5-MeO-DiPT
5-MeO-DiPT, also known as 5-methoxy-N,''N-diisopropyltryptamine and sometimes as foxy methoxy or simply foxy, is an atypical psychedelic drug of the tryptamine and 5-methoxytryptamine families. It has unique and distinct effects from other serotonergic tryptamines, including some stimulant- and entactogen-like effects, robust tactile and sexual enhancement, and only light hallucinogenic effects. The drug is usually taken orally, but may also be used by other routes.
It acts as a non-selective serotonin receptor agonist, including of the serotonin 5-HT1A and 5-HT2A receptors among others. Uniquely among most tryptamines, the drug has been found to produce serotonergic neurotoxicity and associated cognitive deficits in rodents reminiscent of but distinct from those observed with MDMA. Various severe and/or fatal intoxications associated with 5-MeO-DiPT have been reported in humans. It is the 5-methoxy derivative of diisopropyltryptamine and is an analogue of other psychedelic tryptamines like 4-HO-DiPT, 5-MeO-DMT, and 5-MeO-MiPT.
5-MeO-DiPT was first described in the literature by Alexander Shulgin and colleagues in 1980. Subsequently, Shulgin described 5-MeO-DiPT in further detail in his 1997 book TiHKAL''. The drug was first encountered as a novel designer drug in 1999. It is used recreationally as a "party drug" and sexual enhancer, with notable use among gay men and transgender women as part of "chemsex", although its use in general has declined over time and is rare. 5-MeO-DiPT became a controlled substance in the United States in 2003. The closely related drug 5-MeO-MiPT has similar effects as 5-MeO-DiPT, remains legal in the United States and many other countries, and is often used as a substitute for 5-MeO-DiPT.
Use and effects
In his book TiHKAL and other publications, Alexander Shulgin reported the dose of 5-MeO-DiPT to be 6 to 12mg orally, its onset to be 20 to 30minutes or within 1hour, its time to peak effects to be 1 to 1.5hours, and its duration to be 4 to 8hours. However, in other publications besides TiHKAL he gave a dose range of 6 to 10mg or a dose range of 8 to 12mg. According to Shulgin, testing of 5-MeO-DiPT started at a dose of 0.1 mg and gradually titrated up in 10 human volunteers, with threshold effects occurring at a dose of 4mg orally and full effects occurring at doses of 6mg or more. The drug's has been described as "fast-acting" and its duration has also been reported to be "short-lived" and as brief as 3 to 6hours. In addition to oral administration, 5-MeO-DiPT has been reported to be used less commonly by smoking, insufflation, or intravenous injection. Forms known to be used include powder, tablets, and capsules.The psychedelic or perceptual effects of 5-MeO-DiPT have been reported to include colors on edges of eyesight, color contrasts and sparkle, altered facial perception, sensory distortion, few if any visual enhancements, some closed-eye imagery but only at high doses, feelings of strangeness, objects having special significance, some musical sound distortions reminiscent of those of DiPT, music sounding strange and fake, time dilation, having only mild hallucinogenic effects, outgoing rather than inwardly reflective intellectual activation, lack of intuitive leaps, and a wave-like experience wherein the effects "waved in and out". Affective and behavioral effects have included stimulation, some entactogen-like effects, talkativeness, disinhibition, emotional enhancement, opening of affect, easy emotional expression, easy communication with others, reduced guards and reservations, relaxation, feeling happy, mild euphoria, and mellowness. In addition, the drug has been reported to produce tactile or sensual enhancement, one's body feeling alive and alert, feeling like waves are passing back and forth over one's body, awareness of vibrations, feeling sexually aroused, and "dramatic" erotic or sexual enhancement.
Negative emotional and behavioral effects have included uncomfortableness, agitation, feeling unnerved, paranoia, and social avoidance, but no hangover. 5-MeO-DiPT has been described as having minimal physical side effects and as being relatively free of autonomic side effects and indicators of toxicity. Reported physical side effects have included body load and discomfort, slight pupil dilation, mild nausea, some muscular hyperreflexia, muscle contractions and spasms, gastrointestinal disturbances, hypertension, and little change in appetite or sleep disruption. The effects of 5-MeO-DiPT have been described as either being "positive" or a "mixed bag". User responses are said to vary dramatically, with some people finding it appealing, sexual, invigorating, interesting, and enjoyable, and others finding it nauseating, annoying, diarrhea-inducing, and generally unpleasant.
5-MeO-DiPT has been described as LSD-like in some ways but as being quite different from other psychedelics. Descriptions have included the drug never being psychedelic in the way of classical psychedelics like LSD and psilocybin, there being an absence of intense sensory disturbances or hallucinogenic effects as with other psychedelics like dimethyltryptamine and psilocybin, never feeling as though one was having a psychedelic experience, and being able to function normally on a social level including at public events even at high doses. However, one user who took a high dose described reaching a "plus-three" on the Shulgin Rating Scale in a very LSD-like manner but without the visuals. Higher doses may produce more psychedelic effects, but the drug is still described as not that psychedelic even at such doses. Despite its lack of robust hallucinogenic effects at typical doses, 5-MeO-DiPT is described as nonetheless producing quite profound emotional and intellectual modifications.
5-MeO-DiPT is reported to differ in its subjective effects from the structurally related DiPT in most respects but to share some auditory effects with this drug. In terms of these effects, whereas DiPT caused harmonic distortion of heard sounds, 5-MeO-DiPT caused changes in musical character and interpretation without apparent changes in harmonic structure. As such, while both produced auditory effects, DiPT and 5-MeO-DiPT caused different distortions of musical interpretation. 5-MeO-DiPT has been described as a "psychedelic stimulant" and has a reputation as a "sexual enhancer" or "aphrodisiac". Among its effects, the pro-sexual effects of 5-MeO-DiPT have been especially highlighted, with these effects being present at low doses. Users have remarked that it took them to a "marvelous sexy place", that "everything shaded with eroticism", that the "erotic world was fantastic, explosive, almost scary", and that the drug may vie with 2C-B as a sexual enhancer or that it left 2C-B "in the dust" in this regard.
5-MeO-DiPT has been described as having effects similar to those of 5-MeO-MiPT and these drugs as having unique and distinct effects from those of other psychedelic tryptamines. They are reported to be very pro-sexual, much more stimulant, and more like party drugs than other tryptamines. While 5-MeO-DiPT and 5-MeO-MiPT are described as pro-sexual, they may not be innately aphrodisiac but instead may produce tactile enhancement in a way that lends itself to sex. The tactile enhancement and "body high" with 5-MeO-DiPT and 5-MeO-MiPT may in part be why they have been compared to entactogens like MDMA. 5-MeO-DiPT has been described as being closer to MDMA in its effects than to psychedelic tryptamines and that the effects are a "body high kind of thing". The drug is also known to be combined with other drugs such as MDMA.
Side effects
s have been reported with 5-MeO-DiPT. There is a report of a prolonged delusional state associated with 5-MeO-DiPT.Overdose
Excessive doses or overdose have caused clinical intoxication, characterized by nausea, vomiting, agitation, hypotension, mydriasis, tachycardia, and hallucinations, in a number of young adults. A number of these overdoses are attributed to the drug's delayed onset of action, where first time users, who were unfamiliar with the drug, administered a second dose after initially feeling no effects. Rhabdomyolysis and renal failure occurred in one young man and another one died 3 to 4hours after an apparent rectal overdose. There have been a number of published cases of severe and/or fatal intoxication with 5-MeO-DiPT.Interactions
The effects of 5-MeO-DiPT may be potentiated when used in combination with cannabis.Pharmacology
Pharmacodynamics
5-MeO-DiPT acts as a non-selective serotonin receptor agonist, including of the serotonin 5-HT1A, 5-HT1B, 5-HT1D, 5-HT2A, 5-HT2B, and 5-HT2C receptors, among others. It has shown variably strong preference for the serotonin 5-HT1A receptor in terms of binding affinity, with 2-fold, 25-fold, >76-fold, and 161-fold higher for this receptor over the serotonin 5-HT2A receptor in different studies. However, in terms of receptor activation, 5-MeO-DiPT showed similar potency at the serotonin 5-HT1A receptor and the serotonin 5-HT2A receptor and had several-fold preference for these receptors over the serotonin 5-HT2C receptor.In addition to its direct serotonin receptor interactions, 5-MeO-DiPT is a serotonin [reuptake inhibitor] with potency ranging from similar to its serotonin 5-HT2A receptor agonism to very low in different studies. Conversely, it does not significantly affect dopamine or norepinephrine reuptake and shows no activity as a monoamine releasing agent. The drug can block the serotonin release induced by methamphetamine in vitro. 5-MeO-DiPT can elevate brain serotonin levels in rodents, presumably via its serotonin reuptake inhibition. The elevations in serotonin levels caused by 5-MeO-DiPT may be limited by its concomitant serotonin 5-HT1A receptor agonism, as serotonin 5-HT1A receptors serve as inhibitory autoreceptors that limit serotonin release. By an unknown mechanism, but possibly serotonin 5-HT2A receptor agonism, 5-MeO-DiPT may also elevate brain dopamine levels in rodents, including in the prefrontal cortex, striatum, and/or nucleus accumbens, although findings are mixed. The mechanism of action of the psychedelic effects of 5-MeO-DiPT is thought to be serotonin 5-HT2A receptor agonism, but its full mechanism of action is unclear and additional mechanisms may also be involved.
5-MeO-DiPT produces the head-twitch response, a behavioral proxy of psychedelic-like effects, in rodents. As with many other psychedelics, this follows an inverted U-shaped dose–response curve. The head-twitch response induced by 5-MeO-DiPT is blocked by serotonin 5-HT2A receptor antagonists such as volinanserin. 5-MeO-DiPT's head-twitch response is described as robust but also weak and much lower in magnitude than that produced by other serotonergic psychedelics such as 5-MeO-DMT or DOM. The serotonin 5-HT1A receptor agonism of 5-MeO-DiPT may inhibit its serotonin 5-HT2A receptor-mediated head-twitch response. 5-MeO-DiPT partially substitutes for LSD in rodent drug discrimination tests, with 52% responding at 1mg/kg, 75% responding at 3mg/kg, and behavioral disruption at higher doses. In addition, it substitutes for DOM in rodent drug discrimination tests. The stimulus properties of 5-MeO-DiPT in LSD substitution tests are completely and insurmountably blocked by the serotonin 5-HT2A receptor antagonist volinanserin. Conversely, they are partially and surmountably blocked by the serotonin 5-HT1A receptor antagonist WAY-100635. Besides psychedelic-like effects, 5-MeO-DiPT also produces hypolocomotion and hypothermia in rodents and potentiates the forepaw treading induced by the serotonin 5-HT1A receptor agonist 8-OH-DPAT.
