Thiago Silva’s UFC 125 Drug Test Comes Back NOT Human

Thiago Silva didn’t test positive for a banned substance at UFC 125 when he defeated Brandon Vera by unanimous decision. While it was clean, it apparently also wasn’t HUMAN.

Her is part of the complaint,

  • The Urinalysis reflects a Complete-Invalid Result indicating that the specimen submitted by SILVA is inconsistent with human urine. The results of the Urinalysis are reflected in the Toxicology Report, attached hereto as Exhibit 1.
  • The specimen submitted by SIVLA was also tested by the Sports Medicine Research & Testing Laboratory, which is accredited by the World Anti-Doping Agency.
  • The Test Report from the Sports Medicine Research & Testing Laboratory reflects that the specimen submitted by SILVA is inconsistent with human urine. The Test Report is attached hereto as Exhibit 2.
  • SILVA submitted an adulterated and/or substituted specimen for testing for the Urinalysis.

The Nevada State Athletic Commission has suspended him until April 7th, where he will have to explain himself to the commission and a formal judgement will be made.


  1. HA HA HA f'in HA HA. Guess in brasil they never heard that they can tell if something is from humans or animals .

  2. Alexandre says:

    Excuse me bro but there is nothing to do with Brasil man . he trains at American Top Team in Coconut Creek, Fl. Let him explain himself then we comment about it.

  3. yeah but he was educated in brasil! do you think someone at att said inject some dog piss into your bladder so you piss clean. you would think one of the other guys there who do not dope would have given him some of their piss! also there is one simple answer thiago stay off the juice!!! sucre esta muy mal ! bom dia ( good day)

  4. He's not the first in MMA to be caught injecting himself with non human piss. But really at the level of the UFC you've got to think that they will find out. I don't get why he would do that.

Speak Your Mind
