CHEWBACCA: On October 24, 2019, Nate Diaz released a public statement regarding a recent out-of-competition test conducted by USADA. UFC has been notified by USADA that the out-of-competition test concluded that LGD-4033 was present in Mr. Diaz’s sample at an amount below the decision concentration level for this substance. USADA is reviewing the out-of-competition test as an atypical finding. Further laboratory testing conducted by the Sports Medicine Research and Testing Laboratory (SMRTL), a WADA-accredited lab in Salt Lake City, Utah, has confirmed that two bottles of the same organic, vegan, plant-based daily multivitamin that Mr. Diaz was using were each contaminated with LGD-4033, which the evidence supports resulted in Mr. Diaz’s positive sample.
Mr. Diaz has not committed an anti-doping policy violation, has not been provisionally suspended and is not subject to any sanctions. Additionally, UFC has been informed by independent experts who have determined that there is unequivocally no appreciable performance enhancing or therapeutic benefit from the significantly limited amount of LGD-4033 that may be present in his system, which is roughly 10,000 times lower than one LGD-4033 therapeutic dose.
