That's because they aren't controversial - most hobby joggers are taking them. If you read the report, you get a glimpse of the stuff he has been doing which is absolutely massive/insane. All elites/coaches downplay the stuff they are using, first so they don't look like their performance is significantly boosted by supps, PEDs, infusions, thyroid meds, etc. and second so other competitive athletes don't find out about stuff that would improve their own performance.

"Hi Dathan, I think beta alanine, aminos, fish oils, iron, calcium for you,
possibly magnesium- am checking with UK docs on this, calcitonen, vit d
, and then this new stuff [i.e., Nutramet]. I don't think I'm going to
reorder any more of the other herbal stuff. There is just no hard
evidence it does anything for testosterone levels or recovery, -
Alberto"
(Nutramet is L-carnitine in case people don't know). He was obsessed by finding anything that would boost testosterone levels that is not on the anti-doping list. He was circumventing the official anti-doping measures by inventing and finding new ways to improve performance that no one else knew off. For example, L-carnitine infusions greatly increase TSH-values (as evidenced by Rupp), which require to be treated with higher dosages of lexythyroxine and cytomel (which he immediately prescribed to Rupp). But he kept all of this a secret - instead of sharing it with the world, he e-mailed this to Rupp:
"Hi Galen , take a full extra levoxyl tonight and start on cytomel right
away. We're not going to wait for another TSH test. You've been sick
before and never had a TSH go to 3.0. It's got to be the Lcarnitine. This
is great news! no one else will know this possible side effect of the
drink. -Alberto. Ps – vie [I’ve] got cytomel. If you don't have it, call me and
I'll drive it over."
