Liothyronine Sodium is a synthetic variant of the human body’s own thyroid hormone. Within a medical and clinical setting, Liothyronine Sodium is utilized in the treatment of hypothyroidism, which is a condition whereby an individual’s thyroid gland is not secreting the proper and normal levels of thyroid hormone for proper function. In such a case, hypothyroidism is commonly diagnosed via a blood test that analyses the serum hormone profile of thyroid hormones (T3, T4, and TSH, which is Thyroid Stimulating Hormone).

Hypothyroidism also carries with it various symptoms such as a lack of energy, lethargy, weight and fat gain, hair loss, and alterations in skin colour and texture. T3 is the primary thyroid hormone used by the body.

Cytomel is a different type of compound as it is not an Anabolic steroid, nor is it a Sarm or any other category of substance that is commonly used by bodybuilders or athletes. It is a synthetic form of a thyroid hormone called T3/Tertroxin, or triiodothyronine, which is produced naturally in the body. The synthetic form is known as Liothyronine Sodium, with T3 being the brand name.

This synthetic T3 is very similar to the original triiodothyronine hormone, but not the same. Small variations of the chemical structure have resulted in T3 having a high rate of oral absorption and an increased level of potency.

The bodybuilding and athletic world are attracted to the use of T3 as a physique and/or performance enhancing drug because of its capability to distinctly boost the body’s metabolism in the effort to metabolize body fat at a greater rate. T3 is traditionally utilized during cutting, dieting, and/or pre-contest phases of training due to the universal goal of these phases to break down body fat, though in recent years Liothyronine Sodium has gained some popularity as a useful agent during bulking and mass gaining phases of training (normally in conjunction with anabolic steroids) in order to better efficiently process nutrients and/or to keep body fat levels down during periods of higher caloric intake.
Liothyronine Sodium is commonly used with anabolic steroids due to its significant impact on the body’s metabolism. It is very important to understand that T3 is indiscriminate in its metabolism boosting properties – it will increase the metabolism of fats, carbohydrates, and protein all equally. Therefore, beyond a particular dose of T3, there is an increased risk of muscle loss through increased turnover of protein. Using anabolic steroids and a properly adjusted diet, this muscle loss because of T3 can be prevented because of the nitrogen-retaining and protein sparing properties of the anabolic steroids.
Liothyronine Sodium is also commonly combined with other fat loss agents to increase its overall effect, as it does work synergistically with other fat loss agents. Some of these include Ephedrine, Clenbuterol, Human Growth Hormone (HGH) as well as other fat burning agents.
