Testosterone replacement therapy for male hypogonadism when testosterone deficiency has been confirmed by clinical features and biochemical tests (see section 4.4). Each ampoule / vial with 4 ml solution for injection contains 1000 mg testosterone undecanoate corresponding to 631.5 mg testosterone. Each ml solution for injection contains 250 mg testosterone undecanoate corresponding to 157.9 mg testosterone. Generally, injections are spaced weeks apart. NEBIDO is administered by a healthcare professional through a single intramuscular injection, typically in the buttock muscle. This unique delivery system allows for a sustained release of testosterone, minimizing the need for frequent injections. The testosterone undecanoate slowly breaks down and releases testosterone into the bloodstream through a process called lymphatic absorption. Low testosterone levels can significantly impact a man’s quality of life. TRT with NEBIDO can help alleviate these symptoms and improve overall health, but it’s crucial to understand the potential benefits and risks before starting treatment. Nebido works by replacing the body's natural testosterone, which is produced in the testes. In addition to its medical use, testosterone undecanoate is used to improve physique and performance. However, it has advantages over other testosterone esters in that it can be taken by mouth and in that it has a far longer duration when given by injection. Along with testosterone enanthate, testosterone cypionate, and testosterone propionate, testosterone undecanoate is one of the most widely used testosterone esters. Testosterone undecanoate is a testosterone ester and a prodrug of testosterone in the body. The delivery method makes Nebido injections an effective way to raise testosterone in the body. Misusing testosterone undecanoate for bodybuilding purposes, in doses higher than those recommended for medical use, can lead to potential side effects. They generally take its higher doses (despite having normal blood testosterone levels) to boost their performance. If you are experiencing any combination of these symptoms, you may have low testosterone and need testosterone replacement therapy (TRT). 1 brown glass ampoule / brown glass vial with 4 ml solution for injection Ask your pharmacist how to throw away medicines you no longer use.
