I personally know a person who had covid and went the ivermectin route at home and was clear in less than 3 days. He did not ingest. He diluted and rubbed on his inside forearm like lotion. I've had vet dilute ivermectin for years to give to dogs for worming and such. When you have multiple pets, vet treatment gets expensive. Breeder I got my dogs from did same thing. You buy a bottle at tractor supply, take it to vet and let him know its for the dogs. He dilutes that small bottle into about a half to 3/4 pint. I give about 1 mil per 40 pounds monthly orally. I'd bet you even have to have the proper dilution for horses, and administered by weight. You don't do ivermectin straight out of the bottle for anything. It's a concentrate. People that have reacted adversely to ivermectin apparently were not smart enough to have diluted first, then administer per body weight. Now, I seriously doubt I would ever go that route, but if you are daring and you exercise some form of knowledge of the product and it's dilutions, you more than likely would be safe from adverse reactions.
