So in terms of the science, yes, there is a mechanism for the anti-cancer activity of fenbendazole.

That's why it's great on skin or in the intestinal tract for getting rid of parasites.

Now, yes, it does kill cancer cells at very high doses in culture dishes, which looks good.

But in order to get to the bottom end of those amounts, the absolute minimum, you'd need to take four grams of fenbendazole every single day.

While on the internet, the Tippin's protocol, we'll talk about that later, is about 220 milligrams, or about a quarter of a gram, every other day.

That's more than a 40-time difference between what people say they're taking and what you would need to take to have any effect.

And again, under some circumstances, there is a little bit of evidence, it's bad, but a little bit of evidence to support a slowing of tumor growth.
