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.

https://applbiolchem.springeropen.com/articles/10.1186/s13765-021-00651-0#Sec12 "can act as an anticancer chemotherapeutic by stimulating the intrinsic mitochondrial signaling pathway to induce cytotoxicity and apoptosis in cancer cells."

https://peerj.com/articles/1588/ "displayed a strong suppressive effect on liver cancer cells"

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.
