Piracetam doesn't conflict with anything. However, if there is concern about health, then it must be borne in mind that MDMA strongly narrows blood vessels, and after all, there is a problem with them, since piracetam is prescribed. It will definitely not bring any benefits.
By the way, piracetam is a substance with unproven effectiveness. I advise you to contact a more competent neurologist to prescribe working medications.
Usually, the desire to take psychoactive substances indicates a low background of mood, this also needs to be dealt with. Antidepressants and / or healthy habits may help.
In general, Mdma should not be used. as not as a prohibited substance. And with perocetam, you shouldn't have anything to use if you have prescribed it to restore blood circulation in the brain. At this moment, it's time to think "maybe it's enough to hawala with everything that inserts?"
