Quercetin: they have some in Costco Spain, but I do not know if the dose is appropriate. I need 500 mg. I have to go to the store and check.

I do not think you can order medicines from abroad. And I am a bit afraid of doing so. Even from the US, let alone 3rd world countries. But it seems it is my only option at the moment.

I have read that IVM prophylactic can be substituted by Nigella Sativa (FLCCC) but I do not want to take something day after day after day.
