I ve done the analysis of hormones and the TSH-reaultatet 8.9 mlU / L, T3-1.3 ng / mL, T4-9.3 Ug / dL. I used letrox 75 mg for a month, and values-TSH 7.4 , T4-10.1 , T3-1.2. My doctor has suggested the use of 100 mg letrox up examination after 2 months. Analysis of proclantin 21.6 ng / mL. My doctor suggested to use bromergon tablet.
