Depends how you define that. I understand there have been 2 legit peer reviewed studies out of Brazil and Malaysia which have been completed.... So maybe you're correct, it is no longer experimental. It has already been proven to not work against Covid.
But to be fair I think there is still an Oxford PRINCIPLE trial still being conducted which includes ivermectin, so maybe it could be argued that it IS still experimental. Not sure if that is a legit double blind type of deal or how peer reviews will go but ya.
