De Souza, 20, tested positive for 19-norandrosterone (19-NA) and 19-noretiocholanolone, both metabolites of nandrolone (19-nortestosterone) and other prohibited 19-norsteroids, as the result of a sample collected out-of-competition on March 8, 2023. Nandrolone and other 19-norsteroids are non-Specified Substances in the class of Anabolic Agents and prohibited at all times under the UFC Anti-Doping Policy and UFC Prohibited List.

Upon being added to the UFC Anti-Doping Program, athletes are required to declare prohibited substances they have used in the previous 12 months. An athlete who makes such declaration will not be deemed to have committed a violation but, depending on the substance, may be required to refrain from competition for a period of at least six months and provide at least two negative samples. De Souza did not declare the use of nandrolone and/or other 19-norsteroids on his onboarding declaration forms.

De Souza’s two-year period of ineligibility began on March 8, 2023, the date his positive sample was collected.
