USADA followed their own protocol.
"If a Prohibited Substance is administered via IV infusion or injection a TUE
application must be submitted for the Prohibited Substance regardless of
whether the infusion is less than 50 mL or the setting/circumstances under
which it is administered. In situations of medical emergency or clinical time
constraints, a retroactive TUE application is acceptable (ISTUE 2015 article 4.3)."
