I'm on 88 mcg of levothyroxine, and curious what t3 would do to me along with it. I have no side effects from the t4, but I am on the LOW side. Need to bring this up with my doc. Someone please chime in on what t4+t3 at the same time can do to you. T4 kept my levels normal, but just barely in the range and I cant lose weight to save my life. I'm trying to cut a bit and even with a major drop in calories and cardio nothing shines improvement. I'm considering t3 especially if my doc declines. need advice please.
