RCs 2-FMA (2-Fluoromethamphetamine) - Megathread

1) I am prescribed vyvanse. I typically take anywhere from 70-120 mg a day to get where I like to be. When my script runs out early, I substitute with either 2-FMA or 4-FA (I've been switching between the two because I'm still trying to find out which one I prefer as a replacement for when my script runs out). For me, personally, 35-38 mg 2-FMA (pink and fluffy batch) gets be going pretty good and lasts allllllll day long. Be careful, though. Any more than 40 mg and it gets more uncomfortable than functional: noticeably increased heart rate, uneasy body load, so stimmed to really get things done properly.

2) To try and stretch my vyvanse script, sometimes I'll take 35-38 mg 2-FMA in the morning. Then an hour later, I'll take 40 mg Vyvanse. This combination is WONDERFUL for days when I'm exhausted for whatever reason, or need to wake up extremely early. The 2-FMA provides a feeling of complete alertness, and the d-amp from Vyvanse really makes me want to accomplish.



You said it! The pink stuff is wonderful

Awesome, thanks for the information. Are the doses you indicated oral? I sampled some 2-fma that I think was of particularly poor quality -- 75mg oral did not produce even threshold effects (though the same dose insufflated was mildly effective -- but I don't prefer that ROA for my utilitarian purposes). I'm going to sample some from a new source shortly and I'll keep in mind that an active dose may very well be much lower than that. Also I'll keep a lookout for pink 2-fma.
 
im excited to try this one. unfortunately the only time i make decent money is when im on summer break, defeating the purpose of its use.

how well does this work as a study aid compared to adderall or methylphenidate?

I have only ever taken 2-FMA orally. I put it into gelatine capsules.
 
Also, I found HighestWhenLow's post on page four to be pretty ridiculously close to my experiences. It is extremely easy to get to the point of regular use. The smooth comedown as well as almost complete lack of side effects honestly makes it rather difficult to reinforce that its probably not the most healthy. The worst I have gotten is slight kidney pain and palpitations but those are honestly pretty rare Recently finished a gram of it and plan on taking a nice long break now. I find it almost comparable to MXE in that you never need it , but things would feel a lot more swell on it.

Dude... yes. Kidney aches and heart palpitation are my tell-tale signs that I'm pushing it even by my standards. You summed it up perfectly: you never need it, but things seem easier when you have it. My use has been pretty frequent (3-5x/week) for several months now, and some new side-effects have been popping up the past 3-4 weeks that weren't present initially, specifically blunted emotions, some OCD tendencies, and this occasional discontent where some days I'm constantly craving the next activity/part of my day only to be dissatisfied when it arrives and to start craving the next thing; an inability to be still and content is what I'd call it. Will definitely be taking a LONG break from this one, i've reached the point of over-use where taking the stuff feels like more of a chore than anything.

Below if my older post that Nimhod references in his post.

I just wanted to share my experiences with this chem from an addiction/habituation perspective, having gone through 1g of the stuff in approximately 2 weeks and with another 2g on the way. I am predisposed with an addictive personality, so my experiences may be taken with a grain of salt, but I personally find 2-FMA to have significant psychological addiction potential. The functionality of this chem, along with its low side-effect profile and pleasurable effects seem to cultivate psychological dependence.

By this, I mean that being able to take 2-FMA throughout daily life (work, school, etc.) and enjoying the effects without interfering with my normal tasks makes it all too easy to fall into daily use. 2-FMA is actually highly effective for school reading and assignments and makes work more enjoyable day in and day out, most likely because I'm riding a steady stim buzz the whole time.

Daily use is an easy habit to fall in to, and one that is hard to break as long as I have more in my stash, mostly because of the simple little question of "Why not?" And to be honest, I still have yet to find many reasons why to not use it as long as I have it, other than abstaining for abstinence's sake.

Others have reported not feeling compulsions to redose with 2-FMA. I disagree, but I think it depends on how you define compulsions to redose. If others mean that the drug's come down does not produce uncomfortable or undesirable feelings that prompt redosing, then I agree with them, because the come down is certainly not unpleasant in a way that creates the desire to redose. I personally do always feel the desire to redose, however, in order to chase the pleasure and productivity of the initial dose. Redosing becomes even easier with the low side-effects profile of 2-FMA as a safety net, preventing serious complications from continued dosing.

The reason I find 2-FMA habit forming but NOT addictive in any physical sense is that I used it pretty much every day I had some in supply, maybe skipping 2-3 days in a 2 week period, but I experienced absolutely no withdrawal symptoms after discontinuing use when my supply ran out. I pretty much just went back to life as normal, ordered some more, and while I do miss the zest it added to my day I don't find it hard at all to continue with my day-to-day life.

These are just my experiences and reflections to date, hopefully someone finds them useful or informative. I will have another (larger) supply of 2-FMA by the end of this week so I will update my experiences in a couple weeks.
 
Weird question, but does anyone know if 2-FMA is a 5ht2b agonist? I wouldn't suspect it based on its effect profile, but you never know. 4-FA seems more likely to fit that bill, sadly :\
 
Seems there's a lot of fluctuation regarding dosing.

I'm looking to use this as a caffeine replacement - focus enhancer Saturday/Sunday mornings when I go play poker. So looking to use as a picker upper & improve focus , not looking to get high or euphoria as it seems 4-fa (which I've tried & liked) will be my go to substance for that , as far as the -fa/fma sereis is concerned (have 3-fa/2-fma on the way , will likely try 4-fma as well)

Would 15-2O MG be a good starting dose?

I tend to play 5-8 hours , and will take a dose right after I eat (at the card room) but am thinking if I plan to go over 4-5 hours maybe a small redose would be neccasarry.

I'd like to get away with using like 3Omg max a day, 2 days a week. Batch is the pink stuff raved about on here.
 
15-20mg should be a great starting point. IME 2-FMA is a very long lived stimulant. You shouldn't need to redose to keep motivated for 5 hours. Be careful, as you may want to anyway. Its not that the need to is there, but its so transparent, its easily justified to yourself. Like adderall.
 
Ok thanks for the reply.

Ill just refrain from having more then the initial dose on me when I go , so redose will be out of the question.

Will update thread with my opinion after my initial test (next Saturday). Will start with 15 and see where that takes me.
 
Still using small amounts of 2-FMA daily with no major problems to speak of. The jaw tension is pretty severe and often turns to headache, which is pretty annoying. Sleep quality has been shit but that's nothing new for me. Excellent functional stim if you don't abuse it.

Also, I was wondering how the fluoroamphetamines compare to prescription stuff like dexedrine or Adderall. I've never tried them so I have no reference point. How are they alike/different?

I find 2-fma very similar to Adderall, at low doses they are close to indistinguishable IMO. I've used a lot of both as well as meth & dex. However I'm not much of a dex fan; it lacks euphoria & feels dirty to me. I always feel this nagging sense of incompletion, I assume due to the lack of euphoria. I also crash from dex but not from other amphetamines. 15-20mg of 2-fma feels equivalent to 30-40mg Adderall, not a recreational dose but a pleasantly motivational, functional dose.

At higher, more recreational doses 2-fma feels a bit more euphoric than Adderall but not nearly as euphoric as meth, with a fewer side effects than meth but not as many as Adderall.

If I'm really tired I snort, oral use tends to put me to sleep sometimes at functional doses. This occurs with both Adderall & 2-fma but not meth or dex.
 
^ Thanks! So 2-FMA is more potent than Adderall on a mg basis, huh? Interesting!

I've tried meth once and didn't find it all that similar to any other stim I've used (except maybe Benzedrex). Have always wondered what the different prescription amphetamines feel like.

That's weird you find dex more "dirty" than Adderall. Always heard it was the other way around. Different strokes I guess!
 
Yep, I find 2-fma in between Adderall & meth in terms of potency by weight. For me at least.

I've encountered many people who prefer dex, in fact I think more people prefer it over Adderall than vice versa. And they do say they find Adderall dirty feeling, often. Strange how that works! Dex honestly feels like ephedrine to me, or maybe in between ephedrine & Adderall. I have a friend who prefers dex to Adderall but prefers 2-fma to both. He also prefers meth above all amphetamines.

Yep, I'm one of them. Racemic amph just lost it's shine for me. I feel too tweaked out, and my moods tend to swing a lot with racemic amph nowadays. Dex just makes me energetic, a bit euporic, without the downsides I experience from racemic amph. Just a clean fun high. I have actually bothered little with the fluoroamphs since I refound my love for d-amph.
 
Does anybody else feel like 2-fma stays in the body awhile? With adderall I can tell the next day I did a stim, but with 2-fma the effect is a lot more pronounced. I've had some friends agree and disagree with that statement.

BTW We like 20mg doses, never nasal or even sublingual. Combined with sunifiram/pramiracetam was a very nice combo where my thoughts were next to surreal, and of course..... wait for it... no crash! Unless you redose of course
 
Never tried Adderall but I agree that 2-FMA seems to "hang around" for a while. I find myself clenching my teeth after 8 hours of sleep. Maybe it's got something to do with the "meth" component? It doesn't feel like a nasty byproduct or anything, just lasts forever.
 
IME with 2-fma and prescription d-amp (dexedrine), l-amp (vyvanse) and mixed amp salts (adderall), 2-fma takes the blue ribbon as best functional stimulant because of it's smooth come-up, plateau and come-down and a less compulsive nature compared to the prescription amphetamines.

Prescription amphetamines, however, come with a considerable side-effect profile in my opinion, and just because 2-fma is the best among these doesn't make it totally benign. So far I prefer it to prescription amps, modafinil and 4-fa for productivity and studying purposes, but it still can take a toll on users if they aren't cautious.

Physical side-effects unique to 2-fma are kidney pains and a strange tightness in my lower legs. Psychological side-effects are primarily paranoia, obsessive-compulsive tendencies where none existed prior to 2-fma, and an inability to feel content after extended periods (5 days or more) of continued use regardless of dosage.
 
I figured I would make this post as I am not sure how many people have done as much 2-fma as me, anyway after plugging aprox 300-800mg at a time several times every 24 hours with small breaks here and there for a few months of my life (on top of heavy use before) I noticed some serious effects that methamphetamine on its own never produced (however I never quite used meth for as long I tended to go harder nd longer without food or sleep, I noticed meth never had much of a cross tolerance with 2-fma, however there is some for sure). On to the main side effects:

-Unable to smoke pot, hot knives resulted in blacking out and physical injury
-Extremely bad heart pains (also intensified by the fact my muscles were being eaten away from lack of nutrients) and cardiovascular flow, extreme pain that weed potentified 1000x even from one toke.

I would also like to note some effects that 4-fma managed to produce from only using 2 or so grams over 2 days with a break between these 2 days. Also at the time I had never used very many stims in my life and I had no tolerance, I would like to note all of the above effects are included on top of these:

-EXTREME light headedness and dizzyness I blacked out and fell injurying my back on a bath tub and blacked out a couple other times but i was careful after that. Even sitting down made me light headed.
-EXTREME Depression, nothing like anything I ever seen off a drug before except the one time I mixed a bunch of random rcs.

Some of the extremeness of these side effects may have been in hindsight contributed to the fact I didn't know how to use amphetamines at the time. I redosed very frequently despite ineffectiveness and took no attempt to preload, postload or prevent tolerance build up. But meth was definitely forgiving on harm reduction forgetfulness iMO.

Anyway I know these effects are for the most part in parallel to what amphetamines do to your body I would just like to note most likely 2-fma and DEFINATELY 4-fma are far worse for your body then meth, and that research should be done into these compounds into what the fuck they might be doing to our cardiovascular system and even brain that meth isnt.

Forgive my sentence structure im a recovering methaholic lol, I have also been up all night.. sober.. thankfully xD

300-800mg at a time

Whoa. Thanks for your input.

My typical dose hovers around 20-30 mg, so I can't fathom what 800 mg must be like. 2-FMA has some vasoconstrictive effects but doesn't fuck w/ my body temp as much as 4-FA. Real meth had far fewer noticeable side effects than any of the fluoroamphetamines for me, but we all know meth is neurotoxic as hell so "feelings" aren't always a great indicator of toxicity. (I've also heard that meth is much "smoother" than Adderall or other amphetamines in terms of side effects too).

My main hope is that 2-FMA is roughly as harmful as prescription stimulants like dexedrine or Adderall. We desperately need some human studies on this class of drugs since people (me included) are using them daily.

2-FMA is one of the few drugs I can combine with cannabis w/out freaking out lol. 800 mg might be a different story though ;)
