I would love to see a doctor (and not one on the Sky Pay role) explain the treatment of Badzilla.
From what I have read its pretty simple unless I am missing something.
The Dawg's VO2 must have been checked, Sly aint that amateurish. They just dont want to be transparent.
That's why I was asking earlier about which species of Schistosomiasis he has.
The treatment is the same. A single day of Praziquantel in divided doses. 
Side effects are usually mild and nothing like Froome described. Didn't they once say it kills your own cells etc. Total horsesh!t. In only targets adult worms causing a build up of calcuim ions in the cytosol leading to paralysis of the adult worm and eventually death. The only adverse effects are related to the worms dying and may include abdominal pain, diarrhoea etc.
Chemotherapy hasn't been used in ages as it's less effective than praziquantel, even for severe infections, and anybody who uses it needs to go back to med school.
The only adjunctive treatment used is glucocorticcoids for Katayama fever and neurological complications.
— In endemic areas, most studies have suggested praziquantel cures more than 85 percent
of individuals, and reduces the intensity of infection by more than 90 percent, even among those who are not cured . Retreatment of patients with residual infections results in cure in more than 80 percent
. So to not be cured after retreatment is attempted is very rare.
S. Hematobuim has shown treatment resistance.  Which is why I asked what species did he have. The problem with this though is that Hematobuim parasites are located mainly in the bladder wall and symptoms occur very early, with burning urine etc. Any doc would pick it up very quickly. Hematobuim also doesn't cause anemia.
The anemia caused by Schistosomiasis is mainly due to secondary iron deficiency caused by intestinal complications d.t. S. mansoni, S. japonicum, S. intercalatum, S. mekongi.
The fact is that in a first world country this disease is treated easy and you would expect to present early in the disease course. The treatment is simple and fast with minimal side effects. The only time you would expect treatment to fail is when there is a very high disease burden with a prolonged period before treatment, in someone who doesn't have access to treatment.
I think we should find out exactly which species he had and from there it would be easiest to debunk it. I believe he had it. I don't believe it altered his hematology. I don't believe the treatment gave him huge side effects and I also don't believe it's curing is what caused his huge performance gains.
