Summary dose.wiki TripSit PsychonautWiki

3,4-methylenedioxy-N-ethylcathinone (also known as Ethylone, MDEC and βk-MDEA) is a synthetic entactogen and stimulant of the cathinone class. It is the β-keto analog of MDEA ("Eve"). As a designer drug, ethylone is commonly sold on the street along with other cathinones like butylone or 3-MMC as a substitute or counterfeit for MDMA and/or methylone due to methylone's declining availability on the research chemicals market.

Effects Erowid

Aggregated from 11 single-substance Erowid experience reports; 2 Erowid reports where another drug was taken too are left out

Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

Too few reports for bars: these effects come from 11 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Erowid 8 reports 2 positive 3 neutral 3 cautionary visit

Finishing Off the Bag cautionary exp #100879

Ethylone, it was not my choice to get this. It was alright maybe but for what I wanted (a recreational substance) it was not very. I got slight stimulation and increased interest, dilated pupils which did not correlate at all with the level of intoxication I was feeling.

A Bit Disappointing neutral exp #93560

This was my first experience with ethylone. I have not used any other MDxx drugs before. I was visiting my friend, T, for a night of smoking weed and watching football with a few other friends. Shortly before midnight, T suggested that we do some ethylone, also known as bk-MDEA.

Not Without Use... neutral exp #105468

Dose: t+0.00 100mg ethylone t+2.45 60mg t+3.45 25mg t+4.45 25mg t+6.00 40mg ketamine After two chance encounters with empathogenic substances this past summer, 1 80mg MDMA experience and another unidentified substance/mix, I was amazed and exalted at the human condition when I'm tripping on my own major endogenous psyc...

Subtle and Pleasant positive exp #94687

Im a freshman in college with a pretty decent amount of experience with psychedelics and expanding experience with empatheogens. I did 6-APB around 3 weeks ago, 4-FA about a week and a half before that, and Adderall a week before that so there might be some slight tolerance.

A Subtle Empathogen neutral exp #44573

Here are a few notes, as well as after-the-fact commentary on my experience with ethylone last night: T+0:00 Ingested 200mg ethylone at about 11:32. This dosage was chosen based on a first-hand report from a trusted source.

Fake MDMA Followed by Panic Attacks cautionary exp #105421

I took some of, what I thought was MDMA, at a party, being quite merry at the moment I made the decision to add some excitement to the evening. The substance was sold as MDMA and looked as two large lumps of brownish crystal.

This Is Not Your Mother's Methylone positive exp #49303

Saturday, 8:00PM T+00:00 80mg of BK-MDEA (ethylone) down the hatch, gel cap, light meal two hours before. only water since. T+00:08 get the methylone belch, similar taste T+00:27 the belch again, first alert, feeling 'light' T+00:38 rushing, antsy, walk from room to room.

Good High Bad Comedown cautionary exp #104007

Better Than Others Say / Good High Bad Comedown About 7 of the ten reports I've found on this stuff says it was a big disappointment, no euphoria, only slight head high, and not worth it at all. And the other three said that it was only decent, nowhere close to Molly.
