Both excess serotonin and dopamine will induce a hypertensive crisis/serotonin syndrome if enough is present so doesn't matter what you use... think of PMA, a potent serotonin releaser and MAO-A I in one and MAO-B I say selegiline with methamp.
While technically yes a MAOI can prevent neurotoxicity obviously by preventing dopamine oxidising, it is too risky to get the right dose - the results will be very unpredictable and there is a strong chance you will wind up in the ER or a body bag. Neurotoxicity will be your last concern when your dead anyway. Although the trip report I posted of a MAOI+MDMA the bloke winded up with severe depression/axniety... so there is some neurotoxicity still with reduced oxidative stress potential.
I am telling you not too do this, it's out of the question. I can see you are still interested in trying this as you said thanks for the replies on stopping you from rolling on a MAOI and then obviously went and looked for it more, so the only serious question here is are you that stupid?
