Brazilian heavyweight Vinicius Kappke de Quieroz has allegedly tested positive for the steroid Stanozolol following his UFC 120 undercard loss to Rob Broughton on Oct. 16 in London.
Quieroz made his UFC debut in London and was on a four-fight winning streak before falling to Broughton. The Chute Boxe product is a knockout specialist, having notched all five of his career victories by KO. In his fight with Broughton, however, the “Spartan” was unable to put the Brit away early and became noticeably fatigued as the fight wore on. Broughton pounced on the hulking Brazilian in round three and sent him packing with a rear-naked choke.
Stanozolol is an anabolic steroid derived from testosterone, developed in 1962 by Winthrop Laboratories. Unlike many other steroids, which must be injected, Stanozolol may be taken in tablet form. Commonly sold under the name Winstrol, the steroid is sometimes prescribed to treat anemia and hereditary angioedema. The UFC will reportedly release the findings against Quieroz to the Nevada State Athletic Commission, which may affect the fighter's license eligibility in the United States in the future.
