www.Virex.health Of course you understand, anon, the products sold here are only for pets (nudge-nudge, wink-wink). I have no affiliation with them besides being a satisfied repeat customer. You receive the real stuff in sealed and properly labeled packages. I've taken one IVM tablet every month going on 5 years now. I did get a medium bad case of COVID back then. I had horse paste to get me through it. Since then I haven't had anything, not even the slightest sniffle. I can't prove a negative, but I'm a believer.
