As someone who's been into weightlifting and only casual observer-like in regards to testosterone therapy, this doesn't seem to make a lot of sense. After taking TRT/Steroids a person retains a good deal of the muscle/strength they gained even after cessation ... It surprises me to hear that this wouldnt carry over to sports where muscle/strength/power matter.
Additionally, you have to realize that a major concern on the right is that academia itself has become ideological to the point where only politically acceptable studies can be 1) studied and more importantly 2) published. There's a lot of people out there afraid to speak what appears to them (and their work) to be truth for fear of the backlash and career consequences.
