Testosterone Enantate is a manufactured version of the naturally occurring male sex hormone, testosterone.
It is used in adult men for testosterone replacement to treat various health problems caused by a lack of testosterone (male hypogonadism). This should be confirmed by two separate blood testosterone measurements and also include clinical symptoms such as:
• Impotence
• Infertility
• Low sex drive
• Tiredness
• Depressive moods
• Bone loss caused by low hormone levels.


Do not use Testosterone Enantate:

• if you are allergic to Testosterone Enantate or any of the other ingredients of this medicine
• if you suffer from androgen (steroid hormone) dependent prostate cancer or breast cancer
• if you have high calcium levels in your blood
• if you have or have had tumours of the liver •if you have kidney disease (nephrosis) Warnings and precautions

Talk to your doctor before using Testosterone Enantate if you:

• have liver problems including severe upper abdominal complaints
• have a tendency to retain fluid causing, for example, swelling of the ankles
• suffer from sleep apnoea (interrupted breathing during sleep), as this may get worse
• are suffering from severe heart, liver or kidney disease; treatment with Testosterone Enantate may cause severe complications in the form of water retention in your body sometimes accompanied by (congestive) heart failure
• have high blood pressure or if you are being treated for high blood pressure as testosterone may cause a rise in blood pressure
• have or have ever had blood clotting problems; thrombophilia (an abnormality of blood coagulation that increases the risk of thrombosis – blood clots in blood vessels)
• have epilepsy, migraine, diabetes mellitus or cancerous bone disease.
Testosterone Enantate should not be used in women because they may develop signs of virilisation, e.g. acne, increased hair growth on the face or body and voice changes.
Male hormones such as Testosterone Enantate are not suitable for increasing muscular development in healthy people or for increasing physical ability.

 Medical examination/consultation

Male hormones may increase the growth of prostate cancer and enlarged prostate glands (benign prostatic hypertrophy). Before your doctor injects Testosterone Enantate, s/he will examine you to check that you do not have prostate cancer. If you are older, you may be at an increased risk for the development of prostate enlargement when using Testosterone Enantate. Although there is no clear evidence that sex hormones such as Testosterone Enantate actually generate cancer of the prostate, they can enhance the growth of any existing cancer of the prostate.
As a precaution, regular examinations of the prostate are recommended in men, especially if you are elderly.
If you are on long-term androgen therapy blood tests should be carried out periodically
The following blood checks should be carried out by your doctor before and during the treatment:
• testosterone blood level and
• full blood count
Following the use of hormonal substances such as androgen compounds, cases of benign (non-cancerous) and malignant (cancerous) liver tumours have been observed to occur. Although it is improbable that a tumour will occur, these would present a health concern. In isolated cases, internal bleeding could occur from these tumours, which might endanger life. Thus you should always seek the immediate emergency attention of a doctor when you suffer severe abdominal pains. Not all unusual sensations you might feel in your upper abdomen can be counted as a possible sign of tumour or bleeding. Those that do not disappear within a short time should however better be brought to your doctor’s attention.

Additional information on special populations Children and adolescents
Testosterone Enantate is not indicated for use in  children and adolescents.
In children and adolescents, earlier development of male secondary sex characteristics (masculinisation) may occur. Testosterone can affect bone growth and in some cases reduce final height.
Safety and efficacy have not been adequately determined in children and adolescents.

Elderly patients (65 years or older)
Limited data do not suggest the need for a dosage adjustment in elderly patients.

Patients with impaired liver function
No formal studies have been performed in patients with liver impairment. The use of Testosterone Enantate is contraindicated in men with past or present liver tumours (see “Do not use Testosterone Enantate”). Patients with impaired kidney function No formal studies have been performed in patients with kidney impairment.
