T-3 Liothyronine Sodium is a Fat Burners thyroid hormone drug that is quite popular for losing fat, especially in the context of cyclic anabolic steroids. T3 is produced naturally in the body as a result of the thyroid (T4) (thyroxine) produced by the thyroid. Drinking of T3 may bring about a higher level of serum T3 than it would naturally occur, allowing for faster fat loss and in some cases producing GH potentially greater and greater than anabolism.
