Robbie--
You make some good points but when discussing anything that falls under the heading "Performance Enhancing Drugs" what does "use caution" supposed to mean? Either you are using enough of a certain substance to obtain the desire affect or you are not.
I agree with you that one should have their thyroid looked at but there is no empirical evidence stating that liothyronine sodium will permanently down regulate the thyroid. Quite to the contrary, much of what is coming out now says that T3 will offset the thyroid for only a short time (i.e. a few weeks at the most) and that is after extended peiods of time (2 years or more).
Also, the old gurus who began telling people to cycle up and back down off of T3 were mistaken as well. Yet again there is zero evidence that tapering down or out right coming off at the end has any difference.--Penny
