A class act knows what nandrolone is.
Also, looking through the Shayna Jack hearing docs, it becomes a little more clear why Shelby is going with steak in her and her team's fun shell game. If she said she ordered pork on purpose, CAS probably wouldn't sympathize much, given the publicly available info about offal and nandrolone. So they're going with steak in order for her to have a chance at a reduction via this clause:
“No Fault or Negligence: The Athlete or other Person’s establishing that he or
she did not know or suspect, and could not reasonably have known or suspected
even with the exercise of utmost caution, that he or she had Used or been
administered the Prohibited Substance or Prohibited Method or otherwise
violated an anti-doping rule. Except in the case of a Minor, for any violation of
Article 2.1, the Athlete must also establish how the Prohibited Substance
entered his or her system.” (emphasis added).
