Product description:


Testagen is a short bioregulatory peptide that has a primary effect on the pituitary gland and, ultimately, on the thyroid gland. You can buy it in our online store. As a result of its effect on these two glands, Testagen is able to normalize the production of testosterone, as well as the production of thyroid hormones under certain conditions. Normalizing the production of thyroid hormones, Testagen has a moderate effect on the immune system. In these cases, Testagen can be conveniently considered as a tool that returns the pituitary gland to a younger state and thus acts as an anti-aging peptide. Testagen is being studied for its ability to increase testosterone levels, improve the function of thyroid hormones, and stimulate the differentiation of stem cells of the immune system to improve immune function.


Testagen

Testagen, as the name suggests, is a bioregulatory peptide that increases testosterone levels. Like many short peptides,
Testagen penetrates both cell and nuclear membranes and directly interacts with DNA. Studies show that Testagen is able to stimulate the anterior lobe of the pituitary gland, increasing the release of thyroid-stimulating hormone and, ultimately, thyroid hormones T3 and T4. It does this even in the absence of pituitary support, which suggests that it directly changes the nature of protein expression in the pituitary gland, and this function can explain its effect on testosterone levels. Finally, since Testagen 20 mg affects the pituitary gland, it affects hemostasis and immunity, although they are less pronounced than its effect on the level of thyroid-stimulating hormone and testosterone.


Testagen and thyroid hormone

The thyroid gland, part of the endocrine system, is important for metabolism, growth and reproductive function. Dysfunction of the thyroid gland can lead to problems with memory and concentration, changes in heart rate, difficulties with regulating body temperature, weight gain, high cholesterol and problems with reproductive function.


One of the many causes of thyroid gland dysfunction is associated with insufficiency of the pituitary gland, the gland that regulates it. In this case, the level of the second hormone, TTg, decreases and does not stimulate the thyroid gland. There are a number of reasons why this can happen, but studies on birds show that the pituitary gland can be stimulated directly, but with the introduction of Testagen 20 mg. Testagen appears to change DNA expression profiles in the pituitary gland, increasing TSH secretion.
Studies show that this leads to near-normal thyroid hormone levels.


Testagen and testosterone level

Research shows that Testagen 20 mg can help normalize testosterone levels and, consequently, testicular function. This may be especially true for older men suffering from low testosterone and related problems, such as decreased bone density, decreased muscle mass, erectile dysfunction, decreased libido, cognitive problems, and decreased energy levels.

It is important to note that the positive effect of using Testagen 20 mg on the pituitary gland can occur even if the dysfunction is caused by tumors, drugs (for example, steroids, morphine), infection and/or autoimmune conditions. Currently, research is in the early stages, so it is difficult to determine the specific conditions under which Tesagen affects or does not affect the pituitary gland.

Some or all of the benefits that Testagen has on testosterone levels may be directly related to its effect on thyroid hormone levels. Studies show that hypothyroidism can lead to a decrease in testosterone, which is subsequently normalized with thyroid hormone replacement therapy. It was also shown that replacement therapy with thyroid hormones normalizes the concentration of free testosterone.
Then it is clear that the positive effect of Testaten on the level of testosterone can actually be connected with its effect on the level of thyroid hormones. In this area, it is necessary to conduct additional research.

Summary of Testagen

Testagen is a short bioregulatory peptide that has a primary effect on the pituitary gland and, ultimately, on the thyroid gland. As a result of its effect on these two glands, Testagen is able to normalize the production of testosterone, as well as the production of thyroid hormones under certain conditions.
By normalizing the production of thyroid hormones, Testagen has a moderate effect on the immune system. In these cases, Testagen can be conveniently considered as a tool that returns the pituitary gland to a younger state and thus acts as an antiaging peptide.
Testagen is being studied for its ability to increase testosterone levels, improve the function of thyroid hormones, and stimulate the differentiation of immune system stem cells to improve immune function.

Testagen shows minimal side effects, good oral and excellent subcutaneous bioavailability in mice. The dosage per kg for mice does not apply to humans. The sale of Testagen at Peptide Sciences is limited to educational and scientific research and not for human consumption. Buy Testagen only if you are a licensed researcher.
