5-MeO-MiPT, also known as 5-methoxy-N-methyl-N-isopropyltryptamine or by its nickname Moxy, is an atypical psychedelic drug of the tryptamine and 5-methoxytryptamine families. [1] [4] [3] It has unique and unusual effects compared to other psychedelic tryptamines. [1] [4] [7] [3] [6] At low doses, its effects include stimulation, tactile and sexual enhancement, some MDMA-like entactogenic effects, and introspective and mild perceptual changes with few or no psychedelic visuals or time dilation, whereas at higher doses, it produces 5-MeO-DMT-like classical psychedelic effects. [1] [4] [7] It is usually taken orally or smoked. [1]
The drug acts as a non-selective serotonin receptor agonist, including of the serotonin 5-HT1A, 5-HT2A, and 5-HT2C receptors, among others. [8] [9] [10] It is closely related in chemical structure and effects to 5-MeO-DiPT, and is also related to other tryptamines like 5-MeO-DMT, 4-HO-MiPT, and MiPT. [1] [4] [7]
5-MeO-MiPT was first described in the literature by Alexander Shulgin and David Repke and colleagues in 1985. [4] [6] [11] It was later described by Shulgin in greater detail in his 1997 book TiHKAL (Tryptamines I Have Known and Loved). [1] Recreational use of 5-MeO-MiPT is significant but relatively rare. [6] It is often used as a substitute for 5-MeO-DiPT, which has similar effects but was became a controlled substance in the United States in 2003. [6] The Drug Enforcement Administration (DEA) proposed banning 5-MeO-MiPT as well in the 2020s, but later withdrew its proposal amid public opposition. [4] 5-MeO-MiPT, under the developmental code name MSD-001, is being developed for the treatment of psychiatric disorders by Mindstate Design Labs and is in phase 1 clinical trials for this purpose as of 2025. [3] [12] [13] [14] [15]
In his book TiHKAL (Tryptamines I Have Known and Loved), Alexander Shulgin lists the dose of 5-MeO-MiPT as 4 to 6 mg orally and 12 to 20 mg smoked. [1] [6] A wider recreational dose range of 0.5 to 20 mg or more orally has also been reported however. [4] [16] [5] Oral doses of 1 to 3 mg have been described as light, 3 to 8 mg as common or moderate, and 8 to 12 mg as strong. [5] Its onset of action when taken orally is described as very rapid, occurring within 15 to 45 minutes, peak effects appear to occur after around 1 to 2 hours, and its duration as 4 to 6 hours. [1] [6] However, other sources state its duration as 3 to 8 hours. [4] [5] A clinical trial confirmed that 5-MeO-MiPT has an onset of about 30 minutes and that peak effects occur after about 1.5 to 2 hours. [3] Its duration smoked is said to be 2 to 5 hours. [6]
5-MeO-MiPT has been described as having unique and unusual effects relative to other psychedelic tryptamines. [1] [4] [7] The effects of 5-MeO-MiPT differ depending on whether it is taken orally or smoked and are highly dose-dependent. [1] [4] When taken orally at relatively low doses like 4 to 6 mg, it is usually described as not producing psychedelic visuals or related sensory effects and as producing only hints of time dilation. [1] [4] However, it is said to produce a stoned state that includes an ease of interpretive fantasy, dream-like perception, intense conceptual thought and philosophical thinking, and mild perceptual effects like altered depth perception, minor wave pattern in peripheral vision, and slightly enhanced auditory acuity. [1] Moreover, the drug is described as producing stimulation, greatly enhanced tactile sensation and eroticism, enhanced music appreciation, tingling, shakes, and mild motor impairment. [1] [4] Its head space is described as relatively "shallow", less confusing, and more easily tolerated compared to classical psychedelics. [4] Its effects have been described by users variably as both pleasant and negative. [1] [4]
When smoked, 5-MeO-MiPT is described as having effects similar in many regards to those of 5-MeO-DMT. [1] These effects of smoked 5-MeO-MiPT include a powerful rush (but less intense than 5-MeO-DMT), loss of coherent thought, not much in the way of visuals, closed-eye visuals of moving and colored geometric patterns, intense waves of mental imagery of emotionally infused memories, impressive recall of early memories, intense depersonalization or disorientation of the normal sense of being a person in a body, loss of immediate contact with surroundings, emotional lability including laughing, crying, and vocal outbursts, groaning, writhing, shaking around, and general disorientation. [1] It is described as having a very rapid onset, with the peak phase lasting less than 30 minutes and waves continuing for up to a few hours. [1] It was described by one user as feeling like a hybrid between diethyltryptamine (DET) and 5-MeO-DMT. [1]
5-MeO-MiPT is also known by its nickname "Moxy" [4] and is closely related both in terms of chemical structure and effects to 5-MeO-DiPT (also known as "Foxy Methoxy"). [1] [7] These two serotonergic tryptamines at low doses have been described as very aphrodisiac and much more stimulant-like and party drugs than classical psychedelics. [7] However, they have been described as not innately aphrodisiac, but instead as enhancing tactile sensation in a way that lends itself to sex. [7] Matthew Baggott has described 5-MeO-MiPT as having some MDMA-like entactogenic effects at low doses, including tactile enhancement and feelings of empathy, intimacy, and closeness with others, and as producing classical psychedelic effects at higher doses. [17]
Mindstate Design Labs has described 5-MeO-MiPT as the "least psychedelic psychedelic that's psychoactive". [3] It is described as being quite psychoactive, but as lacking "hallucinations" and as not producing "mind-bending trips". [3] The drug was assessed at five different doses by oral administration in a phase 1 clinical trial in 47 individuals. [3] Its effects included heightened emotions, associative thinking, enhanced imagination, and perceptual effects such as brighter colors. [3] However, there were no hallucinations, self-disintegration, oceanic boundlessness, or other typical features of psychedelic experiences. [3] Its onset was 30 minutes and its peak of effects was 1.5 to 2 hours. [3] Mindstate Design Labs has hypothesized that a mild psychedelic experience, as with 5-MeO-MiPT, could still provide therapeutic benefits without overt hallucinogenic effects. [3]
In addition to its use on its own, 5-MeO-MiPT, along with the related tryptamine psychedelic 4-HO-MET, is employed as a component of the MDMA-mimicking Borax combo. [4] [18] [19] [20]
Adverse effects of 5-MeO-MiPT include loss of appetite and insomnia. [1] Low-dose 5-MeO-MiPT did not cause any serious histopathological effects on the liver, kidney, and brain. High doses induce apoptotic cell death through caspase activity especially in some parts of the organs. [21] There is no known documentation of death attributed to the use of 5-MeO-MiPT alone. [4]

The mechanism that produces the hallucinogenic and entheogenic effects of 5-MeO-MiPT is thought to result primarily from serotonin 5-HT2A receptor agonism, although additional mechanisms of action such as inhibition of monoamine oxidase (MAO) might also be involved. [11] [22] In addition to the serotonin 5-HT2A receptor, 5-MeO-MiPT also potently binds to and/or activates other serotonin receptors, such as the serotonin 5-HT1A, 5-HT2B, and 5-HT2C receptors. [8] [25]
In addition to the serotonin receptors, 5-MeO-MiPT has also been found to show significant affinity to the serotonin transporter (SERT) and norepinephrine transporter (NET), thereby acting as a moderately potent serotonin–norepinephrine reuptake inhibitor (SNRI). [10] However, subsequent research contradicted the preceding findings and found that 5-MeO-MiPT did not significantly bind to or inhibit the human monoamine transporters. [8] [25] The drug is also inactive as a monoamine releasing agent. [22]
5-MeO-MiPT itself does not appear to have been studied, but the closely related drug 5-MeO-DiPT has been found to produce serotonergic neurotoxicity, genotoxicity, and associated cognitive deficits in rodents. [26] [27] [28] [29] [30]
Following intraperitoneal administration of 5-MeO-MiPT at doses of 2.7 mg/kg in mice the compound was detectable in blood, kidney, liver, and brain. [21] At lower doses of 0.27 mg/kg, concentrations of the parent compound remained below the limit of quantification in all samples. [21]
In one human case report 5-MeO-MiPT concentrations were measured at 160 ng/mL in blood and 3,380 ng/mL in urine samples collected approximately one and two hours post-exposure, respectively. [31]
In silico ADMET predictions projected high jejunal permeability and very high kidney permeability in MDCK cells, which suggests efficient gastrointestinal absorption and renal filtration. [32] The compound demonstrated nearly complete blood-brain barrier penetration (99% predicted), and was not predicted to be a substrate for P-glycoprotein, or organic anion transporters. [32] The predicted human percent unbound to blood plasma proteins was 45.5%, compared to 31.6% in mice. [32] The predicted volume of distribution (Vd) for 5-MeO-MiPT was 3.743 L/kg, lower than its structural analogue 5-MeO-DiPT (4.219 L/kg) and DMT (4.396 L/kg). [32]
5-MeO-MiPT undergoes extensive phase I hepatic metabolism, mediated by cytochrome P450 enzymes. In vitro experiments using pooled human liver microsomes identified seven phase I metabolites, of which five were found in vivo. [31] [33] The major metabolic pathways include O-demethylation, N-demethylation, hydroxylation, and N-oxide formation. [31] [33] The metabolic profile of 5-MeO-MiPT shows similarity to the structurally related compound 5-MeO-DiPT. [31]
In vivo analysis of forensic case sample identified five phase I metabolites in blood and seven in urine. The metabolites detected in both blood and urine included 5-MeO-NiPT, 5-HO-MiPT, 5-MeO-MiPT-N-oxide, and HO-5-MeO-MiPT. [31] Two additional phase II metabolites (glucuronides) were found in mice and in vitro models, but not in human urine sample. [31] [33] [34]
In silico ADMET predicted the compound to be a substrate but not an inhibitor for the CYP1A2 and CYP2C9 enzymes, and a substrate for CYP2A6 and CYP2B6. [32] Additionally, the compound is predicted to be both substrate and inhibitor for the CYP2D6. [32]
Detection of multiple metabolites in human urine sample two hours post-exposure, along with measurable blood concentrations at one hour, suggest relatively rapid metabolism and elimination. [31] Renal excretion is likely a major route of elimination. [31]
5-MeO-MiPT, also known as 5-methoxy-N-methyl-N-isopropyltryptamine, is in a class of compounds commonly known as tryptamines, and is the N-methyl-N-isopropyl homologue of 5-MeO-DMT. [1]
The chemical synthesis of 5-MeO-MiPT has been described. [1]
Analogues of 5-MeO-MiPT include methylisopropyltryptamine (MiPT), 4-HO-MiPT (miprocin), 4-AcO-MiPT (mipracetin), 5-MeO-DMT, 5-MeO-DiPT, 5-MeO-DALT, 5-MeO-MET, 5-MeO-MPT, 5-MeO-EiPT, 5-MeO-PiPT, and 5-MeO-iPALT (ASR-3001), among others. [1]
6-MeO-MiPT and 7-MeO-MiPT are positional isomers of 5-MeO-MiPT. [35] They have been described by Alexander Shulgin as being inactive at doses of up to 50 mg and 70 mg orally, respectively. [35] Another notable positional isomer is 4-MeO-MiPT. [1] [35]
5-MeO-MiPT causes the ehrlich reagent to turn purple then fade to faint blue. It causes the marquis reagent to go yellow through to black. [36]
5-MeO-MiPT was first described in the scientific literature by Alexander Shulgin and David Repke and colleagues in 1985. [4] [6] [11] It was later described by Shulgin in greater detail in his 1997 book TiHKAL (Tryptamines I Have Known and Loved). [1] The United States Drug Enforcement Administration (DEA) proposed banning 5-MeO-MiPT in the 2020s, but this proposal was later withdrawn. [4] The effort to make 5-MeO-MiPT a controlled substance was prominently opposed by the psychedelic community. [4]
The legal status of 5-MeO-MiPT differs internationally. It is not scheduled in Canada but is illegal if is sold for human consumption or recreational use , [37] and in Luxembourg it is not listed among prohibited substances, making it not illegal but a legal gray area there. [38] In the United States, it is unscheduled at the federal level, [39] but may be treated as an analog of 5-MeO-DiPT under the Federal Analog Act therefore if is sold for human consumption and not for medical or scientific uses is illegal and persecuted. At the state level, "5-Methoxy-N-methyl-N-isopropyltryptamine" is classified as a Schedule I controlled substance in Florida, prohibiting its purchase, consumption, sale, or possession. [40]
In other jurisdictions, control is stricter and could be punished by death or life imprisonment its sale for human use. As of September–October 2015, China lists 5-MeO-MiPT as a controlled substance. [41] Finland includes it in its decree banning certain psychoactive substances from the consumer market. [42] In the United Kingdom, it is classified as a Class A drug along with most ethers of ring-hydroxy tryptamines.[ citation needed ]
5-MeO-MiPT, under the developmental code name MSD-001, is being developed for the treatment of psychiatric disorders. [3] [12] [13] [14] [15] It is under development specifically by Mindstate Design Labs. [3] [12] [13] [14] [15] As of October 2025, the drug is in phase 1 clinical trials in the United States and European Union. [3] [12] [13] [43] [44] [45] A phase 1 trial was completed in July 2025. [3] [12] Mindstate Design Labs has developed an artificial intelligence (AI) platform known as Osmanthus to analyze trip reports in order to identify relationships between receptor interactions and psychoactive effects. [46] [47] [48] [49] Other research of this sort has also been conducted and published by other groups. [50] Mindstate Design Labs's platform has processed 70,000 online trip reports and led to the selection of 5-MeO-MiPT for development. [3] [46] [47] [48] [49] According to its developer, 5-MeO-MiPT is intended as a "neutral base compound" with mild effects on its own for use as a sort of "psychedelic tofu" in combination with other drugs to precisely modulate serotonin receptors and create various unique altered states of consciousness. [3] [46] [47] [48] [49]
5-Methoxy-N-methyl-N-isopropyltryptamine (5-MeO-MiPT): 5-MeO-MiPT or "moxy" was marketed as a "plant fertilizer." Oral doses ranged from 1–3 mg (light), 3–8 mg (common) and 8–12 mg (strong), with typical 10–20 mg doses if inhaled [22,103]. The principal effects lasted 3–7 h and included a general heightening of awareness, mild euphoria, psychedelic visual effects, such as enhanced colors but also anxiety, nausea, confusion and paranoia. Repke et al. studied if the effects of the drug would differ depending upon the route of administration [104]. If ingested the effects were stimulating, with visual hallucinations prevailing. 5-MeO-MiPT metabolism studied by LC-HRMS/MS identified six phase I metabolites following N-demethylation, O-demethylation, demethylation and hydroxylation and N-oxide formation and hydroxylation of the parent compound and N-O-bis-demethylation of the metabolite 5-OH-MiPT [105].
5-Meo-DIPT, Foxy, or Moxy (5-Meo-MIPT) are tryptamines that are distinct. A lot of people I know that like them think they're very aphrodisiac and much more stimulant and a party drug. My opinion on 5-MeO-MIPT is that it was a very sexual chemical … it feels good to touch things, and that sort of sensation certainly lends itself to sex but I wouldn't call it innately an aphrodisiac.
Their first proprietary compound, MOXY, currently in a 52-person Phase I trial, is designed to be just that, says DiNardo: "A sort of 'psychedelic tofu,' a drug that allows moderate cognitive flexibility, but isn't likely to cause awe or ego dissolution." In other words, MOXY acts as a neutral base that's mild on its own, but intended to combine with other compounds to produce fine-tuned mental states.
