-DMT, and generally require heavier doses to induce.

Dangerous interactions
Warning:Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).
Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.
[[Wikipedia:Lithium_(medication)|DangerousInteraction::Lithium]] - Lithium is commonly prescribed for the treatment of bipolar disorder. There is a large body of anecdotal evidence that suggests taking it with psychedelics significantly increases the risk of psychosis and seizures. As a result, this combination is strictly discouraged.
"[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Cannabis may have an unexpectedly strong and unpredictable synergy with the effects of 4-AcO-MiPT. Caution is advised with this combination as it can significantly increase the risk of adverse psychological reactions like anxiety, paranoia, panic attacks, and psychosis. Users are advised to start off with only a fraction of their normal cannabis dose and take long breaks between hits to avoid unintentional overdose.
