Eutylone Research Chemical Review


Eutylone is a synthetic cathinone that is commonly abbreviated as bk-EBDB. Unlike naturally occurring cathinones, eutylone is synthesized by humans, though it does share a similar chemical makeup with the organic compound. When administered recreationally, eutylone induces cathinone-like effects like euphoria and improved focus and energy.

This article outlines an overview of the bk-EBDB research chemical, which includes general information, the history of the legal high, information on dosage and administration, other user experiences, and potential side effects.

General Information on Eutylone

Eutylone is classified as a substituted cathinone as a derivative of cathinone, which occurs naturally in the khat plant in Africa. This class of drug is continuously expanding to include new substances as labs work around restrictive legislation, and eutylone itself is thought to have been synthesized as a replacement for a previously legal high that was banned.

Bk-EBDB is often distributed as a powder or in crystalline rocks that are off-white with a cloudy, brown-ish appearance. It’s also sometimes available in the form of capsules or compressed into pills. It may be mixed with other substances and labeled as “bath salts”.

The presence of eutylone may or may not be detected in a drug test as cathinones and substituted cathinones are notoriously difficult to identify. This does not rule out the possibility of detection via urinalysis or blood testing.

History of Eutylone

Eutylone belongs to a group of similar substituted cathinones that was first synthesized in the 1960s. It’s closely related to a compound called ephylone, which was banned in several countries as recently as 2018, giving rise to eutylone as an alternative with similar effects. Eutylone saw a dramatic uptick in global use as recently as 2019, and it has continued to steadily rise in popularity as a recreational legal high since then.

Eutylone currently remains technically legal in many countries, though officials in Sweden contemplated naming it a “hazardous substance” in 2019. As a substituted cathinone and synthetic stimulant, it is subject to prosecution in some countries under blanket laws that outlaw entire classes of substances rather than naming each banned substance individually. Users should consult their local ordinances to determine if eutylone is a legal drug in their area.

Eutylone is distributed mostly through online channels. It can also be found locally in some areas via individual suppliers and manufacturers. It’s typically inexpensive, regardless of where it is sourced.

Dosage and Administration

Substance use, even with legal drugs like bk-EBDB, should be approached cautiously with an understanding of all risks and benefits involved.

The effects of Eutylone can differ based on:

  • the dosage amount and frequency
  • the user’s health, height, and weight
  • the user’s previous experience with the substance
  • additional substances used at the same time, including prescription medications
  • the method of administration
  • the user’s tolerance of this or similar substances

When administering any substance, use a test kit or strips to ensure the legitimacy of the drug and follow harm reduction protocols like sober supervision for the best outcome.

It’s recommended to start with a small dose initially and then increase the dosage as you become more familiar with the effects and the way your body reacts to bk-EBDB.

10-20mg per 100 lbs. of body weight is a typical dose for administration via the following methods:

Oral Administration

Eutylone can be administered orally in capsule or pill form. It’s also often mixed with a liquid and ingested. Users sometimes recommend wrapping powder or crushed crystals in tissue or cigarette paper and swallowing it in a method called “bombing”.

Nasal Insufflation

Some users prefer to insufflate (also described as “snorting”) bk-EBDB in powder form or by crushing crystals. This often results in a faster onset of effects. This method is often accompanied by a brief but intense burning sensation in the nasal passages.


Bk-EBDB is commonly vaporized or smoked and inhaled using a vaporizer or pipe. It’s not recommended to use cigarette papers as loose powder or crystals are difficult to roll and will melt before they can be inhaled.

Intravenous Administration

Users report success in melting or dissolving eutylone in liquid and administering it intravenously. When administering any substance intravenously, use clean needles and refrain from sharing with other users to prevent the spread of communicable diseases.

Sublingual or Buccal Administration

Eutylone can be dissolved under the tongue or between the gum and cheek to absorb into the bloodstream. Some users dislike this method because of the amount of time it takes to dissolve and the aftertaste. Drinking water after the powder or crushed crystals dissolve to flush any remnants from the mouth is recommended.

Suppository Administration

Some users prefer to encapsulate or dissolve bk-EBDB and insert it into the rectum as an alternative to other means of administration. This method of administration typically doesn’t alter the effects of the substance and often results in a faster onset of effects compared to oral, nasal, or sublingual administration.


Administering subsequent doses to prolong the effects of the substance is common practice with eutylone. If you’re experiencing negative side effects, it’s not recommended to redose. Eutylone may induce a compulsion to redose as a common side effect. When redosing, aim to use an equal or lesser amount than the initial dose until you know how the drug reacts in your system.

User bk-EBDB Reviews

Research chemical reviews are often self-reported and should be taken anecdotally, not as evidence or fact. The timelines and effects mentioned in this eutylone review are an approximation based on the self-reported experience of other users.

Onset of Effects

The effects of eutylone generally begin to kick in within 15-30 minutes of administering the initial dose, depending on the method of administration and the dosage amount. Effects are reported to last between 4-8 hours and aftereffects may be experienced for as long as 24 hours after the offset.

Increased Energy

Users typically report feeling an increase in energy, alertness, and mental stimulation following administration of bk-EBDB, similar to other synthetic cathinones.


Eutylone reportedly induces euphoric feelings that are commonly described by experienced users as mild in comparison to other stimulants and cathinones. This may include feelings of peacefulness, comfort, satisfaction, or a physical manifestation of gentle warmth. It’s also described as an empathogen and reportedly causes a significant increase in the user’s ability to empathize with others.

Increased Libido

Many users report experiencing an increase in their sex drive and sexual attraction towards others as a result of administering bk-EBDB. An increased desire for sexual contact and/or sexual thoughts and feelings are commonly experienced while using this stimulant.

Enhanced Physical Senses

A general increase in physical perceptions of sounds, textures, tastes, and visual sensations is commonly reported as a result of using bk-EBDB. Users may find enhanced immersion in physical experiences like music, art, and tactile stimulation.


The anticlimax experienced as the effects of eutylone wear off is commonly reported to be mild, but results may differ based on the user’s tolerance, the dosage, and other substances taken in combination. It generally sets in within 4-8 hours after the final dose and may include mild to moderate feelings of anxiety, depression or low mood, and physical or mental fatigue.

Potential Side Effects of Eutylone

As with any substance, there are potential side effects of bk-EBDB. Some of the potential side effects include (but aren’t limited to):

  • Insomnia
  • Dizziness & headaches
  • Anxiety
  • Jaw clenching and/or teeth grinding (also known as bruxism)
  • Dehydration
  • Reduced appetite
  • Arrhythmia
  • Sweating
  • Hyperthermia
  • Increased levels of agitation and aggression
  • Nausea
  • Vomiting
  • Hypertension
  • Seizures
  • Hemorrhage
  • Paranoia or psychosis
  • Hallucinations
  • Death

If you experience severe negative effects, contact your local emergency department and let them know the dosage and frequency of eutylone that you have self-administered to prevent reactions with other drugs they may prescribe to prevent further harm.
