T3 Cytomel, supressing you natural Thyroid? I just read an old article in an 1978 bodybuilding magazine. They were discussing the use of t-3 and siad how bad the stuff was and how it would shut down the producation of Thyroid hormone permently... I baught some t-3 back in the 1990s and read how it would make you loose 20 lbs.. then when you got off you would gain 35 back.. so I gave it away. I recently started taking it while trainning for a bodybuilding contest. I'm ready to get off but now I'm worried that I might have slowed my matabolism down. What do you guys think? I was only onn it for about 6 week and I worked up to 75mcgs. I have recently researced t3 and they dont seem to be worried about the negitive effect of it as much. I would like to switch to adipex or ECA for a few weeks but it does not seem to be around like it was at one time. any thought of what I should do or the safty of t-3
