Junior dos Santos is one of three UFC fighters who has been cleared to fight immediately by USADA after the anti-doping organization discovered that two Brazilian compounding pharmacies sold the athletes tainted supplements.
Dos Santos, Antonio Rogerio Nogueira and Marcos Rogerio de Lima all recently failed USADA drug tests as a result of the tainted supplements. Dos Santos and Nogueira tested positive for hydrochlorothiazide, while de Lima tested positive for hydrochlorothiazide and anastrozole.
“Unlike retail pharmacies and drugstores, which receive their drug inventories from commercial manufacturers, compounding pharmacies prepare their medications onsite according to specifications contained in a written prescription,” the USADA statement read.
