Fat Loss 

Liothyronine is the most potent form of thyroid hormone. Chemically, it is nearly identical to triiodothyronine (T3). As such, it acts on the body to increase the basal metabolic rate, affect protein synthesis and increase the body's sensitivity to catecholamines (such as adrenaline) by permissiveness. The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds. 

T3 is a regulator of the oxidative metabolism of energy. When you take liothyronine sodium it will increase the uptake of nutrients into the mitochondria, which raises activity in the oxidative metabolic pathway. This causes everything to work harder within the organism and makes the body demand more fuel. 

T3 in the body is responsible for regulating the uptake of various nutrients into cells and into the mitochondria of those cells in order to effectively become utilized for the production and consumption of energy.The mitochondria of every single cell in the body utilizes carbohydrates (primarily), fat, and even protein for the production of an energy source known as ATP (Adenosine Triphosphate). Through the intake of more T3, this production of ATP will increase, leading to an increased rate of energy consumption in the form of fats,carbohydrates, and protein. Hence, this is why the consumption of too much T3 without the use of anabolic steroids can result in muscle loss. 


The increase of ATP and metabolic activity leads the body to burn fat. This is why bodybuilders use T3 as a part of their anabolic steroid stacks. Furthermore, T3 is popular among bodybuilders because it can help burn those stubborn 1 to 2% of body fat that won’t come off through just diet and cardio. 

Another interesting property of Cytomel is that it can enhance growth hormone (GH) production. 

Dosages of T3 

In the first approach, the goal is to achieve an ongoing edge in fat loss or to help maintain a near-personally-ideal body composition. In this approach, T3 dosing is very low, preferably 12.5 mcg/day but in some cases as much as 25 mcg/day. At the lower end of this range, typically thyroid testing will show no detectable suppression even with prolonged use. At the higher end, moderate suppression is sometimes seen, but results are superior to when T3 is not taken, and the suppression reverses rapidly upon discontinuing T3 use. 

In the second approach, the goal is to achieve a quite substantial increase in rate of fat loss, at the known cost of inducing thyroid suppression. Most preferably the dosage is about 50 mcg/day, but in some instances can be as high as 75 mcg/day. Such use is preferably not ongoing, but only for a limited period of time such as 8-12 weeks, though there’s no exact requirement for timeframe.
