Thibault Gouti has been suspended six months by USADA for testing positive for multiple banned substances, the UFC’s anti-doping partner announced Tuesday.
The UFC veteran failed an out-of-competition drug test administered by USADA on March 12 for ostarine, LGD-4033 and its metabolite di-hydroxy-LGD-4033, and GW1516 metabolites GW1516 sulfoxide and GW1516 sulfone, according to a USADA statement.
Gouti used a dietary supplement for two days before realizing ostarine was listed on the label, per the statement. He then returned it to the store he got it from. USADA tested both the open and independently sourced, unopened containers of the product and determined it also contained LGD-4033 and GW1516, which were not listed on the label.
