You are thinking about FenBen aka Fenbendazole. What Joe Tippen took for lung cancer. Also sold as dog dewormer called Panacur at Amazon etc —— But I agree that HCQ and Ivermectin most likely work against cancer because they stimulate liver detoxification. But me sneaking suspicion is that Fenben is the best of the three. Take the powder with some olive oil or DMSO

I’m aware of fenbendazole and Joe Tippen, and that’s fine since that particular anthelmintic is readily available as dog dewormer, but every drug in that class appears to be potent against cancer as well. Albendazole seems to be the best.
