5-(2-methylaminopropyl)benzofuran, commonly referred to as 5-MAPB and belonging to the substituted benzofuran chemical class, is a synthetic entactogen. Compounds within this class are renowned for their ability to induce euphoria, stimulate, and produce mild hallucinogenic effects. Notable relatives in this category include 5-APB, 6-APB, and 5-EAPB, all inspired by the chemical structure of MDA. 5-MAPB is essentially the N-methylated counterpart of 5-APB, akin to how MDMA relates to MDA.
This compound is distinguished for its capacity to elicit stimulating, euphoric, and entactogenic sensations, making it a quasi-substitute for MDMA. Consequently, it has gained popularity as a readily accessible research chemical obtainable from online vendors. Its emergence as a designer drug traces back to around 2010.
5-MAPB typically appears in the form of its succinate and hydrochloride salts. It’s worth noting that the hydrochloride salt is approximately 36% more potent by mass, necessitating dose adjustments for users. This information underscores the importance of precise dosage for those considering its use.

5-(2-methylaminopropyl)benzofuran, commonly abbreviated as 5-MAPB, falls within the substituted benzofuran and phenethylamine categories. Its chemical structure comprises an ethylamine chain that is N-methylated, connected to a furan ring, which, in turn, is attached to a central benzene ring. Comparably, it can also be categorized as a derivative of methamphetamine, as the ethylamine chain undergoes alpha methylation similar to methamphetamine’s structure.
Regarding its chemical classification, molecules within the amphetamine family possess a core structure featuring a phenethylamine base. This base consists of a phenyl ring linked to an amino (NH2) group through an ethyl chain, often with an additional methyl substitution at the Rα position. Notably, 5-MAPB’s furan ring contains an oxygen atom situated at the 5 part, a placement generally associated with more stimulating effects, as opposed to the 6 position, which tends to impart a more psychedelic character to substances.


5-MAPB is a triple reuptake inhibitor for the monoamines norepinephrine, dopamine, and serotonin. Additionally, it acts as an agonist for the 5-HT2A and 5-HT2B receptors. There is also speculation that 5-MAPB is a releasing agent for the neurotransmitters above.
Consequently, substances like 5-MAPB are believed to operate by enhancing serotonin, norepinephrine, and dopamine neurotransmitters in the brain. They achieve this by binding to and partially obstructing the transporter proteins responsible for clearing and reuptaking these monoamines from the synaptic cleft. This, in turn, permits the accumulation of serotonin, dopamine, and norepinephrine within various regions of the brain associated with reward and cognitive processes. As a result, users may experience stimulating and euphoric effects.

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 PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of scepticism. 

It is also worth noting that these effects will not necessarily occur predictably or reliably, although higher doses are more liable to induce the full spectrum of products. Likewise, adverse effects become increasingly likely with higher doses, including addiction, severe injury, or death ☠.


  • Stimulation – Regarding its effects on the user’s physical energy levels, 5-MAPB is commonly regarded as significantly less stimulating and energizing than MDMA while retaining its core entactogenic products. Unlike MDMA, which encourages activities such as running, climbing and dancing in a way that makes it a popular choice for musical events such as festivals and raves, the distinct style of stimulation that 5-MAPB presents can be described as mildly to moderately forced, trending more towards sedation and relaxation. This means that at higher doses, it becomes difficult or impossible to keep still as jaw clenching, involuntary body shakes, and vibrations become present, resulting in an extreme unsteadiness of the hands and a general lack of motor control, though to a far lesser degree than with MDMA.
  • Increased heart rate
  • Dehydration
  • Appetite suppression
  • Nausea
  • Temporary erectile dysfunction
  • Increased perspiration
  • Nystagmus





The toxicity and long-term health consequences of recreational 5-MAPB use have yet to undergo comprehensive scientific study, and the precise toxic dosage remains unknown. This uncertainty stems from the limited history of human usage associated with 5-MAPB. While anecdotal reports from individuals within the community who have experimented with 5-MAPB at low to moderate doses suggest minimal adverse health effects when used cautiously, it is essential to exercise caution as no guarantees can be provided.

It’s worth noting that 5-MAPB’s notable activation of the serotonin-2b (5-HT2b) receptor, a receptor linked to cardiovalvulopathy, implies potential cardiotoxicity with prolonged use, similar to other substances that stimulate 5-HT2B receptors, such as fenfluramine and MDMA.

For individuals considering using 5-MAPB, it is highly advisable to employ harm reduction practices.

Tolerance and Addiction Potential

As with other entactogenic stimulants, chronic use of 5-MAPB can be moderately addictive, posing a high risk of abuse and the potential for psychological dependence in certain users. Once addiction develops, individuals may experience cravings and withdrawal symptoms if they abruptly cease usage.

Over time and with repeated administration, tolerance to many of 5-MAPB’s effects tends to develop. Consequently, users may need to increase their doses to achieve the same impact progressively. Tolerance reduction typically takes about 3 to 7 days to reach half and 1 to 2 weeks to return to baseline, assuming no further consumption. It’s important to note that 5-MAPB induces cross-tolerance with all dopaminergic stimulants, meaning that the effectiveness of all stimuli is reduced after 5-MAPB use.


Excessive and prolonged consumption of compounds within the amphetamine chemical class, such as 5-MAPB, can potentially lead to stimulant psychosis characterized by symptoms like paranoia, hallucinations, or delusions. Recovery from such psychosis can be incomplete, with approximately 5–15% of users failing to regain normal functioning fully. Antipsychotic medications have been reported to alleviate symptoms of acute amphetamine-induced psychosis effectively. It’s essential to recognize that psychosis very rarely arises from therapeutic use.

Dangerous Interactions

Caution must be exercised when combining 5-MAPB with other substances, as certain combinations pose significant risks. It is imperative to conduct independent research and exercise vigilance to ensure the safety of any variety. Some known dangerous interactions include:

  • 25x-NBOMe & 25x-NBOH: These compounds are highly stimulating and physically demanding. Combining them with 5-MAPB should be strictly avoided due to the risk of excessive stimulation, heart strain, increased blood pressure, vasoconstriction, panic attacks, thought loops, seizures, and even heart failure in extreme cases.
  • Alcohol: Combining alcohol with stimulants can be hazardous, as stimulants can mask the depressant effects of alcohol, potentially leading to over-intoxication. After the stimulant effects wear off, the depressant effects of alcohol can cause blackouts and severe respiratory depression. If combining the two, users should strictly limit their alcohol consumption.
  • DXM: Combining DXM with 5-MAPB should be avoided due to its inhibitory effects on serotonin and norepinephrine reuptake. This combination increases the risk of panic attacks, hypertensive crisis, or serotonin syndrome when used with serotonin releasers like MDMA, methylone, or mephedrone. Careful blood pressure monitoring is essential, and strenuous physical activity should be avoided.
  • MDMA: Combining MDMA with 5-MAPB may amplify neurotoxic effects and increase the risk of high blood pressure and heart strain (cardiotoxicity).
  • MXE: Reports suggest that combining MXE with 5-MAPB may dangerously raise blood pressure and increase the risk of mania and psychosis.
  • Dissociatives: Both 5-MAPB and dissociatives risk inducing delusions, mania, and psychosis, which may be exacerbated when combined.
  • Stimulants: Combining 5-MAPB with other stimulants like cocaine can lead to dangerous heart rate and blood pressure increases.
  • Tramadol: Tramadol is known to lower the seizure threshold, and when combined with stimulants, it may further increase this risk.
  • MAOIs: Combining 5-MAPB with MAOIs can lead to dangerously elevated levels of neurotransmitters like dopamine, potentially resulting in life-threatening situations. Examples of MAOIs include Syrian rue, banisteriopsis caapi, and certain antidepressants.

Serotonin Syndrome Risk

Combinations with specific substances can cause dangerously high serotonin levels, resulting in serotonin syndrome, which requires immediate medical attention and can be fatal if left untreated. These include:

  • MAOIs like banisteriopsis caapi, Syrian rue, phenelzine, selegiline, and moclobemide.
  • Serotonin releasers include MDMA, 4-FA, methamphetamine, methylone, and αMT.
  • SSRIs like citalopram and sertraline.
  • SNRIs like tramadol and venlafaxine.
  • 5-HTP.
