Cytomel is popularly recognized brand name for the drug liothyronine sodium (LT-3). This is not an anabolic but a thyroid hormone used for "cutting-up" by bodybuilders. Specifically, Cytomel increases the metabolism, resulting in an increased conversion of carbohydrates, fats and proteins. This drug is most commonly used during contest preparation, where one can greatly decrease the amount of stored bodyfat without being forced to diet so extremely. It is also noted by many that when taken in conjunction with steroids an increased anabolic effect is seen over steroid use alone. This is likely due to faster utilization of proteins by the body. One should take caution when considering use, as Cytomel comes with an extensive list of warnings and precautions. One can permanently alter the functioning of their body if this drug is misused.
