In an extensive video post on Instagram, Brazilian Games athlete Larissa Cunha announced she received an e-mail from CrossFit stating that she failed a drug test, testing positive for Ostarine, a SARM compound and banned substance.

One big thing: Cunha qualified through her first-place finish in the Brazil CrossFit Championship, which was conducted online and not in person. Since she qualified through an online competition, she was not tested immediately. Athletes who qualify through in-person competitions are tested on-site after the competition concludes. 

  • Cunha said, she was contacted by CrossFit to schedule a drug test about a week after punching her ticket to the Games.
  • She was then tested while she was quarantining in Mexico before heading to Madison on July 14.
  • CrossFit e-mailed Cunha stating that she failed the drug test last Thursday, July 22.

Cunha claims her supplements must have been contaminated, leading her to file an appeal.

  • “We know that there may have been an error in the laboratory, so we appealed for a second test, as we had the right and I am waiting now to find out if it will be negative or positive…I have a clear conscious, that I didn’t do anything nor take anything.”

The morning of Tuesday, July 27, Cunha received another e-mail from CrossFit stating that her B sample also came back positive and her Games ticket was revoked.
