I’m not advocating either approach, but if you want to get a prescription from a Doctor for ivermectin tailored to your weight...
Try this website...
https://covid19criticalcare.com/
They have whole sections on Doctors who will prescribe it and pharmacies that will dispense it...
I got my prescription for ivermectin thru this website.
We found a doctor who would prescribe it and had it filled at CVS a couple weeks ago.
Haven’t taken any yet. Waiting until we pop up positive.

Lots of good reading on that site....even on the vitamins.
