5-MAPB Fumarate

What is 5-MAPB?

5-(2-methylaminopropyl)benzofuran (5-MAPB) is a synthetic empathogen of the substituted benzofuran class of chemicals. Benzofurans generally produce a sense of euphoria, empathy and stimulation as well as mildly hallucinogenic effects. This chemical class includes other chemicals such as 5-APB, 4-APB and 6-APB among others. 5-MAPB is the N-methylated form of 5-APB, analogous to how MDMA is the N-methylated form of MDA.

5-MAPB in particular is known for its empathogenic and euphoric properties. It is generally seen as less stimulating and more entactogenic than 6-APB.

What are the effects of 5-MAPB?

5-MAPB is a triple reuptake inhibitor for the monoamines norepinephrine, dopamine (likely the cause of its stimulating effects) and serotonin (presumably leading to its empathogenic/euphoric effects) as well as being an agonist for the 5-HT2A and 5-HT2B receptors (most likely the cause of its mildly hallucinogenic effects). Some have speculated that 5-MAPB also works as a releasing agent for the previously mentioned neurotransmitters.

Some of the most commonly reported effects are:

  • Empathy, love, and sociability enhancement
  • Focus enhancement
  • Thought acceleration
  • Analysis enhancement
  • Wakefulness
  • Stimulation
  • Memory enhancement
  • Motivation enhancement
  • Euphoria
  • Compulsive redosing
  • Increased music appreciation

Some of the potential side-effects include:

  • Increased heart rate
  • Difficulty urinating
  • Dehydration
  • Appetite suppression
  • Nausea
  • Temporary erectile dysfunction
  • Increased perspiration
  • Nystagmus


5-MAPB is classified as illegal in:

  • Germany
  • Switzerland
  • United Kingdom

This list is not exhaustive, so do your own research into the legal status in your country before ordering!

Not gonna lie I expected to have to wait 3 months if it even arrived with how notoriously bad my country's customs is. It arrived perfectly though in just over a month. Super excited to order again!

So i had the worst experience with them ever. My order was not being able to be tracked down and when I contacted them they told me to check in with the post office myself. I did and got my package although it was empty and there was nothing in the packaging so the day of the party where I was supposed to use my order. did not happen so my friends were all high and I had to sit there sober because of their mistake. Upon contacting them, they replied days after and promise to double the order and send it. Well it did not happen when the order came it had the original order which was not doubled down.(eventhough it was promised ). Anyways I was scammed before so I decided to make a video before opening the package ….and u guessed it. There was nothing in it and it was caught on the camera. I wrote them an email which they have been ignoring from a while after more than a week I’m writing this review and hoping to get atleast my money back! I would suggest to avoid them at all costs!

I have made several orders at this store. Once the package was not delivered to me. Probably the loss of the carrier that delivered the package. Even though the package was not insured against loss, I was sent compensation in the form of a "gift" in the next order. When I pointed it out. The CC team communicates by e-mail, is happy to advise you and always accommodates your requests. The only e-shop that has soul and very good heart. Great shop, great team. Thank you very much.
