UFC lightweight returns from six-month USADA suspension from contaminated supplement

April 11, 2019

UFC lightweight Mairbek Taisumov has accepted a six-month suspension from USADA for testing positive for a prohibited substance.  Taisumov indicated that the failed test was likely due to a contaminated dietary supplement.

Stanozolol metabolites were found in an in-competition urine sample he provided at UFC Fight Night in Moscow, Russia this past September.

Via USADA release:

Following notification of his positive test, Taisumov provided USADA with information about dietary supplement products he was using before and at the time of the relevant sample collection. USADA obtained open packages of the dietary supplements and collaborated with the Russian Anti-Doping Agency (RUSADA) to source unopened packages from Russia. Although no prohibited substances were listed on the supplement labels, product analysis conducted on both the open and independently sourced, unopened packages of the products by the WADA-accredited laboratory in Salt Lake City, Utah, indicated that they all contained stanozolol.

The 30-year-old’s period of ineligibility began on October 8, 2018 when he was put on his provisional suspension.

Payout Perspective:

 Taisumov did not miss too much time as he is able to return to the Octagon this month.  The contaminated product was verified by the WADA-accredited lab reflecting that the supplement did not indicate on the label that it had a banned substance, yet it did.  An issue that punishes the fighter despite reading product labels.
