RCs The Methiopropamine N-methyl-1-(thiophen-2-yl)propan-2-amine (MPA) Megathread

(Sorry for my english, my English is average)



Male, 100kg (sports, big guy) Mainly experienced with methamphetamine, amphetamine, etylophenidate, ethkatons.

I am surprised that you such small doses.

10 p.m. - 150 mg snorted + 200mg ethcatone - great euphoria, better perception of music, something beautiful. 3-4 hours, and slow 1-1,5 hours.

Generally very strong performance for the first time, the next weaker, but equally good.

That's quite a high dose, I am currently on 20mg and it is a little mild but pleasant. 30mg oral is probably the best for me. This is the only chemical I wont snort, the smell is awful and it burns like Meph, at least Meph didn't taste so bad.
 
I'm using MPA for 'motivational' reasons, however it hasn't worked that well. For simple things like sorting stuff yes... But making stuff/thinking it seems to be too 'speedy'.
I have tried really really small doses all the way up to larger ones, orally and insufflated. At first it's the 'rush' for a hour or so and then just leaves me a bit tired/jittery/'stimulated' for a few more hours. Can anyone tell me how UK street speed compares (for 'study' reasons).

I also can sleep on them if I want to (I even tried taking some and going straight for a nap), I just don't usually feel like sleeping. (Read this earlier on somewhere).
 
Just signed up cus I got a gram of mpa andmdai.
Moaning can be used IV. I did 30mg and ate 200mg of mdai. The rush felt like your average IV stim rush. Very nice...but there's a crave.
I developed a headace as the mdai hit me. A few aspirin took care of it. I like this. Nice even mda-like roll. Though next time ill justbomb the mpa orally.
 
I've noticed the FDA in US have approved a prescripion form of Methamphetamine known as Desoxyn, which to my knowledge so far comes in 5mg and 10mg. It's used to treat ADHD and a certain type of Obesity, Certain people have called it Adderall without the side-effects. Online it looks like it's available at $200 for 240 I wonder how this would work as a substitute for those who don't like nose-candy.
 
I've been hearing a lot of mixed emotions about MPA and reading here seems to be the same. I'm not sure if it is just people ordering from poor quality suppliers or different tolerances but after trying MPA on several occasions and situations I can firmly say this is one of the most enjoyable chemicals I have ever tried. Having 'tried' (In copious amounts) quite a number of your typical and research chemical I find MPA to be the right balance between stimulation and euphoria.

That being said, I do have to admit this chemical has given me the worst effects side ever on a mixed drug experience. Having mixed it with 30mg of aMT (which we have taken on it's own and been fine) with a friend we both became unable to stand without extreme dizziness to the point I collapsed on my couch and also blacked out hitting my head on my elevator door. We also suffered from heavy sweating cycling between warm/cold, auditory disturbances when dizzy (hissing noise) and our hearts pounding so hard you could watch it through our clothing. However this of course could all be attributed toward the aMT (which in sure others have found an 'experience'). A final point to add is this stuff is defiantly highly addictive. People often go on about how addictive things like opiates, coke, smoking, drinking etc. all are and fully understand how 'moreish' certain drugs can be. However, I personally find it very easy to binge on any substance and never strongly crave it again but unlike any other chemical I find myself constantly wanting to just have a small taste of MPA to make everything seem better.
 
I re-allergy tested this a week after getting it and nothing happened so I realised I could take it after all.

Will parrot what many others have said: this is purely a functional stim; at most it just increases enjoyment of general things (e.g. the amphetamine acid test: tidying up). It could keep you up all hours though, that's for sure.

Euphoria slim to none and social effects were counterproductive, in my experience. I found that with a moderately high dose I loved myself but absolutely hated everyone else (sometimes happens to me with dopaminergic stims though).

I actually pine for the days of BZP where at least the basic pharmacology was understood (and I just loved BZP but that's a different issue). These new chemicals with a wikipedia article shorter than my dick and no known mechanism of action make me decidedly uneasy. I don't think the RC market being legislated out of existence would be the worst thing to ever happen. So far the only truly awful experience I've had was accidentally ingesting 1g of mephedrone in 2 hours with no tolerance and that was all on me but I constantly feel like it's only a matter of time (bromo-dragonfly or NRG-1 part II).

Those adverse effects can affect a person without needing to mix with aMT. The aMT can't have helped though. I'd steer well clear of mixing MPA with any other stimulant.
 
Where, exactly?

Face, back, chest, penis, i got this weird lump smaller than a pea on the shaft of my dick that had pus in it, :X, my cousin got these smaller pimples on his chest after using rc's with me for the first time, and my other mate who goes real hard on MPA all of a sudden breaks out with these 2 fucking huge boils on his face, if anyones had anything like these please say
 
I haven't heard of that before. Sounds impure and/or not MPA. :(

Anyone else experienced their sense of taste going a bit off after a night of MPA/MDAI use? It makes cigarettes taste really weird! No clue what it could be.

If you were snorting it, were you sharing a note/tube/snorting tool? One of you could have had something and passed it on to the others.
(In my completely uneducated opinion)

I must say MPA has been very addictive lately. I've been parachuting eyeballed dosages every other day or every other 2 days for the past weeks now, sometimes staying up in excess of 24 hours. In my opinion 'moreish' is an understatement, but then this may be pure personality; I generally find that after the initial rush is gone, I want more of something that wasn't really there to begin with. Then when I realize it's no use going to sleep in the early morning hours, I will decide to keep going until evening comes. Since few others have reported any such effect, I will chalk this up to me being used to cocaine and chasing a high of sorts.

Weight loss and excessive sleep (duh!) were noted.

Those sound like pretty severe side-effects, would not touch that batch/vendor again! I have had none of the symptoms you describe, I can't imagine them being MPA related, but with RC's I suppose nothing can be ruled out.. Yikes.


One more thing; as was commented before, I do find taste is affected in a weird way, even when parachuted! Cigarettes do not taste like cigarettes at all indeed, and wine or other drinks taste 'off' as well. Generally a familiar, slightly foul taste will manifest in my mouth after a number of hours, although this might be simply related to dehydration.

Will probably not use again, since its initial usefulness as functional stim seems to be negated by my tendency to binge. To me this seems like a rather personal flaw in thinking where I confuse MPA's stimulation with a high that ought to be enjoyed and prolonged.

However I will maintain it is excellent for getting mildly complicated chores done; grinding and boring tasks are done with dedication and precision, and things generally can be accomplished (as one would expect from amphetamines). For more subtle or rather cerebral tasks (reading long texts, writing) it did not seem to be very helpful; the prospect of just reading a text seems like a waste of time, and there was a certain tendency to unnecessarily explore and research concepts not pertinent to the tasks at hand. Again this may be attributable to the false perception of experiencing a high rather than plain stimulation.
 
taking since a week everyday about 200mg mpa 200mg mdai and 200mg tramadol daily
(give a shit about my future !!!! thats to say about the risk i am taking )
the mpa I do vaporize .
i was a meth and opium smoker in iran. it is common in asia to smoke meth!
mpa melt and smells similiar. but while good meth almost vaporize into nothing, mpa always turn brown in the end,leaving a burned rest ,
how toxic is that?
does it come from the sulfid?
or does it have a lower point of vaporizing?
( smoke it in a broken light bulb because no watericepipe here available )
the first days , my lungs felt shit , so i started it to smoke very carefull with a very small fire.

like many people wrote here in this tread , just mpa had a lack of happy feelings ,unlike meth.
with small bombs of mdai, i had all what i missed
i been a super talkative superhero ,
the tramadol helps for the comedown, when the depressions starts!
similar to many coke and meth- heroin addics

i stayed awake for almost 60 hours and going to work was no problem .
usualy i am tweaking after 2 -3 days with a lack of sleep.
. in iran there are a lot of regulary methsmokers, but the most fall pysically and psycic apart after a few years .
so lets check what will happen to me after mpa ,mdai use for few weeks?
this combination is at least or almost the same addictive as meth.

heardbeat, insomania, sweating, cold hands, lack of hunger ...... same,
the first days i had 3-4 50mg each mpa and mdaibombs dosises a day
got light cramps in my hands but it vanished after
use a lot of calcium,magnesium and b-complex and aspirin......or mabey it was just the exercise?
what i realize own my self, now after a few days,i becoming less greedy to it ,just start to smoke and use less of it.
because my bodyfunction warns me?... do not know
on meth i use to smoke even more the longer i am taking it.
I still behave in a non social disbehavior ,
unlike meth where i am always escape after a few weeks, to force a break.
because of paranoia and losing selfconfidence .... lost most social contacts....
mabey it will come later lets see.
i just can warn anybody who still has hope in his life expectations to use it regulary!!!!!!
.....inshallah will write back again

Oh good, so I'm not about to have a stroke. That's exactly what happens with me as well. Certainly one of the nastiest side-effects I've had from this stuff but I don't get stimulant comedowns (not always an advantage when it comes to controlling usage). That said, it can't be dehydration because I have a very strict food and water rota when on stimulants. Overall, I'm not really complaining that this has made me indirectly quit smoking. Historically this will probably go down as a massive plus for MPA.

Will probably not use again, since its initial usefulness as functional stim seems to be negated by my tendency to binge. To me this seems like a rather personal flaw in thinking where I confuse MPA's stimulation with a high that ought to be enjoyed and prolonged.
Definitely, man. I'll think twice before ordering again because, left to my natural urges, I would go on week-long benders with it. The fact that I actually get a little accompanying euphoria and overall "good feeling" has a lot to do with it; that and its match with MDAI was made in heaven. The worst side-effect in that combination then becomes strong nausea for me though: helping but hindering.

5-APB (200mg) + MPA (300mg) + MDAI (200mg) - I wont' bother with a full report but I will say I had no ill effects. Heart rate, BP and head all fine. Feeling: Fucking incredible. More detail if requested
Gravedigging a bit but those doses are fucking heroic for that combination. Bit skeptical that anyone could do that and get away without either serotonin syndrome or a few days bed-bound afterwards.
 
Does anyone have any experience with taking MPA and aMT at roughly the same time? They seem to have a strongly synergistic effect, a 20mg dose of aMT I took today was way stronger, and far more euphoric than any time I've done aMT in the past, and I've taken doses of upto 60-80mg of aMT. I had taken around 120-150mg of MPA orally earlier (I have a very high tolerance to MPA as I use it very frequently). This is virtually indistinguishable from 120-150mg of MDMA! That really surprises me as up until today I thought aMT was very subtle (and was thinking around 80mg for my next dose - I've revised that down a lot!!! 8o)...
 
I follow the "never mix stimulants" rule of thumb. If it works well for you, fair play, but I'd experiment with other MPA combos to bring in the same serotonergic and psychedelic elements added by the AMT.
 
Put it this way, I'm glad I only did 20mg of aMT - much higher would have been overwhelming!
Yeah, haven't personally tried it and probably won't but I've heard big things about that combo -- both good and bad! Seems okay if you choose the right doses but just be careful with it :)
