T-3 (Liothyronine Sodium) is not an anabolic steroid but a thyroid hormone. It is used medically to treat cases of thyroid insufficiency, obesity, certain metabolic disorders and fatigue. Specifically this drug is a pharmaceutical preparation of the natural thyroid hormone triiodothyronine (T-3). When administered, T-3 (Liothyronine Sodium) increases the patient's metabolism. The result is an increased rate of cellular activity (noted by a more rapid utilization of carbohydrates, fats and proteins). Bodybuilders are particularly attracted to this drug for its ability to burn off body excess fat.

Most often utilized during contest preparation, one can greatly decrease the amount of stored fat without being forced to severely restrict calories. To this end T-3 (Liothyronine Sodium) is commonly used in conjunction with Clenbuterol and can produce extremely dramatic results. This combination has become very popular in recent years, no doubt responsible for many "ripped" on-stage physiques. It is also noted by many that when thyroid hormones are taken in conjunction with steroids, an increased anabolic effect can be seen. This is likely due to faster utilization of proteins by the body, increasing the rate for new muscle accumulation.

One should take caution if considering using this drug. T-3 (Liothyronine Sodium) comes with an extensive list of warnings and precautions which are not to be ignored. Side effects include, but are not limited to, heart palpitations, agitation, shortness of breath, irregular heartbeat, sweating, nausea, headaches, and psychic/metabolic disorders. It is a powerful hormone, and one that could potentially alter the normal functioning of the body if misused. When administering T-3 (Liothyronine Sodium), one must remember to increase the dosage slowly.

Generally one 25mcg tablet is taken on the first day, and the dosage is thereafter increased by one tablet every three of four days for a maximum dosage of 100mcg. This will help the body adjust to the increased thyroid hormone, hopefully avoiding any sudden "shock" to the system. The daily dose is also to be split evenly throughout the day, in an effort to keep blood levels steadier. Women are more sensitive to the side effects of T-3 (Liothyronine Sodium) than men, and usually opt to take no more than 50mcg daily. It is important to stress that a cycle should last no longer than 8 weeks and it should never be halted abruptly. As slowly as the dosage was built up it should also be lowered, one tablet every 3-4 days. Taking T-3 (Liothyronine Sodium) for too long and/or at too high a dosage can result in a permanent thyroid deficiency. After doing such, one might need to be treated with a drug like T-3 (Liothyronine Sodium) for life. It is also a good idea to first consult your physician and have your thyroid function tested.
