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

[lynx2051]

My MPA arrived today from a well known vendor and it looks quite different to what it used to be. Normally it's very crumbly, off-white colour that used to stink. But this one I have here is pure white and has absolutely no smell to it. Very like cocaine but slightly more sticky.

I am really glad there is no horrible smell anymore. I wonder if it was just poor synthesis that made it stink.

MPa is like the perfect stimulant for me, 35mg orally is really quite nice. Makes me feel quite light and cosey. It seems to have a slight serotonin warmth to it.

Here is what MPA looks like at the moment:

Hi guys, my first post on here so be gentle!

I'd just like to say that I've been using this chemical fairly regularly for a few months now, generally in smallish doses (20-30mg as generally reported on the thread), maybe once or twice a week and I have to say I'm reasonably impressed. I've not been a heavy user of stimulants throughout my life (I'm 25 and didn't really take anything before about the age of 21) but I've tried some fairly good quality amphetamine, generally poor quality coke (hard to get among my usual circle of friends) and smoked weed fairly regularly for a couple of years, though I'm increasingly finding it doesn't really do much for me.

Basically, I guess I'm an ordinary working class fella who occasionally needs a pick-me-up for social gatherings (lots of alcohol makes me pretty drowsy & un-coordinated) and am someone who enjoys the chatty-ness and general feeling of well being you get from feeling awake, alert and in control (whether real or substance-induced!).

I've enjoyed MDMA a few times, but the come-downs are tough, and I find mephedrone really full-on & the comedowns are even worse. So for me, this stuff really hits the spot - it's not quite as 'keep you awake all night-y' as straight speed, there's not the cuddly 'I love you, you're my best friend ever' euphoria you get from MDMA but I find it has a little bit of both, just enough to lighten the mood, make you feel a bit more conversational and feel a bit less anxious about talking about the things in life that really matter to you, especially when you're with close friends.

Obviously the long-term effects of any RC are up for debate, and I'm sure this one is by no means free of toxicity or long term damage, but I feel it does definitely have a use, particularly if you're already fairly functional and just want something that'll cheer you up a bit but won't ruin you for the next day. I'd like to say it's not a party drug, but I think sometimes the effects are just enough to just give you that little edge of confidence you need to approach that person in a bar that you think looks interesting, or maybe to be a little more truthful about how you're feeling with people around you.

It does have it's downsides, though - you don't get much purchase from continued dosing, upwards of 60mg I didn't really get anything else from it so you need to be a little bit careful not to try and chase a buzz that you won't get if you take more (I guess this kind of practice is more likely to be common if you're used to coke, meph or whatever, really fiendy stuff). That said, it does leave you wanting just that little bit more sometimes! It does sting my nostrils a bit I must admit so I'm kind of wondering about alternative routes - does bombing it take longer to take effect like with pills? Would I have to change the dose? Is it effective orally?(gums) I'm not keen on vaping or IV but that's just preference.

I'm a chemist by academic degree so I'd also be interested to see how pure the compounds we're generally getting from the RC vendors are - I'd be disappointed if they were mixing it with say caffeine, though maybe I'm just worried about this because the feeling of alertness I get from it I kind of associate with the same feeling as having a few shots of very strong espresso!

Do we have any concrete GCMS or NMR analyses from a reputable lab on this stuff? I'd be really keen to know that what I was getting wasn't (as one of my lecturer's wrote in a friends lab-book) a horrific mix of products!

So I suppose in short what I'm saying is that it's fairly good for a number of purposes in general life, but if you're after something to put you in another place or get you out of your ****ing tree, then this really isn't the right choice.

It's funny though, I don't really feel any particular boost in my libido as some people have commented - maybe this is a personal thing but then I generally find most stimulants to have rather the opposite effect on me.

Anyway I hope this is of some use to you fellow blue-lighters.

Cheers,
M

Good post^
(Shame about the libido thing though...MPA works for me

Here is how micro-scale recrystallization of methiopropamine looks like.
for starting material i used 750mg of mpa.
As solvents evaporate mpa begin to crash in a weird five corner fractal shape crystals that grows into perfect circular crystals.
pretty beautiful and trippy sight.

i`ll post few more pics of final result when it will be done.
key to good recrystallization is to do it nice and slow... room temperature over few days is a good thing.

Gc/ms & nmr

@BlackDog_69: Great post, very informational,
I`ve been using myself mpa for few months, on and off. I dont have super crazy sex drive from it either, nothing like artificial methamphetamine libido, if one would compare mpa to methamph.
If you are interested in GC/MS results, here is link to analytical profile of methiopropamine.
source: U.S. Department of Justice
Drug Enforcement Administration
Special Testing and Research Laboratory
Microgram Journal, Volume 8, Number 2

http://www.justice.gov/dea/programs/forensicsci/microgram/journal2011/mj8-2_53-57.pdf

There is quite a lot of information about MPA on justice.gov/dea/
i found much more info about compound and what it metabolizes into in human body on their website than wiki or anywhere else.
Also, some rc vendors can provide you with gc/ms and nmr for compound you are ordering..for someone who dosent know analytical chemistry its bunch of numbers,
but if you understand meaning of chemical shift measured in ppm. you can take your vendors compound test result(if you have one) and compare it to results dea chemists provided in microgram journal.

i hope that helps.

Have noticed that recent batches are smellier and more painful up the nose than previous batches

Good mpa should burn like hell for 5 or 10 minutes..a slightly salty/plastic smell is normal for mpa because of Sulfur in thienyl group but if its too stinky it might be not pure(contaminated)

A friend with no computer asked me to research MPA and here is my first observation about this thread: Early reports (first 10 to 15 pages) are much more negative, then the reports gradually get better and better.

Why would user experience of MPA get better over time? My guess is that RC suppliers are always looking for better synthesis and purity, and they learn from their mistakes. Early users get the worst of the shit. As long as a substance and its precursors are legal in most places, there should be a gradual improvement in quality and cost of synthesis, although unscrupulous manufacture and sale of any chem is always going to be a problem. This is even an issue for vitamins, herbs, and supplements sold in retail stores.

My friend's experience yesterday went like this:

5 mg sublingual upon awakening, test for allergy. Tiny effect of alertness better than coffee (more smooth and steady.)

10 mg sublingual about an hour later, during breakfast with coffee. Effects noticed more within 15 minutes; some nice feelings in body, more sensitivity; he said he was looking for the libido effect because of what I found in this forum and he did feel that.

15 mg sublingual another hour later and after breakfast ~PLUS~
40 mg MDMA sublingual at the same time

One hour later (3 hours past beginning of experiments) --- pleasant and mild feelings, good combined with the MDMA for more physical sensation and slight euphoria, very positive attitude and continued libido effects.

He checked his blood pressure and it was pretty high considering he had taken his usual BP medication with breakfast (143/93, pulse = 91) so he took another dose of the BP med. He says this could be due to the MDMA so he doesn't know how MPA alone would affect him.

Warning: "too much information" follows --- he wanks and finds that the MPA helps offset the sexually frustrating side of the MDMA. His guess is that keeping the MDMA to barely-noticeable levels (mainly used to enhance physical pleasure and euphoria) is important for being able to maintain erection and achieve orgasm.

Comedown: gradual and mellow.

The MPA was procured from a well-known eastern EU vendor with which he has had very good experiences in the past. The substance is a fluffy powder, like corn starch or powdered sugar. Taste is minimal and easy on the tongue, but he is able to put PIRACETAM directly on his tongue and doesn't mind it!!!, so... he's crazy.

Legal questions: "Although it is claimed to be legal, it is a 2-thienyl analog of the Schedule II controlled substance, methamphetamine, and may be controlled within the United States" --- this is from the DEA's own web-published analysis of MPA!!! If the DEA doesn't know whether or not a chemical is illegal, then maybe this isn't a wise thing for Americans to import...? My guess is that they would only go after large importers, not low-level users, but everyone must make his/her own decision.

Some closing thoughts:
- MPA might frustrate serious drug users and is probably better for those who think coffee is a strong drug (which it is!!!)
- Quality and purity are up for grabs, very inconsistent based on user reports
- some people appear to have serious allergic reactions, thus this is a chem that MUST be tested at tiny doses
- all drugs, supplements and herbs have potential to be harmful or even fatal to those who have bad reactions/allergies. Example: Lamictal (lamotrigine), which comes with a very small risk of a user developing a potentially fatal reaction which is initially indicated by a rash. MPA experimenters are reporting strange physical symptoms, especially on genitalia --- good grief, if this happens to you then STOP USING IT, there is no drug worth losing your life or even your balls!

May we all be healthy and happy. Namaste, and good luck.

I'm not so sure about this - I think it may be a natural progression of big & dandy threads. Those who are up for trying everything come at the beginning and the split of good:bad depends on genetics of users and how good the chem is. As time goes on, you get less people who are trying it for the sake of doing so, and more who are trying it because they like stimulants.

As well as this, all the people who didn't like it unsubscribe and disappear, so you're left with those trying it because they like stims and those who like it for whatever other reason.

If you look at the B&D thread for MXE, you'll see the same thing - the most recent iterations are one big " I love MXE" circlejerk.

Sidde-effects

My friend has couple times experienced with MPA, but has some really bad side-effects.
MPA is from reliable vendor with good reputation, he ordered MXE and AMT from them with excelent results. It´s white fluffy powder that sticks together and weight much less than it looks like. Also, snorting seems almost impossible because of pain he get from it and he blows a looong time after dosing.

Now, the side effects I mentioned...

On MPA, especialy on doses above 50 mg, friend get EXTREMELY high blood pressure. I don´t know exact numbers, but when he touch his neck vein, It´s pounding so much that he get scared. He get moderate to servere headache because of it, which starts about 2 hours after dose and ends sometimes hours after other effects wear off.

MPA too caused him several times moderate depression, which is really wierd because it has never happend to him so often with any other chemical he has ever tried. And that happend with low doses around 10-20mg, too. One time, when he mixed about 50mg MXE and 70mg MPA, It ended with a very bad trip and he even puked because how crap he felt mentally. That was only time he puked on MXE, and he could say He´s pretty experienced with this chemical, got a few 150mg+ trips and never ever happend that he would have a bad trip or even nausea from It, so he can imagine that that happend because of MPA.

Still, MPA helped him a lot to end daily weed habit (but nothing is over yet, he´s just few days off).

Anyway, because of strengh of side-effects, he flushed the rest of MPA to the toilet (twice! - I just want to give it another chance). It´s just obviously not for him.

Sounds like a hell-of-a-bad-trip..
My guess, is your friend is sensitive to stimulants, or had no experience with stimulants. Considering he took such low doses
On another hand , ending his weed habit by taking MPA is a stupid thing to do.
Because MJ lowers your blood pressure, so if he was daily user of pot his blood pressure was always lower than normal 120/80,
When you quit pot after smoking for few month, 1st week of quitting your blood pressure and pulse rate will be much higher than normal,
you sweat, anxiety, paranoia , headache and panic attacks... etc.
MPA is known to rise blood pressure and pulse rate as much as methamphetamine does,
so by quitting MJ and taking MPA instead he probably double or tripled his BP and Pulse rate,
Got scared and had panic attack, if he would smoke a joint after he felt his neck vein and felt pulse rate is too high, he would`ve felt much better,
Weed is actually best BP lowering medicine, especially when you come down from speed trip and your blood pressure higher than a hippies after 3rd day of burning man,.
I did as much as 3000mg+ of methiopropamine crystals over course of 24 hour binge. did 200 mg IV wacks after vaporizing over 500mg over few hours.
My blood pressure was 150/90+, pulse rate by the end of binge was 120.(way too high)
it dropped to 135/80. pulse-85 after i smoked half gram of some good purple kush.
I slept for 6 hours woke up fresh and marched to work as always. Never had signs of depression, feeling of boredom big time,yes, but never depressed
i have digital blood pressure monitor from A&D Medical.thats made for hospital use in Canada, so i trust its readings.

 

[k72x0]

Good point, It might be possible that quiting MJ probably worsed It.

On the other side, he's not totally newbie in term of stimulants. He was smoking MDPV (miss it soo much) back in time for almost 6 months, few times go trough 1g over 24hours and never had problem like this, just usual paranoia..

Couldn't it be some kind of allergic reaction? He dont have any itch, but his face and some other parts of body turned red. But more likely he things it was caused by high blood pressure..

MDPV is more like cocaine freebase or crack by its actions in human body
MPA is analogue of methamphetamine. does he have previous experience with amphetamines or meth?
If his face was red but cold and cheeks swollen, than yes its minor allergic reaction.
Also if feet and hands were cold and swollen its also sign of medium allergic reaction
and i would say if his testicles(one or both) got red and swollen, it could be a sign of medium allergic reaction.
Serious one is anaphylactic shock, but its not likely to happen with drugs that increases your epinephrine(adrenaline) release in the body, and MPA is one of those drugs,

Can someone tell me more about this?!

MPA causes me a real problem with peeing, worse than any other stimulant and worse than mdma. As I usually have a few beers over the course of a session it can get eye-wateringly grim by the end of the evening.

I guess it depends on how much are using. If you use it only as functional stimulant (around 40mg orally, 2 x per day, 3-4 hours apart) it seems pretty easy on the body, not even heart beat is noticably higher and not problems with peeing (from my experience).

 

[Ne0]

It seems it keeps you up very long after taking even little as 50mg. I didn't redose, so after 9h I could get some sleep. I don't have any sleeping remedies, but I can get anti-histamine (meclizine), so just asking will drowsiness inducing anti-histamine generally help to get sleep after stimulants?

 

[Cyanoide]

I only use stims for functional use and MPA has been the best stim for this purpose for me. Better than speed (d-amp) because it's too euphoric and distracts me from what I should focus on. MPA feels quite much like speed but with less euphoria and jitteriness. Slightly euphoric and gives me a quite big ego-boost. I've used it successfully at work when I felt lethargic and have taken it at family/relative meetings which are god awful boring. It's just a bit moreish, even in functional doses, but just about every stim is moreish for me when I snort it.

Anyway of all the RC stims and for functionality MPA has been the best one for me. I try to stay away from it though, because I easily start taking it too often. It really keeps you up for quite many hours too, a bit too many. Never had any comedown with functional doses either.
