Product information

Testim is a gel made by Ferring. It is used in the treatment of low testosterone in men, also known as male hypogonadism. It contains testosterone, and works as a replacement therapy. The gel is applied to the shoulders and upper arms, once daily. You can only get Testim in the UK on prescription. Before it can be issued, a doctor will need to ensure you have low testosterone levels with a blood test.

Currently, this item is out of stock, and therefore not available from our site. However, we do offer other treatments for low testosterone through our pharmacy service.  

What is low testosterone?

Testosterone is an androgen (or male sex hormone) produced by the testicles in men (and by the ovaries in women). In men it is integral to several functions, including hair growth, the production of sperm, healthy libido, and the development and maintenance of muscle and bone.

Testosterone production accelerates during puberty, and levels tend to peak during young adulthood. They then usually decline slowly as a man gets older.

Some men may have low testosterone levels from a young age, due to an underlying medical condition (such as an illness affecting the pituitary gland or the testicles, or diabetes). This is called male hypogonadism, and lead to the testicles not developing normally, or reduced muscle and bone mass.

When a man develops low testosterone levels later in life, this is called late onset male hypogonadism. There are several possible causes, such as sustaining an injury or damage to the testicles, obesity, diabetes, or inflammatory conditions affecting the glands.

This can cause symptoms such as loss of sex drive, erectile dysfunction, lethargy and hair loss. However, these symptoms can also occur due to a range of other illnesses; so someone who notices them may not necessarily have low testosterone.

When to speak to a doctor

If you have any of the symptoms listed above, then you should talk to your GP. They will advise that you have your testosterone levels checked with a blood test if they think low testosterone could be the cause, but will also be able to rule out other conditions that might be responsible.

Some men with low testosterone may not get any symptoms, and in such cases, treatment may not be needed. However, someone who has confirmed low testosterone levels which are causing problems may be advised to use replacement therapy.

How does Testim work?

Testim contains a synthetic version of testosterone. When the gel is absorbed into the skin, the active ingredient supplements levels of the hormone, helping to reduce symptoms.

Patients who use testosterone replacement therapy will need to have their levels checked with a blood test regularly. The dose used might be adjusted by a doctor where required.

How can I buy Testim online?

It is not possible to order Testim from our UK pharmacy at the moment, because the treatment is out of stock. However, other similar treatments are available.

Before you start testosterone replacement therapy, you’ll need to speak to a doctor to make sure it is safe for you, and have a blood test to check your testosterone levels. You can arrange a test with your GP, or alternatively, order a testosterone test kit online from us.

You should always use this medication according to the directions given by your prescriber. Make sure you read the information leaflet provided before use.

  1. Prior to being issued this treatment, you will need to have your testosterone levels checked through a blood test. If you don’t have test-confirmed low testosterone levels, and a doctor has not recommended that you use testosterone replacement therapy, then you should not use this medication.
  2. Testim is supplied in single dose tubes. The typical starting dose is one tube daily.
  3. In some cases, this may be increased to two tubes per day.
  4. The gel is applied to the skin on the shoulders or upper arms.
  5. You should never administer it anywhere else, and particularly not to the testes or the genitals.
  6. Do not use the gel on broken or damaged skin.
  7. It is important to administer the gel at the same time every day. Ideally, this should be in the morning, after you’ve taken a bath or a shower.
  8. Ensure the application site is clean and dry before putting on the gel.
  9. Unscrew the lid and break the seal on the end of the tube.
  10. Working from the bottom of the tube, squeeze all of the gel out into your hand.
  11. Spread it in a thin layer on the shoulders or upper arms, using a circular motion. Continue doing this until there is no gel left on the surface of skin.
  12. If you’re applying two tubes, it’s better to use one on one shoulder or upper arm region, and another tube on the other shoulder or upper arm region.
  13. Thoroughly wash your hands following use.
  14. Leave it a few minutes before getting dressed, so that you do not wipe the gel off.
  15. The gel needs time to fully soak in, so you should not shower or bathe for 6 hours after applying it.
  16. You should take precautions to ensure that the gel does not transfer to anyone else. This includes covering the application site with clothing, cleaning your hands thoroughly after use, and not engaging in close skin-to-skin contact or sexual intercourse until a few hours after the gel has dried.
  17. If you forget to apply the gel at the normal time, you should not apply twice the amount next time to make up for the missed dose. If you remember within 12 hours of your missed dose, you can apply it when you remember, then apply the next one as normal. If you remember when your next dose is due in less than 12 hours, leave the one you have missed and simply apply the next dose at the usual time.
  18. You will need to have your testosterone levels monitored on a regular basis during treatment with Testim, with a blood test.

The above only forms a summary of the instructions you will need to follow. More detailed directions are available in the leaflet supplied.

If you are not sure of anything, ask your doctor or pharmacist for advice.
