Hi ,,, my recent tsh says 3.3 range 0.3 to 5.2 .... Doc says well done I'm in middle of normal range... But its hardly improved since increasing dose to 50s. Used to be on 25 s, then went to alternate 50,25. Felt great to start when my dose was increased to 50 s couple months ago but now feel like I'm struggling a bit again, esp after exercise I'm gym. I'm bit surprised at the small change in tsh , used to be 4.2 on 25 s ... I'm thinking I needed higher dose.... Am I right? Thank you !
