Talk:Eutylone

Eutylone is a synthetic substance 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 R_α. 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 R_β).

Eutylone acts as a mixed reuptake inhibitor and releasing agent of serotonin, norepinephrine, and dopamine.^[2][3] Eutylone modulates theseneurotransmitters in charge of pleasure, reward, motivation and focus. This is done by inhibiting the reuptake and reabsorption of the neurotransmitters back into the cell 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] Despite this lower affinity, eutylone is a stronger reuptake inhibitor than MDMA, although it is less potent and has a more balanced catecholaminergic profile. As a mixed releaser and reuptake inhibitor, it also has relatively robust releasing capabilities.^[6]

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 PsychonautWiki contributors. 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 ☠.

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.

It is strongly recommended that one use harm reduction practices when using this substance.

Tolerance and addiction potential

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 eutylone 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). Eutylone presents cross-tolerance with all dopaminergic stimulants, meaning that after the consumption of Eutylone all stimulants will have a reduced effect.

Psychosis

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-NBOMe & 25x-NBOH - 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.
• Alcohol - 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.
• DXM - 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.
• MDMA - 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).
• MXE - Some reports suggest combinations with MXE may dangerously increase blood pressure and increase the risk of mania and psychosis.
• Dissociatives - Both classes carry a risk of delusions, mania and psychosis, and these risk may be multiplied when combined.
• Stimulants - Eutylone may be dangerous to combine with other stimulants like cocaine as they can increase one's heart rate and blood pressure to dangerous levels.
• Tramadol - Tramadol is known to lower the seizure threshold^[13] and combinations with stimulants may further increase this risk.

Serotonin syndrome risk

Combinations with the following substances can cause dangerously high serotonin levels. Serotonin syndrome requires immediate medical attention and can be fatal if left untreated.

• MAOIs - Such as banisteriopsis caapi, syrian rue, phenelzine, selegiline, and moclobemide.^[14]
• Serotonin releasers - Such as MDMA, 4-FA, methamphetamine, methylone and αMT.
• SSRIs - Such as citalopram and sertraline
• SNRIs - Such as tramadol and venlafaxine
• 5-HTP

• Responsible use
• Entactogens
