Thanks for the concerns. I've taken 2-FMA, 2-FA, 4-FA, 4-FMA, and other stimulants many times. They are decent and have their place but methiopropamine is completely different in its effects on my brain and body.
From dozens of past experiences, I know the tremors are due to being low on dopamine and that tremors are a warning sign to quit or pull back, not a side effect to hide and continue down the same road. However, the latter is the reason I started the thread, and to give an update, Benztropine works well to stop tremors. This drug is given with anti-psychotics which act on dopamine (in a different way) but also cause tremors.
Of the stimulants I've done, I have to admit that methiopropamine feels like the cleanest and does not raise my blood pressure or heart rate very much. I take it with vasodilators and massive amounts of vitamin C, always. This isn't an elixer but if we're going with the harm reduction approach, I suggest everybody get Vinpocetine and L-Arginine (an immediate precursor to Nitric Oxide; also a vasodilator.)
Vinpocetine is reported to have cerebral blood-flow enhancing[2] and neuroprotective effects,[3] and is used as a drug in Eastern Europe for the treatment of cerebrovascular disorders and age-related memory impairment.[4]
Vinpocetine is not approved in the United States for pharmaceutical use, but it can be sold as a dietary supplement. Vinpocetine is widely marketed as a supplement for vasodilation and as a nootropic for the improvement of memory and cerebral metabolism. Vinpocetine has been identified as a potent anti-inflammatory agent that might have a potential role in the treatment of Parkinson's disease and Alzheimer's disease.[5][6]
Stimulant binges, especially avoiding sleep, nearly always lead to slowed movement (you literally move your body in slow motion), tremors and other Parkinsons'-like symptoms. I never had a doubt that stimulants increased the chance of getting Parkinson's disease but I'm surprised at how big of a risk they pose according to the quote from the study posted above.
READ: I highly suggest against the advice of taking beta blockers with stimulants.
It's known to be lethal to mix beta blockers with stimulants. It might not be lethal in some cases, but unless you're advised by a doctor (MD, not a shaman or intelligent friend), it's safe to assume the combo is lethal or very damaging to the heart.
Back to MPA: My vendor has verified that there are different batches going around. Some so weak or impure that they seem almost inert. 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. 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.
This has nothing to do with tremors and so any updates on this will be posted on this thread:

Selegiline is interesting and I've had good experiences with it as an antidepressant. I'm interested in Emsam (Selegiline in the form of a patch instead of tablet.) I don't currently feel safe experimenting with MAOIs, whether selective for MAO-B or not, being on meds and already experimenting with chemicals that might have MAOI properties of their own.
For the record, I don't plan on staying on stimulants for the rest of my life. It's just a phase. To add to the warnings above, stimulants are catastrophic to short and long term memory. This alone is reason for me to keep away from them. This was not meant to be a "how to safely and discreetly stay on amphetamines for the rest of your life" thread. It was to provide us all with insight on handling tremors from dopaminergics.
MPA is very interesting and to me and has a completely different profile than other amphetamines, at least in my experience (I'm on wellbutrin which keeps my dopamine at a relatively stable level.) Subjectively, it feels more like Modafinil or caffeine without jitters.
