Does clen use lower your natural thyroid production??

I sited a study in an article that I wrote for Muscle Mag International a couple years ago on T3, that showed that thyroid levels were lower after 4 weeks of clen. However I'm not convinced that it was solely due to clen usage as everyone knows that dieting for 4 weeks will lower your thyroid levels as well. The jury's still out on this one....
