If you are talking about dosing the horse Ivermectin, I went by this video. It’s done by weight. Apparently horses and people metabolize drugs the same way. Dogs and people do not. My first dose was as exact as I could get it but like he said, Ivermectin is very forgiving so I started taking a dose about 20 pounds over with no ill effects.
You might have to watch it more than once for it to make sense.

Thanks, but I am talking about the human form - I hear everything from 12mg * 5 days (if symptomatic) to 39mg, I just don’t know which to go with
For later
