Liothyronine Sodium
Liothyronine Sodium is a synthetic form of the thyroid hormone triiodothyronine (T3) used to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormones. It is also prescribed for managing thyroid hormone imbalances, including certain cases of goiter and thyroid cancer. In fitness and bodybuilding, Liothyronine Sodium is sometimes used to boost metabolism, promote fat loss, and enhance energy levels, especially during cutting cycles.

It works by increasing the metabolic rate, improving protein synthesis, and accelerating fat breakdown, which can lead to faster weight loss and improved muscle definition. However, misuse can cause serious side effects such as heart palpitations, anxiety, excessive sweating, muscle loss, and thyroid suppression. Long-term or high-dose use may lead to thyroid gland dependency, requiring careful dosing and gradual discontinuation. Regular monitoring of thyroid levels and overall health is essential to minimize risks when using Liothyronine Sodium for performance enhancement.
