But I do remember being on a medical forum then where people were talking about sourcing it at feed shops because it is a fraction of the price. I didn't have insurance then (don't now, either--didnt see a doctor when I had covid) and was like hm but I did get the human stuff from a pharmacy.
The discoverers (inventors?) of ivermectin won the nobel prize for it btw.
No real point here except that ivermectin is a real and afaik safe drug for humans that helped me a lot. I've seen the horse paste stuff and it does seem a bit of fighting ignorance with ignorance
