RCs The Methiopropamine N-methyl-1-(thiophen-2-yl)propan-2-amine (MPA) Megathread V2

now have a batch of MPA, and am about reading sinus irritation?
can we related the troubles of nasal EPH and MPA ?

truth is iv given up on trying to get a doctor to take me seriously because i know that on my medical records they have put drug seeking so im sort of fucked no matter where i go

Not much, about 130mg over 8 hours taken orally, but I am a bit forgetful anyway. It only started happening when I was first prescribed Citalopram, never had it before when I wasn't on SSRI's. It happens more on the comedown when you're just left with the stimulation. Just to add it's really easy to eat on MPA even though you don't even think of food, it doesn't make eating difficult like a lot of stimulants.

I've found that guanfacine tends to help with memory issues, a welcome side benefit since my main rationale was to lessen stress on my heart / blood pressure etc. The effect is a little subtle, but working memory is definitely enhanced, as is the ability to resist hyperfocusing on some stupid distraction that consumes hours of your time trying to be productive...

I don't think guanfacine is prescribed here in the UK, not that I could get a prescription for it anyway.

The massive day-long obsessions with doing something completely pointless and unnecessary is seriously annoying though. Without stimulants, I'm terminally lazy and with stimulants I'm too focused on the wrong things. You can't win really.

Sinus irritation is somewhat a given when you put powders up your nose i guess, not to mention I'm genetically fucked when it comes to sinuses both my parents have had issues with their sinuses/trigeminal nerve and their parents and so on and so forth so it might be more that than the MPA
 
As I understand it, MPA is kinder on the nose than EPH (still not good for it though). Based on how corrosive EPH seems to be, even when just handled for a while without washing it off, it doesn't seem like the kinda thing you really want to shove up your nose.

MPA probably isn't much worse than the "average" drug but we all know that snorting too much of the average drug isn't a great long-term plan anyway!

Note: I'm somewhat biased against insufflating drugs. I actively encourage people to only use orally because it very rarely has any ROA-related risks attached and it seems to be less habit forming than insufflating, smoking or IVing.

Does this mean EPH burns the skin on your hands or have i misread ? I just ordered some along with some MPA to see if it lives up to what i've heard but if its burning relatively thick skin on the fingers and palms i definitely won't be putting it anywhere near my nose.

Exactly, yeah. I've heard reports about it and experienced it myself, to some extent. Most people recommend against snorting it for that reason!

I have to warn you that you probably won't enjoy it very much. There's an interesting dichotomy between MPA and EPH. My collation of a lot of different opinions on the subject has led me to believe that very few people enjoy both. The majority of fans of one are diametrically opposed to the other. It's fascinating really!

Edit: on an unrelated note, I'm completely off the MPA for today and I feel like my IQ has gone up a good 20 points as a result. It really isn't an intellectual stimulant at all. I'm currently studying for a masters in computer science so this discovery is going to have serious implications for my work ethic in future.

super fluffy sticky stuff..
5mg allergy bump no burn
15mg test run - slight burn different then eph
and here we go.. work in an hour get a few bumps in before then

edit: just cleaned my room, this is pretty clean so far
definitely sweaty and hot headed, feel effects on my blood circulation

eph strikes me right away as being more recreational
i'd like to add a bump of eph @40mg mpa nasally

i like the sweet and chemically taste though over eph

this is extremely meh,
although I constantly crave lines
I'm @60mg just feel flat with slight clean stimness

But I'd bet going up stairs will have my heart bumping

Cross tolerance with eph? I also used methylone the other night with lackluster effects due to daily eph use I guess? Sorry on phone

Nope, that's MPA for you. I recommend oral dosing.

Does anyone else find themselves burping a lot on MPA?

Fair enough mate. What are you basing that on though?

I really don't think MPA does you any favours in terms of raw, logical processing power. I've come to that conclusion from my experiences doing maths exercises on and off MPA. I also think it negatively effects organisational clarity and comprehension of complex concepts because I'm noticeably worse at understanding difficult parts of my course when I'm on it (constructing LALR(1) shift-reduce parsers for any of my fellow MPA-inclined computer scientists who may be out there!)
 
I haven't had any of this for just over a year, after using it weekly (sometimes daily) for the better part of a year.
I found it way too habit forming, and the smell was too much.
And the vasoconstriction.
And the jaw clenching

Urgh...this stuff is bad news. Any reports of hospitalisations/deaths from it yet? Or long term health issues?
 
I had six months without taking this and had a few lines at the weekend. I'd forgotten how bad the urinary retention due to vasoconstriction could be. I seem to suffer this far more than any of my friends and by the end of the session it becomes extremely uncomfortable, especially as a few beers tend to be consumed over the evening. I don't get such bad effects from any other stimulant, it is in a league of its own. Can anybody recommend anything to reduce these effects?

I wonder if cross tolerance plays a part in this, i did the usual unfamiliar RC thing with this EPH- small test to make sure nothing untoward happened and it didn't so i tried a greater amount insufflated and then a few days later a fairly substantial IV dose of EPH dissolved in propylene glycol and water, it refused to dissolve otherwise but maybe I'm just impatient and anti stirring and still very few big effects.

A bit of stim jitteriness in my stomach (kinda like feeling nervous? i'm sure you know what i mean) and a bit of vasoconstriction but no rush or euphoria or even any desire to do anything. I mostly just feel a bit sick and a pretty annoying rise in body temperature.

Whether the lack of euphoria was to do with pretty heavy AMT session that I endured this weekend, i say endured because hallucinogens do not agree with my brain and thus i'm still rebuilding any of the monoamines i used up over the weekend or not but either way I prefer MPA over EPH unless i'm missing some sort of game changing ROA for EPH

I'm yet to hear of any serious adverse events from MPA use which don't mention interactions or the general effects of long term use of stims, theres been a few mentions in this and the previous megathread of a bit of psychosis if its used irresponsibly and I read somewhere, can't remember where, that someone went to the emergency room following a weekend of binging on MPA and MDPV but after some symptomatic treatment (I'd imagine benzo and vital monitoring) were ok.

As for long term there has been some musings of cardiac issues relating to serotonin agonism but there is no literature to back that up with. Other than that i'd say its again just the usual long term stimulant issues that arise from vasoconstriction and increased heart rate/blood pressure.

I had six months without taking this and had a few lines at the weekend. I'd forgotten how bad the urinary retention due to vasoconstriction could be. I seem to suffer this far more than any of my friends and by the end of the session it becomes extremely uncomfortable, especially as a few beers tend to be consumed over the evening. I don't get such bad effects from any other stimulant, it is in a league of its own. Can anybody recommend anything to reduce these effects?

This seems to be a very subjective symptom, MPA if anything leads to me urinating more often and very rarely makes it difficult, the lack of research into stimulant induced urinary retention is most likely due to the fact most peoples response is "stop taking stimulants". MDMA leaves me pretty much unable to pee and i've found that pushing or trying to force urine out is counterproductive, try taking a deep breath and relaxing to let it flow out instead of getting annoyed or trying to force it.

Alpha blockers have shown some promise in helping with urinary retention but usually with other primary causes, plus as far as i know they are prescription only but there are some plants and supplements out there that do the same general thing.

As a little after note in the interest of looking out for people it may be worth mentioning it to a GP with or without saying its stimulant induced so they can check theres nothing else that might be lurking under the surface that is merely being exacerbated by the stimulant use.

Anyone tried the brown stuff? seems impure but produces excellent effects...

Brown MPA!? obviously not asking for vendor info but did they say anything about why its brown? also where are you getting it from geographically ? Brown MPA sounds shifty at best.

It really isn't an intellectual stimulant at all.

Hmm, I have to disagree.

Well nothing like a bit of disagreement to stir up debate :)

I guess the cognitive effects of a drug are going to vary pretty dramatically by the nature of how different brains are from each other. Personally i've found taking MPA for a lengthy period does leave me a little bit mentally slow, thats not to say i'm incapable of studying but simpler things like word recall and working out pretty easy maths seems harder and more laboured whereas my focus on things is improved.

I'll happily write a 1500 word essay on something unrelated to my actual studies even if it requires no mental power at all but when it comes to the task of actually using my brain to write about something mentally challenging such as my current actual study for my degree my brain seems to be lagging behind and wikipedia is much more heavily relied upon (checking the references of course:)
so i guess i will have to agree with Machete that as a motivating tool its very useful and if you already have all the information in your head and only have a limited amount of time to write it up (as i found when i forgot about an essay until the night before) then MPA has its uses, read: makes you type like a cracked out secretary.

But for actually challenging mental situations it seems like it slows you down more than anything, i certainly wouldn't risk it for an exam or inspection or any other time limited high stress cognitively trying situations.

Again just personal experience, i also tend to get a bit moody on MPA and have very little time for people who are doing things wrong so maybe its to do with patience and cognitive function... you may be able to tell this isn't my area of expertise (yet) but at least I'm trying :) . Anyway i will stop flooding this page now, i should probably start replying to several posts in one reply :/

US, so probably comes from asia

Yeah I agree with those side effects. But there's no anxiety or paranoia like with most stimulants. EPH feels like it try's to be a stimulant when it isn't stimulating at all. EPH used to give me breathing difficulties sometimes.

One more bad thing with MPA is the insomnia. The other day I took 35mg repeted 3 times (105mg) up until 4:30PM and I never slept until 6AM! :X

That was the very first time I'd never taken an etizolam or any sort of downer. I think with a lot of stimulants you get that too.

I suffer terribly with insomnia (pre-dating my stimulant usage) and i find that not taking MPA after about 1pm usually gives me enough time to get back to near enough baseline for sleep to be an option. Downers help a lot obviously but i prefer to not have two drugs fighting each other in my body while im trying to sleep, psychosomatic i know but nonetheless i prefer it.

Just thought I'd mention that i had to have a liver function test a few days ago before starting some different meds for sleep and anxiety, they came back slightly abnormal which I put down to aMT (feels pretty harsh on the body) but according to my GP well within the acceptable safe range, given that my MPA usage is pretty heavy and over a long period of time (although i didnt have any for the 3 days before hand) i'd argue that if MPA is hepatatoxic then it isn't damaging to an extreme amount.

Obviously different people react differently to things and I very rarely drink alcohol (if i do i almost never get hugely drunk) so that will have some bearing on liver function but i just thought this might be a useful bit of information.

In other news I decided to make use of my uni's chemical cupboard and performed a basic acidified K2Cr2O7 redox test on vaporised (burnt?) MPA by heating it (MoSi2 element limited to 500ºc for those who are interested) in a sealed container and pushing air (along with the MPA smoke) through tubing and bubbling it through the K2Cr2O7 solution. After vaporising 900mg and pushing it through at a rate of 2.5L/ps the solution began to turn green indicating the presence of sulphur dioxide.

As a note on that test I'm aware that any number of reducing agents could cause the solution to change and this isn't a definitive test for sulphur oxides but at least its a little better than anecdotal. I'm not a fan of smoking any kind of chemical (tobacco and weed aside) and especially not MPA given its foul taste so I'm not sure of the amounts people go through or the actual ppm of SO2 it produces. I hope to test the ppm at some point but the uni is a little wary of people using their gas analyser and I have a feeling if I tell them what its testing they will probably say no but fingers crossed.

Sorry for the lengthy and mostly dull post

Fluffy, white, clumpy powder. Clings to the plastic bag. Not as easy to handle as powdery/sandy chems. Reminds me of 5-MEO-DALT with regards to texture.
30mg oral gelcap, empty stomach.
10mins in, slight jaw tension, heart rate up, stim. feeling.
Probably experiencing cross tolerance due to use of other stim RCs like Eph, the APBs, 4FA, etc.

2 hours later, nothing but a slight chest tightness. A 50mg dose will probably give a much strong stim, but I wonder about the jaw/chest/stomach discomfort & how that might amplify. The only thing I like so far is the lowe dose needed (compared to 100mgs of most other stuff).

Feedback welcome.

confirmed the batch i have could be described similarly to my dalt batch awhile back.


all i can say is, I don't find this recreational
but it did allow me to stay up two nights straight
without food or water in jail

only have used nasal roa

i think there is cross tolerance, and certain rcs are capable of increasing tolerance drastically through potency on our receptors
had some slight chest pains after 2 days, and when i got home went for the eph, much more satisfying
