5-APB (Benzo) Review


There are many lesser-known substances out there, and 5-APB (Benzo) is one of them. This compound is a phenethylamine derivative that’s structurally similar to MDA. Often, it’s categorized as a benzofuran compound, and it’s an entactogen (psychoactive). It has effects comparable to MDMA, and it’s a popular option for people who want a more intense and euphoric high. In this article, we’ll go over the history, dosage, user reviews, and potential side effects of 5-APB.

General Information on 5-APB (Benzo)

Let’s begin our 5-APB (Benzo) review with general information on this drug. It’s a synthetic drug also known as “6-(2-aminopropyl) benzofuran.” It’s classified as a “research chemical,” which means it’s not approved for human use by regulatory entities. Instead, it’s mostly used for scientific and medical research. Evidently, it may produce psychoactive effects in humans, like increased energy, euphoria, and altered perception.

Similar drugs are 6-APB and 5-MAPB, but they don’t quite have the same stimulating and euphoric effects as 5-APB. Thanks to online research chemical vendors, users have a way to purchase the 5-APB research chemical. However, its legal status has yet to be determined in many countries. It’s already off the list of legal drugs in countries like the US, Brazil, Japan, Switzerland, and the UK.

History of 5-APB (Benzo)

As the next part of our research chemical review, we’ll cover this drug’s history. The first known instance of 5-APB (Benzo) was in 1993, when the pharmaceutical company, Upjohn, synthesized it. However, it wasn’t until 2004 that 5-APB became popular among the recreational drug community. It first popped up on the online market in 2010, where it was sold as a research chemical.

Since then, the compound has been subject to various legal regulations, as mentioned above. Regardless, it remains popular among people looking for legal highs, or at least semi-legal ones, depending on location. Its chemical structure continues to be studied by researchers interested in making new psychoactive mixes.

Dosage and Administration

As with any drug, proper dosage and administration help prevent harmful effects. The recommended dose of the 5-APB research chemical varies depending on how the user administers it. Usually, doses range between 20mg and 100mg.

Oral Administration

The most common method of taking 5-APB is through oral administration. The recommended dose for oral consumption is between 80-120mg, and the effects can last up to 8 hours. The duration of the effects varies depending on the user’s metabolism, tolerance, and dose.

Nasal Insufflation

Nasal insufflation is when a user snorts the compound through the nostrils. This method generally leads to a faster onset of effects and a shorter duration. The recommended dosage for nasal insufflation is lower than for oral administration, ranging from 50-75mg.


Vaporizing 5-APB isn’t common. However, it may produce a faster onset of effects and a shorter duration. The process of vaporization involves heating up the compound to make a vapor that’s inhaled. The recommended amount for vaporization is 50-75mg.


Suppositories, which involve inserting the drug through the rectum, are an uncommon method. It may produce a longer duration of effects compared to oral administration. The dosage for suppository use is usually between 100-150mg.


Redosing refers to taking additional doses after the user takes the initial dose. It’s not recommended to redose within the same session. That’s because it can increase the risk of adverse side effects and may harm the user’s health.

User 5-APB (Benzo) Reviews

As with any drug, user reviews can supply practical insights into the experiences of those who’ve taken 5-APB. Users report various effects, including increased energy, euphoria, enhanced empathy, and altered perception. Some users describe feeling more sociable and outgoing, while others report a sense of introspection and increased self-awareness.

Onset of Effects

The onset of effects of 5-APB (Benzo) can vary depending on the method of administration. Oral consumption can take 90 minutes to take effect. In contrast, nasal insufflation and vaporization may take 15-30 minutes.


The primary effect of the 5-APB research chemical is intense euphoria and more energy. Users report feeling more social, outgoing, and talkative, with greater empathy toward others. The drug can also produce altered perception and sensory experiences like enhanced colors and music appreciation.


Other reported effects of 5-APB include increased sexual arousal, enhanced sensory perception, and a feeling of increased self-awareness. Some users conveyed a sense of spiritual connectedness and transcendence.

Altered Perception

As reported by users, altered perception is one of the primary effects of 5-APB. It can manifest in many ways, including enhanced sensory experiences, changes in the perception of time and space, and altered thought processes.

For instance, users may experience enhanced colors, textures, and patterns, making the visual environment appear more vivid and intense. Music can also sound more powerful and emotional. Users report a heightened appreciation for the nuances of melodies and beats.

Users may also report feeling a sense of time distortion, with time seeming to either speed up or slow down. This can make events appear to be happening more rapidly or slowly than they actually are. In some cases, users may feel detached from their physical surroundings. They might feel like they’re “floating” or disconnected from reality.

Anticlimax (“Comedown”)

As with other drugs, the effects of 5-APB will eventually wear off, leading to an anticlimax or “comedown” period. During this period, users may feel tired, irritable, and depressed. Depending on the user’s metabolism and dosage, these feelings can last several days.

Potential Side Effects of 5-APB (Benzo)

While 5-APB may have desirable effects, it has risks and side effects. Some of the reported side effects of 5-APB (Benzo) include the following:

  • Increased heart rate and blood pressure
  • Nausea and vomiting
  • Sweating and chills
  • Jaw-clenching and teeth grinding
  • Insomnia and sleep disturbances
  • Hallucinations and paranoia
  • Agitation and anxiety
  • Seizures and convulsions

Notably, the long-term effects of the 5-APB research chemical are unknown, and research is ongoing to understand its potential risks fully. If any explorers are looking for legal highs, it’s best to check with your local jurisdiction. Always be cautious when experimenting with a novel psychoactive substance like 5-APB.
