Or it could have been intended to use as a doping scheme utilizating the data from the experiment to stay under the threshold of the T/E ratio. And if this was all part of a doping scheme under the disguise of a "sabotage" concern, I don't why you would be in "shock & awe" that elite runners would use testosterone (and didn't Salazar say androgens could improve a marathon time by 2 minutes or something like that?).
3) The "trafficking" of testosterone -- According to the report, the testosterone experiment, performed on non-athletes, was intended to address a concern of post-race sabotage of NOP athletes. All athletes benefited indirectly from the knowledge that it would take a lot of cream, too much to go unnoticed, for sabotage to trigger a positive.
You've probably been researching PEDs & elite athletes longer than I have, therefore you should know that low-dose testosterone and androgens are the gold standard for recovery and strength with elite endurance athletes. The use of T & androgens has been going on since the 1960s -large number of positives over the decades from mid-d runners up through marathoners. And even the supposedly resilient to injury, superhuman Kenyans are testing positive for T like crazy (e.g., Kimutai, Yator, Wangari, Biwott).
So, I don't why you act like it's implausible that this could be a doping scheme unless Salazar is your idol or something and you couldn't fathom the idea that he could do anything like that.
