Pro-Zap is the generic version which has no lidocaine in the formula so it burns like a hot match for a half hour after injection. The more expensive brand name has lidocaine in it and after two seconds you don't feel it at all besides the needle sting.
I used to watch the lambs and sheep jumping around like crazy after the Pro-Zap shot so I always made it the last one to give them.
Our doctor put my family on Ivermectin when my son tested positive. And my wife had been on HCQ for years. We were already taking high doses of zinc & Vitamin D.
2 of us, including my wife, ended up hospitalized with COVID pneumonia. 2 of us had asymptomatic COVID.
