The Nevada State Athletic Commission ruled Thursday to discontinue awarding Testosterone Replacement Therapy (TRT) exemptions to fighters who are diagnosed with low testosterone.
A controversial issue in mixed martial arts, TRT has raised red flags due to the ease at which competitors are able to cheat tests that diagnose the disorder.
The ban not only includes future users, but those currently with exemptions to take advantage of the procedure.
The Ultimate Fighting Championship weighed in shortly after word came down Thursday.
“The UFC fully supports the decision made today by the Nevada State Athletic Commission regarding the immediate termination of therapeutic use exemptions for testosterone replacement therapy,” UFC president Dana White said in a statement.
The UFC also said it intends to honour the ruling while staging shows internationally.
“We believe our athletes should compete based on their natural abilities and on an even playing field," White said.
“We encourage all athletic commissions to adopt this ruling."
