I certainly wouldn't say this thread is useless. Given their assocation with Dr. Brown, I think many fans of the sport think NOP when they hear the word thyroid.
Without a Wall St Journal article hyping their association with thyroid meds, most people wouldn't even know about the issue.
People still don't know about it.
The common misconceptions are that it is prescribed to fight over-training. That's not true; while some symptoms of over training mirror symptoms in over training, fixing thyroid isn't going to fix fatigue.
More, people think that there is a performance enhancing effect: while not directly studied, clinical hyperthyroidism (which would be the effect of a regular person supplementing with extra thyroid) shows that the stimulant effect counters recovery: higher heart rate, blood pressure, changes in anxiety and ability to sleep/rest. If is not catabolic, something that would produce extra energy.
The closest categorization as a PED would be as the cousin of a masking agent: it works to correct imbalances caused by other hormone supplementation, like HGH and EPO. That's the conclusion to draw.
If the drug, by itself, was as powerful as people though it was, it would be banned. By itself, it is not a performance enhancer. Think about it like break fluid: it doesn't make your car go faster, but you certainly need it if you want to drive for a while. Dopers don't take thyroid because of a performance enhancing effect (there is none) they do it to sustain the other pieces of their doping program.
