Doctor, do you disagree with this
Steve Magness:
"Up until now, I’ve gone over the traditional route to thyroid disease. Now I want to delve into the 'what if' scenario. What happens if you take thyroid and you don’t need it and how could athletes potentially abuse it?
But I heard bodybuilders use it, so it must enhance performance!?
In the bodybuilding world they apparently use thyroid to cut weight because of the effects it has on metabolism.(How’d I learn bodybuilders use it…google) They essentially put themselves in a hyper state for a short time to cut fat. I have no idea why/how, but again this seems like a horrible idea. First off a runner would be sacrificing recovery (you recover worse in hyper state), and most runners are lean enough.
But the REAL reason bodybuilders and people use it is simple. It’s NOT to enhance performance.
It’s because taking Testosterone and/or HGH severely impacts the thyroid, making you temporarily hypothyroid.
You can see that in the two studies below.

Both studies found that with taking either testosterone or HGH, your TSH levels were elevated. So in order to keep order in their hormonal systems they took thyroid. In fact, look towards Major League Baseball and you can find an incidence of this in 2010.

(Also, note in that article that in 2010 WADA already looked into thyroid as performance enhancers. It’s 2013. It’s safe to say at that time they found just what they said in the WSJ article.)
So, that’s the reason your local steroid junky football player might take thyroid…because testosterone or HGH made him hypothyroid.
Interestingly, if you followed the Floyd Landis case, you know he was taking synthetic thyroid. I don’t know the details, but it makes sense because he was also on a drug program that included EPO, testosterone, and who knows what. My bet is his drug taking knocked him into hypothyroid status."
