Tostran is a form of testosterone replacement therapy. It is a gel, marketed by Kyowa Kirin. The gel is provided in a canister, and dispensed through a pump. This is applied once daily to the skin on the abdomen or on the inside of the thighs on alternating days. Tostran, which is available to buy on prescription from our pharmacy, is used to treat men with testosterone deficiency.
What is testosterone?
Testosterone is a male sex hormone, produced by the testicles in men, and by the ovaries in women. In men, testosterone contributes towards several sexual functions, such as the production of sperm, and libido. It is also important for the maintenance of healthy bones and muscles.
For the majority of men, testosterone levels will peak during young adulthood and gradually decline with age.
When someone is testosterone deficient, this is known as male hypogonadism. Some men may have low testosterone levels from a young age. This can result in delayed puberty, slower development of the testicles and body hair, and reduced bone and muscle mass.
It’s also possible, albeit rare, for men to develop low testosterone during adulthood. This is called late onset hypogonadism. There are several factors that can contribute towards a drop in testosterone, such as diabetes, obesity, and liver or kidney disease. Sometimes, however, the exact cause may not be clear.
Symptoms of low testosterone include loss of sex drive, problems with erections, changes in mood, and loss of bone density. In some cases, a man with low testosterone may not display any noticeable symptoms at all.
When to seek advice
It’s advisable to see a doctor if you develop any of the symptoms listed above. Low testosterone may not be the cause, but they will be able to perform any observations they think necessary, and recommend a testosterone test if they think low levels of the hormone could be responsible.
Testing is done by taking a blood sample. You can get tested at your GP surgery, or alternatively, order a test kit online through our site. Men who have confirmed low testosterone levels may not need treatment if they don’t have any symptoms. However, if low testosterone is suspected to be causing the problems described above, then replacement therapy may be recommended.
How does Tostran work?
Tostran contains a manmade version of testosterone, and therefore works by supplementing levels of the hormone in a man who has testosterone deficiency.
The treatment is a gel, which is applied to the insides of the thighs and the abdomen. The active ingredient is taken up through the skin, and helps to ensure testosterone levels stay at an adequate level. It’s likely that someone using Tostran will need to have their testosterone levels checked on a regular basis, to ensure it is working.
How can I buy Tostran online?
Men with confirmed low levels of testosterone can order Tostran using our consultation and prescription service. Proceed to our medical questionnaire to begin your order, and once complete, one of our GMC-registered doctors will review your case. Following approval, your treatment will be dispensed at our UK pharmacy and shipped by tracked parcel.
Always follow the directions given by your prescriber, and make sure you read the patient information leaflet fully prior to use.
- The typical initiation dose is 3g of gel (equivalent to 60mg of testosterone) daily.
- This may be increased depending on your response. The maximum dose is 4g (80mg).
- The pump needs to be primed prior to first use. You can do this by holding the canister upright and depressing it eight times. No gel will be produced during the first few depressions. Any gel produced during priming should be discarded.
- Once primed, the pump issues a dose of 0.5g (10mg) per depression. So if your dose is 60mg, you’ll need to pump the canister six times to get the dose you need.
- You won’t need to prime the pump for subsequent uses (just the first one).
- The doctor prescribing the gel will tell you how many depressions to use.
- Administer the gel onto clean, unbroken dry skin.
- The gel should be applied once daily. Always try to do it at the same time.
- It can be rubbed onto the abdomen, or split into equal parts and rubbed onto the inside of both thighs.
- The leaflet recommends using both areas on alternating days (abdomen on the first day, both thighs on the second day, abdomen on the third day and so on).
- It must not be used anywhere else on the body or on the genitals.
- Use one finger to rub the gel in until dry.
- Wear loose clothing following application.
- Wash your hands after use.
- Wait until at least two hours after application to have a bath or a shower.
- You will need to have your testosterone levels monitored with blood tests during treatment.
- Do not exceed the prescribed dose.
- If you miss a dose, do not double up on your next dose to make up for it. Skip the one you have missed and apply the next one as scheduled.
