Hey buddy, There are lots of anecdotal stories on the net about Ivermectin but so far they’re just stories.
I totally get where you’re coming from - try anything at this point, right? But this is probably not the answer. I don’t know what treatments you’ve had but some guys on this forum have had “triplet therapy” using chemo in combination with specific hormone drugs or Pluvicto.
Just to respectfully ask, were you treated at a center of excellence - like a Mayo, Sloan, Andersen type center- or by your local doc/urologist? Going to one of these hospitals can make a much greater impact on your longevity than some unproven dewormer. Best
Phil
