Combining Growth Hormone, Triiodothyronine, and Thyroxine

Growth hormone stimulates the conversion of the inactive thyroid hormone, thyroxine (T4), into the biologically active triiodothyronine (T3).

Triiodothyronine increases the metabolic rate and directly affects the breakdown of fat cells, significantly accelerating the process of lipolysis.

Application of Growth Hormone in Combination with T3

Sustained high levels of growth hormone in the blood lead to a reduction in the production of thyroxine, and this decrease occurs one week after the start of injections.

Therefore, theoretically, there will be fewer triiodothyronine molecules in the blood than at the beginning of the growth hormone course.

The concentration of growth hormone in the blood increases the number of T4 molecules, transforming into T3 molecules under the influence of the activity of the 5'-deiodinase enzyme, stimulated by somatotropin.

As a result, the level of triiodothyronine remains almost unchanged, even with a significant decrease in thyroxine levels, at least during the first 4 weeks of the growth hormone course.

The maximum period during which T3 actively participates in the "burning" of fat rather than muscle is limited to three weeks.

Therefore, it is recommended to stop using T3 after three weeks. However, it is essential to consider that after discontinuation, the concentration of triiodothyronine in the blood plasma will significantly decrease, which is related to the factors mentioned earlier.

Dosages of Triiodothyronine (T3)

To overcome this situation, you can use a low dosage of T3, up to 25 mcg. At this dose, it can be taken for an extended period without concerns about potential side effects.

However, in this case, the effectiveness of triiodothyronine for "burning" fat will significantly decrease.

Application of Growth Hormone in Combination with T4

As an alternative, considering additional intake of T4 is an option.

In this case, the key point is the precise determination of the necessary amount of thyroxine. It is important to maintain a balance between insufficient and excessive levels.

Dosages of T4 When Using Somatotropin

It is advisable to start with 50 mcg every other day, gradually increasing the dose to 100 mcg daily, especially if growth hormone injections are used daily.

It is crucial to monitor your condition carefully and avoid crossing the threshold beyond which not only fat but also muscles start to "burn." Finding the optimal dosage will require a series of experiments.

All interventions aimed at correcting thyroid hormone levels should be introduced only from the fourth or even fifth week of growth hormone use.

Conclusion

It is believed that these actions aimed at regulating the hormonal balance of the thyroid gland are not mandatory.

They are justified only when striving to reduce body fat to extremely low values beyond ordinary limits. Or perhaps if your thyroid gland synthesizes a small amount of thyroxine.

In cases where the thyroid gland is functioning normally, thyroid hormones can provide certain support for growth hormone, but they can be omitted entirely.

Sometimes it makes sense to include small doses, for example, 25 mcg of triiodothyronine, in your pharmaceutical arsenal, even if you don't care too much about the "burning" of fat.

Such doses of T3 can positively affect protein metabolism, which is undoubtedly essential.
