Phenethylamines The Small & Handy 2C-EF Thread

I have some 2c-ef coming soon, but was wondering about dosages. So far, I've seen reports that it's similar to 2c-e with regard to dosage, but I wanted to see if anyone could confirm that, especially for powder and not the pressed pills. I'm a bit of a hard head, so my 2c-e doses are a bit on the heavy end (around 25-30 mg). I'm thinking about starting with a 20 mg dose and seeing how it goes, but I'd rather not have an underwhelming experience. I guess I could always supplement with some insufflated 2c-b, but for the first time, I usually like to have a "pure" experience.
 
Had a very chill and relaxed afternoon on 5mg 2c-ef. It took quite a while to come up.

There was already some body load but nothing too distracting.

Solid +2

I think 7.5mg will be plenty for me next time.
 
Oral. Half a 10mg blue pellet.
I suspect these are from Lizard Labs originally.

If the contents of the scored blue presses are 2C-EF *and* if all of the circulating scored blue presses contain the same material, then they may a little erratic in how they're dosed based on reports I've been reading. Doses seem all over the place, with some people thinking that a half tablet is plenty, while others think 4x as much is dull.

That said, it's a phenethylamine (which can be underwhelming for people that aren't familiar with them) and it's a 2C-x (which can have wildly variable dose-response relationships anyway. I hate presses, because we're unlike to ever know dosages unless someone sends off several for quantitative analysis.

F&B may think that, I think differently. For a full on experience I'd begin at 15 & work up as you get a feel for the material.

Although I wouldn't trust the pressies either, it may be 2C-EF's fault.
 
Here’s my experience with 2C-EF (powder).

This took place in November of 2024.

obtained 100mg 2C-EF, no food in over 5-6 hours, no other psychoactive compounds actively in my system, at home.
it’s white powder with the consistency of flour.
+0 (445pm): dosed 16mg of powder orally with some water.
+15min (5pm): waiting for the come up. not worried bout anything, tried to put any expectations aside in order to try and give a honest report. In a controlled setting with various entertainment.

+1hr (545pm): body feels heavy and light ? it has that “lightness” feeling of something like 2c-B, but still also feels heavy; “deep?”. I’m a bit cold, I’m normal to being cold but there’s vasoconstriction for sure. Safe to say I’m atleast on the come up somewhere at this point. light trails, some things are more defined (patterns, colors, etc.), pop out , slight vibration. Nothing OEV that really makes me say woah yet, it still has time. I didn’t want to dose it too deeply as I have some responsibilities still upcoming.

+1:40 still typing. the visual effects I described are ramping up. Still heavy. Bright room lights are much more intense than normally perceived, some patterns and some objects are breathing and moving slightly. Some slight and general shifting, moving, vibrations, breathing: especially when fixated, some objects and patterns make this effect more pronounced. However you want to classify that. My bodies thermoregulation is defenitely off, so if that’s something that makes you uncomfortable maybe have a supplement? It has the effect profile of some its related 2c-x compounds: just a decent amount of pronounced vasoconstriction, a deeper body load (in say comparison 2cb). Im sure of course different doses will give you a different outcome or intensity of effects.
I’m going to take a break from reporting.

+2:30. Body load has set in mostly. Visuals are much more in depth , things are much more animated in nature.

+3:33 , everything continued from before but amplified . I don’t want to draw comparisons or be quick to, but for the sake of typing on a peak and not having any better description of what I’m currently going through at 16-17mg orally….. in regards to body load or the physical effect, it’s not something as “light” as classic pure 2cb per say, or as light as regular psilocybin. the body load feels deeper and more ingrained, closer to a 2ce, BUT it is still unique in its own way. What’s in my field of vision is distorting, drifting, vibrating, patterns and textures flow. There’s a general animation to a lot of things; most ridged shapes and text still keep their defining lines yet still somewhat meshing.

*All the physical and visual effects from the onset into the peak (& during) ramping up alongside one another, was like 2 symphonies or 2 orchestras harmonizing and gradually coming to a crescendo cohesively*
4hr:37min… continued from 3:33 mostly. But I think I had experienced the brunt or most of the immediate peak? Like to say I’m “mid journey”. what’s happening now is mostly what I described previous but the physical load of have become more “drawn out”, not as acutely intense but still there.

+7hr30min the most intense of the visual effects and aspects mostly OEV have mellowed along with the body high, but it’s still very much apparent and there and cohesive.

EDIT(S): +8hrs in, in retrospect maybe 16mg oral was a good spot to really experience the compound and what it has to offer in doses in the similar range or what can be explored even higher, especially with the limited amount I have.

+10hr:31min, safe to say have come down a decent amount. But it really slapped me around, especially the body load being on the heavier side and OEVs rich at this dose, (if you really want a comparison) it was more akin to like 2ce/2ci/2cb. I’d say come up was upward of 90 minute range possibly give or take. It really REALLY started to take off 2hr-2:30 in and built on from there.
This is my only experience with it, I still have some left, so I’ll explore it again sometime probably.

: extra notes and thoughts : I still very much so had laughter and smiling at the slightest things especially coming up, but did get locked in a serious headspace (also considering my environment.) there’s some calm before the very lovely storm.. overall I didn’t have much nausea on an empty stomach. When shulgin was confident enough to not even have synthed it and predicted it to be good, well he was right. How good? That’s in the eye of the beholder and subjective to everyone as more reports roll in with this now that this batch has been confirmed to be 2c-ef and not a mix of 2cx compounds labeled as. 2c-ef. I don’t want to draw toooooo many comparisons to avoid clouding others judgement and expectations of those waiting to use it, really only to be used as a relatively vague reference point for safety for anyone wanting to try it.

I was on the fence about grabbing this one, but seeing how I’ve done most of the 2c-x compounds, I had to give it a shot. I ordered 500mg of 2c-I, 50 tabs of lsd, 1g 3-meo-pce, 1g of MDA, and then added a 50mg 2c-ef sample. It was supposed to arrive today, but USPS is in the business of killing hopes and dreams. That said, this is going to be a killer pack. Thinking ima go hard and combine MDA, 2c-I, lsd, and 3-meo-pce for first run then try the 2c-ef on its own to get a feel for its own effects.
 
2c-ef is much more powerful to me than 2c-e in similar doses. I tried out 28 mgs of 2c-ef, thinking it'd be slightly weaker, but longer lasting than the same dose of 2c-e. Ho boy, was I wrong. It's stronger and lasts around 12 or so hours (whereas 2c-e is around 8 for me). It's got an awesome bodyfeel, not as visual as some other 2cs (but still plenty visual), and stimmy (but not in a need to move around kinda way). I wrote a quick report about it here:

 
We (2 people) tried 10mg 2C-EF orally in nature two days ago.
I weighed out 40mg NL powder & dissolved it in 2ml rum. Then took 0.5ml each, on an empty stomach.

I noticed first alerts of a bodyload 45min in & was up to a +2 1.5h in. My hand started morphing by that time & the bodyload was quite intense, although very pleasent. No nausea.
We were still kinda coming up 3h in, then inhaled two N2O balloons, which catapulted us to the plateau we stayed on for the next ~6-7h.

It was pretty body heavy, very funny, the visuals were mostly big picture kinda things, f.e. the leaves of a tree were connected by an energy field.

10mg orally is a good dose.

We started coming down about 9-10h in & still were at a +1 12h after ingestion.
We couldn't really sleep till 7 AM (16h after ingestion).
At 6 we snorted 2 ket lines. I didn't feel much from them. Was still able to speak clearly & think coherently.
My trip partner was pretty heavily ketaminated by them (she has the same low disso tolerance I have & we took the same ket dose).

This is the second time I didn't feel the ket when snorted on the comedown of a psychedelic. I don't know what's going on there.

I'll write a longer trip report about this experience. Just wanted to share the basic facts.

Next time, we'll take 5-6mg rectally.

My first trip on 2c-ef 10mg


The onset of the drug is comforting and slow. I feel very positive and my libido is healthy again I’m finding joy in porn again after a hard breakup.

It has a tinge of MDMA style trauma comfort I feel like I’m very okay with how my breakup went even though I know we both have our own lives and sides of the story. But it also feels softer in a more kind of ‘’Pregabalin’’ way where I’m just also physically comforted and just the slightest mentally numb to the fact.

It is helping me live out my own story and it does have visuals for sure. Already at 5mg I noticed a surprising amount of geometry for the dose and pattern recognition, but it was slow in the beginning but ramped up pretty quick.



It does have a propensity towards horniness just like 2c-b sexuality and the human body and connection seems a keen interest right now, but I am yet to uncover the full potential of this psychedelic trip.

I sometimes resent Alexander Shulgin for shunning dissociatives so hard, they seem to pair perfectly with his favorite inventions. As someone who is a chronic dissociative user I have a feeling of bread and butter combining psychedelics/phenethylamines with dissociatives. He really should’ve explored their connection more and I think that how they’re being explored singularly for therapy now they might actually work better in tandem in the future. But that has yet the potential to be seen. Now to continue his grace would be to find of course the perfect cocktail of incredibly helpful and beneficial psychoactive substances to treat the mind and rid it of depression and trauma. But that has also yet to develop as we rush towards it together in a race to the finish line.

The visuals remind me more of a painting and less mayan, Aztec, Greek, roman, African stuff going on than on the usual psychedelic like LSD but this seems like the world is just flowing and falling in place just correctly and like it should be and that things have a time and purpose in the given space of mind.



It kind of scares me because it feels like I got over the trauma in 1 day. It seems like yesterdays news, everything that’s been heaping on my mind and tormenting me the whole time since I just broke up. I don’t know how ill reflect on it tomorrow, but I can only say that I do remember memories fondly and that life is a pleasure. Things are going to be okay and it doesn’t matter if I tripped on a banana peel and potentially died. It has that kinda MDMA styled cure potential. And its ironic im mentioning banana’s because I used to call my last partner Banana but I am indeed on a psychedelic trip. And I have banana’s in my fridge. The generality and synchronicity of it all is totally banana’s.

This trip in general is really personal and feels like it gives a vibe of a lot of character development. I am adding additional harder songs to sing to my repertoire, and it all seems to be adjusting to the timeline of events that went down in my life. Things are clicking easier or so it seems to me.

Im relistening to old classics and vetting material and I feel happy and forward looking to the next day, which is always an important factor in my world of depression. I definitely feel a strong will to perservere on this substance and I’m drawing every last push from it to do so.
 
2C-EF (my second time taking it)

My second trip on this substance was on 10mg in a form of a pill I received from a vendor I frequent. This was nothing short of delightful, it really acts like a small candyflip dosage and seems to help with dealing with heavy trauma. As previously described I am currently in the middle of a hard time and a heavy breakup and after taking this substance my woes just seemed to fade away very quickly, just like it’s described in literature with MDMA I have confronted my demons very honestly and quickly and I feel at peace and looking forward to life but it also has the psychedelic edge of making me enjoy what’s to come at the same time.

At one point I was just fiddling with my spiderman and shrooms keychains for a good 5 or 10 minutes or so while sitting on a chair in the lawn, the sun was shining bright and the birds were singing and the plants looked beautiful as did the grass. The dissos I already take seem to offset and combine perfectly with every psychedelic in the manner that makes a bad trip seem impossible but shall it happen beneficial at worst and that’s kind of a best.

I took a long walk and enjoyed watching my favorite twitch streamers again and my libido seems to be healthy and back again after an almost scarily loss of interest in sex after I broke up with my last partner of almost a year. That was a nice thing to experience from this compound as heartbreak can often mess one up more than any drug or tragedy could. And I speak from many experiences saying this.

Somehow this drug just induces the feeling of everything being okay better than MDMA as it isn’t incredibly physiologically overwhelming in its effects as MDMA is stimulative. This just feels like bread and butter and its definitely more on the butter side if you might catch my drift. And the potential knowledge in it’s correlation to 2CB inclines that its far less neurotoxic than MDMA and that just makes the trip a smoother and more pleasurable ride with endless possibilities on the horizon. In all words life is good right now.

It seems to last around 10-12 hours like LSD while the effects aren’t as strong as either MDMA nor LSD but they definitely do feel familiar to them. In any case the peak of effects shouldn’t be expected as crazy in intensity but rather a smooth plane ride from Stockholm to Brazil that lasts around 10-16 hours where you will feel frankly zen and relaxed and it does quiet down internal chatter a lot. For me it included an afterglow the day after I woke up and while I definitely didn’t feel it much anymore when I went to bed, you do still kinda feel the general exploratory character development effects of the trip you’ve just been on.

Nature is really nice on it I recommend taking it outside in the sun or in the dark however you feel most comfortable. You should do it in a comfortable set and setting like any psychedelic to ensure a good time, but taking this one in an uncomfortable setting could lead to tricky business so ensure you always feel well and relaxed before taking this psychedelic and otherwise just enjoy the ride.

If this drug was an athlete it’d definitely be an endurance athlete

I definitely understand why he & Ann weren't fans of dissociatives.
They were always looking for the drugs that promote communication, sexual connection & clear-headedness. Dissociatives do the exact opposite most of the time.

Combining ketamine with psychedelics never worked for me.
The psychedelic seems to overpower the ket almost completely. I only tried snorting it after the peak.

N2O on the other hand works great in all stages of the psychedelic experience.
Very strange.

But I do agree the combination has potential.

And an AiHKAL would have been awesome.
But hey, we got @Nervewing !
 
Eventually got around to trying 2C-EF, many years after my initial encounter (at 15mg dose). It is an utter delight to be reacquainted with and reinforced everything I initially said about it. I would also add, that it is probably the most friendly phenethylamine I've ever encountered - even more so than 2C-C or 2C-T-21 (2-fluoroethyl is a psuedohalogen group) and one I'm heartily recommend as a 1st phenethylamine (comparable with AL-LAD & 4-hydroxy DET for its lack of 'headfuck'). My friend tried 25mg and was of the same opinion. It is good natured and a source of endless laughing fits. Really, it's a shame it took so long for it to be widely available...

One more thing, it's duration was in the range of 6-8 hours (I don't know if people experiencing a duration comparable with LSD had either taken a much larger dose, or had it in combination with other psychoactives)

I've been majorly slacking, but I finally wrote up two reports for 2C-EF rectally. There's nothing really revelatory there - the trips sound consistent with the ones above, but the duration is shorter and I assume it's twice as potent. Very nice stuff, and probably my favorite non-thio 2C-x. I'd like to try insufflating it, but I probably won't because I've only got tablets and that makes dosing a pain.
