Eutyloneβ-Keto-1,3-benzodioxolyl-N-ethylbutanamine ('Eutylone, bk-EBDB, N-Ethylbutylone) is a stimulant compound developed in the 1960s which has been reported as a novel designer drug and has appeared recently (2019) being sold as a designer drug.
As a designer drug, it is commonly sold on the street along with ethylone as a substitute or counterfeit for NEP and methylone (all of which have collectively come to be referred to as "stimulating with low serotonergic activity") due to methylone's declining availability on the research chemical market. However, in spite of behavioral and pharmacological similarities between eutylone and MDMA, the observed subjective effects of both substances are not completely identical, eutylone has some of the euphoria which can remind of that of MDMA, but with a shorter duration and weaker effects. . _Ask_Dr._Shulgin_Online-1|[1]
Euthylone has an extremely short history of human use and very little data exists about its pharmacological properties, metabolism, and toxicity. It is highly advised to use harm reduction practices if using this substance.
Eutylone or β-Keto-1,3-benzodioxolyl-N-ethylbutanamine , is a synthetic molecule of the cathinone family. Cathinones are structurally similar to amphetamines in that they contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional ethyl substitution at Rα. Cathinones such as eutylone are alpha-methylated phenethylamines (i.e. amphetamines) but differ from them with the addition of a ketone functional group (a carbonyl group at Rβ).
Pharmacology
Eutylone acts as a mixed reuptake inhibitor/releasing agent of serotonin, norepinephrine, and dopamine.[2][3] These are the neurotransmitters in charge of pleasure, reward, motivation and focus. This is done by inhibiting the reuptake and reabsorption of the neurotransmitters after they have performed their function of transmitting a neural impulse, essentially allowing them to accumulate and be reused, causing physically stimulating and euphoric effects.
In comparison to methylone, it has much lower affinity for the norepinephrine transporter, while its affinity for the serotonin and dopamine transporters is similar.[4][5] The results of these differences in pharmacology relative to MDMA is that butylone, like its close analog ethylone is less potent in terms of dose, has more balanced catecholaminergic effects relative to serotonergic, and behaves more like a reuptake inhibitor like methylphenidate than a releaser like amphetamine; however, eutyulonestill has relatively robust releasing capabilities.[6]
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 PsychonautWikicontributors. As a result, they should be viewed with a healthy degree of skepticism.
It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.
Physical effects
Stimulation - In terms of its effects on the user's physical energy levels, eutyulone is commonly considered to be highly stimulating and energetic. This encourages activities such as running, climbing and dancing in a way that makes eutyulone a popular choice for musical events such as festivals and raves. The particular style of stimulation which eutyulone presents can be described as forced. This means that at higher doses, it becomes difficult or impossible to keep still as jaw clenching, involuntarily bodily shakes, and vibrations become present, resulting in an extreme unsteadiness of the hands and a general lack of motor control.
Spontaneous physical sensations - The "body high" of eutyulone can be described as a strong euphoric tingling sensation that encompasses the entire body. It is capable of becoming overwhelmingly pleasurable at higher doses. This sensation maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached.
Vibrating vision - At high doses, a person's eyeballs may begin to spontaneously wiggle back and forth in a rapid motion, causing the vision to become blurry and temporarily out of focus. This is a condition known as nystagmus.
Dehydration - Feelings of dry mouth and dehydration are a universal experience with eutyulone ; this effect is a product of an increased heart rate and an extreme motivation to engage in strenuous physical activities. While it is important to avoid becoming dehydrated (especially when out dancing in a hot environment) there have been some users suffering from water intoxication through over-drinking, so it is advised that users simply sip at water and never over-drink.
Difficulty urinating - Higher doses of eutyulone result in an overall difficulty when it comes to urination. This is an effect that is entirely temporary and harmless. It is due to eutyulone's promotion of the release of anti-diuretic hormone (ADH). ADH is responsible for regulating urination. This effect can be lessened by simply relaxing, but can be significantly relieved by placing a hot flannel over the genitals to warm them up and encourage blood flow.
Teeth grinding - This component can be considered to be less intense when compared with that of MDMA.
Cognitive effects
The cognitive effects of eutyulone can be broken down into several components which progressively intensify proportional to dosage. The general headspace of eutyulone is described by many as one of extreme mental stimulation, light feelings of love or empathy and moderate euphoria. It contains a large number of typical psychedelic, entactogenic and stimulant cognitive effects.
The most prominent of these cognitive effects include:
Cognitive euphoria - Strong emotional euphoria and feelings of happiness are present within eutyulone and are likely a direct result of serotonin and dopamine release. In comparison to MDMA, it is closer in effects to that of the euphoria felt within amphetamine and mephedrone.
Empathy, love, and sociability enhancement - Although distinct and powerful in its effects, this particular feeling is less pronounced and therapeutic when compared to that of MDMA. It can be described as less forceful and more internal in its manifestation, resulting in feelings of love and empathy that are not necessarily felt as essential to express to others.
Time distortion - Strong feelings of time compression are common within eutyulone and speed up the experience of time quite noticeably.
The effects which occur during the offset of a stimulant experience generally feel negative and uncomfortable in comparison to the effects which occurred during its peak. This is often referred to as a "comedown" and occurs because of neurotransmitter depletion. Its effects commonly include:
There are currently no anecdotal reports which describe the effects of this compound within our experience index. Additional experience reports can be found on the subreddit /r/researchchemicals
The toxicity and long-term health effects of recreational Eutylone use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because Eutylone has very little history of human usage. Anecdotal evidence from people who have tried Eutylone within the community suggests that there do not seem to be strong adverse effects attributed to using this substance at low to moderate doses and sparingly.
As with other stimulants, the chronic use of Eutylone can be considered moderately addictive with a high potential for abuse and is capable of causing psychological dependence among certain users. When addiction has developed, cravings and withdrawal effects may occur if a person suddenly stops their usage.
Tolerance to many of the effects of eutyulone develops with prolonged and repeated use. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about 3 - 7 days for the tolerance to be reduced to half and 1 - 2 weeks to be back at baseline (in the absence of further consumption). Eutyulone presents cross-tolerance with [[Cross-tolerance::all dopaminergicstimulants]], meaning that after the consumption of Eutyulone all stimulants will have a reduced effect.
Abuse of compounds within the stimulant class at high dosages for prolonged periods of time can potentially result in a stimulant psychosis that may present with a variety of symptoms (e.g., paranoia, hallucinations, or delusions).[7] A review on treatment for amphetamine, dextroamphetamine, and methamphetamine abuse-induced psychosis states that about 5–15% of users fail to recover completely.[8][9] The same review asserts that, based upon at least one trial, antipsychotic medications effectively resolve the symptoms of acute amphetamine psychosis.[10] Psychosis very rarely arises from therapeutic use.[11][12]
Dangerous interactions
Warning:Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).
Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.
]] & ]] - 25x compounds are highly stimulating and physically straining. Combinations with Eutylone should be strictly avoided due to the risk of excessive stimulation and heart strain. This can result in increased blood pressure, vasoconstriction, panic attacks, thought loops, seizures, and heart failure in extreme cases.
]] - Combining alcohol with stimulants can be dangerous due to the risk of accidental over-intoxication. Stimulants mask alcohol's depressant effects, which is what most people use to assess their degree of intoxication. Once the stimulant wears off, the depressant effects will be left unopposed, which can result in blackouts and severe respiratory depression. If mixing, the user should strictly limit themselves to only drinking a certain amount of alcohol per hour.
]] - Combinations with DXM should be avoided due to its inhibiting effects on serotonin and norepinephrine reuptake. There is an increased risk of panic attacks and hypertensive crisis, or serotonin syndrome with serotonin releasers (MDMA, methylone, mephedrone, etc.). Monitor blood pressure carefully and avoid strenuous physical activity.
]] - Any neurotoxic effects of MDMA are likely to be increased when other stimulants are present. There is also a risk of excessive blood pressure and heart strain (cardiotoxicity).
]] - Some reports suggest combinations with MXE may dangerously increase blood pressure and increase the risk of mania and psychosis.
]] - Both classes carry a risk of delusions, mania and psychosis, and these risk may be multiplied when combined.
Combinations with the following substances can cause dangerously high serotonin levels. Serotonin syndrome requires immediate medical attention and can be fatal if left untreated.
