Oh forgot this little gem -- sure that is one possibility, but there was no evidence in the case supporting that possibility. No receipts. Just a possibility that this could be a possible alternative. One could say it is possible but unlikely. Even if statistical population evidence were presented, it's still not possible to say whether, in Shelby's specific case, that a nandrolone precursor is more likely than accidental ingestion from a burrito.
Let's not forget there are decades of research conducted by Profs. like Prof. Ayotte, proving intact boar can cause positive tests exceeding WADA's low threshold, with values as high as 130-160 ng/ml from one meal, as well as confirming the impact of foods like soy and corn on the carbon isotope values. Prof. McGlone gave us the order of 1 in 10,000 intact boars able to cause positive tests when eating their nandrolone rich organs. In the USA, this is 12,000 time bombs per year, across the nation, meaning it will be rare, but is just a matter of time before athletes get caught from eating intact boar offal. Surely this figure is an under-estimate during the pandemic, for many reasons presented to the CAS, than the general population conditions during normal non-pandemic times.
Don't we all just want the truth? All I want is for the Profs. to tell whole truths, rather than picking just the half that supports the party of one side in a dispute.
