As far as anyone knows, Houlihan was drug-tested as an innocent person, and she was considered an innocent person until the tests convinced the authorities beyond a reasonable doubt that Houlihan was guilty of every element of the alleged offense. After all the evidence and arguments, CAS had neither a scientific nor a reasonable doubt as to Houlihan's having committed any one or more of the elements of the doping offense, and upheld that she is, indeed, guilty.
Houlihan's case is based on frivolous or fanciful doubt as to how tested positive for the nandro, namely they tried to easily explain it away by the uncastrated boar theory, pork stomach to be precise.
If the uncastrated boar theory were remotely true, what happened to the approximately 1/4 of the burrito that remained, having not been eaten? I presume Houlihan simply wrapped the remainder of her burrito in the tin foil and pitched it in the rubbish bin at Courtney's house. Why the hell did neither Houlihan nor Courtney Frerichs nor Lindsey Frerichs not stop eating their fricking burritos and bag the suspect burrito(s) the moment one of more of those burritos appeared 'off'?
Who takes chances like that in an Olympic year?
People ask who in their right mind would take nandrolone in these days, especially a distance runner? Nandrolone does have its benefits, including potential to improve an athlete's ability to train harder; reduce tiredness, meaning athletes can recover quicker from a hard training session.
This is an Olympic year; the last two years have been Olympic years.
CAS has proved all of the elements of the Adverse Analytical Finding beyond a scientific doubt, and rightfully conferred that Houlihan is, indeed, guilty.
