Enhancing anabolism with triiodothyronine (T3)

There are a number of other hormones that can also affect muscle growth besides the famous class of androgenic- anabolic steroids. Human growth hormone, insulin-like growth factor, and insulin have long been known for their roles in increasing muscle mass.

These hormones are synergic one with another, and if only one of them is in short supply, this can lead to difficulties in recruitment of muscle mass. There is another class of hormones, without which the growth of muscle mass is simply impossible, we will talk about thyroid hormones. Bodybuilders have long used thyroid drugs for drying during the preparation for a competition, but few consider these drugs are individuality increase the rate of muscle growth. The close relationship between metabolism and thyroid hormones has long been recognized by all. Hypothyroidism – a condition in which an insufficient amount is formed in the human body thyroid hormones, which leads to loss of appetite; muscle weakness, fatigue, as well as weight gain and low body temperature.

On the other hand, there is also hyperthyroidism, in which too much thyroid hormones are produced. This leads to weight loss, anxiety, and an increase in body temperature. These two extremes clearly show the full power of the influence of thyroid hormones on metabolism dianabol injectable.

Many have heard of the thyroid gland, but not everyone knows what it is for. The thyroid gland is a very sensitive gland, it regulates many processes in the human body. This gland is located at the top of the neck and produces only a few hormones that are critical in how a person looks and feels.

Among the hormones there is a substance called thyroxine, or tetraiodothyronine , also known as T 4 . For the most part, the effect of T 4 is indirect, since most of it will subsequently be converted to triiodothyronine , or T3, which is the more physically active of the two. Not all of the volume of T 4 immediately turns into T3, part of it remains as a reserve for future transformation.       

Thyroid hormones have the potential to be both anabolic and catabolic. Many bodybuilders get burned when they make a mistake in choosing the dosage of thyroid hormones, they use too much of them. This mistake is a common cause of excessive muscle atrophy, and the athlete ends up on stage in a much worse shape than he could.

Thyroid hormones have been used by bodybuilders for decades during the drying cycle. There has never been a question about the ability of thyroid hormones to reduce body fat, but they have not received enough attention in terms of their ability to increase muscle gain.

At low dosages, T3 creates an anabolic environment conducive to muscle growth. It also acts on the liver, in such a way that the liver itself begins to more actively destroy glucocorticoids produced by the adrenal glands, such as cortisol, which can lead to the destruction of the protein structure. Growth hormone is essential in fat metabolism, joint regeneration and muscle repair. Growth hormone is vital to many of the processes that take place in the body. After about 25 years, endogenous growth hormone production begins to decline significantly. 

Many endocrinologists who are serious about hormone replacement therapy have recognized the importance of growth hormone in replacement therapy. I believe that growth hormone can create an additional anabolic environment only when testosterone levels are within the normal range and T3 is taken separately. The practically absent effect of growth hormone on muscle growth itself is due precisely to the lack of thyroid hormones. T3 has the potential to make it both anabolic and catabolic. It all depends on the dosage chosen by the athlete. Many of those who used T3 reported at least only mild catabolic effects.  

T3 has a half-life of approximately 60 hours. This means that when taking 25 μg of substances, 12.5 will be active after another two and a half days. This can lead to an increase in blood levels quickly enough. Already after 4-8 weeks of human use of the thyroid hormone, one can observe the development of a fairly strong catabolic effect cytomel

Thus, knowing the half-life of T3 at 60 hours, this must be taken into account. To achieve a truly anabolic effect from T3, you only need to take 25-50mcg of the hormone every third day. Only 20% of T3 is produced by the thyroid gland itself. The rest is formed from T 4 . The conversion process itself takes place in tissues such as the liver, heart, muscles and the central nervous system. Thyroid hormones are a determining factor in basal metabolism, which is very important for bodybuilders. The more thyroid hormones that are present and active, the more calories the body will burn, particularly in the form of heat.
