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

[intelligentmind]

This stuff is good in a pipe but leaves bit of residue. Harsh as a bitch when snorted!! or maybe i just got a different batch to everyone else

 

[casual44]

My friend has been trying this with various ROAs and combinations over the past week or so. He's got a lot of experience with various stims, including meth and many RCs. Here are some interesting points he told me.

- Plugging is definitely his favorite ROA (he's tried eating it, snorting it, and smoking it but he doesn't have a good pipe). Plugging gives a quick little rush that's followed by 2-4 hours of steady stimulation.

- For my friend, MPA seems to be much more euphoric when combined with alcohol. Without alcohol, he said it feels like there's "something" there but it's hard to quantify, and he general feels good, but when he's got a liquor buzz, then he feels incredible.

- Best dosage pattern discovered so far: alcohol regularly throughout the whole time, then 40mg plugged. At +1:30, 40mg plugged again. Then 10-25mg plugged every 1-4 hours for as long as he wants to go. It makes him feel light and energized with a nice body high. When he reaches a certain threshold, he gets really horny and sex is mind-blowing (on par with meth sex or so he says).

- Heart beat can get alarming (140bpm and higher!) after going with this pattern after many hours. This is the biggest drawback. If he's out partying, sometimes he needs to sit down and chill to bring himself down a bit.

- Pupil dilation is practically non-existent, even after as much as 300mg consumed (over 24 hours). His pupils blow up into HUGE saucers at the slightest hint of intoxication (we always throw sunglasses on him when we go out in public lol), making him look cracked out when doing almost anything, so the fact that this causes no dilation is a huge plus for him.

- He's prone to psychosis on most stims after prolonged use. But even after 24 hours of partying on MPA and alcohol, he said he wasn't getting any hallucinations or paranoid thoughts.

- His previous favorite RC was 4-FA. He tried combining the two and said it didn't really give anything extra, caused some hallucinations, and probably not worth the risk.

How long does it last

last about as long as dexamphetamine i reckon.

Agreed. I live on both and haven't noticed any difference between their active duration.

There's a possibility of hyperthermia.

And others might smell the foul smelling sweat which accompanies the MPA.
And others might see the shrivelled penis

I've been eye-balling small doses (5-10mg: I use it enough to know my margin of error isn't in the 10's of mgs ) 3-4x/day for the last 3 months or so in addition to dextroamphetamine of about 15mg as many times per day.

Hyperthermia: Definitely! Everyone at work complains about me and the air-conditioner.
Sweating: No-one has complained about that yet and I can't smell a difference but I notice I do sweat a lot more and coupled with the stim-induced mild paranoia, I use deoderant a lot...
Penile-obscurity: It's only noticable after 60+mg-days (work then weekend as well as other things) but I've to say I've never seen it smaller than since I've been using MPA. %)

In regards to harm-reduction, I haven't had any adverse health effects except very mild vasoconstriction (compared to other substituted cathinones) which is evident as pinkish fingers and feet as if they'd just been in warm water.

One exception was when I had at least 50mg (end of a long day and probably mis-judged) and in about 10 minutes, I got palpitations which scared the living daylights out of me as I'd never felt anything like it before and was sure it was an oncoming heart attack and it was the end for me. I crunched on some temazepam and tried to calm myself and in less than half an hour my heart stopped its wildest vibrations but worried me for the enxt few days as caffeine brought the feeling back mildly...

Just thought I'd chip in with some extended use data as I haven't read of too many others gunning for MPA as long as I have - it's the most functional designer sub. I've found.

MPA is really cool when combined with alcohol. I've also noticed that when mixed, there is no hangover in the morning. Some slight anxiety, but no hangover, which is great.

I just ordered a few more grams of this stuff. Way better than ethylphenidate, which was a waste of money.

40 - 50 mg of this plugged can't be beat.

 

[intelligentmind]

in interest of harm reduction seeing as this is an RC & nothing is known about long term effects would a better alternative to smoking be oral as it smokes up but tastes like plastic which is sort of a concern. Would there be much of a cross tolerance with this stuff & 6-APB?

 

[BloodTranceFusion]

Same on both counts! Tried ethylphenidate as did someone else (same and only batch we've tried) and noticed nothing at all without wanting to take multi-100's of mgs. Left the rest alone as I don't appreciate methylphenidate and read they're akin.

I'm shocked MPA isn't more popular given the similarity to other things but; different strokes. I don't use it to get my rocks off but to get things done. I'm not upset that it isn't getting legal attention (after MDPV). I'd be up a certain creek without this.

as this is an RC & nothing is known about long term effects...

I'm still alive after 3 months of mild, functional -not recreational - usage, if that counts. I haven't really seen any accounts after a week or so of smeone getting their hands on it.

Would there be much of a cross tolerance with this stuff & 6-APB?

I'm not sure if anyone can answer that authoratitively (tried the Adv.DD forum?) but I guessed "yes" from the structure of 6-APB on Wikipedia. The #pharmacology section surmises as much, despite the differences in their subjective effects.

Although I've only dosed orally a handful of times, it seems to work well that way. My only concern is I suffered some urinary tract irritation a couple of times, feeling the need to pee when my bladder was actually almost empty. It may have been coincidence, though, and I'd been drinking beer at the same time.

That's quite a common side effect that happens with most stims, I one for get that from practically ever stim ive tried. Its like I have a water infection which disappears after the stims have worn off.

 

[BloodTranceFusion]

until it hits? How does it compare to other ROA?

I notice I piss less forcefully than usual so it sounds like Im going like a horse, for ages, when my bladder's probably far less capacitous than usual. Just FYI, if anyone wants details.... X-D

Dex., anhydrous caffeine, MPA and alcohol at the end gives serious bladder instability.

Anybody encountered this stuff being sold as mephedrone in the UK?

 

[Coveman]

No, not ever.

 

[FlyinHigh82]

After a really long week with lots of travelling and little sleep, just plugged 50 mg. Snorted whatever left was left in the bag. Feeling energized and a great body high now.

I hope my next order comes in soon, cuz I'm all out.

This stuff is great.

Awesome that "the man" seems to be more interested in other things, and it isn't drawing more attention, like MDPV, which drove some people insane.

This is deffo the best RC stim out there, hands down.

Edit: a small, 10mg line of ethylphenidate whilst on this is quite nice!

Edit again: A bit of ethylphenidate (a very small line) insufflated on top of MPA is really nice and euphoric. Two hours in and still going strong, feeling great, relaxed, and horny as hell. No urge to redose either, whereas with MPA I'd be debating whether to plug another dose and how much. So glad I found a use for that ethylphenidate I bought.

 

[intelligentmind]

Will someone feel the effects if their on an antipsychotic?

 

[Transform]

Yes, depending on which antipsychotic though effects may be reduced. Antipsych tend to be serotonergic whereas this is firmly dopaminergic.

 

[foolsgold]

did not like this stuff much when it first came out now i cant get enuff its morish as hell

 

[intelligentmind]

Yes, depending on which antipsychotic though effects may be reduced. Antipsych tend to be serotonergic whereas this is firmly dopaminergic.

Zyprexa dose is 5mg

 

[blakmike]

Someone give me their opinions on average joe's preference of buzz, MPA or 4FA. Also which is less toxic (all systems of body) and which is cheaper usually (buzz per $wize)?

thanx mike

did not like this stuff much when it first came out now i cant get enuff its morish as hell

anyone else agree with morishness?
nothing on the level of coke, ethylphenidate, pyrillodines, right?

THanks,
Mike

Mike

have you read the threads for both chemicals? they are very different - 4-fa is quite euphoric and MPA is functional only, very little euphoria there. both are RCs, so hard to say about toxicity... check vendor prices and usual doses and you can do your math which one is cheaper per dose.

 

[Blake7]

Yes, depending on which antipsychotic though effects may be reduced. Antipsych tend to be serotonergic whereas this is firmly dopaminergic.

FWIW, my only experience is with risperidone. It's action in mostly dopaminergic, acting on the D2 receptor apparently but has only a mild seritonergic action. I'm not sure how this would affect MPA though.

right im not to sure if iv been getting it cut with something else or just been very very lucky of late with it but yes its morish lots more than ethylphenidate which iv found nice but nothing on these lines . i believe its been cut with 2ia at the minute but thats just a guess at best
