I doubt you are at a point where you need T3. However If you run T3 correctly you will not need more than 50mcg. If you decide you need to go up to 100 or more mcg then you will be more likely do leave your thyroid dependent on it. T3 is no joke. That said, its not going to do anything amazing for you. You would be better off with Dylan's suggestion of Albuterol.
