More dishonesty followed by a backhanded insult with mockery for good measure. What class.
I included only the relevant part for brevity. The WADA Lab used a method to establish "exogenous" which they may not use to establish "exogenous" when "invoked by the athlete". The "since varying diets ..." is a explanation for the prohibition, but not the pre-requisite. It would equally apply to the varied diets of soy-fed farm pigs (conceded by Prof. McGlone), as we learned in the CAS report that soy will produce such pseudo-endogenous values in the same range of Houlihan's measured values. It is the varying diet that is relevant, not the "migrating wild boars". That was the focus by all parties throughout the CAS report.
But note again, the WADA Lab reporting is early in the process, before any effort is made to determine the source. Their only guidance of applicability is "consumption of edible parts ... invoked by the athlete". The WADA Lab cannot know whether "migrating wild boars" would be applicable to specific cases during this reporting phase, so cannot reject this guidance on that basis.
You keep saying Iowa slaughterhouse. The pork stomach did come from IBP (Iowa Beef Processor) but (some of?) the meat came from Farmland Foods, based in Kansas City with "processing facilities in Illinois, Nebraska, Iowa, Kansas, South Dakota, Pennsylvania, Georgia and Utah". The PI said he was told "that where the animals are actually slaughtered can be almost anywhere". (Prof. McGlone is wrong again?)
I would consider Ross's expertise regarding exercise physiology, and hydration and heat dissipation during exercise, and even Central Governor theory, but here he brings no scientific value, and is propped up as a false authority. Here he was just a highly paid parrot, echoing the words of the AIU and the CAS. Furthermore, Houlihan's case hinged on legal interpretations of words like "may not" and "may be" and "cannot" and standards of "not intentional", and not the science.
What is more relevant to me is the concession of the dependent scientists, like Prof. McGlone, that pigs were fed soy in the relevant timeframe, and the research of dependent scientist Prof. Ayotte, that says eating pig offal can produce values up to 130 ng/ml, or even 160 ng/ml, in research with small sample sizes, and the express guidance from WADA that says that intact pork consumption will usually produce nandrolone values in urine samples in the low, less than 10 ng/ml range, and exceptionally higher, and WADA research that says varying diets can cause varying isotope values.
