Fusion Cytomel (Liothyronine Sodium T3) is a synthetic form of T3 thyroid hormone. It has the chemical designation I-tyrosine,o-(4-Hydroxy-3-iodophenyl)-3,5-diiodo-L-tyrosine.
Bodybuilders and athletes are attracted to liothyronine sodium for its ability to increase metabolism and support the breakdown of body fat. Most often utilized during contest preparations or periods of “cutting”, the drug is usually said to significantly aid in the loss of fat, often on higher levels of caloric intake than would normally be permissive of such fat loss. The usual protocol among among bodybuilders and athletes taking the drug involves initiating its use with a dosage of 25mcg per day. This dosage may be increased 25mcg every 4 to 7 days, usually reaching a maximum of no more than 75mcg per day. The intent of this slow buildup is to help the body adjust to the increasing thyroid hormone levels, and avoid sudden changes that may cause side effects. This drug should not be halted abruptly, instead, it is discontinued in the same slow manner in which it is initiated. This tapering is done so that the body has time to readjust its endogenous hormone production.
