You can buy ivermectin oral paste for horses on amazon. Buy several tubes- they are very cheap. You can take a small dose weekly for prophylaxis ( 1/4 to 1/2 dose during flu season) or just use it when you get sick. It is important not to wait several days before treating. If you get sick you can measure out 2x your body weight on the plunger and divide it up into 3 or 4 doses to take over the first 24 to 48 hrs of your symptoms. If you are still sick after several days you can take another 2x or 3x your body weight within the first week of symptoms (5x body weight total). That is about 1/2 to 3/4 of a tube max. Doctors are using quite a bit more than this on severe covid patients.  Try to take on empty stomach. Avoid fats especially aroung the time you take it which would increase absorption too much. Avoid taking aspirin, warfarin or other blood thinners for about 24 hours before/after taking this drug.  It has basically no significant drug interactions besides that. You can take it with basically any other covid med without serious interaction.  Message me if you need more details.  Check out this dude’s video on how to dose. https://maximpulse.com/permethrin/ivermectin-horse-paste-for-scabies.html You should be able to figure out how to get the zinc yourself.  I believe at least some of the doctors are prescribing HCQ prophylaxis on speakwithanmd . com , if you wanted to get that drug before you got sick. Most of doctors on that site will give you that drug if you get covid, from what I understand. You might be able to get either doxycylcline or azithromycin from your local GP even if you live in a communist blue state like me, if you test positive.  Both doxycycline and azithromycin have anti-viral properties and you can take either with ivermectin. I probably wouldn’t tell the doctor I was taking ivermectin until after I got the drugs I wanted from them though.
