Jose Canseco has medical needs to be on TRT but he doesn’t have a TUE which allows to play professionally

Jose Canseco rejected to submit to a urine analysis for steroids, when he tried to return to the Mexican Baseball League. It was earlier confirmed that the “Tigres de Quintana” of Cancun gave him the second chance and invited him to play.
Jose Canseco refused to submit to testing for steroids that had to be done by officers of the Mexico’s National Commission for Physical Culture and Sport (CONADE). CONADE represents government agency that manages Olympic sports in Mexico.
The CEO of the “Tigres de Quintana”  Cuauhtemoc Rodriguez Meza claimed that Jose Canseco would not be allowed to play for the team because he had acknowledged that he used banned substances.
Jose Canseco admitted that he was on testosterone replacement therapy under supervision of a physician in the US. He claimed that he was receiving TRT since 2008. This player was not surprised by the requirement to submit to steroid testing. This sportsman wrote on his Twitter account last month that the Minor League Baseball would have testing for forbidden preparations.
As it is known,  a sportsperson may utilize steroids for TRT and participate in competitions, if he/she has obtained a therapeutic use exemption (TUE). A TUE allows administration of banned substances, if it is supported by medical needs.
It is obvious that Jose Canseco has prescription from his health care provider that confirms his condition which requires being TRT. But he hasn’t obtained a TUE for application of testosterone.
Canseco has publicly reported that he had a prescription from his doctor to apply testosterone as a part of testosterone replacement therapy. He reported about  this factor in a documentary in 2008. Jose Canseco claimed that he stopped applying illegal steroids and had low testosterone production that was provoked by steroids. Then his physician recommended him administering a testosterone gel in order to escape from undesirable results of steroids.
You observe that Jose Canseco’s usage of steroids is justified because he has medical support for usage. But since he hasn’t obtained a TUE, it is not clear whether he would play in the team that has testing for steroids.
The CEO of “Tigres de Quintana” noticed that he had known that Jose Canseco was on TRT but he invited him to play, just obtaining a TUE.
