Ivermectin is a molecule. The same molecule is presumably used in horse paste as is used in human pills. Our bodies will not know the source of the molecule.
Our government assumes that the people are stupid; certainly the FDA does in spouting this nonsense.
its not uncommon for both the animal and human versions of medicines to come off the same production line at the same facility.
If I were to contract the covid, the first thing I would do is take ivermectin, not call the FDA for their political advice.
I don't believe a word these government agencies and bureaucracies tell us anymore. Their lies and duplicity have made me a cynic. They all have been politically weaponized and have agendas other than the public's wellbeing at stake.
