RCs Big n Dandy 4-FA (4-fluoroamphetamine) thread v.1.0

Status
Not open for further replies.
The abbreviation "4fmp" will get rather confusing rather quickly, as people begin to sample "4-fluoro-methyl-amphetamine" more often.

Yes, and I believe 4-FA (4-fluoro-amphetamine) to be a more useful name for this compound, longterm. I believe 4-fmp was created as a name only to avoid selling an RC with the name amphetamine in it.

For me it is a fairly effective stimulant with empathic and ectactogenic overtones. I have had it on about a dozen occasions (in doses ranging from 75mg nasally to 100-300mg orally) and I found it far less euphoric than mephedrone, methylone, or mdma. Even when combined with butylone it fell far, far short of mephedrone. Not to say that it was bad, just expect it to be more amphetamine-like than most other empathogens. It's great for keeping you going on those late nights out, but without blowing your mind like mdma and 4-mmc can.

Is it worth it? depends on how cheap you can get it. I can get mephedrone much cheaper and I prefer the high of mephedrone so I would usually opt for that. Now as far as the safety index, I would say that 4-fa (4-fmp) feels like it is probably much safer than mephedrone, due to the fact that you aren't anywhere near as fucked up, but then I have never taken 850mg of 4-fmp at once (I have taken that much meph at once! rough night). Even at 75mg nasally it wouldn't even touch the euphoria of 75mg mephedrone nasally. 4-fa definitely won't have you redosing compulsively like meph since 4-fa lasts 12hrs+ and by the end you will be so worn out redosing will sound like a bad idea.

Is it good? meh, it's ok. Would I do it again, yes! But it's not very high on the list of things to go out and buy. When I used to be addicted to amphetamines I probably would have been more enamored with it, but that's about how it is. Almost like slightly trippy adderrall.

Cheers,

Cleaner, less intense, slightly less empathogenic, longer-lasting meph. Think meph meets ordinary amphetamine. More euphoric than regular amp, less so than meph, more empathogenic than amp, less so than meph, longer-lasting than meph, and from my experiences, very mellow comedown - actually more like a plateau reminiscent of acid, as opposed to a "crash" like many empathogenics.

Don't expect it to blow your socks off like meph does when it start rushing; it's basically speed that feels a bit better in the beginning half and feels decidedly less shit towards the end.


All in all: probably the best pure stimulant (not empathogen) I have tried. If you like speed, switch to this stuff. Less bad side effects, better effects.
 
I've got a 1 gram of 4-fa and m-1 and planing to mix them tomorrow...

Question, 150 mg methylone + 100 mg 4-fa would be ok???

Im a male of about 75 kilos, im planning in take it with a mate, whos about 50 kilos TOPS... what do you guys think the right dosis would be???
 
First, I completely agree with an opinion that the nomenclature of this substance is 4-FA better than 4-FMP. 4-FMP is aggression of 4-Fluoro-(alpha)-Methyl-Phenthylamine, however it's not systematic chemical nomenclature (it's 1-(4-Fluorophenyl)propan-2-amine), moreover it's difficult to understand what it means unless having high-level knowledge of chemistry and psychopharmacology, and this name sometimes potentially confusing with other substances like 4-FMA. 4-FA, in contrast, many researchers may easily guess that it's aggression of 4-Fluoro-Amphetamine, it's clear. I think 4-FMP is named by some vendors because of the name 4-FA has a risk to be mistaken illegal Amphetamines so to prevent these problems they used 4-FMP. It's scientific discussion so I will use 4-FA.
There's an article about differences in vivo pharmacokinetics between d-Amphetamine (d-AMP), d-Methamphetamine, 4-FA, and 4-FMA in Japan (This article is Japanese only so I'll introduce the summarise of this in English). These data are not human's but rats so this may not be adopted to human, so please consider as only scientific data, but it's so precious data.
According to this article the half life of d-AMP (1 mg / kg, and so forth) in rats is approx. 100 min., in contrast 4-FA is approx. 205 min., about 2-fold longer. Interestingly, comparing d-MAP with 4-FMA it's opposite, d-MAP is approx. 110 min., 4-FMA is approx. 60 min.
There are many differences between human and rat in metabolise pathway so it should not too simplify to interpret of course, but if these differences could be neglected, medical research shows that the half life of d-AMP (as prescription medicine Dexedrine in the US) is about 9 hours in children and 11 hours in adults, then 4-FA has potentially over 23-24 hours half-life so it could be ideal medicine for AD/HD because it's no need to take divided and not too long to cause insomnia when comply to the prescription issued by specialist.
And this article also hypothesised the reason why 4-FMA has shorter half life than d-MAP, it says demethylation of 4-FMA is rapidly processing than d-MAP. I cannot any skeptical point in this hypothesis in my knowledge, so please point out if exist something skeptical point in it.
It may support that many researcher said that 4-FA is better than 4-FMA, because many people think that Methamphetamine is stronger than Amphetamine and indeed that's right, but it's not the nature of substances but the fact is only MAP is far more lipophilic than AMP due to -CH3 so easily penetrate BBB then has higher activity than AMP. In fact AMP is slightly stronger than MAP in vitro.
It's shown that Fluorine increase lipophilicity then it's no wonder 4-FA has stronger biological activity than 4-FMA.
Subjectively 4-FA is not so worth to recreational use however it has potentially more effective because due to has less adrenargic property than d-AMP or rac-AMP (Adderall or Dexedrine), it must reduce side effects like agitation, cardiovascular side effects and so on, moreover, weak entactogenic effect might have good influence to those who have AD/HD with Autistic Spectrum for 10-20 mg low dose.
I hope that this substance will not be only treated as "Drugs of abuse" but approved as Rx medicine for AD/HD someday.

(4-FA is completely legal in my country unless to sell or give to others, however it may show pseudopositive reacion to simple drug screening test then it has some difficulties for therapeutic use instead of Adderall which is illegal with no exception, even if doctor's prescription possessing here)

Quick question - might have been answered before.

Both times I've tried 4-FA I've had a g, and a g of methylone between two people. Would it be worth buying 2g of 4-FA for redosing over the night or is this overkill - would it still give the same rushes?

In addition: If I were to take the 4-FA, wait a while then take a bomb or two of mephedrone instead of M1 would the fiending still be apparent? I'm assuming yes, 4-FA and M1 however I don't find myself fiending on it at all but mephedrone is the most fiendish drug I've tried...

Bumping - This has got to the bottom of the second page and I'm ordering now. Has anyone ingested over a g of 4-FA to themselves over the night?
 
4-fluoroamphetamine lasts 12 hours or more... Less than 300mg was enough for me to overdose on and get hours of migraine headache and dysphoria.
 
Due to funding issues I ended up getting 1g of 4-FA and a few g'z of meph.

Let the fiending commence....
 
This does sound too good to be true. I better get my hands on some

It really is superb... Like meph, much cleaner, happy mood, no fiending + mixing a bomb or two of m1 blows you away.
 
Greenish 4-FA

My sample of 3g 4-FA just arrived this morning.

I'm a bit concerned about the appearance of my sample. Mine has a distinct benzole-like chemical smell and a greenish/yellowish color. In contrast to previous white odourless batches, i wonder if this one has more impurities. The greenish batch may even present nastier side-effects like it has been reported in another 4-FA thread:

pure 4-FM is a white odorless crystal. post-Boom production lots have varied in purity, with some greenish-tinted batches reported to cause an excessive cardio and kidney load, with one known case of an emergency room visit by a partaker with an undisclosed preexisting condition for treatment of myocardial infarction symptoms.

Allergy test performed with approx. 2 mg: Nothing bad.
Marquis reagent: dark orange

Anyone's opinion on the greenish batch would be appreciated.
 
will definately pay a bit more for this (4-FMP) rather than mephedrone...
 
I've been enjoying this stuff in small doses as a replacement for coffee. At no more than 1mg/kg I've found it to be satisfyingly stimulating for my entire (physically demanding) work day. It also puts me in a great mood for socializing (that interesting empathogenic touch), and my general motivation to do drone-like work seems to have greatly benefited as well. Great stuff, but I tend to get some lasting dry mouth sometimes. No other negative symptoms noted.

Can anyone comment on the solubility of this substance?
 
Update on my notes for this substance:

Under heavy stress I've gotten acute muscle cramps that are sharp and localized to one area. Could just be the effects of a stimulant allowing one to push oneself before realizing the detriment, but worthwhile to note anyways.

Impurities can be cleaned up using anhydrous acetone. A warmed solution will dissolve everything, and a freeze precipitation will crash out all the 4-FA without consequence.
 
Has anyone experimented with different ROAs? Can it be smoked? I'm considering getting this over mephedrone, I like amps and I really would enjoy a long lasting euphoric amp...it sounds like meth minus a lot of the shitty parts. You guys say it lasts long, altho it seems ppl aren't overly impressed with its entactogen/empathogen effects. Is it that this chemical has these properties but just doesn't compare to the intensity of mdma/meph or that the effects are negligible? I personally find meth or high dose dex to be a very social and euphoric high, I love when I get methbomb e pills, so I'm wondering will this probably be something I'd love?

I feel like getting 5 or so grams of this stuff will be much more bang for my buck and be more quality time and thoughts and activities done and its just cleaner than meph too. However if its not that impressive and its sorta just like adderall...i dunno..I have that...then I may opt for meph even tho i binge and fiend for it
 
i wonder how well this goes with mdai...

i plan on trying out 4fa again after leaving it by the side for a month, always had it streight but now was thinking it might go well with this... either that or methylone.... mind that i am rather sensitive to stimulation effects...
 
First post!

So here's my experience with this stuff, really great and subtle. Obviously I don't think I went about this in a very not so smart manner but at the same time I don't think this stuff is very harsh on the body.

Received about a gram of 4-FA on a Thursday and was used up within a week, with a break on the Saturday and Sunday. The days I took it, I would bomb about 50mg, then redose 2-3 times at around 50mg each time, and I never went over 230mg in an entire day. No comedowns, no crashes, although I would supplement with a good bowl or two of dank towards the end of the day to help sleep. The above posters saying it lasts 12 hours is I think kinda bullshit, it's more like 4-6 hours, with the nice entactogenic tingles around the 2-3 hour mark. I used it primarily as a replacement for addderall as a study/school aid and I think it does well in this area, especially I noticed it made me much more sociable. Not that I am anti-social, it just made interacting with people pleasurable in a sense. I did notice after shutting out the lights after going out to smoke weed and heading for bed was a distinct psychedelic effect: I looked out the window and the buildings far off in the distance would kinda warp and breathe, but that's about it, and I'm guessing this is the serotogenic activity here. I also think it had a lot to do with me smoking weed but eh guess we wont know for sure.

It doesn't have the push of the regular amph, and definitely none of the harshness that comes with regular amphs. The friday after I ran out I felt a bit tired, but was more tired than usual the second day after stopping, but honestly, other than a little lethargy, there wasn't any other complaints.

I can kinda see this being used a few times a week, maybe even everyday. It might seem to have serotonin effects but from what I have read and from personal experience, this is very slight and quick to recover from, especially when taking your daily vitamins/eating right and whatnot.

Oh and I started taking the 4-FA about a month into my piracetam regimen, and about a few days after stopping the 4FA, I added oxiracetam to see what it does.

I ordered another gram of 4-FA and will keep a more detailed report of it when it arrives. I hope to be more controlled in terms of using it but who knows how it will play out. I also ordered 500mg of MDPV but I know ahead of time to take this substance with caution. Also, these are being used for study purposes.

And for what it's worth I plan on trying low doses of 2C-E, like 5mg as a nootropic, but I think ordering some 2C-D will be a better idea, eh who knows how it'l go.
 
No amount of caution can curb a shitty experience with peevee, friend. It's also not a very valuable study aid--gets jittery and uncomfortable quickly.

Glad you liked 4-FA though; great chem IMO.
