Testosterone Undecanoate: How It Works

The active form of Testosterone Undecanoate is the side-chain cleavage product. The active form, testosterone, is formed by cleavage of the side chain. Testosterone is synthesized mainly in the testes and, to a lesser extent in the adrenal cortex is the most important androgen in the male body. Testosterone has predominantly androgenic (e.g., prostate, seminal vesicles, epididymis) or protein-anabolic (muscle, bone, hematopoietic system, kidneys, liver) effects, depending on the target organ. In some organs, the effects of testosterone occur after it has been converted in peripheral tissues to estradiol, which may bind to estrogen receptors in the nucleus of target cells (such as the pituitary gland, adipose tissue, brain, bone and Leydig cells of the testis).

Usage of Testosterone Undecanoate

If we look at the effects of these two drugs, we can see that they are almost the same, and that Undecanoate is not better, but it is also not worse. Both are long-acting, oil-based and available as injections. These characteristics of the drug mean that a high concentration of the active ingredient can be kept in the body for about 2 weeks. The reason for this is that the ester contains fewer carbon atoms (there is only one carbon atom difference), so the shorter the ester, the shorter the action time. In practice, however, the difference in duration of action is not that significant. Therefore, price rather than the difference in potency is more likely to influence the choice between the two drugs. Doping tests can detect the use of this drug for about four months after its last use.

Main Advantages of Testosterone Undecanoate

Why do bodybuilders buy Testosterone Undecanoate? Several factors contribute to muscle mass and strength, including Testosterone. Increased levels of neurotransmitters, which are biologically active chemicals involved in the transmission of electrical impulses from one nerve cell to another, proliferate in the tissues. Among the additional advantages are the following:

• red blood cell count;
• hemoglobin level;
• body weight.

Testosterone Undecanoate works in the following two ways: it interacts with nuclear receptors in the DNA that stimulate the synthesis of proteins. It also levels up growth hormones, so it builds muscles.

Possible Side Effects of Using Testosterone Undecanoate

Undecanoate should be injected intramuscularly, accurately, and very slowly (over 2 minutes), as with all oil solutions. Rarely, administration of oily solutions may cause pulmonary micro embolism, which may result in symptoms such as:

• cough;
• anxiety;
• dyspnea;
• general malaise;
• hyperhidrosis;
• chest pain;
• dizziness;
• paresthesia;
• fainting.

These symptoms may develop while injecting or immediately after injecting and are reversible. For this reason, the patient should be monitored during and after the injection in order to detect the symptoms of an oil-related pulmonary embolism in good time. Supportive therapy, such as supplemental oxygen therapy, should usually be used. Cases of anaphylactic reactions have been reported after Testosterone Undecanoate injection. This medicine contains castor oil as an excipient, which can cause severe allergic reactions.

How to Dose Testosterone Undecanoate Correctly

Start of treatment. For maintenance therapy, this may be shorter than 10 to 14 weeks and may be as little as 6 weeks, depending on serum testosterone levels and clinical signs. Equilibrated concentrations are rapidly achieved after this shock dose. Individualized treatment adjustment. The recommended dosing schedule of 10 to 14 weeks should be adhered to. During maintenance therapy, serum testosterone levels should be closely monitored. At the end of the interval between injections, it is recommended that serum testosterone levels be measured regularly, taking into account clinical symptoms. SerumTES should be in the lower third of the normal range. If the level is lower than normal, it may be necessary to shorten the interval between injections. If levels are high, consider increasing intervals between injections. Current or previous history of liver cancer. Hypersensitivity to this medicine or any of its ingredients. Hypercalcaemia is associated with malignant tumors. Did you see Testosterone Undecanoate for sale for females? It is false medicaments. Do not use it in women.
