Jose Canseco refused to provide a urine sample for steroid testing in Mexican Baseball League

Jose Canseco, a former player of the Major League Baseball, didn’t agree to submit to a urine analysis for steroids, when he tried to return to the Mexican Baseball League. It was earlier reported that the “Tigres de Quintana” of Cancun provided him the 2nd  chance and invited him to play.
Jose Canseco didn’t agree to submit to tests for steroids that had to be conducted by officers of the Mexico’s National Commission for Physical Culture and Sport (CONADE). CONADE is government agency that manages Olympic sports in Mexico.
Cuauhtemoc Rodriguez Meza, the chief executive officer of this baseball team, proclaimed that Jose Canseco would not be permitted to play for the team because he had admitted that he administered forbidden medicines.
Jose Canseco acknowledged that he was on testosterone replacement therapy under supervision of a physician in the US. He mentioned that he was on TRT since 2008. Jose Canseco was not surprised by the requirement to submit to steroid testing. This person wrote on his Twitter account last month that the Minor League Baseball would perform testing for forbidden products.
It is known that  an athlete can utilize steroids for TRT and take part in competitions, if he/she has got a therapeutic use exemption (TUE). A TUE allows administration of banned drugs, if it is justified by medical needs.
It is obvious that Jose Canseco has prescription from his doctor that supports his condition which requires receiving TRT. But Jose Canseco doesn’t have any TUE for usage of testosterone.
Canseco has openly admitted that he had a prescription from his physician to use testosterone as a part of testosterone replacement therapy. He noticed about  this condition in a documentary in 2008. Jose Canseco noticed that he discontinued applying illegal steroids and had hypogonadism which was caused by steroids. Then his doctor prescribed him applying a testosterone gel to be relieved from unwanted effects of steroids.
As you see, Jose Canseco’s usage of steroids is justified because he has medical need for application. But since he hasn’t got a TUE, it is unclear whether he would join the team that has steroid testing.
The CEO of “Tigres de Quintana” affirmed that he had known that Jose Canseco was receieving TRT but he invited him to play, just obtaining a TUE.
