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

Chronic/heavy Methiopropamine (MPA) users, please post your experiences

I have been (ab)using MPA for a couple of months now and I have written posts and replies on my usage. I am starting this thread in hopes of finding out as much about this chemical as I can.

My other MPA posts (if interested):

I am interested in any studies or mentions of MPA in the scientific literature, as well as anyone who knows a thing or two about "thiophene ring-based structural analogs" (of which MPA is to meth.) If you can just infer anything about MPA, neurotoxicity, long term damage, dosage, side effects, etc from your knowledge of chemistry or experience with the drug or related drugs (meth or thiophene-ring based drugs not related to meth), I would be grateful.

The fact that MPA is not a fun drug means it will never reach an epidemic that will catch support from the scientific community. MDPV and Mephedrone grew a fan base big enough to make the headlines. MPA will just be labeled meth and swept under some new law before disappearing from the gray market. This still leaves us MPA users in the dust about what we're doing to ourselves.

I have a hunch that vendors unable to sell 'pure' MPA are beginning to cut it or offer it in different forms (from another thread, ... "Its become available in capsule form, containing what is IMO a bloody stupid quantity, pink panthers, with 300mg per capsule, although one cap only per package. Rediculously cheap.") The price is low because it's not popular, and shelf space is high. But for the sake of this thread let's assume that we're talking about relatively pure MPA ingestion and its effects.

What color/consistency has your MPA been?

What country did it come from?

Have you received different looking batches, or had different experiences on the same batch?

Does it have a strong odor?

How bad is the burn when insufflated? How long does it last?

What is your average dose or typical pattern of usage?

I'll answer these questions myself (I have answered some in the threads above) but any info you can give would help. I'm especially talking to daily users or people who take it in massive doses. I will continue to update this thread as I gain more knowledge on the subject.
 
My vendor has verified that there are different batches going around. This might explain why some people take 300 mg and others take 30 mg, why some people think MPA is complete garbage and others think it's amazing, why some people say it burns like hell and others say it only stings a little bit. I can't say anymore about the batches and I don't know what the differences are (whether one is impure or contaminated, or is a completely different compound.)

At the moment, I have a batch of supposed MPA. I've taken doses of 300-600 mg with zero effects. I had never taken more than 150 mg spaced over 24 hours with other batches. Even at 600 mg within 2-3 hours, I had no sign of any stimulant activity, no crash of any sort, and it gave me a small nosebleed. It was a small spot of blood but enough to cause me concern. I've taken the prior batch of MPA for months at low doses with barely any irritation to my nasal cavity. Whatever I have now is getting flushed as I wait for more details on this matter.

I have an update, posted on this thread:

My vendor has verified that there are different batches going around. Some so weak or impure that they seem almost inert.

Thought it was just my dirty old pipe,,seems it isn't just me,,yep the smell is worse
 
Marauder, this is not much but here are my thoughts on different batches :
I had experiences with three different vendors and MPA always came different from different vendors.
First one I have ever tryed was super cleanly white and didn't really had a strong smell, the effects were awesome, I loved it the first time I tryed it, it was like my cities shitty amphetamine only it seemed to have less side effects. Until I once did so much in one night that I cursed and wanted to flush this shit,but well, I never did that because flushing drugs down the shithole is stupid :) So, it was strong, it almost had no odor, only when I insufflated it it had this toilet/chemical/egg smell.
Another MPA was from another vendor and it was almost brownish;y-yellow,it tended to stick together and it even was kind of wet. It smelt like rotten eggs and old kids dick. It even seemed to have some kind of orange specks in it or something,it seemed very dirty. Also,it stinged like bitch, and the drip was disgusting, the last MPA's drip compared to this one was a walk in the park... That's when I discovered the beauty of oral ROA.
ANd the last one , the newest MPA I have and still have stings less than this second one, and the odor is present but also not that strong. It stings and smells worse than the completely white one but better than this second one.
I have to mention that all these batches seem to have nice effects at 50mg's ant they all seemed to be probably almost same potency. Also I have noticed that sometimes this stuff seems wet because when I've taken out of the bag and put it into paper wraps it left some kind of wet residue on the paper, has anyone noticed that ? Why is that?
 
The smell is from the sulfur. I have the 'old kid's dick' smelling MPA that is tannish and it is almost completely inert. It came from the UK where my previous batches came. With the white MPA that had a strong sulfur smell, 30-60 mg railed did the job. This tan compound doesn't stink as bad but I've taken upwards of 2g in 2 hours with zero effects. No sweating, no crash, just a very bad burn and a worse drip.

I didn't mean to turn the thread into hearsay but there are significant differences in people's reports on MPA's effects, side effects and dosages. The source I buy this chemical from showed me pictures of both batches, but claims they are only aesthetically different (which I think is ridiculous.) I identified the one that resembles mine and he is sending me a few g of the other batch to try. I'll report back in a few days.

yes it stinks to high heavens and well this batch is taking it out on my liver today can feel it like shock waves hit it a minute or so after vaping and the a sick feeling comes flowing all over me i know ive been hammering it of late but this seems like a real poor almost toxic batch poisonous shit for some reason and wants chucking
by the vendors
 
Did about 250mg last night orally, my breath stinks today, like rotten egg and cheese.

** and I had a really tight chest on the comedown, breathing problems and insane vasoconstriction. I honestly thought I was gonna have a heart attack.

Hey sorry to interrupt with this, but I'm new to the site and I have no idea how to start a new forum but I also has a few questions pertaining to methiopropamine (or MPA to those who don't know that word). If I takes about 50 mg of MPA, is there any way to enhance the trip for me and make it last longer? Thank you to anyone who is kind enough to answer this! Also, is it better to snort it or take it orally?

IMO, orally
 
Research the net for 'potentiating amphetamines' and see if that helps.

If you take dopaminergics often you should take L-Lysine as a supplement. It's a precursor to dopamine and something for vasoconstriction.

And, the more you do the drug, the shorter it's going to last, unless you control your usage very well (strict rules
like no dosing on X, Y, Z days, no more than N mg/day, etc.

I would assume selegiline (MAOI, careful), piracetam (nootropics, can be bought online), keeping a healthy diet and avoiding multi-day zero sleep binges are probably the two most important things you can do in terms of safety. Rectal might be a better route than Oral. Insufflation lasts the shortest.

I did an acetone wash on a small batch of the tannish MPA. The MPA precipitated to the bottom but whatever is tan remained dissolved in the acetone. I tossed the brown acetone and was left with a small amount of MPA that was lighter in density, with, and did not have a bad insufflation burn. Even just one quick acetone wash (no denatured alcohol or IPA) did wonders to this batch. The acetone was not anhydrous (not dry) and so I assume I lost a lot of product that was dissolved in any water that happened to be in the acetone.

I don't know what the brown stuff is but and did not perform any weight on the dose. I can approximate it to be ~80-90%

I have Oxiracetam and a few other nootropics coming. I will put an update on this mpa batch

I urinate more than normal when on MPA, why is that? Is this normal? Does anyone else also noticed this?
 
I've read through quite a lot of these reviews and I've noticed there's a lot of stupid people posting about MPA, I've only been taking it since April this year but in the recent 3-4 months I've been taking quite some amount with my friends, so I will make a few notes about taking it, smoking it off tinfoil isn't actually toxic, tinfoil is toxic, you need to flash the tinfoil before using it, snorting it completely destroys your nose, hence why it becomes more-ish, you don't get the same effect after the first times taking it because your nostril is ruined, I swapped nostrils recently and started getting the full effects of it again, another great tip for snorting is to heat up a plate in the microwave for 2 minutes, then put the MPA onto said heated plate to cut up and it will turn into a fine powder instead of clumped up shit which hurts like fuck to snort, the longer the hotter the plate, the finer the powder (don't heat the MPA with the plate whatever you do), bombing it tends to not work to full effect unless you bomb quite a decent amount in one go and I have discovered the best way of taking it is actually plugging it, best buzz I've ever had from MPA was plugging it and was over 2 hours before I wanted more, no bad side effects (bit of sweating), no damaging of organs (nose, kidney, liver, whatever), me and a friend have decided that any chemicals we get, other than blotters or pills, we're going to plug it (with separate syringes, obviously, cleaning them after use is also a good idea)
 
It's interesting that people are talking about variance in batches because in 2 years I've never once received anything that wasn't what I consider to be high-purity MPA: a very fine, clumpy white powder with a kinda standard chemical smell and taste. The effects have also remained constant and consistent with what I would expect MPA to do.
 
well ive contacted my supplier about the last batch i had and they are sending me some more out to make up for they say that they have never had any complaints before about any batches of mpa but its not the first time ive had dodgy mpa so we will see if it was just me or the chemical in the morning

anyone else notice that once you have been clean for a few days your appetite goes stupid i mean hunger like you ain't eaten for a month constantly hungry no matter how much you eat ? only noticed after plugging though .

its weird because its one of the only stims that i have no real problems eating on when high
