250 mg 3,4-EtMC (Male, ca. 90 kg)

I did not find any specific reports or dosing recommendations online so I figured to take the dosages on psychonautwiki for [methylone](https://psychonautwiki.org/wiki/Methylone) (oral) as a rough estimate, which sets a "common" dose around 150 to 225 mg.

I seem to be somewhat sensitive to MDMA and 80-100 mg is enough for me, maybe 40-50 mg around at T+2.5-3 h would be a commond dosing regimen for MDMA for me.

Empty stomach (only some blueberries, lunch was T-6), had coffee+ritalin around T-10 and another coffee around T-4.

19:15 100 mg dissolved in water, common PEA taste, lightly numbing the mouth, quickly had an uncomfortable feeling in the stomach like I drank too fast or went without food for way too long. But I also noted that my stomach felt full.

T+1 (20:13)

Fast comeup, cigs taste amazing, very talkative and electric, good at listening and connecting the dots of a conversation as well as keeping everyone included (discussions had 3-5 participants). In the bathroom feeling somewhat shaky, like the effects are wearing off. Not dissimilar to MDMA but less entactogenic for sure.

4.5 mg 3-MeO-PCE dissolved in water

T+2 (21:21)

Effects quite mellow but feeling elated and generally stimulated / sociable.

50 mg half snorted, half dissolved into water. Light on the nose (don't know what salt, guessing HCl) but lingering menthol-like (or pseudoephedrine like?) nasal feeling (decongested).

T+2.5 (21:46)

noted that this time the effect was not as strong.

4.5 mg 3-MeO-PCE dissolved in water

Ate some tiramisu and half a magherita.

T+4.5 (23:49)

Noted that the substance seems very short acting and that I was reluctant to take any more.

T+5 (0:20)

Decided to take another 100 mg, again a bit nasally and the rest inside a MEDIKINET gelatine capsule.

T+8 (3:17)

Still noticeable stimulant effect and not at baseline.

Had some dry breze.

T+9.5 (4:43)

When I closed my eyes and tried to sleep I got monochrome visual dream images instantly, faces blabbering syllables at me, which I decided where bavarian advertisements.

Notes: I often had very intense movie-like closed eye visuals on the comedown of a night out on MDMA but these were usually highly realistic (visually) and colorful but absurd in the narrative or plot. I usually don't dream in color and do not generally have the capacity to imagine things visually. 3-MeO-PCE, however has reliably allowed me to imagine things more visually and in color, too.

Next Day: slept around 5 hours, had some food, watched a movie, slept another 3 hours. Not noticing any deficits beside sleep deprivation and feeling generally motivated and mentally able. Had some calls and went to buy groceries, no social anxiety. Had some caffeine and MPH and am confident to be able to study.
 
So is this 3.4-Ethylene-Dioxy-Methyl-Cathinone. Or 3.4-Ethylene-Meth-Cathinone which it could also suggest ?

Nice report love that class. Methylone or Ethylone. Last 3.4-Methylene-Dioxy-Ethyl-Cathinone being the lighter version of the two. Both very nice. Never even heard of the Amphetamine version 3.4-EDMA :unsure:

Interesting. The compound is generally referred to as EDMC btw. Based on EDMA compared to MDMA, your experience sounds about right.

So this compound is beta-keto-EDMA pretty much?

Also @drug-nerd , did you test it without also administering anything else? The report is fantastic but when working with novel compounds, using them in mixes can kind of cloud up the perception of them.
