Going from the Mark Lewis topic its probs better over here.
Again my knowledge in this area is very poor. But as far as my limited reading I’ve done goes. Any kind of TRT is banned via WADA and UKAD. Unless I’m mistaken so I can’t see how that statement is true? I can only presume it slips by via the, no testing in this sport so its legal. Eg if he competed in a triathlon, banned. Hyrox, Ultra marathon (maybe not all are UKA sanctioned?) Parkun fine? But when does TRT become sport performance? Seems like a massive grey area.
Would boosted test levels significantly improve pure running performance? Again he mutes that it doesn’t but surely even from a improved recovery perspective its going to be hugely beneficial.
