I have to agree with you, I think the Humaworm treatment is good only for people with light infections and perhaps only in their intestines.
In case someone has got a systemic heavy infection, even doubling the dose doesn't do much, works just to annoy the worms from my experience.
It makes them a little bit weaker but definitely the regular Humaworm formula even increased to a double dose doesn't produce a systemic worms removal.
