I felt extremely weak and flat on it. I also think it is completely unnecessary and the people who continue to use it really have no idea how to diet properly. I have only used it once and I realized that I do not really need it. T3 should really only be used on cycle since it burns muscle as well. If you are on AAS and taking T3, then I am pretty sure you are full on cutting. In that case, get your diet right, you do not need T3. When on a strict cut on AAS there is no reason you cannot get into single digit bodyfat without T3 unless you really have no idea what you are doing, which, in that case, you should not be touching these drugs in the first place.
