Opioids Euphoric analogs of fentanyl?

Okay so as many of you know, the high from fentanyl isn’t known for having a large amount of euphoria. It’s typically hit it, pass out, wake up and hit it, rinse and repeat. It’s usually just sedation and sleepiness with a little euphoria if any. I’ve heard that there are SOME analogs of fentanyl that actually bring some euphoria to table as well as some having a longer half life. Could someone give me some examples of what these analogs would be, whether you have tried them or not?
 
Theyre not nearly as accessible now as they once were but generally the weaker potency ones have been regarded as more euphoric from fentanyl
AcetylFentanyl ~15x Morphine
ButyrFentanyl ~25x Morphine
FuranylFentanyl ~50x Morphine (allegedly)

These used to be the most popular fentalogues on forums regarding euphoria

But while these are more euphoric than fentanyl they are still a far cry from Morphinans which is a much better drug class for recreation. More euphoria, longer duration and better safety profile

Thank you man! I recently got some heroin that was mostly if not all fentanyl that is actually very euphoric and I’m just curious what it is because I’ve had plenty of fentanyl and plenty of “fettydope” and lots of different blues and none of them have been euphoric like this.

I would send it in for testing if I were you, it could be a fentalogue or a nitazene or a mix of zenes/fentalogues + other things

It it lasts longer than regular fent it might be nitazenes

Shoot there are tons of things that could prolong it. I don't know much about Nitazenes but ty for bringing that up, I need to look into those more. I have heard positive things about AcetylFentanyl even though admittedly I do not think I have ever done it and if I had, it was unknowingly. Are there even basic tests for the different analogues? Where I am located, Its mainly xylazine test strips and straight fentanyl test strips. I know you can get them from places like elevation chemicals (I would totally recommend, much cheaper than other places) bunk Police, etc... However these blot test kits to my knowledge do not test for different analogues. So essentially I am wondering how does anyone know if they are given a analogue like Acetylfent in the first place? Be safe / get well mates!

I believe the fent test strips will be positive from some of the analogs but not all if I remember correctly. You wouldn’t definitively know unless you sent it in for testing though. I would actually like to try the different analogs in their isolated form (for science of course)

Yup, that's all we have here in Portland- hit, pass out. I miss the euphoria 😔

Ugh yeah I hate it so much. Once you’ve been a heroin addict only being able to get fentanyl it’s just painful lol

Hopefully a new scaffold will be available as an RC eventually. Something with less potency, more euphoria and longer duration

Altough with all the profit that the chinese are making from fent and zenes I doubt theyd bother researching new structures…

Oh of course I used to do a lot of science experiments. Its always for science. That is a great point to and thanks for educating me on that. I would guess I probably have tried them and not known in the past. I wonder if while making it, they accidentally make a certain analogue instead of straight fent. From what I heard, now with all the cartels going down, its mostly individuals making it in their kitchens and I would assume they are all not Walter White. That would be sweet though. Probably were just taught by someone to make it a certain way and may make different kinds on accident without knowing. I heard they test it on rabbits and if they die its a good batch. I don't know if this is legit and it may be the government or LE trying to scare people or make them look worse but its possible I suppose.
 
No idea if it's euphoric but back in 1981 George Marquardt began distributing α-methyl fentanyl. Now the reasons he went with αMF are (as I understand it):

1-It had been well characaterized by Janssen so the potency, TI, synthesis and duration-of-action were all detailed in academic papers.
2-It was the simplest legal fentanyl homologue.
3-One of the precursors is BMK, the same precursor that is commonly used to synthesize methamphetamine (which GM had previously been caught making)
4-Animal models and human models suggested that αMF has a similar duration of action as heroin, so it was specifically intended to be an 'invisible active cut'

I have no idea if there were other reasons or indeed all of the reasons listed were significant, but they are a matter of record.

Most people fail to note than unlike fentanyl, αMF is chiral and Janssen demonstrated one enantiomer to be more potent than the other (I forget which) but both have TIs higher than fentanyl.

The precursor bit is quite interesting. Also very interesting about a similar duration to heroin. I wonder if I’ve ever had H with aMF in it. Thank you for the info!

Good observation. China, doesn't really innovate much. They just copy it....poorly and charge little for crap. That just seems to be the trend. Copyright laws and patents mean nothing to them. There is some weird shit going on there now, for some reason.

Well, if you were using H in the early 1980s in the US - possibly.

It's a classic example of Grisham's law. Someone in the American Midwest decided for whateever reasons that selling αMF cut in an evidently inexert manner was a good idea. Suddently a bunch of people were found dead with all the classic symptoms of a heroin overdose but with no heroin or indeed apparently ANY drug in their bodies.

I believe the DEA couldn't identify αMF from post mortem samples but found an unconsumed sample... which they misidentified(?) as 3-methyl fentanyl. But they saw how many fentanyl homologues were possible and instead of attempting to control each one individually, they instead deveoped the CSA laws. I think they did issue temporary control on a few homologues to get the chemist in the meantime.

But that's why the CSA law was introduced. Yes, MPPP homologues had turned up earlier as pseudolegal compounds, there were few enough to control explicitly.
