Butyr-fentanyl Drug Info

Please post info about butyr-fentanyl here.

Can anyone add information about:
  • names / synonyms
  • molecule
  • dose
  • duration
  • side effects
  • have there been any reported incidents with this compound?
  • since when has this research chemical been available?
  • legal status
  • stability of the molecule / compound
A thread for experiences with butyr-fentanyl will be created if and when it is necessary.

_____________________________________

Short Name: butyr-fentanyl
Synonyms: B-F, butyrated analogue of fentanyl
IUPAC Name: N-(1-(2-phenylethyl)-4-piperidinyl)-N-phenylbutyranamide
Molecular Formula: C23H30N2O
Molecular Mass: 350.5 g/mol



It is the N-butyramide analogue of the potent opioid fentanyl.

_____________________________________
(end mod edit)

Dose (pure B-F)
intravenously 0,05-0,3 mg
smoke 0,1-0,5 mg
sublingual: 0,3-1 mg
oral: about 1 mg

Pure form is rare in the trade. Most is sold to a mixture consisting of:
1 mg of B-F and 1 g of inert substances (lactose, etc.)

Dose (mixture)
intravenously 50-300 mg
smoke 100-500 mg
sniff 100-500 mg

Duration
It depends on the method. The injection and smoking are the fastest. It works immediately after the injection /evaporation. It works for 20-40 minutes. In the beginning, (in contrast to the normal of fentanyl), the BF feels a clear “opioid” entrance (hihihi opiate orgasm).
Sublingually or orally, longer-lasting (several hours), but the effects are very weak.

Very good it is snorted. The effects appear after a few minutes, the effects last for1.5-2h, and are very nice )

Smoking and retraction of the nose is the best way.

Effects:
The effects are between fentanyl and heroin. Sedation is weaker than fentanyl, but euphoria is stronger. Euphoria B-F is similar to heroin. Other effects are identical with the fentanyl.

Re: Butyr-fentanyl - new opioid

wow, that looks dangerous as all fuck, especially if it is being sold cut like that.

Out of curiosity, is this a new chemical? Fentanyl has a number of analogs, one being the first "designer drug" having been created by clandestine chemists specifically to circumvent laws.

Because of this we have the implementation of the Federal Analog Act and for the first time the U.S government attempted to control an entire family of drugs based on their structural similarity, rather than scheduling each drug individually as they appeared.

Re: Butyr-fentanyl - new opioid

This is absolutely frightening.

Out of curiosity, is this chemical being sold online (RC vendors? Higher up than that so that you actually have to "know someone" to get it?) or is it at the street level?

Re: Butyr-fentanyl - new opioid

On the plus side this would be deemed a controlled substance isomer of both α-methylfentanyl and 3-methylfentanyl in the US and therefore would be a controlled substance in its own right, without even needing to take the Analog Act into consideration.

That's about the only good thing I can say about this one really. Crude cutting such as mixing batches of solids with inert material sounds like a disaster waiting to happen. Nothing homogenous about that and hotspots will arise. Fentanyl derivatives in general are also a disaster waiting to happen in the hands of recreational users. If this hits the market in any volume then deaths will inevitably follow. China White circa 2012? Let's hope not.

Re: Butyr-fentanyl Drug Info

just wanted to bump this up as it seems to have died on the vine. i read some reviews on "butyr-fentanyl" and some "more to come" type info. I'm really interested from a research standpoint only of course. does anyone have any news?

Re: Butyr-fentanyl Drug Info

There's some new info:

1. Dosing I have written about in my first post was to small, especially for an opioid-tolerant person. First tests were made on individuals with no opioid tolerance.

2. Substance is very addictive, especially taken IV, which gives best results. Unfortunately, tolerance develops very quickly.

3. Please, be careful with this. Beta-ketones are a child's play comparing to very active opioids like this.

Damned be that day when I took this for the first time ...

It'd almost certainly be considered by Health Canada to be a controlled substance analogue of several fentanyl compounds explicitly named there.

Re: Butyr-fentanyl Drug Info

so we're all in agreement that it's just as much of a legal risk as any other sch-1, and therefore will probably never make it onto the rc scene

Re: Butyr-fentanyl Drug Info

It is available on an invite-basis now, but that invite is not difficult to get. Butyr-Fentanyl is very much present on the (open) RC scene. Via slightly blacker markets other fentanyls are also easily available.

Re: Butyr-fentanyl Drug Info

The shop that wes selling this chemical has now added a new fent derivate : 4-fluoro-butyr-fentanyl.
CAS : N-(4-fluorophenyl)-N-[1-(2-phenylethyl)piperidin-4-yl]butyramide
Any info on this one ?

They have now added butyr-fentanyl on blotters, should it be taken sublingally ?

Re: Butyr-fentanyl Drug Info

I took 4fbf twice. First time 3 mg IV (i have tolerance) - it seems to be more euphoric than B-F. Few days later I took 4 mg IV and it worked very poorly.

The B-F blotters are working very good sublingually - 2mg is enough.

Is it possible to use the blotters via iv, as in soaking them in the cooker or another method of removing the substance from the blotter?

They dissolve in water very well. I suggest warm/hot water extraction. Be careful, 0.5mg is enough for person without tolerance.

Re: Butyr-fentanyl Drug Info

Does anybody know the BA% of butyrfentanyl orally, rectally and nasally?

Do fentanyl and other substance analogue bioavailability percentages change or stay the same?

EDIT: In my country it's sold legally and it's sold in the form of a nasal spray. 10mL bottles containing 25mg (as each spray gives you a dose of 0.25mg, or, 250µg) of BF in sterile saline solution, supposedly enough for around 100 sprays.
But I figured with the right equipment and knowledge, it could possibly be used orally or maybe rectally even.
So again, with the BA% of this analogue, does anyone have any idea, or could it possibly be the same as fentanyl?

According to wikipedia, these are the bioavailability percentages of fentanyl, regular fentanyl that is, no analogue:
Bioavailability;
92% (transdermal)
89% (intranasal)
50% (buccal) (I was just reading about real quick but couldn't wrap my head around it, what form of administration is this? Not the same as taking it sublingually i take it, right? So then, how is it administered?
33% (ingestion)
-
Protein binding 80–85%
Could someone explain to me what this means? What's protein binding?
-

I apologise for all the questions, but how else are you supposed to learn and understand, right?
I'm doing some reading at the same time, but I figured I could ask here as well, I hope that's okay!

EDIT: I think I understand buccal administration a little better now, it's where it's placed between the cheek and the gum between the teeth, or the gum and upper lip. Right? If I'm wrong, please explain it to me.
Or if there's a link here, which I'm now going to try and find, please link me to it.

Thank you!

Re: Butyr-fentanyl Drug Info

My pink elephant was able to acquire 500 mg of this chemical even through it is illegal to own in his country.

He said that it is definitely a potent chemical with euphoric, opioid like effects. In his personal opinion it is not as dangerous as usually described. He thinks this somewhat excessive emphasis on caution may lead to some opioid tolerant users to taking irresponsible doses. There are a few examples of this on other forums.

Also he does not think that characterisations of fentanyl analogues as lots of sedation and little euphoria is fair, for him the two go hand in hand with increased doses. In very small doses he tried first it had a somewhat stimulating effect. Compared to other opioids he has experience with (codeine, tramadol, morphine, AH-7921) this one has much less histamine release and nausea.

The length and strength of the effects do depend dramatically on the method of administration, so he would advise everyone to start sub milligram, and wait for the effects to come on, to make sure to know how high he/she is going to be to avoid overdosing, especially in the case of buccal or transdermal administration (aka liking one's skin and putting the substance on it like he does). If he/she is worried that he/she has taken too much a stimulant to stimulate breathing comes handy or naloxone if he or she does not mind ruining the high and is seriously worried.

I don't think that injecting butyr-fentanyl is responsible, as there's no time to stop the od happening and apparently the effects may be more euphoric but last much shorter. Also, addiction can quickly develop this way. He has read that from few people who have first hand experience that methadone and buprenorphine do not treat the withdrawal as well as they treat withdrawal from other opioids.

He can't comment on doses because he's sure that the the stuff he has received has been cut, just not by how much. Without much tolerance he smoked 3 mg off foil only to get a moderate codeine buzz.

I would also advise everyone to not go for 'the nod' and keep pushing the envelope as this is an untested chemical it's suppression of breathing is notable.

Re: Butyr-fentanyl Drug Info

This stuff is strong in its pure form. Strong enough that 20 mg IV busted through a naltrexone blockage with ease. IV is just irresponsible with this substance, and even smoking can be dangerous as you don't get a standardized dose every time you hit it. DO NOT SELL OR SHARE THIS WITH FRIENDS. if you want to play roulette with yourself that's fine, but to engage others is immoral and irresponsible.

Someone spent months of effort getting this (And AF) to stop being produced. It mostly was. It got damn hard to source when the labs heard the gospel. Saddened to see it fucking everywhere again =(

Waves of deaths are the antithesis to a healthy and growing research chemical scene development.

I know this is an old post, but I would advise ANYONE who is purchasing any fentanyl analog or profoundly potent opioid to contact the vendor, and ask what machines and methods they are using to make sure it is absolutely certain to be uniform. I would even ask for photo evidence. The smallest hotspot could be your last.

If this hits the market in any volume then deaths will inevitably follow. China White circa 2012? Let's hope not.

I don't believe this is the truth.

I may be wrong but under the CSA only the optical isomers are controlled with 3-methlyfentanyl and a-methlyfentanyl. Positional isomers are not covered under the section of the CSA where 3-methlyfentanyl and a-methlyfentanly are scheduled.

As far as I know B-F is a legal research chemical and possibly a controlled substance analogue.
