RCs Methiopropamine - ongoing tightness in chest?

[AnOwlCalledTim]

Hi all,

so, a friend introduced me to methiopropamine the other week and as it's a methamphetamine analogue and as I have ADD, I took to it like a sloth in a bowl. Bought some on the internet and started experimenting with doses, ROA, etc.

It's been pretty awesome so far, I think my preferred trip is swallowing about 60mg and while waiting the two hour come-up out, taking one or two 20mg bumps. Seems a lot, but I've been testing it hard (it's new, it's fun). But more often I've decided to take a couple of bumps and get the immediate buzz.

Now, the folks on BL and Erowid told me that at higher doses, you can expect stronger side effects without a lot of extra oomph, and I've been wanting to find the limits of that. I think the scariest time was when I took about 150mg in the course of a couple of hours, and my heartbeat went a bit crazy and I got a heavy tightness in my chest. I sat down and chilled out until it wore off and respected dose levels a bit more after that.

But what I've noticed recently is that the tightness in my chest is now an ongoing thing that comes and goes whether I've taken MPA that day or not. I've been checking my heart rate every so often when I've noticed this and it's a good rate: I have a blood pressure monitor and it just came out at 114/72 and 71bpm.

So I'm not on the verge of having a heart attack or anything, and it's not causing me pain or restricting my breathing, but I was hoping that someone might know what bodily process is causing this. Someone else had a similar question a few years ago so it's clearly a thing that happens to some people. Is this just the result of putting this drug into my body several times a week (it's new and each bump lasts about as long as a joint) and I don't need to worry until it bothers me? Or is this a sign that if I keep going, something bad could happen?


Cheers (I have another account, but it's a more "innocent" one, if you know what I mean),

Methiopropamine, like its cousin methamphetamine, has a long half life in the body (12+ hours) and continues acting as a vasoconstrictor hours after the "fun" effects have worn off, narrowing blood vessels and hence increasing blood pressure.

It's certainly not a sign of anything good. I would reduce your dose or take it less frequently.

Yes, I think it's a good idea to stop for a while - the amphetamine family are, after all, addictive and the only way you can prove you aren't addicted is to refrain for some time. I've got a party coming up I was gonna enjoy and then give it a break, but tightness in the chest is not a thing that I have ever had happen before and you're always like, "And what does that mean? Is this bad?" Ongoing vasoconstriction makes sense though.
