Last year in the run-up to UFC 244 and the fight for the BMF belt, Nate Diaz tested positive for trace elements of LGD-4033 (Ligandrol), a SARM. By UFC SOP, any failed PED control calls for any contest scheduled involving that fighter to immediately be suspended.
Diaz flew into a (very public) fit of righteous indignation claiming he ate nothing but whole foods and only took all-natural supplements and swore never to fight again for the UFC until USADA fixed what he claimed was a screwed-up testing procedure and his name was cleared. Then days before the fight, the UFC announced they had cleared Diaz because the concentrations were too low to have any affect on performance. The UFC's announcement also noted that this reflected a policy change they had made in conjunction with USADA just the previous August. To treat positives for concentrations of certain PEDs that are too low to be of any performance benefit as "innocent contamination" and an atypical finding.
So much for "zero tolerance."
The UFC/USADA never commented on the source of the contamination but now a Twitterato (singular of Twitterati) called Dave/Dim has done some detective work and learned that USADA has put a multivitamin made by Plant Man on their "high risk list" because it was found to contain traces of LGD-4033 and another SARM, ostarine, plus the steroid methasterone.
The kicker is Plant Man is owned by Game Up Nutrition, which is owned by the Diaz brothers. Which raises the possibility that Nate tested positive due to a contaminated supplement made by his own company. How convenient.
The more troubling question is what in the hell is a company that makes plant-based nutritional supplements doing with SARMs and 'roids in the factory in the first place?
