I live in Japan. You'd think I could just find ivermectin at candy stores or whatever, but I really do not know where to begin looking for it---at least not without some prescription. The home center sells antiparasitics for pets, but the selection is very limited. I found something called piperazine. I did a bit of research.

I'm finding a bunch of articles on Yandex, but I am not highly scientifically-minded when it comes to so many various medical terms. If you wanna read something hilarious that came up with my search on piperazine, check this babblespam. It's so funny.

KEK! Reminds me of those bizarre spam email from the early 2000's.
So... erectile dysfunction? I think piperazine enhances nitric oxide, and so does L-Arginine. I take L-Arginine for health and exercise potential. Apparently it plays a part in immunity, anti-fungal, etc.
I know exactly what ivermectin is called in Japan. "Iberumekuchin" is how it is pronounced. I just read people on here saying that they go to Tractor Supply or PetSmart and find it easily. I'm telling you now that Japan isn't like the USA for obvious reasons, and people just don't own horses for the heck of it like people can do in the USA.
I was looking at piperazine to see if its efficacy against COVID-19 has been researched. I did find some data, but not a whole lot. I didn't have to "chase down" piperazine in Japan because that is what is easily found. Perhaps ivermectin can be found at a more specific pet store, but in the small town where I live, piperazine is all I could find. Since it is a parasitic, I did some research about it being used against cancer and thought I'd share what I found with the forum here. You can wish people wouldn't do their own research all you want, but doing our own research is exactly the mindset of this forum, fren.
