Ivan Shtyrkov signs with Rizin after ‘abnormal’ drug test result kept him away from the UFC
“When Ivan Shtyrkov signed with the UFC, he was immediately subjected to USADA testing,” Rubenstein’s statement read. “During one of those USADA tests, Ivan’s sample came back with an abnormal reading, not a positive test for PEDs. UFC decided it was best to pull Ivan from the fight in Saint Petersburg until more tests could be concluded. After two more laboratories did tests on the samples, they found that even though the levels of testosterone in his body were within the legal limits, they couldn’t determine that the testosterone was only naturally produced. Ivan maintains that he has not taken anything on the USADA banned list for the previous 10 months, however the UFC and USADA’s look back window is one year, and as we have seen with other athletes in the UFC, some substances can stay in your body significantly longer than that one year.
