Cytomel (T3) is rarely prescribed on its own to address thyroid problems; it is usually prescribed with T4. In the past, cytomel was a scheduled treatment for obesity; however, an increase in heart complications and cardiac stress forced withdrawal of T3 for that application.
Because it supplies the body with both T3 and T4 hormones the body no longer needs to convert T4 in order to produce a supply of T3 hormones. Armour Thyroid is also effective and produces fast and consistent results as reported by many users.
