A Testogel pump typically lasts between 30 and 60 days, depending on your prescribed daily dose. Each pump contains 60 metered doses of testosterone gel, with one actuation delivering 20.25 mg of testosterone. If you are prescribed the standard starting dose of two actuations daily, your pump will last approximately 30 days. Lower doses extend this duration, whilst higher doses deplete the pump more quickly. Testogel is a long-term testosterone replacement therapy for confirmed hypogonadism, requiring regular monitoring by your GP or endocrinologist. Understanding how long your pump lasts helps you plan prescription refills and maintain consistent treatment without interruption.

Summary: A Testogel pump lasts 30 to 60 days depending on your prescribed daily dose, with two actuations daily lasting approximately 30 days.

  • Each Testogel pump contains 60 metered doses, with one actuation delivering 20.25 mg of testosterone in 1.25 g of gel.
  • The standard starting dose is two actuations once daily, applied to clean, dry skin on the shoulders and upper arms only.
  • Testogel is a prescription-only medicine and Schedule 4 controlled drug requiring regular monitoring of testosterone levels and haematocrit.
  • Dose adjustments are common during initial treatment, directly affecting how long each pump lasts and prescription refill timing.
  • Allow gel to dry for 3–5 minutes after application, cover with clothing, and avoid swimming or showering for at least 2 hours.
  • Request repeat prescriptions approximately one week before your current pump runs out to avoid treatment interruption.

How Long Does a Testogel Pump Last?

A single Testogel 16.2 mg/g pump canister typically lasts between 30 to 60 days, depending on your prescribed daily dose. Each pump contains 60 metered doses of testosterone gel (after initial priming), with one actuation delivering 1.25 g of gel containing 20.25 mg of testosterone. The duration of your pump therefore depends entirely on how many actuations you are instructed to apply each day.

For patients prescribed the standard starting dose of two actuations daily (equivalent to 40.5 mg testosterone), one pump will last approximately 30 days. If your dose is lower—for instance, one actuation daily—the same pump will last around 60 days. Some patients may require a higher dose of three actuations daily following dose titration, which means their pump will be depleted more quickly, lasting approximately 20 days. The Summary of Product Characteristics (SmPC) specifies a maximum number of actuations per day; do not exceed this limit without medical advice.

It is important to understand that Testogel is a long-term testosterone replacement therapy prescribed for confirmed hypogonadism (low testosterone levels documented on at least two separate morning blood tests, accompanied by clinical symptoms). The pump itself is designed for convenience and accurate dosing, but it does not indicate how long the treatment will continue. Most men with hypogonadism require ongoing therapy, with regular monitoring by their GP or endocrinologist to assess testosterone levels and adjust dosing as needed.

If you are unsure about your prescribed dose or how long your pump should last, check your prescription label or contact your GP or pharmacist for clarification. Never adjust your dose without medical advice, as both under- and over-replacement can lead to unwanted effects.

Understanding Testogel Pump Dosage and Duration

Testogel 16.2 mg/g (testosterone gel) is formulated to deliver a controlled amount of testosterone through the skin, providing steady hormone replacement throughout the day. The pump mechanism ensures consistent, accurate dosing, which is crucial for maintaining stable testosterone levels and minimising fluctuations that can affect mood, energy, and physical wellbeing.

Each actuation of the Testogel pump dispenses 1.25 g of gel containing 20.25 mg of testosterone. According to the SmPC and British National Formulary (BNF), the typical starting dose is two actuations once daily, applied to clean, dry, intact skin on the shoulders and upper arms only. Your clinician will determine your specific dose based on baseline testosterone levels, symptoms, and response to treatment.

Dose adjustments are common during the first few months of therapy. After initiating treatment or adjusting your dose, testosterone levels are usually checked within a few weeks (typically around two weeks, with blood taken at a specified time relative to gel application as per the SmPC). Your dose may be increased or decreased by one actuation at a time, based on these results and your clinical response. The SmPC sets a maximum daily number of actuations; your clinician will not exceed this limit. These adjustments directly impact how long each pump lasts.

The pharmacokinetics of Testogel involve transdermal absorption, with testosterone entering the bloodstream gradually over several hours following application. Steady-state levels are typically achieved within a few days of consistent use. This delivery system aims to provide more stable testosterone levels compared with intramuscular injections, which produce more pronounced peaks and troughs. Regular monitoring includes not only testosterone levels but also safety parameters such as haematocrit (treatment should be stopped or adjusted if haematocrit exceeds 54%), prostate-specific antigen (PSA) and prostate assessment as clinically indicated, and liver function tests where appropriate, in line with UK endocrinology guidance.

Factors That Affect How Long Your Testogel Pump Lasts

Several factors influence how long your Testogel pump will last, with prescribed dosage being the primary determinant. As mentioned, patients on lower doses will use fewer actuations per day, extending the life of each pump. However, other practical considerations can also affect pump duration.

Proper pump technique is essential. For Testogel 16.2 mg/g pump, each actuation should be a full, complete depression of the pump mechanism, with the gel dispensed into the palm of your hand and then applied to the shoulders and upper arms. Partial or incomplete actuations may deliver less gel than intended, potentially leading to under-dosing. If you are uncertain about correct technique, ask your pharmacist to demonstrate during your first prescription collection, and refer to the Patient Information Leaflet supplied with your pump.

Dose titration and changes will alter how long your pump lasts. If your clinician increases your dose following blood test results, you will deplete your pump more quickly and may need to request prescriptions more frequently. Conversely, dose reductions will extend pump duration. It is important to inform your GP surgery of any dose changes so they can adjust your repeat prescription schedule accordingly.

Wastage and spillage can occasionally occur, particularly when learning to use the pump initially. The gel should be dispensed carefully into the palm and applied to the correct sites to minimise loss. If significant wastage occurs regularly, this may shorten how long your pump lasts and could indicate a need for technique review with your pharmacist or practice nurse.

Finally, adherence to daily application affects overall usage patterns. Apply your dose at the same time each day, preferably in the morning, to maintain consistent testosterone levels. Missing doses does not mean your pump will last longer in a therapeutically meaningful way—consistent daily use is essential for maintaining stable testosterone levels. If you frequently forget doses, discuss this with your healthcare provider, as erratic use can lead to symptom recurrence and suboptimal treatment outcomes.

Getting Your Testogel Prescription Refilled in the UK

In the UK, Testogel is a prescription-only medicine (POM) and a Schedule 4 (Part II) controlled drug. It cannot be purchased over the counter. Most patients receive their Testogel through NHS repeat prescriptions managed by their GP surgery, though some may be under the care of hospital endocrinology services who coordinate prescriptions with primary care.

For ongoing treatment, it is advisable to register for a repeat prescription service with your GP surgery. This allows you to request refills regularly without needing a new appointment each time, though periodic reviews (typically every 6–12 months) are necessary to monitor treatment efficacy and safety. Many surgeries now offer online prescription ordering through patient portals, the NHS App, or third-party services, making the process more convenient.

Timing your prescription requests is important to avoid running out of medication. Given that a pump lasts 30–60 days depending on dose, you should request your repeat prescription approximately one week before your current pump is due to run out. Most GP surgeries require 48–72 hours to process repeat prescriptions, and there may be additional time needed for pharmacy dispensing.

If you are approaching the end of your pump and have not yet received your refill, contact your GP surgery or pharmacy promptly. Running out of testosterone replacement therapy can lead to recurrence of hypogonadism symptoms including fatigue, low mood, reduced libido, and loss of wellbeing within days to weeks.

Private prescriptions are also available for those not accessing treatment through the NHS, though costs can be substantial. Prices vary; consult the BNF or your pharmacy for current pricing. Some patients initially assessed privately may be able to transfer their ongoing care and prescriptions to their NHS GP through a process called shared care, which should be discussed with both your private specialist and GP.

Storing and Using Your Testogel Pump Correctly

Proper storage and handling of your Testogel pump is essential for maintaining medication efficacy and ensuring safety for yourself and others in your household. Testogel should be stored at room temperature (below 25°C), away from direct heat and sunlight. Do not refrigerate or freeze the pump, as this may affect the gel formulation and pump mechanism.

Keep the pump out of reach of children and pets. Testosterone can cause serious adverse effects if accidentally transferred to children or women through skin contact. After application, allow the gel to dry completely (typically 3–5 minutes) before dressing, and cover the application site with clothing. Wash your hands thoroughly with soap and water immediately after use. If another person comes into contact with the application site, they should wash the affected area with soap and water promptly.

The application site should be clean, dry, and intact skin on the shoulders and upper arms only (not the abdomen or genital area). Avoid applying to broken skin, cuts, or areas of irritation or dermatitis. Do not apply Testogel immediately after showering or bathing—wait until your skin is completely dry. Similarly, avoid swimming, showering, or vigorous exercise for at least 2 hours after application to ensure adequate absorption, as specified in the SmPC.

Priming the pump is necessary when first using a new canister. Depress the pump mechanism fully three times as instructed in the Patient Information Leaflet, discarding this gel (do not apply to skin), to ensure the pump is properly primed and will deliver accurate doses. Once primed, each subsequent actuation will deliver the correct 1.25 g dose.

Flammability warning: Testogel contains alcohol and is flammable. Avoid fire, flames, and smoking until the gel has dried completely on your skin.

If you experience skin irritation, redness, or allergic reactions at application sites, contact your GP. Rotating application sites within the permitted areas (alternating between shoulders and upper arms) can help minimise local skin reactions. Never share your Testogel pump with others, even if they have similar symptoms, as testosterone replacement requires proper diagnosis and monitoring.

If you experience any side effects, including those not listed in the Patient Information Leaflet, report them via the MHRA Yellow Card scheme at www.mhra.gov.uk/yellowcard or search for 'Yellow Card' in the Google Play or Apple App Store. If you have concerns about your treatment or experience unexpected effects, seek medical advice rather than discontinuing therapy abruptly.

Frequently Asked Questions

How many days will my Testogel pump last if I use two pumps every morning?

If you apply two actuations daily (the standard starting dose), one Testogel pump will last approximately 30 days. Each pump contains 60 metered doses after priming, so using two actuations per day means you will deplete the pump in about one month.

Can I use Testogel on my stomach or just my arms?

You must apply Testogel only to clean, dry, intact skin on your shoulders and upper arms, not on your abdomen or genital area. This application site is specified in the Summary of Product Characteristics to ensure proper absorption and minimise the risk of transfer to others.

What happens if I run out of Testogel before my next prescription?

Running out of testosterone replacement therapy can lead to recurrence of hypogonadism symptoms including fatigue, low mood, reduced libido, and loss of wellbeing within days to weeks. Contact your GP surgery or pharmacy promptly if you are approaching the end of your pump without a refill, and request repeat prescriptions approximately one week before depletion.

How is Testogel different from testosterone injections?

Testogel provides gradual transdermal absorption with more stable daily testosterone levels, whilst intramuscular injections produce more pronounced peaks and troughs over weeks. Both are effective testosterone replacement options, but the gel offers convenience of daily home application and steadier hormone levels, which some patients find improves symptom control.

Do I need a new prescription every time my Testogel pump runs out?

No, most patients use an NHS repeat prescription service through their GP surgery, allowing regular refills without a new appointment each time. However, you will need periodic reviews (typically every 6–12 months) to monitor treatment efficacy, testosterone levels, and safety parameters such as haematocrit and prostate health.

Can my partner or children touch the area where I applied Testogel?

No, avoid skin-to-skin contact with the application site until the gel has dried completely and the area is covered with clothing. Testosterone can transfer to others through direct contact and cause serious adverse effects in children and women, so wash your hands thoroughly after application and ensure others wash any area that accidentally contacts the gel.
