Testosterone Replacement (TRT)

Offered at our convenient location in London

Testosterone Replacement (TRT)

Testosterone replacement is the use of testosterone and hormone balancing to reverse the effects of ageing and revitalise both men and women.

Refresh Your Mind and Body

Testosterone Replacement (TRT)

Ageing can create undesirable effects, not just regarding how we look but also how we feel. A lack of energy, loss of libido, weight gain, fatigue, and even more serious issues such as depression and anxiety may arise. Even if you eat nutritiously and exercise regularly, you may experience these effects. In some people, hormone imbalance causes these unwanted effects. 

If you experience any of these undesirable symptoms, Dr. Grant Hamlet can help you refresh your mind and body. Dr Grant Hamlet specialises in anti-ageing and revitalisation treatments, including replacement treatments to rebalance hormone levels that are out of alignment. If you’re ready to discover how testosterone replacement can benefit you, then call Dr Hamlet at 0207 127 4377 or book a consultation online.

About Testosterone and Hormone Therapy

Testosterone Replacement (TRT)

Testosterone is one of the most important sex hormones (androgens) produced in the body. It is the primary hormone involved with many of the most prominent masculine attributes and is essential for a variety of healthy bodily functions. Throughout adult life, testosterone helps maintain sex drive, the production of sperm cells, male hair patterns, muscle mass, and bone mass. In women, testosterone also plays an important role. Testosterone affects women’s energy, libido, and mood. For more information on women, visit our dedicated page for female hormone therapy.

Testosterone usually declines with age. Hormone levels generally reach their peak at age 20 and decline from that point on. When you are in your thirties and forties, your testosterone level will start to decline at 1 percent a year. This is normal. However, low testosterone in some men may be due to hypogonadism. Hypogonadism is when the body cannot produce the normal amount of testosterone for the age and health of the individual. This is caused by a problem with the testicles or pituitary gland (the pituitary gland controls the testicles). Testosterone replacement offers a meaningful solution for men who have to live with this disease.

Candidates for Testosterone Replacement

Signs of low testosterone in men may include decreased sex drive, erectile dysfunction (ED), lowered sperm count, or increased breast size. Men may also experience symptoms similar to those seen during menopause in women – hot flashes, increased irritability, inability to concentrate, and depression. Andropause is when a man’s hormonal levels change with age. It differs from menopause because it’s a more gradual decline in hormone production rather than an abrupt switch. This gradual decline makes it tougher for men to recognise. Symptoms often creep up slowly. 

Testosterone Replacement (TRT)

Some men may experience loss of body hair and reduced muscle mass, their bones may be more brittle and prone to fracture, and their testes may become smaller and softer. Younger men may also be susceptible to hormone imbalances. In younger men, their voices may fail to deepen. With low testosterone, women can experience a decrease in sex drive, lack of energy, decreased “enjoyment of life”, and even depression.

  • Depression
  • Restless sleep
  • Difficulty focusing
  • Low self-confidence


  • Early osteoporosis or other signs that your muscle and bone mass are declining
  • Weight gain
  • Gynecomastia (hormone imbalance contributes to swollen breast tissue)

Diagnosis and Consultation with Dr Hamlet

We want you to live your best life! If you identify with the above-listed symptoms, you may have low testosterone or a hormonal imbalance. A detailed analysis of your medical history and a physical examination, coupled with thorough laboratory analysis is necessary to determine what treatments may be best suited for your condition. It’s also important to discuss how you are feeling. Some patients may be “in a normal range” yet still experience symptoms. This is because optimal hormonal balance can differ for each individual.

We first recommend meeting with your primary doctor. If you have already done this, then it’s time to reach out to Dr Hamlet.

Some studies have estimated that up to 25% of men seeking testosterone therapy never had their hormonal levels checked.[2] This is a mistake. It’s important to have your hormone levels measured and assessed by a specialist like Dr Hamlet. Give our office a call at 0207 127 4377 or schedule a consultation online to learn more about improving testosterone levels. During your consultation with Dr Hamlet, he will explain treatment to you and set up a plan to balance your hormone levels

You can improve your sexual life, enhance mental clarity, and feel more refreshed and invigorated to do the things you love. To learn more, take a peek at our blog.

TRT Treatment

Testosterone Replacement (TRT)

Dr Hamlet, or one of his experienced nurses, administer testosterone therapy via intramuscular injection once a week for men and once a month for women. We usually perform follow-up blood tests once every six months after a patient completes the initial phase, or sooner if the specific case suggests they might be necessary. Treatments will be adjusted to your current hormone levels so that you receive just the amount you need to live a healthy, active life.


You will notice improvements in your daily life within a few weeks. Many patients see improvements in their energy levels and sex life after three to six weeks. The longer you undergo TRT, the better your results will be. Your hormones will adjust and you will be able to live a healthier, more satisfying life.

Alongside the results you experience with TRT, we recommend a healthy lifestyle to further enjoy your TRT outcome. Maintaining a healthy weight, exercising regularly, sleeping for about eight hours a night, and eating nutritiously will allow you to improve upon your boost from TRT.

How Much Does TRT Cost in London?

The cost of your testosterone therapy treatment is based on the plan designed by you and Dr Hamlet. We will provide a cost breakdown to set you up for a healthy, positive future. If you are interested in TRT, give our office a call at 0207 127 4377 and schedule a consultation with Dr Hamlet. He will assess your health and develop a personalised treatment plan that will help you regain control of your life.


Are there any side effects of testosterone replacement?

Dr Hamlet will go over side effects associated with testosterone therapy during your consultation. Side effects are unlikely, but some reactions might include acne, increased breast size, and lower sperm count. Testosterone replacement will only be suggested if you qualify as healthy candidate. The presence of underlying conditions may require you to seek alternative treatments. Patients who have prostate or breast cancer should not pursue TRT. If you had one of these cancers in the past and have been successfully treated, you may be able to undergo TRT.

Does testosterone replacement therapy really work?

Yes! Testosterone boosters are proven to help balance hormones and restore energy for many patients. It is important to find a qualified doctor who understands how to balance the appropriate amount of testosterone for your health. Dr Hamlet remains dedicated to improving the lives of his patients. He takes the time to learn about your health and determine if TRT is the best solution for you.

How long does it take to feel the effects of testosterone injections?

The length of time it takes to feel the effects of TRT will depend on your hormone levels when you start treatment as well as your lifestyle choices. Dr Hamlet will inform you of the projected timeline when you begin treatment. This will be unique for each person. Most patients begin to notice improvement after three to six weeks. The longer you undergo treatment and remain consistent, the better your results. It will take a few months for your hormones to balance out. When they do find equilibrium, you will be able to sleep better, think clearly, have the energy to get on about your day, and enjoy a healthy sex life. Schedule a consultation with Dr Hamlet today to learn more about TRT and if it is a good solution for your concerns.

What is the average testosterone level by age?

Men range from 270 to 1070 ng/dL and have an average of 679 ng/dL. Testosterone levels typically peak at age 20 and naturally begin to decline from that point on. However, hormone replacement is about more than just being “in the normal range”. The most efficacious hormone therapy achieves your optimal level where you feel and perform the best.
