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

[clubberdude]

I've jus snorted two lines of methiopropamine and not feeling that good, is chasing the only way to take this stuff? Only i don't chase

I like to take this stuff orally. It comes on within around 30-40 minutes, and gives a nice buzz for a couple of hours, before gradually tapering down. Its a good functional stimulant, great for getting work done, or having a good workout in the gym. I seem to get between 6-10 hours of stimulation with an oral dose of around 60-80mg.

Of course, i'd suggest starting lower than that (I've used this a fair number of times). Snorting doesn't tend to produce favourable effects for me, and I haven't tried smoking it yet, but will do in the next few days.

What is a sensible smoking dose? I have no idea on how much this would potentiate the effects over oral dosing. I'm thinking 10-15mg to start, with a potential top up later if required. Does smoking the chemical really smell badly? It would be better if it was discrete.

I've tried snorting this and eating it. Seem to get more of an effect from snorting....but it makes the nostrils pretty sensitive.

I want to try vapourising / vaporizing, does anyone have any experience here?

It's pretty moreish.

Vaping off foil, Utterly Vile taste, Hideous amount of smoke, if your not experienced at chasing the dragon I suggest using a lemonade bottle with the bottom cut off as a straw so as to catch the vast quantity of light disgusting smoke. Also do it outside till your confident, the smell lingers and as I say.. is horrible.
However, a definite rush is felt with very fast onset, 10-20mg will get me dancing and almost euphoric for half hour (note that the duration of almost every drug is incredibly lessened when inside me rather than when inside a friend) To high a dose and the crash is awful, headache, lethargy, irritable. Not fun. Despite all the cons this is my fave ROA at the appropriate time, studying... Oral... partying, Vaped.

Searched this thread, and didn't find any conclusive information concerning my particular case.
About 5 days ago I went through 300mg of MPA in a timespan of around 8 hours. Effects were nice and suble, a hint of euphoria, calm mind and like with anything else I consume my pupils dilated to the point it's hard to guess my natural colour of eyes. On the comedown I used some zopiclone to attain sleep (had no other fuctional benzo's around at the time.).

Now, even though quite some time has passed my pupils are still a decent margin bigger then they ought to be. In a darkened room it would appear like I am tripping Anyone else who had such an extended period of dilation on this substance? I'm not particularly worried about it, just wondering what others experienced. They do seem to get back to their normal ratio's now though, but this was the first time I experienced anything like this. 300mg over 8h intra-nasally isn't that huge a dose from what I gathered so perhaps I'm just sensitive to it?

To add something about MPA's qualities as a stim; I was pleasantly suprised by it. I was expecting zero euphoria, simply an enhanced state of concentration/focus and lowered threshold for social interaction and that's exactly what it delivered, far better then I expected. And there was no real comedown except trouble with sleeping. Nothing like the jittery aftereffects after a night of amphetamine usage when the euphoria is gone and you're left in a restless state of unease. But that's comparing apples with oranges.

 

[spephspeph]

I get no dilation from this whatsoever.

I don't know if that's the quality or whatever.

The smell of it is nasty, but after a while I begin to associate the smell with the high....beginning of a slippery slope?

MPA is an interesting one, because I seem to get almost nothing from it at all - at the most, it's a slightly methylone-like edgy buzz. I've taken doses up to about 80mg (rectally) and it's always seemed fairly meh to me It's less pushy than methylone, and slightly easier to sleep after taking it, but not much. Does anyone know much about how it affects the brain, which neurotransmitters etc, cos info seems fairly thin on the ground about it at the moment?

No, (afaik) the -kinetics/-dynamics of MPA is relatively unknown! Guess by definition it's still aptly named as an research chem. I'll see if I can find anything however and post here.

 

[spephspeph]

I've seen some papers which suggests that this also has anti-parasitic properties... is this just a 'plant food' / 'bath salt' type claim?

 

[tyrael]

^^^^ I'm (personally) not entirely sure. Based solely on the compound's make-up (1-(thiophen-2-yl)-2-methylaminopropane) I'm sure one more versed would be able to make an educated guess on certain properties. However myself I cannot.

My first experience with MPA last friday. Should note I'm not a raver, investigating MPA as a functional stim as I'm a bit ADD and can't find a source for Adderral/speed. Bought from trusted vendor.

Woke around 14.00, found package containing 1g MPA.

16.30: Need to do some work, feeling unfocused. Take test dose around 4mg +- 2mg (hard to sure with my scale) sublingual. To my surprise, start feeling more clear headed at +15 mins. At +60 mins I'm certain it is helping me focus. Back to something like baseline around +2 hours.

19.15: Around 10mg sublingual. Gentle come-up for first 45 mins. Then same effects with slight mood improvement, definite clear headed focus. Work goes well. Starts to wear off at +90 mins.

21.15: Around 16mg bombed. +30 mins nicely focused now, feeling kinda good though no euphoria. Work proceeds well. Mostly worn off by +2 hours.

23.00: Stop work. Start feeling very minor comedown, generally worn out and thoughts slightly racing/fumbling. Eat a small meal of chilli and rice, not much appetite but hungry.

23.30: Swallow .5mg Etizolam pill. +60 mins feel bit weary and generally ok.

01.00: Need to sleep soon. Swallow 1mg Etizolam pill. Over next couple hours have 3/4 glasses of wine, get a bit stupid and go to bed at 04.00 feeling ok.

11.00: Force myself to get up. Feel ok, mild hangover and sleepiness, nothing unusual.

Over the course of the test, no side effects like chest pain, only bit of an increase in heart rate.

If this was the end of the story I'd be pretty happy with MPA. However for the following 3 days I feel significantly more dull-minded than usual, even more lacking in focus than usual. Make some stupid mistakes. Feel like I've got a cold but without having a cold. General feeling of ill-health and tiredness. Pulse seems a bit higher than usual. Sometimes can't finish peeing, drops just keep coming out, which is very annoying. Get drunk more easily than usual.

---

Conclusion:

Good quick-acting, quick-ending functional stim at low doses with mild comedown which is perfect. However seems to have messed me up a bit since then, though could be a number of other things (maybe I do just have a cold, or haven't had enough sleep lately, or whatever).

Tempted to flush it, but maybe will try a similar experiment (3x10mg doses 2 hours apart) in a few weeks, when feeling generally healthy, for science.

I could not help but notice that on an earlier page, there was posted a picture of the packaging from a supplier. On the packaging was the molecular structure, however, it had the sulphur atom in a different position in the ring compared with the image on the wikipedia page. Are we sure that everyone in here are discussing the same compound?

Recently received a 500mg sample from a trusted vendor. Because I have ADD I was curious if I could benefit from this stim study-wise. I do receive methylphenidate (Ritalin) for concentration and the like, but I rarely take it. The Ritalin makes me feel like an emotionless robot most of the time or just makes me feel depressed. Next to that I get fairly introverted and usually have trouble keeping a conversation going.

This morning I prepped a 25mg capsule and took it on an empty stomach. After half an hour I started to feel a little speedy and started tidying up my room, ironing my shirts etc. This is an indication for me that the stuff works, because I am a pretty messy person and hardly ever clean up unless I absolutely have to. So after half an hour of doing that I decided that it was time to study. I maintained good concentration, even with my housemates playing music (which usually is a killer distraction for me). As opposed to Ritalin, I felt very content. Maybe even a little euphoric. A friend of mine was studying in my house as well and when we went out to smoke a cigarette I noticed I was actually a little more talkative than I usually am. After about an hour of studying my friend left. Unfortunately I wasn't really able to get my concentration back after that. Maybe it's because the MPA wears off very quickly, but I also have to take into account that I haven't eaten anything yet. I still notice some stim effects, so it's probably the latter.

I think MPA might be a good substitute for Ritalin. Only problem that remains is the lack of research done on the stuff. So I will not be taking it too regularly.

Not bad. 20 mg oral yesterday. Felt like a moderate line of speed, but with less euphoria and more increased focus on the task and hand. I felt more effecient at whatever I was doing. Would do again in a situation where increased wakefulness is required without the distraction of euphoria. I feel a bit sluggish today, but there was no crash, only a gentle tapering off of the effects. Sleep came easy 8 hours after dosing.

Slept for like 4 hours tonight, woke up and dropped a 45mg capsule. I feel super awake and ready to study

I slept for 5 hours last night. Dropped 30 mg orally in a gelcap at 7.20 am. Felt very much awake by 8, almost euphoric from 8.30 to 11. Very focused, very chatty, and very self confident. It started to subside around 11. I drank a 16 oz coke at 11.30. I co not a daily user of caffeine. There is a clear synergy and I am mildly euphoric again. It is now almost 1 pm and I still feel great. Fantastic study drug, best I have tried.

 

[Kaaskoek]

Same here. Tomorrow I'm taking 30mg at 7am and wake up at 8am and hit the books immediately

Okay so I have never used any stimulants at all before now, and my drug experiance has only been weed, DXM and recently Methoxetamine and MDAI (no together of course). I decided I would order a gram of MPA as I thought it would be able to help me at work (concentration/work faster/more focused, etc).

Anyway it came today about 10am and even though I have work at 3pm I thought it would be okay to try it. I have tryed smoking it in a homemade lightbulb vape but I'm not sure if I did it right. I put in what I guessed it about 25mg and held the lighter about 2cm underneath the bulb until it melted into a clear liquid, then I kept applying heat until it started to smoke then inhaled. I kept burning it for 2-3 minutes until it wouldn't burn anymore. Is this the best way to vape it?

I have read in this thread people saying a definite rush is felt with very fast onset even with amounts as low as 10-20mg. It's weird though, I don't really feel anything, I want to take more but don't want to risk being too tweaked out for work incase it starts giving really strong effects.

Should I try smoking it on tinfoil or do I just need to keep smoking it in my lightbulb but maybe just use more?

Thanks and sorry if this is in the wrong thread, I'm new here!

 

[Darkridge]

Just an update, I kept smoking it in my lightbulb vape until about 1:30pm and around 2 hours later when I was at work, however subtle the effects I did feel more alert/focused than I normally would.

Finished my shift and having vapes every 30mins or so for the past 4 hours (smallish amount though) and I still don't really feel much. I would expect to feel wide awake but instead I'm thinking about going to bed. Definately noticed that the viens in my arms which are usually massive are much much smaller.

Don't think i'll be ordering this one again.

 

[Kaaskoek]

I haven't vaped the stuff, but did snort and eat it. In my experience, 30-50mg ingested works best for concentration. Snorting hurts like hell and the effects wear off faster, which means re-dosing and more pain.

 

[basement_shaman]

I am not sure if insufflated has a shorter duration than oral. Sure, it might fade sooner, but isn't the full effect also felt proportionally sooner? At least it seems to me that the AUC's for oral and nasal would be very close. I am also curious about this pain you describe that you experience when you insufflate MPA. Is it the usual uncomfortability or is it a unique sensation? I definitely feel a mild to moderate of the former, but as far as I can tell, none of the latter.
