Buyers interested in MDAI typically scour the internet for reputable vendors and sources, considering factors like purity, price, and shipping options. The online marketplace offers various choices, allowing buyers to make informed decisions based on their research needs.
Despite its classification as a research chemical, MDAI’s market presence has led to varying scrutiny from regulatory bodies in different regions. Consequently, the availability and legality of MDAI can fluctuate, with some areas implementing restrictions or bans while others permit its sale for research purposes.


5,6-Methylenedioxy-2-aminoindane, commonly referred to as MDAI, is a relatively lesser-known entactogen belonging to the aminoindane class. It is recognized for its unique properties as a selective serotonin-releasing agent (SSRA) with minimal impact on dopamine and norepinephrine neurotransmitters.
MDAI was initially developed by the American medicinal chemist and pharmacologist David E. Nichols in the 1990s while at Purdue University. In the 2010s, MDAI gained attention and found its place in the online research chemical market, often alongside other novel entactogens like 5-MAPB, 5-APB, and 6-APB. During this time, it was marketed as a legal, grey-market alternative to MDMA. Moreover, researchers are exploring its potential application as an alternative to conventional entactogens in treating mental health conditions such as anxiety and depression.
Users of MDAI report a range of subjective effects, including sedation, muscle relaxation, enhanced tactile perception, anxiety alleviation, increased empathy, sociability, and euphoria. It is often likened to producing the non-stimulating effects characteristic of prototypical entactogens like MDMA and MDA. Notably, MDAI is believed to have reduced invigorating, highly prosocial, or intensely euphoric results, potentially offering the advantage of reduced neurotoxicity and fewer side effects. Nevertheless, further research is essential to substantiate these claims.
Given the limited available data regarding MDAI’s pharmacological properties, metabolism, and toxicity, it is strongly recommended that individuals considering its use harm reduction practices be employed.

MDAI, scientifically known as 5,6-methylenedioxy-2-aminoindane, is a synthetic compound classified within the aminoindane family and shares structural similarities with amphetamines. In its molecular structure, MDAI possesses the R3 terminal carbon of the amphetamine’s propane chain, which is bonded to a benzene ring. This unique arrangement forms an indane group characterized by the fusion of a benzene ring with a pentane ring. Notably, MDAI incorporates an amino group (NH2) attached to R2 of the indane ring. Additionally, the compound features two oxygen substitutions at R5 and R6, connected via a methylene bridge, thus forming a methylenedioxy group.
MDAI can be likened to its structural relative, 2-AI, with the key distinction being the presence of a methylenedioxy ring within MDAI’s molecular structure.


MDAI can impede serotonin reuptake and demonstrates a particular affinity for serotonin receptors. Scientific investigations have revealed that animals treated with MDAI experience elevated extracellular levels of monoamine neurotransmitters, notably serotonin, within their brains.
In a comparative context, MDAI’s potency in serotonin release is akin to that of MDA but notably less potent than MDMA. This mechanism involves the inhibition of neurotransmitter reuptake and reabsorption after they have fulfilled their role in transmitting neural impulses. Consequently, this inhibition allows these neurotransmitters to accumulate, be recycled, and induce entactogenic effects.

Subjective effects

Disclaimer: The following effects are based on anecdotal user reports and the insights of PsychonautWiki contributors, as documented in the Subjective Effect Index (SEI). They should be approached with a degree of scepticism. It’s important to note that these effects may only sometimes manifest predictably. Higher doses are more likely to induce a broader range of products, and escalating doses increase the risk of adverse effects, including addiction, severe harm, or even fatality ☠.

Physical :

  1. Sedation – A distinguishing feature of MDAI is its tendency to induce moderate sedation, discouraging physically active behaviours like running, dancing, or climbing.
  2. Spontaneous physical sensations – MDAI produces a moderate to extreme euphoric, warm, and tingling sensation that envelops the entire body. This sensation becomes intensely pleasurable at higher doses.

Physical euphoria:

  1. Tactile enhancement
  2. Vibrating vision – At higher doses, eyeballs may exhibit spontaneous rapid movements, causing temporary blurriness and a phenomenon known as nystagmus.
  3. Increased perspiration
  4. Temperature regulation suppression
  5. Dehydration – Dry mouth and dehydration are common effects, driven by an elevated heart rate and a strong urge to engage in vigorous physical activities. To avoid over-drinking, it’s advisable to sip water instead.
  6. Difficulty urinating – Like MDMA, higher doses of MDAI can lead to temporary and harmless difficulty urinating. This is likely due to the anti-diuretic hormone (ADH) release, which regulates urination. Relaxation, warmth application to the genitals, or the sound of running water may alleviate this.
  7. Temporary erectile dysfunction


  • Visual effects are subtle and occur primarily at higher doses, including:
  1. Visual acuity enhancement
  2. Colour enhancement
  3. Tracers


  • The cognitive effects intensify with dosage and are characterized by euphoria, love, and empathy. Essential cognitive products include:
  1. Anxiety suppression
  2. Cognitive euphoria – Strong emotional happiness stemming from serotonin release.
  3. Empathy, affection, and sociability enhancement – Not as pronounced as MDMA but still dominant.
  4. Increased music appreciation
  5. Immersion enhancement
  6. Thought deceleration
  7. Mindfulness
  8. Time distortion


  • Auditory effects may include enhancements and distortions.


  • The post-peak phase, often called the “comedown,” is characterized by adverse and uncomfortable effects due to neurotransmitter depletion. Common after-effects include:
  1. Anxiety
  2. Cognitive fatigue
  3. Depression
  4. Irritability
  5. Motivation suppression
  6. Thought deceleration
  7. Wakefulness


Disclaimer: The information below is based on anecdotal user reports and the collective insights of PsychonautWiki contributors. While valuable, these insights should be approached with caution. Individual reactions may vary, and higher doses carry increased risks, including addiction and severe harm or fatality ☠.

Pharmacology and Toxicity:

  • MDAI and related substances have been widely employed in scientific research because they mimic many of MDMA’s effects without causing neurotoxicity. However, there have been no tests specifically addressing cardiovascular toxicity.[2][3][4][5][6][7][8]
  • The lethal dose of MDAI in humans remains unknown, and the exact toxic dosage is yet to be determined. Due to its action as a serotonin reuptake inhibitor, overdosing may lead to serotonin syndrome.
  • Harm reduction practices are strongly advised when using this substance.

Dependence and Abuse Potential:

  • While formal studies are lacking, MDAI may have a mild addictive potential with a low likelihood of causing psychological dependence in most users. This is due to its unique mechanism of action that does not significantly increase dopamine levels. Those experiencing addiction may encounter cravings and withdrawal symptoms upon cessation.
  • Tolerance to MDAI’s effects develops with sustained use, prompting users to administer larger doses for the same results. Afterwards, tolerance reduction takes approximately 3-7 days to reach half and 1-2 weeks to return to baseline (without further consumption).
  • MDAI demonstrates cross-tolerance with all entactogens, meaning its use will reduce the effects of other serotonergic stimulants.

Dangerous Interactions:

  • Combining psychoactive substances can be perilous, as effects can become life-threatening. Below are some known hazardous interactions. Independent research should always be conducted to ensure safety. Some exchanges are sourced from TripSit:
  1. 25x-NBOMe & 25x-NBOH – Avoid combining 25x compounds with MDAI due to the risk of excessive stimulation, heart strain, high blood pressure, vasoconstriction, panic attacks, thought loops, seizures, and even heart failure in severe cases.
  2. Alcohol – Mixing alcohol with stimulants is dangerous because stimulants mask alcohol’s depressant effects. When the motivation wears off, depressant results can take over, leading to blackouts and severe respiratory depression. If combined, strictly limit alcohol intake.
  3. DXM – Avoid DXM combinations as they inhibit serotonin and norepinephrine reuptake, increasing the risk of panic attacks, hypertensive crisis, or serotonin syndrome with serotonin releasers like MDMA, methylone, or mephedrone. Monitor blood pressure and avoid strenuous activity.
  4. MDMA – Combining stimulants with MDMA may intensify neurotoxic effects, raise blood pressure, and strain the heart (cardiotoxicity).
  5. MXE – Some reports suggest that MXE combinations may dangerously elevate blood pressure and risk mania and psychosis.
  6. Dissociatives – Both classes risk delusions, mania, and psychosis, which may be exacerbated when combined.
  7. Stimulants – Combining MDAI with other stimulants like cocaine can raise heart rate and blood pressure to dangerous levels.
  8. Tramadol – Tramadol lowers the seizure threshold, and combining it with stimulants may further increase this risk.
  9. Cocaine – Combining cocaine with MDAI can excessively strain the heart.

Serotonin Syndrome Risk:

  • Combinations with certain substances can elevate serotonin levels to dangerous levels, potentially causing a life-threatening serotonin syndrome. These substances include:
    • MAOIs – Such as banisteriopsis caapi, Syrian rue, phenelzine, selegiline, and moclobemide.
    • Serotonin Releasers include MDMA, 4-FA, methamphetamine, methylone, and αMT.
    • SSRIs – Such as citalopram and sertraline.
    • SNRIs – Such as tramadol and venlafaxine.
    • 5-HTP
