I had covid back in March. Used off the shelf ivermectin from TSC. I weigh 260lbs, and I used a half dime sized amount. Symptoms were severe, but cleared up in about 4hrs of treatment. Only side effect was a temporary partial loss of vision in my right eye as a worm that I didn’t even know I had, died and floated to the surface.
Did you use the pour on ivermectin for cattle?
