Abnormal kidney function defined as creatinine \>1.3mg/dL. Abnormal liver function tests within 1.5x ULN. UCH Clinical Lab ULN for AST and ALT are 39 and 52, respectively. Individuals with TSH levels outside of the normal range (0.5-5.0 mIU/mL) will be referred to their PCP and will be allowed study entry once their TSH levels are normalized \> 2 months; * Current medical insurance; for safety.
