so heres what i've gathered so far about 4-FA aka 4-Fluoroamphetamine (mostly from wikipedia.

"4-Fluoroamphetamine (4-FA; PAL-303; "Flux"), also known as para-fluoroamphetamine (PFA) is a psychoactive drug and research chemical of the phenethylamine and amphetamine chemical classes. It produces stimulant and possibly entactogenic effects. 4-FA is a relatively rare drug on the illicit market, although it is sometimes sold as a designer drug along with related analogues such as 2-fluoroamphetamine and 4-fluoromethamphetamine, among others."

"Effects

The subjective effects of 4-FA include euphoria, increased energy, mood elevation, excessive talking, bruxism (jaw clenching), insomnia and suppressed appetite.

4-Fluoroamphetamine is a potent stimulant and serotonin releaser as with other para-substituted amphetamine derivatives, but is both significantly less potent as a serotonin releaser and much less neurotoxic than related compounds such as parachloroamphetamine and paraiodoamphetamine, with both serotonin-releasing potency and neurotoxicity increasing down the halogen series 4-FA << PCA < PBA < PIA,[3][4] while conversely the dopamine reuptake inhibition produced by 4-FA is stronger than that of either PCA or PIA.[5] 4-FA also produces less hyperthermia than similar compounds such as PMA, 4-MTA and 4-methylamphetamine, but both hyperthermia and neurotoxicity are still likely to be complications of overdose or excessive use of 4-FA."

Have any of you tried this substance.. some first hand reports would be interesting!

Here are some erowid TR's http://www.erowid.org/experiences/subs/exp_4Fluoroamphetamine.shtml

I actually just started doing some research on this and have been debating on whether or not I want to invest in it.
So far I have only found 1 vendor and the price isn't terrible, but it isn't inexpensive at all.

I would love to hear more trip reports and more info on the physiological and psychological effects. It seems like it could be comparable to MDMA, but I would prefer an actual report over my assumption before I go buying this stuff.
Also, any info on drug interactions would be great (including opiates (bupe too,) benzos, ssri's, snri's, and muscle relaxers.)

p.s. I am not really sure if this post even makes sense right now - i am pretty benzoed up and this took me like 15-20 minutes to type out, so i will be sure to reread this tomorrow and edit if necessary.

Yes it feels kind of MDMA. Makes you emphatic, really social and overall really good feeling. Even when taken by oral, you get nice tingling feeling up to you're head while it comes up. It has also amphetamine like speediness and makes your head clear. Works about 4h, you can boost it by one or two times but after that it won't work anymore.

I have sampled it two times at 100mg (oral).

Nice euphoria. Good for a chill afternoon with friends and good music. I haven't felt any negative effects on onset, comedown or afterwards. I usually take two 5-htp (100mg) before I go to sleep.

I think I will try 150mg (oral) next time.

Sounds to be really good, always meant to try it but never quite got round to it. From all reports i've heard do not snort, it burns on a par with the 2cx's apparently

If you havnt sniffed a 2c-x before id advise against it, never quite felt pain like snorting 2ci, though it does only last 15 minutes

Insufflation is not recommended. It tastes horrible as well. Rectal admin should suffice for those looking for a quick onset.

I must say that this substance is very promising. I've been using it frequently as a study aid for the past few weeks and have no serious complaints. You get your run-of-the-mill amphetamine sweats, tight muscles, irregular bowel movements, lack of appetite, etc... but other than that 4-fa appears to be a winner. Mind you, the duration is extremely long, although I don't find that to be much of a bother. %)

My TR: http://www.bluelight.ru/vb/showthread.php?t=493388

Addiction potential is definitely there for those prone to 'fiend' for that initial rush.

There are also the obvious risks involved when playing with RCs:

Chemically, well ya on some rather-rudimentary levels it's pretty close [to mdma]. But 4-fluoroamphetamine's structurally going to be closer to 4-fluoromethcathinone (4-FMC), which IS close to 4-methylmethcathinone (4-MMC/meph). So by transitivity, the stuff's going to be pretty darn close to mephedrone, for better or WORSE.

Meaning the risk of neurotoxicity (mainly), as well as addiction, is also going to be higher than the more classical amphetamine phenethylamines (like MDMA), given (among other things) that it's more closely related to mephedrone than to MDMA.
my implication would be that that misc. heart issues are a serious threat for all of the substituted cathinones (either on the RC market, yet to make it there, or not suitable for it). So ya, 4-MMC would act in a similar fashion to 4-FA on a global substituted cathinone level (again, whatever that may be, with the lack of long-term research), and given that it's similar the similarity of these two (or three) chemicals with respect to their optional substitutions/replacements, I'd say that they'd have similar physical effect means when compared to all substituted cathinones. Meaning any unknown dangers for 4-FA would be quite similar to unknown dangers for 4-MMC. I say "unknown," again, as these are modern-age RCs. If you get what I'm sayin'...
4-fluoro-amphetamine has been found to carry drastically less risk of neurotoxicity than mdma, as is largely the case with methylone too (both studies are Nichols et al., iirc). Also, I don't see why we should consider mephedrone more neurotoxic than MDMA on an a priori basis. As of yet, we don't really know what its receptor affinities, etc. are like, even.
I don't think that there's been rigorous study on the danger of 4-fa's metabolites (although they've been identified), but I believe that you have little to worry about--4fa won't metabolize to an ephedrine-like compound (in this case, we'd be worried about a cathine derivative, I believe).

5ht2b agonism is a more open question.

well the first 100mg gave me a slight mood lift, feeling slightly stimulated, in a very good way... i later bombed another 100mg's and waited 30 minutes, sniffed a 20+mg line of 2C-E and now feel very stimulated, euphoric, jaw clenching slightly... slight visuals from the 2C.... but definately feeling more stimulated than 2C alone, i'm sweating quite a bit, but feeling on top of the world.... sort of like a cleaner version of mephedrone

i've prepared 200mg parachutes for me n a couple of mates to sample tonight at a Drum n bass party... should be interesting

cleaner version of meph?! sounds amazing, and like someone else said, too good to be true!

Anyone have any info on my previous question about drug interactions?

Going to order a gram or 2 of this in the coming weeks, will report back when I have sampled it. Sounds promising.

The abbreviation "4fmp" will get rather confusing rather quickly, as people begin to sample "4-fluoro-methyl-amphetamine" more often.

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.

In addition to the above - I don't know if it was because of the mix of methylone but there was definately light visuals both times I've done this (textures, patterns).

I've been reading from many about the supposed low neurotoxicity of 4-fa if compared to other halo, but never seen any source for it. Does anyone have link or paper related to 5-fa's toxicity or pharmacodynamics?
And another thing I don't get: anyone who tried it seems happy with it, then why it's so rare and unknown? Theories?

It's already rather confusing; I thought that this thread was about that compound when I read the title.

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. I would think that 4-fluoro-methyl-amphetamine (4-fma) would be better and probably more 4-mmc like.

For me 4-fa 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 one oral dose! 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,
SimStim

PS- the burn is not as bad as 2c-x compounds. It is VERY bad, but it subsides very quickly and does not linger or cause me to feel like I am going to drown in mucous and then vomit like 2c-e and 2-ct-2 do (but not for some reason 2c-i).
