Cytomel is not an anabolic/androgenic steroid but a thyroid hormone and is used to treet people who are hyperthyroid. These people suffer many problems such as fatigue, obesity, and other ailments. As a substance it contains synthetically manufactured liothyronine sodium which resembles the natural thyroid hormone Tricodide-thyronine (L-T3). The thyroid of a healthy person usually produces two hormones, the better known L-thyroxine (L-T4) and the aforementioned L-trilodine~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 used by bodybuilders to increase their metabolic rate. If all goes well, the cytomel will increase the metabolism of carbohydrates, lipids, and proteins. This means the athlete�s body will use that more efficiently. This is the most sought after effect of the cytomel by bodybuilders. When they use this drug, they can get ripped up on a much higher calorie diet. In fact, there is even some evidence to support the premise that the steroids an athlete is using will be better utilized by the body if cytomel is taken at the same time. This is due in part because the cytomel increases protein metabolism.

The thyroid hormone in this drug is a synthetic hormone available as the sodium salt which is normally used by the human thyroid gland. Cytomel does increase protein metabolism when it is taken in small dosages. One tablet is equal to approximately one grain of natural thyroid hormone. The dosage should only be taken for about a month to avoid serious adverse reactions. This drug has been very popular with women bodybuilders. They naturally have a lower metabolic rate and often must go as low as 500 calories a day for several weeks before they get really ripped. If they can handle a dose of 25 mcg of cytomel they can eat at least twice as much while they are on a pre - contest diet. This would actually be healthier than starving like many women lifters do.

Taking to much will will result give you hyperthyroidism. Symptoms of hyperthyroidism may include: a severe headache, irritability, nervousness, insomnia, sweating and menstrual irregularities.

There are two main types of synthetic thyroid hormones that are available, T3 and Synthroid (T-4). Cytomel is a synthetic thyroid hormone (Type T-3) and is regarded as the stronger of the two products (it is 4-5 times stronger than Synthroid). This product works by increasing the synthesis of protein, carbohydrates, and fats as well as RNA in the body thereby increasing your BMR (Basal Metabolic Rate).

Step over Ripped Fuel, E/C/A stack, Thermodrine. When taken with clenbuterol, this is the single best fatburning combination that is available today (with the possible exception of DNP). I am not too big on death or a coma either though.

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 L-T4 compounds such as L-thyroxine or Synthroid. The manufacturer of the German L-T3 compound, Hoechst AG, ascribes the following characteristics to its Thybon drug, making it clear that L-T3 is superior to L-T4: "The synthetically manufactured thyroid hormone, L-trilodine-thyronine (L-T3), included in Thybon, in experimental and clinical testing 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 conversion of carbohydrates, proteins, and fats. Bodybuilders, of course, are especially interested in an increased lipolysis, which means increased 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.

Possible side effects such as medication are described in the package insert by the German pharmaceutical group Hoechst AG for their compound Thybon: "Exceeding the individual limits of compatibility for liothyronine or taking an overdose, especially, if the dose is increased too quickly at the beginning of the treatment, can cause the following clinical symptoms for a thyroid hyperfunction): heart palpitation, trembling, irregular heartbeat, heart oppression, agitation, shortness of breath, excretion of sugar through the urine, excessive 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. Caution, however is advised when taking Cytomel since, especially in the beginning, the effect can be quick and sometimes drastic. Athletes do not use the injectable version of L-T3, this is normally used as "emergency therapy for thyrotoxic coma." 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

Also, if you are taking insulin at the same time you are taking this product, keep in mind that it will reduce the effectiveness of insulin or any oral insulin products as well such as metformin or phenformin. Just remember that this product will work best on a steroid cycle and you need to keep your protein intake very high since this product metabolizes protein as well.
