Cytomel (Liothyronine Sodium) Profiles by OrtPharmacy

DrugClass: Synthetic thyroid hormone Average Dose: 25-100 mcg/day Comments: Significant suppression of Thyroid function during use

Cytomel is not an anabolic/androgenic steroid but a thyroid hor-mone. As a substance it contains synthetically manufactured liothyronine sodium which resembles the natural thyroid hormone tricodidethyronine (L-T3). The thyroid of a healthy person usually produces two hormones, the better known Lthyroxine (L-T4) and the aforementioned L-triiodine-thyronine (L-T3). Since Cytomel is the synthetic equivalent of the latter hormone, it causes the same processes in the body as if the thyroid were to produce more of the hormone. It is interesting to note that L-T3 is clearly the stronger and more effective of these two hormones. This makes Cytomel more effective than the commercially available LT4 compounds such as L-thyroxine or Synthroid. L-T3 has proven to be 4-5 times more biologically active and to take effect more quickly than L-thyroxine (L-T4)." In school medicine Cytomel is used to treat thyroid insufficiency (hypothyroidism).

Among other secondary symptoms are obesity, metabolic disorders, and fatigue. Bodybuilders take advantage of these characteristics and stimulate their metabolism by taking Cytomel, which causes a faster conver-sion of carbohydrates, proteins, and fats. Bodybuilders, of course, are especially interested in an increased lipolysis, which means in-creased fat burning. Competing bodybuilders, in particular, use Cytomel during the weeks before a championship since it helps to maintain an extremely low fat content, without necessitating a hunger diet. Athletes who use low dosages of Cytomel report that by the simultaneous intake of steroids, the steroids become more effective, most likely as the result of the faster conversion of protein.

To a great extent several bodybuilders who are pictured in "muscle magazines" and display a hard and de-fined look in photos, eat fast food and iron this out by taking Cytomel. The over stimulated thyroid burns calories like a blast furnace. Nowadays, instead of Cytomel, athletes use Clenbuterol which is becoming more and more popular. Those who combine these two compounds will burn an enormous amount of fat.

Cytomel is also popular among female bodybuilders. Since women generally have slower metabolisms than men, it is extremely difficult for them to obtain the right form for a competition given today's standards. A drastic reduc-tion of food and calories below the 1000 caloric/day mark can often be avoided by taking Cytomel. Women, no doubt, are more prone to side effects than men but usually get along well with 50 mcg/day. A short-term intake of Cytomel in a reasonable dosage is certainly "healthier" than an extreme hunger diet.

As for the dosage, one should be very careful since Cytomel is a very strong and highly effective thyroid hormone. It is extremely impor-tant that one begins with a low dosage, increasing it slowly and evenly over the course of several days. Most athletes begin by tak-ing one 25-mcg tablet per day and increasing this dosage every three to four days by one additional tablet. A dose higher than 100-mcg/ day is not necessary and not advisable. It is not recommended that the daily dose be taken all at once but broken down into three smaller individual doses so that they become more effective. It is also impor-tant that Cytomel not be taken for more than six weeks. At least two months of abstinence from the drug needs to follow.

Those who take high dosages of Cytomel over a long period of time are at risk of developing a chronic thyroid insufficiency. As a consequence, the athlete might be forced to take thyroid medication for the rest of his life. It is also important that the dosage is reduced slowly and evenly by taking fewer tablets and -not be ended abruptly. Those who plan to take Cytomel should first consult a physician in order to be sure that no thyroid hyperfunction exists.

Possible side effects are: heart palpitation, trembling, irregular heartbeat, heart oppression, agita-tion, shortness of breath, excretion of sugar through the urine, ex-cessive perspiration, diarrhea, weight loss, psychic disorders, etc., as well as symptoms of hypersensitivity." Our experience is that most symptoms consist of trembling of hands, nausea, headaches, high perspiration, and increased heartbeat. These negative side effects can often be eliminated by temporarily reducing the daily dosage. Those who use Cytomel over several weeks will experience a decrease in muscle mass. This can be avoided or delayed by simultaneously taking steroids. For the most part, since Cytomel also metabolizes protein, the athlete must eat a diet rich in protein. L-T3 can usually be found quite easily. 100 tablets of 0.05 mg each cost approx. $40. It is unlikely that there will be fakes.
