RCs MPA & Ethylphenidate contraindications?

[Blue Druid]

Does anyone have any knowledge of the safety or otherwise of taking Methiopropamine (MPA) at around the same time as Ethylphenidate?
I've tried searching but haven't come up with much other than comparisons.
Any idea of potential effects of this combination or any reasons not to try it?

Thanks

They both work in very similar ways but I don't see anything inherently dangerous with taking a bit of both to add up to a regular dose. Just be sure you account for possible synergy.
