In a doping test after the race on July 11, 2018, the anabolic steroid epitrenbolone was detected in Grove's urine. However, the day before he had been tested negative for prohibited substances. The Usada has not blocked Grove because she believes that the case was a mistake.

Because according to the authority, it is considered likely that the positive test with a meal Groves on the evening before the competition is related: Accordingly, it can be assumed that Grove the prohibited substance when consuming contaminated meat to have taken.

Grove had revealed to the Usada information about which food supplements he had used. Nutritional labeling did not reveal any prohibited substances. Extensive studies of the Usada then showed, however, that epitrenbolone was found in the additive.
