This post is just of general interest and does not have much relevance to our day to day thyroid issues.
Sorry to quote this paper but I couldn't readily find another source of the story.
REVEALED: UK Athletics chiefs' held mystery meeting on controversial use of thyroid medication in 2014
• In 2014 UK Athletics called a special meeting with the English Institute of Sport
• The key topic was the controversial use of thyroid medication on elite athletes
• At the time Alberto Salazar, now banned for doping offences, was a consultant
• Thyroxine is not banned and does not require a therapeutic-use exemption

Goes on to mention:
… prescribing excessive and dangerous levels of prescription vitamin D…
Is this going to be another reason to clamp down on thyroid hormone prescribing? (Article mentions Cytomel by name as well as thyroxine.) I imagine: "You don't need it because you are not, and never will be, an elite athlete."
In part of the same story:
Tygart told the Mail on Sunday in October; 'One athlete [previously coached by Salazar] has to stay on thyroxanol [a thyroid drug] for the rest of their life because they were put on it wrongly and it altered their thyroid system and they now can't ever be off the drug. We have to ensure that the medicalisation of sport does not become commonplace.'
I checked Thyroxanol and found this description of its contents.

Looks to me as if someone has mis-reported something. It reads as if Thyroxanol is a thyroid hormone - which it is not. I can't see any ingredient (or combination) which would require taking it lifelong. I'll not speculate what is the real story.
In common with so many so-called thyroid formulas, the actual iodine content is not clear. Although it appears to say how much iodine there is, it then qualifies that as being from kelp - but there is bladderwrack as well (far more than there is kelp). So it simply does not add up.
