RCs Fluoroamphetamine comparison/combination thread

[Poodles!]

There's plenty of info out there in the individual threads about the Fluoroamphetamines but I constantly see people asking about the differences and how this F(M)A compares to that F(M)A or which is better suited to what situation. I figured it would be useful if we had a thread dedicated to peoples opinions on them such as which are their favourites and the circumstances in which they're used. Would be a good thread for people to talk about their experiences with combinations too.

Here's my opinions anyway. I'm looking forward to more experimentation with 4-FMA at higher doses. Maybe this is more suited to BDD, I'm not sure. If any mods feel it should be somewhere else then feel free to move it.

Big n Dandy 4-FA thread
I find this one to be very recreational. Euphoric first couple of hours with hints of MDMA like empathy. Can be quite subtle and can be used in pretty much any situation where appearing "normal" is important, higher doses become more of a roll than a plain stim though. After the first couple of hours it begins to fade into pure stimulation. Redosing is useless after this point. Comedown is long and smooth, you don't really notice it if you're busy or interacting with people. Doses below 60-70 mg oral can be useful as a study aid. 50-150+ mg for recreational use.

ADD 4-FMA thread
Only recently started experimenting with this. This is a great all rounder. Can be used as a study aid similarly to 4-FA (>70mg) but has more of a push. The dose-response curve with this one is odd though. Unlike 2-FA/2-FMA which have a ceiling on the recreational psychological effects, this one just keeps on going as dose increases. Plugging 150-200 mg of this can be a hell of a rush and once you reach a certain dose (not what dose yet) the euphoria just seems to last for ages (but still sleep.. then wake up still buzzing )! Could get quite messy i think. I've never tried Methamp, but from my limited experience, I'd say this is the closest what I imagine Meth would be like.

OD 3-FA thread
ADD 3-FA thread (merge?)
Quite tweaky. This one is feels like a straight stim and the FA most likely to cause anxiety. Could be recreational or used as a study aid depending on your preference. I don't find it brings anything recreationally than 4-FA or 4-FMA can't bring or anything productive that 2-FA or 2-FMA can't bring. Not sure about dose for this one as I've not taken it very high but similar to d-amp, perhaps a bit less potent.

3-Fluoromethamphetamine
No real info on this one (prove me wrong!)

2-Flouroamphetamine
Wiki
2-FA Mega Thread
2-FA/2-FMA Metabolism thread
This is by far the best study aid IMO. The psychological effects and euphoria seem to have a ceiling not much higher than 50-60 mg oral that means you're less likely to get distracted if you dose too high. It's very calm considering it feels like it has little in the way of serotonin activity. Unlikely to cause anxiety unless you're especially susceptible to it or redose too much.

2-FMA Megathread
Other 2-FMA thread (merge?)
2-FA/2-FMA Metabolism thread
VERY similar to it's non-methyl cousin in pretty much every way, but has a little more to give in the way of euphoria, but can be a bit more tweaky and not as smooth. Vapes much better than 2-FA, but I prefer other ROA's.

Edit: I have a couple papers regarding a couple of the flouroamphetamines, if anyone else knows of any other research papers or articles concerning these, or regular Amp/MethAmp for comparison then PM me. I'd like to collate as much info as I can such as binding affinities, monoamine reuptake inhibition/release data etc. I'll put what I can find into a spreadsheet and hopefully add anythng useful to the first post. Cheers!

It seems to me that many vendors are not distinguishing between the FA and FMA variants, so they are selling the same thing under the banners of 3FA/3FMA, 4FA/4FMA. I've never tried the FMA variants, i have tried 3fa and 4fa and quite liked both. Are 3fma and 4fma very different to 3fa and 4fa respectively ?

 

[Poodles!]

I've never tried 3-FMA, I can't find a vendor selling it! And 3-FA felt pretty much like I'd have expected it to from the data in the 3-FA thread which I'll quote here:

I'm pretty sure it is, but I don't have a source to back it up at the moment. I believe it's around 1200% for meth and 400% for cocaine. It doesn't include norepinephrine levels as well, which is problematic because if they're even higher the abuse potential might be diminished.

It's included in the figure. Keep in mind rats are pretty fast metabolisers.

For comparison
d-Amp
EC50 NE release (nM) 7.2 ± 0.44
EC50 DA release (nM) 8.0 ± 0.43
EC50 5HT release (nM) 1756 ± 94

m-Fluoroamphetamine (3-FA)
EC50 NE release (nM) 16.1 ± 1.7
EC50 DA release (nM) 24.2 ± 1.1
EC50 5HT release (nM) 1,937 ± 202

p-Fluoroamphetamine (4-FA)
EC50 NE release (nM) 28.0 ± 1.8
EC50 DA release (nM) 51.5 ± 1.7
EC50 5HT release (nM) 939 ± 76

This brings one to question the overall usefulness of release data as well, if basal dopamine increases in the nucleus accumbens don't appear wholly similar to the release EC50s. The question remains as to why 3-F-AMP would be stronger releaser of dopamine than any of the others, which is somewhat mysterious.

Seem to have lost some the last half of this post for some reason...

Can't remember what I actually put but it was about the F(M)A's I'd tried being definately different to each other... with the only possible exception being 2-FA and 2-FMA where the differences could have been set and setting. But folk from the US and EU seem to be having similar experiences despite being from different vendors. Whether the vendors are getting them from the same supplier I don't know. It's worth taking into consideration though.

 

[SilentRoller]

Apologies if this is off-topic slightly, but does anyone have any information on 2-FMC (as it is part of the 'fluoro' familly of compounds). I'm looking at sampling it, although I'm not sure of its side effects etc.

 

[Poodles!]

I've tried 2-FMC. It's the worst cathinone I've EVER tried. It's not worth it. The only cathinone I would take again nowadays is bk-MDMA, possibly 4-MMC (Mephedrone) if I could guarantee it was pre-ban UK quality (which supposedly contained about 10% 3-MMC)... I wouldn't mind finding some of the pure indian stuff that's been going around to see if mixing it with 3-MMC does infact produce that pre-ban experience though. 3-MMC has everything 2-FMC has, but better. I've not tried any of the other FMC's though but the general consensus is that both 3-FMC and 4-FMC are superior to 2-FMC, although niether 3/4-FMC have been that popular.

 

[SilentRoller]

Care to elaborate on how 2-FMC was the worst ever? I'm quite curious about 4-FMC and 3-MMC (although I'm not sure how 3-mmc is on the heart, compared to methylone for example)......is 3-MMC/4-FMC toxic feeling.

you havent tried 4memabp then?

2-fmc has its uses if you get the dosing right and dont mind the short duration and sweating

 

[SilentRoller]

From what I heard, 4memAPB is basically an hour of cardiovascular stress.....My idea of hell. Is 3-MMC easy on the heart?

 

[done juan]

never tried it. but from what ive researched it seems like its one those chems that dont quite get you to where you want to be. i think they key to 4memabp is oral and not insufflation, but in terms of pros/cons, most people will want to give it a miss

 

[Poodles!]

Well, 2-FMC was just a vanilla stim that peaked for about 30 mins and each redose would be worse than the last. You'd go through a gram pretty quickly and not really get anywhere in terms of euphoria. the FA's are much more worthwhile chems. The only reason I mentioned 3-MMC I bought some recently and found it was a bit more powerful than mephedrone in terms of stimulation but lacked the serotonergic effects that 4-MMC had such as empathy, anxiolysis (3-MMC is had a bit of an anxious edge to it at times) and smoothish comedown... much more of a crash. As I said, when it comes to 3/4-FMC some people prefer the one, some people prefer the other. But 4-FMC would probably be your safest bet. I'd recommend trying 4-FA or 4-FMA instead if it's a recreational stim you're after. Look at my comparison of the two in the first thread. Duration is the only issue. But for some reason I slept quite well on 4-FMA even though I woke up still buzzing! (I did have a 2 or 3 mg of etizolam though)

Edit: I have a moderate tolerance to etizolam

 

[SilentRoller]

How is 4-FMC for duration at sleeping? Is it quite heavy on the heart like meph? I would probably go down the nasal route with this one

 

[Poodles!]

Decided to risk a small sample of of 4-MeMABP... And you're spot on. It's Horrible. 3-MMC is about as hard on the heart as pre-ban 4-MMC in UK/Europe, but the fact that it's more stimulating and anxiogenic, means you're EVEN more likely to want to redose. I'd suggest only getting it to mix with 4-MEC/EMC if you like either of those (both trash) or with post ban 4-MMC which is synthed via a different route and doesn't have 3-MMC as an impurity, and hence why it feels weak compared to the pre-ban chinese stuff.

But this is an amphetamine thread, not a cathinone thread .

Edit: From what I've heard about 4-FMC is that it's easier on the body than meph, but isn't as euphoric. I can't remember if it was 4 or 3-FMC that was in Charge+ along with caffeine and some random inactives like vitamins etc.

 

[done juan]

Poodles did you get anything positive from 4memabp?

 

[Poodles!]

Nothing, Just some boring stimulation that was mostly peripheral. Subtle mood lift, but I really just couldn't be bothered with it as higher doses didn't seem to add anything to the central effects, just more physical stimulation. Even Buphedrone was better (same, but without the para-methyl ring substitution)

Edit: adding the methyl to the 4 position usually decreases DA affinity but increases 5-HT affinity. Since Buphedrone seems to be an NDRI (if it is a releaser, it's a pretty weak one), 4-MeMABP is mostly an adrenergic drug with very little in the way of Dopamine release/reuptake, and negligable serotonin effects. It may be a weak SRI, but for anyone whose tried SSRI's, you'll know that this isn't particularly recreational. Pentedrone is pretty much just a more potent version of Buphedrone as increasing this chain increases potency or reuptake inhibition. But if you're at that point you way as well just go for a-PVP or MDPV (both potent NDRI'S with that pentyl chain).

 

[6apbhmm]

Same here, I was "lucky" to receive free sample of 4-memabp once, easily the single most useless "drug" I ever heard of.

But wait, wasn't this thread be supposed to be about combos of flouroamphetamines with other drugs? If it is, I can only contribute with experiences with alcohol + 4FA (quite lot of them actually):
result? Exactly what you would expect, it's the same as combining MDMA with booze. If both ingredients are in sane amounts, it's great, booze increases both the euphoria and horniness. If you don't redose FA much and just keep drinking, you won't notice much comedown at all (not until you wake up the next day..).
You obviously want to drink more water, but no need to drink tons of clean water every hour, after all this leads me to an interesting myth that surrounds stims (and especially MDMA). In every document about MDMA you hear there is a giant risk of dehydration which is total bullshit, it's not that bad. You sweat and pee more but its not hectolitres. Actually I believe many times I caused more stress for my body by drinking too much water when rolling because I heard it from everybody. If you don't feel thirsty, don't, it's only going to stress kidneys more.
Normally in summer I drink 3-4 litres a day when sober so being high I needlessly drank maybe 8 litres more and only felt so full.

Heck I never saw anyone or heard from friends that somebody had to call an ambulance because of dehydra.

 

[androoo]

I'm slightly confused as to what sort of starting dose to choose with 4-fma? I think its due to all the conflicting reports! I see reports of people being content with 50mg and warning to go no higher then 100mg but also people quite happy with 150-200mg doses? I understood that that sort of dosing was more for 4-fa and 4-fma was more potent?? looking forward to doing my own tests tho
