Product Description


Pharmacological action of the drug Levothyroxine sodium:

T4 (Levothyroxine Sodium) is a drug from the group of hormones of the thyroid gland. The drug replenishes the deficiency of thyroid hormones through receptor binding of the active substance to the genome, changes in oxidative metabolism in the mitochondria, and regulation of the flow of substrates and cations outside and inside the cell. In small doses of levothyroxine sodium has an anabolic effect, in medium doses stimulates growth and development, increases the need for tissues in oxygen, regulates the metabolism of proteins, fats and carbohydrates, increases the functional activity of the cardiovascular system and the central nervous system. In large doses, the drug inhibits the production of thyrotropin-releasing hormone of the hypothalamus and thyroid-stimulating hormone of the pituitary gland. Levothyroxine sodium belongs to the group of hormonal drugs.

T3 (Liothyronine) is a common name for a number of medical medicines. Their direct purpose is the regulation of the thyroid gland , and with it the metabolism, which is a very important aspect of the athlete’s success. When preparing for competition, Lytryronin is very often used by professional bodybuilders as a means of losing weight. Unfortunately, for the same purposes it is used by ordinary people, which quite often leads to disastrous consequences


The main purpose is to stimulate the production of thyroxine, the main hormone of the thyroid gland. In the human body it is quite enough, but the whole problem is that this hormone is rather inactive. The drugs also contain a special enzyme that turns it into a more active form, Triiodothyronine. Of course, you can first apply and T4, that is, drugs containing exactly thyroxine, but they are noticeably weaker. Therefore, as a rule, it is products of the Liotironin type that are used in professional sports in drying courses. Lyotironinovye drugs in their effectiveness exceed all existing for burning fat.

The main positive properties:

  • fat burning
  • central nervous system stimulation
  • suppression of appetite (it is appreciated precisely on drying courses)
  • increase of efficiency

How to apply

Calculating the rate of Lytryronin is strictly individual and often does not depend on the individual factors of the athlete, but on the drug itself. This drug is unstable, its activity is greatly reduced over time. Therefore, all further figures regarding the course will be very approximate.

There are two approaches to taking this drug. The first is the constant use of T3 in order to stabilize the burning of fat masses and to go to the goal gradually, at a small pace, or to support oneself in the ideal form. In this case, a dosage of 12.5 mg is sufficient, although in rare cases 25 mg are used. The second way is coursework. Higher doses of the drug are used here for a certain, short enough period of time to minimize the harmful effects. In this case, the athlete takes no more than 75 mg daily, although usually less than 50 mg. The course lasts from eight to twelve weeks.

Side effect

The side effects of taking Triiodothyronine are mainly associated with non-compliance with the instructions and taking too high doses. Excessively high dosages of this drug can seriously disrupt the hormonal balance. Before the start of the course, it is best to familiarize yourself with all possible negative consequences.

  1. Catabolic effects, decrease in anabolism. In combination with powerful steroids, there is not such a serious effect, ligaments with the same “methane” compensate for this effect.
  2. Tachycardia and high blood pressure. This effect is manifested in the use of dosages bordering on safe.
  3. Nervous breakdown. Lyotyronin stimulates the nervous system and high dosages can seriously shake it.


Lytryronin is quite possible and even should be used in combination courses. So, to neutralize some of the side effects, it should be used together with steroids that have a high anabolic index. There is also a remarkable combination of clenbuterol, lyotyronine and yohimbine, which largely affects the fat burning process.
