On Friday, Combat Sports Anti-Doping (CSAD) announced that Bruno Silva has been suspended for six months for violating the UFC anti-doping policy. Silva tested positive for 3a-Hydroxy-2a-methyl-5a-androstan-17-one, a metabolite of anabolic steroid drostanolone, through a urine sample collected on April 11.
The UFC middleweight submitted urine samples on March 30th, April 30th, and June 14th to Drug-Free Sport International (DFSI). All three samples were negative.
CSAD stated, “In addition to the above test results, which CSAD and its anti-doping experts have concluded are indicative of low-level contaminant exposure, Arruda da Silva also provided significant cooperation throughout the results management process, including multiple interviews and the provision of supplements and medications he was using for laboratory testing analysis. While the source of the metabolite was never located, CSAD’s science advisor concluded that his sample results alone indicate that the drostanolone was NOT injected, that the exposure was very likely unintentional and based on the negative “bookend” results surrounding the low-level adverse finding, offered no significant performance enhancing benefit gained from this exposure.”
Bruno Silva’s suspension has been effective since April 11th. Silva will be able to step into the octagon from October 11th onward.
