The smoking gun evidence in this case is really the isotope analysis of the nandrolone in her sample. It is much more probable that the nandrolone in her system came from supplements than from offal. She never had a plausible case for offal ingestion, and it was casually racist to think that people would be more accepting of her story if she blamed the unintentional ingestion on Mexicans -i.e., it's supposed to be more plausible somehow that the taco truck was serving mystery meat.
Your smoking gun evidence is ambiguous.
The test for the carbon isotope ratio is confounded by intact pork ingestion. The guidance from WADA explains that "Following consumption of the edible parts of non-castrated male pigs" "The origin of the urinary 19-NA may not be established by GC/C/IRMS analysis, ..."
It is not possible for the carbon istope test to distinguish the endogenous nandrolone from intact boar ingestion, and the pseudo-endogenous signature of "19-norsteroids preparation".
It is not racist for her to say she bought a burrito from a food truck serving authentic mexican food (as opposed to American chains).
