The role of Nebido injections (testosterone undecanoate) in bodybuilding and TRT

Nebido Enanthate Sustanon Comparison

Nebido injection is highly popular in the bodybuilding industry as well as among fitness enthusiasts. Apart from this, it plays a crucial role in testosterone replacement therapy in men suffering from low or lack of natural testosterone  (hypogonadism). So, here’s everything you need to know about Nebido injection (testosterone undecanoate). Also, here you can learn how it works, who are the suitable candidates, who shouldn’t use it, and what are the potential side effects as well. So here we go.

Use of Nebido?

Nebido is used in men for Testosterone replacement therapy for treating low or no production of natural testosterone (hypogonadism). Nebido is injected into a muscle in the user’s body where it gets stored. And then it gradually releases.

Testosterone deficiency is assured by two separate blood testosterone measurements. And this also comes with clinical symptoms including impotence, tiredness, infertility, low sex drive, depressive moods, and bone loss caused by testosterone deficiency.

How Nebido works

Nebido injection comprises the active ingredient testosterone undecanoate, an ester of the male hormone testosterone that naturally occurs in the body. Testosterone is an androgen that is produced by the testicles. This is the main hormone vital for normal growth and maintenance of the male sex organs and male sexual traits (

The natural testosterone production is regulated by another range of hormones named gonadotrophins. These are released from the pituitary gland situated in the brain. During adult life, testosterone is vital for sperm production, in maintaining sex drive, sustaining erectile potency, etc. The other factors are the functioning of the prostate gland along with other reproductive structures.

It also has functions in the skeleton, kidney, skin, muscles, liver, bone marrow, and central nervous system.

Low levels of testosterone can promote decreased impotence, infertility sex drive, because of decreased sperm production. The other reasons are decreased physical and mental activity, fatigue, and weakening of bones (osteoporosis). Testosterone is recommended as replacement therapy when the natural testosterone level in the body is too low, causing problems mentioned above.

Natural testosterone level is likely to fall slowly with the increasing age. And it falls rapidly with the surgical removal of the testicles (testicular cancer). The natural testosterone production may also fall because of the reduced functioning of the testicles (hypogonadism or eunuchoidism) resulted by testicular disease. Or this might be due to decreased gonadotrophin production in the pituitary gland, caused by pituitary disease.

Testosterone replacement therapy allows natural testosterone levels to return to a normal level. This relieves the symptoms of T deficiency.

How Nebido is administered

Nebido injection is considered a depot injection. It is slowly injected into the muscle of the buttock and there it forms a reservoir of that product. The testosterone gradually releases over some time from the reservoir into the bloodstream.

The injection is generally given once in every 10 to 14 weeks. However, the frequency will depend on the specific testosterone levels of an individual. After the first injection, you may have to come back for another injection after six weeks. Therefore, the correct testosterone level is achieved quickly.

You can consult a doctor if you experience signs such as frequent and persistent erections, nervousness, irritability, or weight gain after starting the TRT. These signs suggest that the testosterone levels are too high and the dose needs to be adjusted.

You need to have regular blood tests so you can monitor the red blood cells, the function of the liver, and the prostate-specific antigen (PSA) level. Remember that testosterone can increase the chances of prostate cancers and enlargement of the prostate.

The health expert will perform various examinations to assure the user don’t have prostate cancer before they start TRT with Nebido. The health experts need to perform a digital rectal exam for checking the prostate gland of the users at least once a year while they are receiving TRT.

People with the below problems shouldn’t have Nebido injections. The problems we are talking about are:

  • Breast cancer.
  • Primary liver cancer.
  • Prostate cancer.
  • Kidney disorder called nephrosis or nephrotic syndrome.
  • High level of calcium in their blood (hypercalcaemia).

Nebido injection is not advisable for children, adolescents, and women. This as medicine should not be used if the users are allergic to any of its ingredients. You should inform the health expert if they have previously had such an allergy.

If you experience an allergic reaction by using this problem, you should stop using this medicine and inform the doctor or pharmacist without wasting more time.

Meanwhile, people with below-mentioned factors should use Nebido more carefully:

  • Epilepsy.
  • Diabetes.
  • Elderly people.
  • People with a history of kidney or liver disease.
  • Having heart disease, eg heart attack, or heart failure.
  • History of high blood pressure (hypertension).
  •              Cancer spread from its original site to the bones (skeletal metastases).
  • History of migraines.
  • Sleep apnoea (when breathing temporarily stops during sleep).

Check out the Nebido injection side effects

The potential side effects can badly impact an individual’s health in different ways. Here are some side effects associated with Nebido. These side effects affect people who have been using higher doses for a prolonged time.

  • Headache.
  • Feeling sick and vomiting.
  • Mood changes.

  •                      Reaction at the injection site.
  • Prostate problems, such as the growth of the prostate gland, increased PSA levels, and prostate cancer (see warning section above).

  • Change in sex drive.
  • Breast pain, enlargement of the breasts.

However, here take a look at some of the brilliant advances of undergoing TRT with Nebido.

Here are the bodybuilding benefits of having TRT with Nebido

  1. More muscle, less fat

Testosterone helps in increasing lean muscle mass. And this is great for controlling weight and increasing energy. For men suffering from testosterone deficiency, TRT can help in decreasing fat mass and increasing muscle size as well as strength. However, to mug up the benefits to the fullest, users should combine TRT with exercise and strength training (

TRT therapy helps in increasing the muscle mass by boosting the protein synthesis procedure. It consequently fuels the nitrogen retention procedure in the muscle tissues. Thus, testosterone replacement therapy is equally popular among fitness enthusiasts as well as among people suffering from muscle wasting diseases.

  1. Healthy cardiovascular health

A healthy heart helps in pumping the blood to the remaining parts of the body. It provides muscles and organs with the required oxygen so they can give their peak performance while doing rigid exercise. Testosterone promotes red blood cell production through the bone marrow. Low testosterone levels are associated with various cardiovascular diseases.

However, can TRT help fight heart diseases? According to the small studies, men with heart disease who went for testosterone therapy had heart improvements. Even some were able to boost their walking distance by 33%.

Another study found out that TRT widened healthy arteries. However, a more recent study of 83,000 men discovered that men who got their natural T level back were 24% less likely to experience a heart attack and 36% less likely to have a stroke.

  1. Strengthens bones

Testosterone plays a crucial role in bone mineral density. Bone density reduces as men age and testosterone reduces. This increases the risk of weak bones and osteoporosis. Strong bones support your muscles and internal organs, which can boost athletic performance.

Research shows that bone density increases with TRT with proper treatment. TRT considerably increases the spinal and hip bone density that is a great support while doing an athletic performance. Another study on females transitioning into males showed that testosterone enhances bone mineral density.

  1. Better verbal memory

The research reported that men with higher testosterone have a reduced occurrence of Alzheimer’s disease. Also, there is evidence for a strong connection between testosterone and cognitive abilities including verbal memory and faster processing.

  1. Increased libido and arrogance

Testosterone levels naturally increase the sexual arousal, activity as well as arrogance that help in doing heavy exercises. Men with higher testosterone levels usually enjoy more sexual activity. Older men require more testosterone for libido and for treating erectile dysfunction.

Studies found that testosterone therapy can advance your sexual performance and health. It also reported that there is a maximum testosterone level before there’s no enhanced response. For men without hypogonadism, increasing the testosterone may not help in boosting the libido.

  1. Enhanced mood

Reduced testosterone levels are often led by the poorer quality of life. Some symptoms of testosterone deficiency include depression, irritability, and fatigue. However, research shows that this may only be for men suffering from hypogonadism. Men with a normal testosterone decrease over time didn’t show increased depression.

The effects of TRT on mood can differ from person to person. Men with hypogonadism reported better mood and well-being, along with reduced irritability and fatigue. Research shows that TRT may also be an effective anti-depressant aid.

It is recommended to observe the limitations of using intramuscular injections in patients with acquired or inherited blood clotting irregularities. Testosterone and derivatives can increase coumarin-derived oral anticoagulant activities.

One with thrombophilia should use Nebido with caution. It is because there have been post-marketing studies and reports of thrombotic events in these patients at the time of testosterone therapy. Nebido should be taken cautiously by patients suffering from epilepsy and migraine, since the conditions may aggravate.
