I got some Eraquell wormer pellets 'for my horse' and noted they contain 140mg of ivermectin[only] so could be used as 10 x 14mg doses at $2.60 each. Best taken with some milk!
When I see my doctor soon i'm going to ask for a prescription for ivermectin based on the premise that I wont be having the vaccine. I expect to get it but if not there are alternatives.
Wholesale ivermectin is about $150 per kg. That's 15c for 1,000mg.
