T3 (cytomel) (Liothyronine sodium)

T-3 Cytomel, SB Labs, Bangkok
Chemical name: Thyronine
T-3 Cytomel is not an anabolic/androgenic steroid but a thyroid hor­mone. 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 interesting to note that L-T3 is clearly the stronger and more effective of these two hormones. This makes T-3 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 T-3 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 this product, 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, useT-3  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 T-3 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.
Until recently, T-3 Cytomel was used on a daily basis over several months to remain "hard" and in good shape all year round. The over stimulated thyroid burns calories like a blast furnace. Nowadays, instead of T-3 Cytomel, athletes use Clenbuterol which is becoming more and more popular. Those who combine these two compounds will burn an enormous amount of fat. The next time you read that a certain pro bodybuilder approach­ing a championship competition is still eating 4000 calories a day, you will know why. T-3 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 reduc­tion of food and calories below the 1000 calorie/day mark can often be avoided by taking T-3 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 T-3 Cytomel is a very strong and highly effective thyroid hormone. It is extremely impor­tant that one begins with a low dosage, increasing it slowly and evenly over the course of several days. Most athletes begin by tak­ing 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 impor­tant 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 T-3 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 hyper function exists.
Possible side effects: 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 takingT-3  Cytomel since, especially in the beginning, the effect can be quick and sometimes drastic.

T3 CYTOMEL LIOTHYRONINE SODIUM (UNI-PHARMA) 30 X 25MCG TABLETS
Uni-Pharma Supply: 30 x 25mcg Liothyronine Sodium Tablets
T3 / Cytomel (Liothyronine sodium) is a synthetic form of a natural thyroid hormone, available in tablet form.
T3 / Cytomel is an excellent fat burner because your metabolism is greatly increased while being on it. You can afford to relax somewhat during pre contest dieting since it will still burn fat when you are taking in a lot of calories due to your metabolism still running fast.
T3 is a synthetic thyroid hormone (Type T-3). There are two main types of synthetic thyroid hormones that are available being this and Synthroid (T-4). This product 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).
T3 and the Clenbuterol stack (cycle) is probably the most effective weight loss program.
T3 cycles should never last more than six weeks!
Start with lower dosages 25mcg per day first thing in the morning.
Increase the dosage by 25mcg every 3 to 4 days.
Do not exceed 100mcg per day.
Use T3 in a stack with Clenbuterol (cycle). This stack will give best results when used for weight loss.
