Welcome to the MPA Megathread. This is the place to discuss all things MPA. MPA is a thiophene ring-based structural analog of methamphetamine (methylamphetamine, m-amphetamine, crank, meth, etc)

Some of the last posts from version 1

Yes, please do.

By the way MPA and pryazolam is pretty nice combined. As pryazolam is much less sedating.

To those who are vaping - anyone ever try a pinch of baking soda to see if it improves things at all?

I'm thinking of trying this one out. I have a lot of experience with mdpv and apvp. I'm looking for something more productive and not as crazy morish and rushy as PV chems.

And someone said mpa vapor tastes like plastic? Is it harsh?

Does vaping have a definable rush?

I ate 50mg 6 hours ago, and I've been smoking MAM-2201 throughout. I feel pretty epic right now. I didn't get the come up shit that I got with ethylphenidate, and no jitters either.

Tastes revolting.

Revolting? That doesn't sound promising.

I'm kind of wary to touch this stuff due to the formation of sulfur oxides. Read a study where they tested thiophene and found it's metabolites to be toxic to cells in the cerebellum. Another study seemed to confirm that the thiophene in mpa is metabolized and therefore is certainly a toxin.

Sure would suck ass if this stuff causes problems down the road.

Tried it, didn't like it. Some minor stimulation (kinda like caffeine or something). Either I didn't take enough (60mg), used the wrong ROA (oral, and yes, it's a bit disgusting) or got scammed (reputable vendor, but you never know). As far as I'm concerned eph > mpa, but then you have a lot of people saying the opposite. Guess it's an individual thing.

I just got my hands on some 2-AI. It feels like a dopey amphetamine.

Is there anything out there at the moment that increases libido as much as MDPV did when it was around? The fuck sessions i had when that stuff was legal were insane, i miss them!

The other day I tried some methiopropamine. My god that was the most disgusting thing I ever put in my body. I really regret it now. I'm a hardened drug user in some ways, especially with stimulants. This stuff left me shaking for hours and hours after it wore off. I couldn't eat or sleep for 2 days and nights. And a very sickly feeling all about. Taken orally. Never EVER again.

 

[adam west]

eph is better value for money and btter quality imo

 

[DJ_Cosmo]

Agreed. While ethylphenidate usually gives me trouble sleeping it feels rather clean (if sometimes a little jittery). Very powerful mindset too. EPH I'm a confirmed fan. MPA is complete junk.

 

[adam west]

well you can be a bit more reckless with mpa, more forgiving in that respect

 

[lynx2051]

MPA feels very filthy.

 

[foolsgold]

so whats the view on the new type of mpa ? is it any stronger easier to vape ?

 

[crazycatman]

totally agree with the above posters

eph is good, mpa not so much

2-fma puts them all to shame.

Shame it's pretty nonexistant here as of late.

 

[stardust.hero]

If 2-fma can put it to shame, I don't even want to imagine what MPA could possibly be like.

 

[lynx2051]

2-AI is pretty good, if anyone is looking for a clean stimulant.

 

[foolsgold]

^^i found that stuff very jittery no mater how its taken

From previous topic:

Ive found that after 3 or 4 days use of MPA at around 100mgs that you hit the ceiling and no matter how much you take it just doesn't work anymore. It forces you to detox for a few days.

Although unfortunately it doesn't stop the vasoconstriction and load on the heart from worsening (due to the accumulative effect) so I'd advise everyone to stop immediately and take a good break as soon as you realise you've hit this point. It's the point at which you're quite likely to push yourself over the edge and into the next life.

By the by, this stuff is scarily easy to use on a daily basis. As long as you're not using it in quantities where it really interferes with sleep and you're getting a good 8-10 hours (factoring in some extra brain recovery time there) then you can easily use it for weeks on end. Don't though.

I've said this so many times but does anyone else think that MPA tastes absolutely revolting?

It really does. It's vile!

Most drugs taste disgusting until you get used to them. MDMA terrible bitter. Even alcohol isn't much cop

That's pretty true, especially of powdered, synthetic types. Although I've used MPA quite a lot and never really adjusted to how bad it tastes!

How does this compare to ethylphenidate low doses? Is this a good study aide? I dont like adderall because it hardly works anymore... Is it more like adderall?

Not really, no. There's a few posts towards the back of the last megathread involving discussion about how MPA is actually a very dirty drug. Not a recommended study aide at all. Whilst I personally don't think much of ethylphenidate (EPH), you'd probably have a lot more luck with it than this because it's considerably cleaner but requires a little more respect to avoid going on a bad one. EPH is kinda like cocaine in that it produces a feeling of "I can do anything, fuck everyone who isn't me" so pretty good for studying, not great for socialising (well, not great for everyone who isn't you )

I'm kind of wary to touch this stuff due to the formation of sulfur oxides. Read a study where they tested thiophene and found it's metabolites to be toxic to cells in the cerebellum. Another study seemed to confirm that the thiophene in mpa is metabolized and therefore is certainly a toxin.

Are you talking about vaping specifically? If this is a general warning about every ROA then I've got some serious thinking to do.

 

[lynx2051]

I wonder why MPA is such a strong vasoconstrictor?

I should have read up on this chemical more before ingestion. I didn't realize that vaporizing it produces sulfur oxide/dioxide... It's a little late now.. Apparently sulfur oxides are toxic to the point that they can kill you at relatively low concentrations. I've vaped about 4 grams of it over the last 6 weeks. Very silly of me, but I don't want to be lectured.

Can anyone take a guess at what kind of long term and short term side effects I'm going to experience? I'm wondering whether or not I should go to a doctor. I've already got a sore throat and what I assumed was just a cold. I'm thinking more along the lines of lung infection and irritated throat/mucus membranes now. My voice has also deepened and is quite gruff.Apparently sulfur oxides are toxic to the point that they can kill you at relatively low concentrations.

I did some calculations, but i'm no chemist so they are a bit shoddy.

I think there is about 174 mg of sulfur total in the 4 grams i've ingested. This averages out to 3.86 mg a day over the space of six weeks. I tried to calculate how much sulfur dioxide i've inhaled but I got a bit confused by the PPM side of things..

If anyone with better knowledge of the field could help me out, please chime in. Also if anyone can suggest anything that might minimize the damage i've already caused (vaporizing something else eg. water?) that would be greatly appreciated.

I've stopped consumption and I'm going to do a hell of a lot more research before i start vaping strange chemicals again.

 

[foolsgold]

i must be the only person still liking this stuff strange because at first i was not to keen but i like the fact im not up for 6 days straight because iv binged with it il like how i get bored n want to come down guess thats why iv just got 5g of the stuff for christmas

Definitely go see a doctor, mate. Don't take chances, your long-term health isn't worth it. Even if it only tells you the results of what you've done, at least you'll know.

Not gonna lecture you though cos most of us on here will have been wide awake at 4am making desperate pleas to our various gods to survive through the night at one point or another. I'm an atheist and even I've done something similar with whoever might be listening (the first and last time I ever took mephedrone comes to mind).

just one thing it may seem like common sense but keep hydrated with this stuff its so easy to forget and you don't need those nasty kidney pains that go with it
