There is a fentanyl analogue that is available and ULTRA SUPER CHEAP per dose, because the dose is 5-10 micrograms of the pure powder and it can be bought by the gram. It's called carfentanyl, and people report that it lasts for like 8 hours and is extremely euphoric, and not much like fentanyl at all.

I've had pharma fentanyl, found it really boring, just a heavy stoning/sedation, I had to sit down, then lay down, my body felt good but I did not have an elevated mood at all.

I've had real heroin 99% purity from Pakistan, my group had it lab analyzed and it checked out. This was on a secret forum of ~30 members who did group buys and where some people had some really serious connection. Shit was light tan and smelled of vinegar. 7-10mg snorted would have me nodding in and out of the most amazing dreams for hours... I felt so damn good, it was insane. If that was a 10, fentanyl was a 1.5, in terms of euphoria.
I can't see normal street dealers having access to or even daring to associate with carfent. I could be totally wrong on this! I just suspect that on the East Coast (at least) there is an altered fent that is more euphoric and with a longer duration of effects that is not carfent. I suppose it is definitely possible for counterfeit pills that feel "heavenly" to be comprised of an incredibly small insignificant dose of carfent. I'm still trying to figure it out to be honest lol. It was too euphoric to be oxy and the pills were measured accurately down to a wire. To this day I consider those fake blue roxies and endocets to be the best feeling I've ever known. They delivered pure euphoria, itching, nodding--but were also strangely energizing like adderall. It's what I imagine good heroin to feel like.. such an amazing sensation it's the only thing you want to do 24/7. They're not around anymore but when the quarantine started they thrived because oxycodone medications were being stripped away from patients to keep it off the streets (with unfortunate consequences for chronic pain patients on the flip side :().

It may interest some to know that the "duration of action" is a different thing altogether to the elimination half life of a drug (although they are to a degree linked). Also interesting to note that the elimination half life of a drug differs depending on the route of administration (believe it or not)
Wow that is interesting. Can you expound?

Well there’s the issue right there, many of us aren’t talking about tar which is garbage in comparison to high purity diacetylmorphine.

But then real high purity heroin is but a legend at this point, the only scene in the US not completely taken over by fentanyl is the SW Tar scene.

Ah, well that may well be. But as you say, who’s getting that pure afghan shit anymore anyway? Also, all those years at the methadone clinic they used to test us once a month. It would always come back positive for either codein, oxycodone, or morphine. Or a combination of the 3. But there were several times (in nearly 20 years) where my counselor showed me that it actually came back positive for “heroin”, meaning it was the real deal. But again, when you’re a high tolerance methadone/heroin user, you can kiss the euphoria goodbye. It’s only the blue fent pills that have been scratching that itch for me (and just barely at that).

Morning.


I had to check these dates of these posts twice to ensure I wasn't looking at a corpse thread or something posted like decades ago and I missed it. And far be it for me correct information furnished by a moderator who has been around for over a decade. But in this particular case I think it warranted. And I suppose in fairness: we all have our own drugs interests and therefore will have spent more time researching a particular drug over another e.g. don't ask me anything about meth. because I wouldn't have the answer given that its interest to me is limited purely to the commercial value.

The above all being said: I'm posting this in the true spirit of harm reduction i.e. lest some new user or guest browsing comes across this information and goes on a quest to obtain Carfentanil (sometimes spelled Carfentanyl) assuming it to be the shit based on the information contained on this thread.

Although the generally quoted figures vary some (usually not by much though): Carfentanil is 100 times stronger than Fentanyl, 5 000 times stronger than Herion, and a heroic 10 000 times stronger than Morphine. It was first synthesized in 1974 and became commercially available in 1986 being sold as an anesthetic for veterinary use (to anaesthetize large mammals e.g. elephant and rhino to name but two). It has further been weaponized i.e. used by the Russians in 2002 during the Moscow theater hostage crisis. It only became a controlled substance in China in 2017 (but of course not to be outdone and in true Chinese fashion is still being manufactured and can still be purchased the caveat, as usual, being the purported purity of the powder available).

I'm not going to re-type the entire Internet here. But the above should give you a rough idea as to why it's probably not a good idea to source and use.

One or two anecdotes:

Yip. It would be measured in µg (micrograms). Given that I know personally what 16.8µg of Fentanyl looks like (almost imperceptible) well then I don't know how you'd calculate a dose save for making a measured solution in order to calculate the per ml concentration.

The generally accepted lethal dose of Fentanyl for an average human being is 2mg. Based on this: you do the math (as to what the possible lethal dose of Carfentanil could be) (although if it's any consolation it's, oddly enough, less deadly in rats than Fentanyl itself and for a variety of reasons but which I doubt are applicable here).

It may interest some to know that the "duration of action" is a different thing altogether to the elimination half life of a drug (although they are to a degree linked). Also interesting to note that the elimination half life of a drug differs depending on the route of administration (believe it or not).

Anybody wanting to put this to the test: may as well go for broke then i.e. Ohmefentanyl anyone? Lol!

Edit:

For the sake of interest and as usual trying to do a thorough job of things see the document below. Sadly it's dated (2017) but is a report from the WHO re: Carfentanil. Pretty much everything you want to know really all nicely summed up (and some interesting factoids that even I was not aware of until now).

Carfentanil - Critical Review Report
I think the confusion about when carfentinil was approved is it was recently approved for humans in a combat setting. The judge said he was inclined to approve it despite the risks for soldiers whose injuries made getting into a vein impossible, it’s strong enough to take it as a sublingual in the field.

That's interesting. Now that I did NOT know. As a matter of interest: do you know if it was approved to be used in a diluted form or meant to "end suffering permanently" (trying not to be gross about it hence my choice of words)?

Sorry. Just asking. As a few around here may know: I have a sort of "anything Fentanyl related fetish" so have a never ending thirst for knowledge on the topic (and I cannot really even give you a good reason for this i.e. I'm not even a user) (says he while slowly building up a stash of pharmaceutical Fentanyl freebase! Lol!).

I started a thread on this very topic some time ago. Lemme get the link and I'll post it here for reference with some additional information.

As promised above:


Off topic of this thread? Not sure. Not the end of the world if it is though.

Anyway. Here's more (once again saves me from re-typing the entire content of the Internet).

Biological Half Life

There's various links in the page linking to different half lives.

As for the different ROA's resulting in different elimination half lives then take a look at the table on the far right of the document below under the main heading "Pharmacokinetic data" and the sub heading "Elimination half-life" (but this in relation to Fentanyl not Carfentanil) (the latter, for the sake of interest, having an elimination half-life of 7.7 hours and in the case of Carfentanil I'd make the assumption that this is based on the ROA being IV and nothing else).


Just some useful (useless?) information for possible future reference (fill up some empty brain cells for the hell of it) (not everyone has my same passionate interest in anything Fentanyl related I'm sure).

So you were using heroin for all those years but only occasionally pissing dirty for it?

No I pissed dirty every month, but it was always coming back dirty for codein/oxycodone/morphine. I only tested dirty for “real” heroin those few times. I never noticed any difference in the high though. It’s always just a pure body high.

Honestly I don’t know the answer to your question but my impression is it was not a diluted form. That was never mentioned anyway. And I don’t think it was necessarily to “end suffering”, just to help soldiers who can’t be injected for whatever reason. And btw, I’m the same way on fentanyl. But because I’m a user. Just out of curiosity, if you don’t use why are you saving up the powder?

This could be because much of tar is said to be (although the few analysis don’t fully back it up) 6-monoacetylmorphine instead of diacetylmorphine.

6-MAM is actually said to be stronger/better than diacetylmorphine but would possibly explain why you weren’t pissing dirty for “real” heroin if they are looking for diacetylmorphine and the tar had 6-MAM.

Heroin also hydrolyzes to 6-MAM then morphine in the body fairly rapidly. They may be missing it for that reason.

Very interesting, thank you for that. The point I was making was that even when I tested positive for actual heroin, I don’t remember it feeling any different. Like I’ve argued before, I truly believe it’s tolerance related. The higher your tolerance, the less euphoria you’re gonna feel. Right now it’s only fentanyl that gives me a hint of euphoria.

Ok, so I read that first link you posted. Honestly most of that is common sense for any long term addict. But it didn’t specifically address the difference of “duration of action” & half life as you mentioned. Unless I just missed it.

Also it’s funny, there are 2 drugs there that are listed as having short half lives that, in practice, have the opposite effect on me: Valium & Marijuana. It claims Valium is only active for 2 hours. I always got 8-10 hours out of it. It’s the Xanax, if anything,that’s in & out rather quickly. And THC? I’ve read that it’s a little different to other drugs when it comes to half life. If you’re a daily user like me, it’s around 5 days. If you’re an occasional user, it’s 1.3 days. This article says it’s only 2 hours and that simply doesn’t resonate with my experience. If I get high, I’m high all fuckin night.

What do you think?

Somebody else picked up on this very issue, if memory serves me correctly, either on this thread or on the other one where we're having a chat. I just cannot find the post (as yet).

As for weed and THC: cannot comment or help! Probably smoked small PORTIONS of a joint maybe twice in my entire life (55 years). That shit just results in me emptying the refrigerator and then falling asleep within an hour (and can taste and feel the stuff for days after so not for this man I'm afraid! Lol!).

Ha! Consider yourself lucky mate. I WISH it still gave me the munchies. That’s one of the cooler effects. But I’m far too frequent a user to get all those extra goodies. I’d need to take a week off and man I just can’t do it. Need it for sleep.

12 years of at least a g a day of heroin addiction, fent came thru heavy these last 2 3 years and as many have mentioned, it doesn't seem to have that ummphh to it like good H does. i enjoy fent, i get somewhat of a euphoria from fent.. nothing like h tho. h lasts hourss and warma me up n has me happy enjoying the day.. whereas fent just gets me straight to itchy ass fuckin nose, eyelids tooo heavy to lift up... then bam! i lose 4 hours at least lol.. but yeah like stated above w my kinda tolerance, i aint even looking for a high anymore, im just tryna not be sick/stay normal.. but i explain it like this. H is a niice hash joint to the face, fucks u up for a min, but then your nicw n chillin for the rest of the day. but fent is like eating an entire tray of edibles .. you gonna blackout for 3 days easy n not even know it. lol everyone's made the edible mistake im assuming, yeah?? lol eat one n wait 30 40 mins n nothin, so ya eat 3 more.. n in 15 mins you a god damn vegetable lol

Hello.

Was that as a result of this thread being a trigger? Just curious (although sorry to hear about it).

Just curious because I can see how MANY threads around here would serve as triggers in spite of their initial intention being harm reduction. Pretty much the same thing as a bunch of clean users getting together for a game of cards (silly example but you know what I mean I'm sure), inevitably the conversation would eventually drift to reminiscing about, or romanticizing (mainly falsely?), "the good old days" of getting high and a discussion of various experiences and anecdotes and amusing experiences had while high, and it wold probably then only take one to say "let's go score for old time's sake" and, well, the rest would be history for most.
Hey,
Fuck you asshole, you just described a NA meeting!I.ve been reading your shite here on a subject you seem to know nothing about, (me neither). What if I may ask, is your qualifying " history" of WAY WAY more tolerance than we mere mortals. No IV, can't smoke on foil, and prefer codeine to morphine. All your words. And the phrase " I can attest based on what I've read, not on personal experience" is in fact a contradiction. If your here to learn,plenty of study info. If lonely/trying to make online connections ( but no drug lifestyle/problem/contributions/sound advice) to contribute, may want to ask yourself why here? access to pharma grade fent, didn't follow parameters for chosen roa, nor followed thru with sublingual.
But youre gonna write a HR report. Like a proctologist prescribing psych meds. If social and sharpening typing or social skills, check out the lounge. CH will give you plenty to do.
If, and here's my bet your'e trying to relate to the cool kids that traveled a different path than you for whatever
reason, read on; you dodged a bullet most will tell you if honest. WE all seem chummy cohesive, and even like some close as family. Truth is, If you're on here frequently. as I am drugs are still a problem in your life. Different stages of the same marathon that I for one had no idea what was signing up for as a youngster.
Wanna learn first hand? Volunteer at an exchange or injection safe site. The local mission. spend 10 bucks online hand out 5000 alcohol wipes.Offer to assist mobile doc on abscess day.
We ain't the cool kids. Nor snobs. But I for one, abso fucking lutely earned my place on this ship of fools. And I for one, don't appreciate the condascention and stereotyping above.

Wow. Dunno what set you off. And where codeine and morphine came into the picture I've absolutely no idea? As for Fentanyl: I deleted all of my Fentanyl related threads (of which there were dozens) so don't go making hasty judgments and assumptions re: what I may or may not know about Fentanyl.

And I sure ain't going to bother detailing my entire drug career and experience here to defend a post in which I was merely asking a question, for the sake of interest, of the person to whom I was asking the question (and who, strangely enough, didn't seem to mind answering the question or lose their shit because I asked).

As to why I'm here: I only came here looking for one thing (and which I eventually found) but given that it took some time and a lot of research and interaction with many forum members I figured I'd hang around because a) when it comes to Benzodiazepines and Antidepressants and related stuff I know my shit and have jumped in to help when I've figured it prudent to do so or felt "qualified" to do so or when asked for input and b) there's a lot more to BL than drugs and addiction thereto and harm reduction.

And this may come as somewhat of a surprise to you but there's more than just a few around here that are not users or addicts (myself included) at all (in some cases have never used at all ever). And based on one of your comments: I didn't see anywhere in the BLUA that NOT being an active user or addict precludes you from being a member. Feel free to point out to me the relevant clause if I'm mistaken.

You have a good day now.
