5-MeO-DiBF (5-methoxy-N,N-diisopropylbenzofuranethylamine) is a synthetic psychedelic of the benzofuran class. It is the direct structural analog of 5-MeO-DiPT, with oxygen replacing the nitrogen in the ring.[1] It activates serotonin receptors in the brain, producing the mild visual and tactile shifts characteristic of low-dose tryptamines.[2]

It appeared on the grey-market research chemical market around September 2015, likely developed as a legal alternative after its parent compound was banned.[3] Forensic laboratories in Slovenia first confirmed its identity in December 2015, and it was formally reported to Europe's drug monitoring system.[4] It has since attracted almost no research, and as of 2026, remains outside formal drug scheduling in most countries.

Subjective effects include mild visual enhancement, tactile enhancement, sexual arousal, and mood elevation.[3] The experience is defined by its body emphasis — sexual arousal and physical sensation dominate, while the cognitive and visual qualities remain subdued even at higher doses. Tremor and strong sensitivity to mood and surroundings are characteristic unsought effects.

Physical dependence has not been documented; tolerance builds rapidly like other serotonergic psychedelics,[2] but the parent compound causes persistent brain DNA damage in rodents,[5] and whether 5-MeO-DiBF shares this risk is unknown. Combining it with monoamine oxidase inhibitors or tramadol can trigger dangerous overheating, muscle rigidity, and seizures. Almost nothing is known about this compound specifically — understanding rests on four user reports and grey-market spectral data.[6]

History[edit]

History

Market emergence

5-MeO-DiBF belongs to a family of benzofuran analogs created by replacing the indole nitrogen in established tryptamines with an oxygen atom. Its parent compound, 5-MeO-DiPT, was placed into Schedule I in September 2004.[7][8] The benzofuran version appeared on the research chemical market around September 2015, likely motivated by this ban.[3]

Forensic identification

A laboratory in Slovenia made the first confirmed identification on December 23, 2015, formally notifying the EMCDDA Early Warning System.[1][4] Chapman (2017) published spectral data confirming that grey-market samples matched the labelled compound.[6] This is the only published analytical characterization of 5-MeO-DiBF.

Current status

As of 2026, 5-MeO-DiBF has not entered formal pharmacological investigation. Four experience reports on Erowid are the entirety of publicly available experiential documentation.[3]

Chemistry[edit]

Chemistry

Structural class

5-MeO-DiBF is a substituted benzofuran-ethylamine. The benzofuran ring is a modified version of the indole found in classical tryptamines — oxygen replaces the indole nitrogen, preserving the flat aromatic scaffold while removing a hydrogen-bond site.[1] A 5-methoxy group and two isopropyl groups on the amine mirror 5-MeO-DiPT exactly. Its molecular formula is C₁₇H₂₅NO₂ (275.4 g/mol), and the molecule is lipophilic enough to cross the blood-brain barrier efficiently.

It is chemically distinct from the APB entactogens — 5-APB, 6-APB, 5-MAPB — which attach the aminoalkyl chain at a different ring position and act as monoamine releasers rather than direct serotonin receptor agonists.[10]

Pharmacology[edit]

Pharmacology

No published receptor binding, functional assay, or pharmacokinetic data exist for 5-MeO-DiBF. All pharmacological information is inferred from the structural analog 5-MeO-DiPT and from class-level tryptamine pharmacology. inferred

Mechanism of action

5-MeO-DiBF is presumed to activate serotonin receptors based on its structural similarity to 5-MeO-DiPT. In studies of the parent compound, one serotonin receptor subtype drives the hallucinogenic effects — blocking it eliminates the behavioral signature in animals, while blocking others has no effect.[2]

5-MeO-DiPT also blocks the SERT — the pump that clears serotonin from synapses — with potency comparable to cocaine, without reversing the transporter the way MDMA does.[11] In animal models, it raises dopamine, serotonin, and glutamate across multiple brain regions.[5]

Pharmacokinetics

No human or animal pharmacokinetic data exist for 5-MeO-DiBF. inferred

The two bulky isopropyl groups protect the molecule from monoamine oxidase — the enzyme that degrades simpler tryptamines like DMT and blocks oral activity.[12][9] This is why 5-MeO-DiBF is orally active. People who metabolize drugs slowly through the CYP2D6 liver enzyme may accumulate higher blood levels than expected.[13]

Neuroscience[edit]

Neuroscience

Where it acts

As a presumed serotonin receptor agonist, 5-MeO-DiBF is expected to activate neurons in the prefrontal cortex — the cellular trigger for serotonergic psychedelic effects. inferred The parent compound simultaneously raises dopamine, serotonin, and glutamate across multiple brain regions[5] and blocks serotonin reuptake,[11] suggesting a more complex profile than pure receptor activation.

Neurotoxicity and phenomenology

The mild psychedelic effects suggest weaker cortical engagement than more potent compounds. The prominent sexual arousal — shared with 5-MeO-DiPT — may reflect preferential activity in subcortical serotonergic circuits involved in sexual function.

The parent compound's neurotoxicity is a significant concern. 5-MeO-DiPT causes DNA strand breaks persisting up to 60 days in rat brain tissue, with accompanying damage to dopamine-producing cells.[5] Repeated adolescent exposure impairs learning in a pattern consistent with lasting serotonergic disruption.[14] Whether 5-MeO-DiBF shares these effects is unknown.

Subjective Effects[edit]

Summary

Subjective Effects

5-MeO-DiBF produces a mild psychedelic experience with a strong body emphasis. Sexual arousal and tactile awareness dominate the foreground. Cognitive disruption and visual distortion remain subdued — even at higher doses, the compound does not produce ego dissolution or immersive inner experiences.

In comparative terms, 5-MeO-DiBF sits far below its parent compound 5-MeO-DiPT in both potency and depth, requiring roughly 5–10 times the dose for comparable effects.[3] The experience resembles a low-dose tryptamine rather than the immersive psychedelia of psilocybin or DMT.

Effect Grid

Dose Level:
Description

At common doses (80–110 mg oral), 5-MeO-DiBF's characteristic profile becomes fully apparent. Visual enhancement is moderate: color alteration and color enhancement are noticeable, with mild visual drifting of surfaces and textures. The psychedelic headspace remains notably subdued compared to other tryptamines at equivalent experiential intensity — cognitive effects like analysis enhancement and conceptual thinking are present but faint.

The somatic signature dominates: a clear body high, moderate stimulation, and prominent sexual arousal enhancement — the latter disproportionately strong relative to the visual and cognitive components. Touch enhancement is marked. Temperature dysregulation and mild involuntary body movements (tremor) may occur. Nausea is possible but typically mild.

Time alteration is noticeable. Total duration is 4–6 hours. The experience is often described as "mild" relative to expectations set by the tryptamine class.

Safety

5-MeO-DiBF has no published toxicological data. All safety information is drawn from structural analogy with 5-MeO-DiPT and class-level serotonergic psychedelic pharmacology. The absence of adverse event reports does not constitute evidence of safety.

Toxicity

No lethal dose or toxic dose data have been published for 5-MeO-DiBF in any species. No human overdose cases exist. A comprehensive review of novel psychoactive substance adverse events from 2017–2020, covering over 1,300 cases, did not include 5-MeO-DiBF.[15]

Neurotoxicity (analog data)

The structural parent 5-MeO-DiPT causes significant brain damage in rodent models. At tested doses, it produces DNA strand breaks persisting up to 60 days, with accompanying damage to dopamine-producing nerve terminals.[5] Repeated adolescent exposure causes lasting learning impairment consistent with long-term serotonergic disruption.[14] Direct cell toxicity has been observed at high concentrations in laboratory cell cultures, independent of SERT expression.[11] safety citation needed

Whether 5-MeO-DiBF shares this neurotoxic potential cannot be determined without substance-specific studies.

Cardiovascular considerations

No cardiovascular data exist for 5-MeO-DiBF. As a class effect, serotonin receptor agonists can raise heart rate and blood pressure. User reports noted tremor but no cardiovascular adverse events at documented doses.[16] safety citation needed

Psychological Risks

Like other serotonergic psychedelics, 5-MeO-DiBF can produce anxiety, panic, and temporary psychotic-like effects at any dose — particularly in people predisposed to psychotic conditions. The mild experiential profile may reduce but does not eliminate this risk.

  • Acute distress: Anxiety and panic are possible at any dose, especially in individuals with a predisposition to psychotic-spectrum conditions.
  • Hallucinogen persisting perception disorder (HPPD): No cases reported for 5-MeO-DiBF. The risk is theoretically present for any serotonin receptor agonist.
  • Psychosis: No cases documented. Serotonin receptor activation carries inherent psychosis risk in vulnerable individuals.

Tolerance & Dependence

No published tolerance or dependence data exist for 5-MeO-DiBF. inferred

Rapid tolerance is a defining feature of serotonergic psychedelics. It builds immediately after ingestion, driven by serotonin receptor desensitization, and is expected to reset within approximately 7 days.[17] Cross-tolerance with other serotonergic psychedelics — LSD, psilocybin, mescaline — is expected.[2][18]

Physical dependence is not expected. Tryptamines consistently show low abuse liability in laboratory models.[19]

Drug Interactions

No drug interaction studies have been conducted for 5-MeO-DiBF. All assessments are inferred from its predicted serotonergic mechanism. inferred

Serotonin syndrome risk

5-MeO-DiBF activates serotonin receptors and likely blocks serotonin reuptake. Combining it with other serotonergic drugs can cause excessive serotonin buildup — dangerous overheating, muscle rigidity, and seizures.[20][21]

Tramadol: Classified as dangerous. Tramadol blocks serotonin reuptake and has been implicated in fatal serotonin syndrome when combined with other serotonergic drugs.[22]

MAO inhibitors: Combining any serotonergic tryptamine with monoamine oxidase inhibitors (phenelzine, tranylcypromine, moclobemide) risks severe blood pressure spikes and life-threatening serotonin syndrome.[22]

SSRIs and SNRIs: Additive serotonergic risk. SSRIs may also blunt psychedelic effects. safety citation needed

CYP2D6 inhibitors: If 5-MeO-DiBF is metabolized by CYP2D6 as predicted,[13] drugs that block this enzyme (fluoxetine, paroxetine, bupropion) could raise blood levels unpredictably.

Cannabis: Unknown. No published data.

In the event of suspected serotonin toxicity: discontinue all serotonergic agents, contact emergency services immediately, and provide supportive care. Cyproheptadine (a drug that blocks serotonin receptors) has been used as an antidote in clinical settings, though evidence for its efficacy remains limited.[23]

Contraindications

No published contraindications specific to 5-MeO-DiBF exist. The following are inferred from class-level serotonergic psychedelic pharmacology: inferred

  • Personal or family history of psychotic-spectrum disorders (schizophrenia, schizoaffective disorder, bipolar I with psychotic features): Serotonin receptor activation carries inherent psychosis risk. Absolute contraindication.
  • Concurrent MAO inhibitor use: Risk of severe serotonin syndrome and dangerous blood pressure crisis. Absolute contraindication.
  • Concurrent tramadol use: Elevated serotonin toxicity risk.[22] Absolute contraindication.
  • Concurrent SSRI or SNRI use: Additive serotonergic risk; unpredictable effects. Relative contraindication.
  • Concurrent CYP2D6 inhibitor use: Potential for elevated blood levels.[13] Relative contraindication.
  • Pregnancy and lactation: No reproductive toxicity data exist. safety citation needed
  • Severe heart conditions: Sympathomimetic effects pose theoretical risk. safety citation needed

Harm Reduction[edit]

AppearanceNot recorded+ add appearance
Red FlagsNot recorded+ add red flags

5-MeO-DiBF has no independent analytical testing data from drug checking services, making identity and purity verification especially important. Standard reagent testing can help distinguish it from more dangerous substitutions, but the absence of published reference reactions means results require careful interpretation.

Volumetric dosing from an accurately weighed stock solution is strongly recommended over estimating powder quantities by eye. No standardized formulations exist.

Guidelines

  • Test every sample with at least two reagent kits before use
  • Weigh doses with a milligram-precision scale — never estimate by eye
  • Start at the lowest reported active dose and wait the full expected onset period before considering additional material
  • Have a sober, trusted person present for first experiences
  • Prepare the physical space: comfortable temperature, accessible water, quiet environment
  • Avoid combining with other substances, especially on a first experience
  • Eat lightly several hours beforehand to reduce nausea risk
  • Set aside the full day — plan no obligations for at least 8 hours including aftereffects

Set & Setting

5-MeO-DiBF is reported to be highly sensitive to set and setting.[3] A familiar, comfortable, and private environment is advisable — particularly given the prominent sexual arousal effects, which may be unwelcome in social settings.

A sober, trusted companion is recommended for first experiences. The mild experiential ceiling does not eliminate the risk of unexpected anxiety or disorientation.

Aftercare & integration. The mild experiential profile means most users will not require intensive integration. However, any psychedelic experience — even a subtle one — can surface unexpected emotional material.

In the days following use, note any shifts in mood, sleep, or perception. Journaling while observations are fresh can be useful. If unusual perceptual phenomena (visual trails, pattern persistence) or mood disturbances last more than a few days, consult a healthcare professional. The near-total absence of safety data for this compound means any persistent aftereffects should be taken seriously.

Recovery & Support

5-MeO-DiBF carries low abuse liability by class inference. If use of this or other psychoactive substances has become a source of distress or is interfering with daily functioning, support is available.

  • SAMHSA National Helpline: 1-800-662-4357 (US, free, confidential, 24/7)
  • Fireside Project: 62-FIRESIDE (psychedelic peer support)
  • Global Drug Survey: highway.org.au (international resources)

Professional support from a therapist experienced with substance use or psychedelic integration can help contextualize difficult experiences.

Emergency Response

Recognizing an emergency: Uncomfortable effects such as mild anxiety, nausea, or tremor are not emergencies. Seek immediate help if any of the following occur: chest pain, seizure, loss of consciousness, extremely tachycardia that does not slow with rest, severe confusion or inability to communicate, or any sign of self-harm.

Immediate steps:

  • 1. Call emergency services
  • 2. Keep the person calm and in a safe position — seated or in the recovery position if vomiting or losing consciousness
  • 3. Do not restrain them unless they are in immediate danger of harming themselves
  • 4. Do not induce vomiting
  • 5. Monitor breathing continuously

What to tell the dispatcher: Name the substance (5-MeO-DiBF, a synthetic benzofuran psychedelic), approximate amount taken, time of ingestion, and current symptoms. Good Samaritan laws in many jurisdictions protect people who call for help during a drug-related emergency.

No specific reversal agent exists for serotonergic psychedelics. If serotonin syndrome is suspected (rigid muscles, high fever, agitation, rapid heart rate), cyproheptadine may be administered in a clinical setting.[23]
