Is Testogel a Controlled Drug in the UK?
Yes, Testogel is a controlled drug under UK law. Testosterone, the active ingredient in Testogel, is classified as a Class C controlled substance under the Misuse of Drugs Act 1971 and a Schedule 4 Part II controlled drug (anabolic steroid) under the Misuse of Drugs Regulations 2001. This classification applies to all testosterone products, regardless of their intended use.
However, Testogel is also a prescription-only medicine (POM), which means it can only be legally obtained with a valid prescription from a registered healthcare professional. Testosterone replacement therapy products, including Testogel, are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA) to ensure patient safety and appropriate clinical use.
The distinction between Schedule 4 Part II controlled drugs and higher schedule substances (such as Schedule 2 opioids) is important. Testogel prescriptions do not require special controlled drug wording and can be issued electronically or in standard written format. However, prescriptions are valid for 28 days from the date stated (or the date of issue if no date is specified). Possession of Testogel is lawful if you have been legitimately prescribed the medication for a recognised medical condition, such as hypogonadism.
Important legal points:
-
It is illegal to supply Testogel to another person, even if they report similar symptoms
-
Importing or exporting testosterone products by post or courier without appropriate authority is unlawful
-
Personal possession when travelling may require documentation (prescription or letter from your doctor)
-
Misuse of testosterone products outside of legitimate medical treatment, particularly for bodybuilding or athletic performance, carries significant health risks and may have legal implications
Always ensure you obtain and use Testogel only as directed by your prescribing clinician and in accordance with UK law.
Legal Classification of Testogel Under UK Law
Under UK medicines legislation, Testogel is classified as both a controlled drug and a prescription-only medicine (POM). It is regulated under the Human Medicines Regulations 2012 and the Misuse of Drugs Regulations 2001. This dual classification requires that the product can only be sold or supplied by a registered pharmacy in accordance with a prescription issued by an appropriate practitioner, such as a general practitioner, consultant endocrinologist, or urologist.
The active ingredient in Testogel is testosterone, a naturally occurring hormone that is synthetically manufactured for therapeutic use. Testosterone is classified as a Class C controlled drug under the Misuse of Drugs Act 1971 and a Schedule 4 Part II controlled drug (anabolic steroid) under the Misuse of Drugs Regulations 2001. When prescribed for medical conditions such as male hypogonadism (testosterone deficiency), testosterone products are legal and considered essential treatments. The MHRA oversees the licensing and safety monitoring of all testosterone replacement therapies available in the UK, ensuring they meet rigorous standards for quality, efficacy, and safety.
Key legal points regarding Testogel include:
-
It cannot be purchased over the counter or online without a valid prescription
-
Prescriptions are valid for 28 days from the date stated on the prescription
-
Electronic prescribing (EPS) is permitted; no special controlled drug wording is required
-
Supplying Testogel to another person without appropriate authorisation is illegal
-
Importing or exporting testosterone products by post or courier without a Home Office licence is unlawful
-
Pharmacies must verify prescriptions before dispensing the medication
Legitimate medical use of prescribed Testogel is entirely legal when obtained and used in accordance with your prescription. Healthcare professionals prescribing testosterone products must follow clinical guidelines, including those issued by NICE, the British Society for Sexual Medicine, and the Society for Endocrinology, to ensure appropriate patient selection and monitoring.
Prescription Requirements and Regulations for Testogel
Obtaining Testogel legally in the UK requires a valid prescription from a registered medical practitioner. As a Schedule 4 Part II controlled drug, Testogel prescriptions can be issued using standard NHS or private prescription forms, and electronic prescribing is permitted. Prescriptions are valid for 28 days from the date stated (or the date of issue if no date is specified).
Before prescribing Testogel, clinicians must:
-
Confirm biochemical testosterone deficiency through blood tests (typically two morning samples showing low testosterone levels)
-
Identify symptoms consistent with hypogonadism, such as reduced libido, erectile dysfunction, fatigue, or mood changes
-
Exclude contraindications, including prostate cancer and male breast cancer
-
Assess cautions, such as cardiac, hepatic, or renal impairment, sleep apnoea, and risk factors for prostate disease
-
Discuss potential risks and benefits with the patient, including effects on fertility
-
Establish a monitoring plan for ongoing treatment
Testogel is available in the UK as Testogel 16.2 mg/g gel in a pump dispenser (each actuation of 1.25 g delivers 20.25 mg of testosterone) and as Testogel 50 mg/5 g sachets (1% gel). Prescriptions typically specify the strength, formulation, and quantity to be dispensed. Initial prescriptions are often limited to shorter durations (such as one or two months) to allow for early review and dose adjustment based on clinical response and follow-up testosterone levels.
Once treatment is established, regular monitoring is mandatory and includes:
-
Testosterone blood levels: checked at 2–3 months after initiation or dose change, then every 6–12 months
-
Full blood count (FBC) and haematocrit: at baseline, 3–6 months, then annually. If haematocrit rises to ≥0.54, treatment should be reduced or stopped and the patient investigated
-
Prostate-specific antigen (PSA) and digital rectal examination (DRE): at baseline in men over 40 years or those at increased risk. Refer urgently (per NICE NG12) if PSA is above age-specific reference range, rises by more than 1.4 ng/mL per year, DRE is abnormal, or urinary symptoms are concerning
-
Assessment of symptoms and treatment response
-
Evaluation for adverse effects, including cardiovascular symptoms, mood changes, and sleep disturbance
Pharmacists dispensing Testogel have a professional responsibility to ensure prescriptions are valid and appropriate. They may counsel patients on correct application technique, potential side effects, and the importance of preventing transfer to others, particularly women and children. Repeat prescriptions are typically managed through GP surgeries, with periodic reviews to confirm ongoing clinical need.
Why Testosterone Gel Is Prescription-Only
Testogel is classified as prescription-only due to significant safety considerations and the need for appropriate medical supervision. Testosterone replacement therapy, whilst highly effective for men with genuine testosterone deficiency, carries potential risks that require careful patient selection, monitoring, and dose adjustment.
Key safety concerns include:
Cardiovascular risks: The MHRA has reviewed the evidence on testosterone therapy and cardiovascular events. Whilst there is no consistent evidence of an increased risk, the MHRA advises caution in men with pre-existing cardiovascular disease and recommends monitoring for signs of heart failure or other cardiovascular complications. Medical supervision allows for appropriate risk assessment and monitoring.
Prostate health: Testosterone can stimulate prostate tissue growth. Although there is no definitive evidence that testosterone therapy causes prostate cancer, it is contraindicated in men with prostate or male breast cancer. Regular PSA monitoring and digital rectal examination help detect potential prostate abnormalities early. Patients should be referred urgently if PSA is elevated, rises significantly, or if urinary symptoms or DRE findings are concerning.
Polycythaemia: Testosterone therapy stimulates red blood cell production, which can lead to polycythaemia (elevated haematocrit). This condition increases blood viscosity and may raise the risk of thrombotic events. Regular blood count monitoring is essential; if haematocrit reaches ≥0.54, treatment should be reduced or stopped and the patient investigated.
Transfer to others: Testogel is applied topically and can be inadvertently transferred to partners or children through skin-to-skin contact. This poses particular risks for women (potential virilisation effects) and children (premature sexual development). To prevent transfer: wash your hands thoroughly after application, allow the gel to dry before dressing, cover the application site with clothing, and wash the application area before close skin contact. Proper application technique and precautions require professional guidance.
Other important cautions: Testosterone therapy may worsen obstructive sleep apnoea and suppresses spermatogenesis, which may affect fertility. Application-site reactions can occur.
Misuse potential: Testosterone products are sometimes misused for bodybuilding or athletic performance enhancement. Prescription-only status helps prevent inappropriate use and ensures the medication reaches those with genuine medical need. Supraphysiological doses carry serious health risks, including cardiovascular complications, psychiatric effects, and (with certain oral anabolic steroids) liver damage.
Safe and Legal Ways to Obtain Testogel in the UK
The only safe and legal method to obtain Testogel in the UK is through a valid prescription from a registered healthcare professional following appropriate clinical assessment. There are several legitimate pathways to access testosterone replacement therapy.
NHS Route: Patients experiencing symptoms suggestive of testosterone deficiency should consult their GP as the first step. Your doctor will take a detailed medical history, perform a physical examination, and arrange blood tests to measure testosterone levels. If hypogonadism is confirmed and treatment is appropriate, your GP may initiate therapy or refer you to an endocrinologist, urologist, or specialist in andrology for further assessment and management. NHS prescriptions for Testogel are dispensed at standard prescription charges (or free for eligible patients).
Private Healthcare: Patients may choose to consult private endocrinologists, urologists, or men's health specialists. Private consultations typically involve the same rigorous diagnostic process, including blood tests and clinical assessment. Private prescriptions can be dispensed at any pharmacy, though patients pay the full cost of the medication. Ensure any private clinic is registered with the Care Quality Commission (CQC) and employs GMC-registered doctors.
Important safety advice:
-
Never purchase Testogel from unregulated online sources or websites that do not require a prescription. These products may be counterfeit, contaminated, or incorrectly dosed.
-
Avoid obtaining testosterone products from gyms, bodybuilding forums, or non-medical sources.
-
Do not share prescribed Testogel with others, even if they report similar symptoms. Supplying a controlled drug to another person is illegal.
-
Remember that testosterone is a Schedule 4 Part II controlled drug. Importing or exporting it by post or courier without appropriate authority is unlawful.
-
If you have concerns about the cost of treatment, discuss this with your GP, as NHS provision may be appropriate.
When to seek urgent medical advice:
-
Call 999 or 112 if you experience severe chest pain, acute breathlessness, or signs of a stroke whilst using Testogel.
-
Contact NHS 111 for urgent advice if you develop significant ankle swelling, persistent mood changes, or concerning urinary symptoms.
-
Contact your GP or prescribing clinician promptly if you notice other potential adverse effects.
Regular follow-up appointments are essential to ensure safe, effective treatment and to monitor for potential complications.
Reporting side effects: If you experience a side effect, you can report it via the MHRA Yellow Card Scheme at yellowcard.mhra.gov.uk or by searching for 'MHRA Yellow Card' in the Google Play or Apple App Store. Reporting helps improve the safety of medicines for everyone.
Frequently Asked Questions
Can I buy Testogel without a prescription in the UK?
No, you cannot legally buy Testogel without a prescription in the UK. Testogel is a prescription-only medicine and a Schedule 4 Part II controlled drug, meaning it can only be obtained through a valid prescription from a registered healthcare professional such as a GP or specialist.
What happens if I'm caught with Testogel without a prescription?
Possession of Testogel without a legitimate prescription is unlawful under the Misuse of Drugs Act 1971. Whilst personal possession for medical use is legal with a valid prescription, possessing testosterone products without authorisation may result in legal consequences, particularly if there is evidence of supply to others or misuse for non-medical purposes.
How do I get a prescription for Testogel through the NHS?
Start by consulting your GP if you have symptoms of testosterone deficiency such as reduced libido, fatigue, or erectile dysfunction. Your doctor will arrange blood tests to measure testosterone levels (typically two morning samples) and, if hypogonadism is confirmed, may initiate treatment or refer you to an endocrinologist or urologist for specialist assessment.
Is Testogel the same as other testosterone treatments?
Testogel is a transdermal testosterone gel, one of several testosterone replacement therapy options available in the UK. Other formulations include testosterone injections (such as Sustanon or Nebido), patches, and oral capsules (Restandol), each with different administration methods, dosing schedules, and side effect profiles that your clinician will discuss with you.
Can I travel abroad with my Testogel prescription?
Yes, you can travel with prescribed Testogel, but you should carry documentation such as your prescription or a letter from your doctor confirming your medical need. Some countries have stricter controls on testosterone products, so check the regulations of your destination country and consider contacting their embassy before travelling to avoid customs issues.
Why is Testogel controlled if it's used for medical treatment?
Testogel is controlled because testosterone has potential for misuse, particularly in bodybuilding and athletic performance enhancement, and carries significant health risks including cardiovascular complications, polycythaemia, and prostate effects. Controlled drug status ensures appropriate medical supervision, prevents diversion to non-medical use, and protects public health whilst allowing legitimate therapeutic access for patients with genuine testosterone deficiency.
