Drug info - Butyr-fentanyl Drug Info

[chemman]

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.

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.

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.

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?

[Phenoxide]

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.

[evilbrood]

This chemical is very scary!

Anyone else has informations about this chemical ? There is almost any information on the web, or I am a bad searcher

[FPU4eva]

its on the market now, dident know they were cutting it but this and another fent analog are out their, a few more will be hitting

[viator]

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?

[chemman]

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 ...

  Would it be legal ?
  

[Tripdisaster]

Sorry for not mentioning it, its a Canadian law.

[Phenoxide]

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

[viator]

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

[Synaps]

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.

[tstacey95]

i found a vendor selling this and am planning on buying it mixed with lactose (an inert substance). however, the only roa's ill use are sublingual (spit out once you feel effects) or smoking (stop inhaling when you feel effects) to avoid hitting a hotspot and dosing all of it at once. and viator, can you post links for the reports youve read? they seem pretty scarce

[evilbrood]

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 ?

[johnsonO]

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?

[johnsonO]

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

Obtained 1 2mg blotter, 1g 1:!00 mix and sample of pure product, will post a writeup later, but swim can say for sure the blotters do not dissove with cooking
