What Is HGH Therapy?

Human growth hormone (HGH, hGH or GH) serves an essential role in adult life, improving lean muscle mass, bone density, physical strength and aerobic capacity while simultaneously promoting fat loss by reducing visceral fat accumulation. It’s perfectly normal as we age for HGH production to slow down, but some men may experience HGH deficiency that negatively impacts their lives. Growth hormone replacement can help men combat these adverse effects and serve as an anti-ageing therapy.

As the name suggests, the human growth hormone is an important mediator of the human growth process. HGH is a small protein made naturally within the body, created by the pituitary gland and then secreted into the bloodstream. 

Growth hormone is something we release a lot of during childhood and teenage years (when we’re growing the most), but as we reach adulthood, the production of this hormone slows down. The natural growth hormone, also known as somatropin, promotes the growth and development of cells in the muscles, bones and vital organs. It also supports our metabolism, aids recovery and regulates body composition.

While decreased levels of growth hormone are normal as you age, some people suffer from a further HGH deficiency that results in several negative symptoms. Growth hormone injections are a fantastic, low-risk option that can help if you have a human growth hormone deficiency. 

At Harley Street MD, we can evaluate your human growth hormone levels and determine whether you have a growth hormone deficiency. If our doctors believe you would benefit from growth hormone replacement, we may recommend HGH injections to alleviate symptoms and improve your quality of life.

What are the Effects of Human Growth Hormone Deficiency?

Sadly, after the third decade of adult life, growth hormone secretion declines progressively by approximately 15% every decade. If you have adult growth hormone deficiency (AGHD), you  may experience the following symptoms:

• Loss of muscle mass
• Increased abdominal fat
• Lack of energy
• Muscle weakness
• Mood swings
• Low sex drive
• Erectile dysfunction
• Disturbed sleep
• Dry skin
• Slow healing of wounds or injuries
• Memory and cognition problems
• Increased cholesterol levels
• Increased insulin resistance
• Compromised immune system.

Lack of GH can also be a factor in anxiety and depression, weight gain, risk of heart disease and risk of strokes. Many of the symptoms listed can negatively impact the quality of life and become a source of anguish. Some men use growth hormone injections in bodybuilding and sports, but we don’t recommend you try this without medical supervision.

If you feel you might benefit from HGH injections, contact us to book an appointment and discuss your concerns. After evaluation, our medical professionals will develop a bespoke plan that meets your needs. The results will help you start feeling like yourself again and balance out some of the negative symptoms you’ve experienced.

Benefits of Growth Hormone Therapy

If you have a growth hormone deficiency, the benefits of growth hormone replacement therapy will differ for each person. Here are some of the ways it could help:

• Increased muscle mass and strength
• Easier to lose weight and keep it off
• Improved libido and sexual performance
• Improved mood and energy levels
• Better sleep quality
• Lower cholesterol
• Balanced testosterone levels
• Improved bone density
• Better immune system function
• Faster recovery from injuries and wounds

HGH replacement therapy at Harley Street MD is tailored to each patient to provide the best possible results. Most patients will notice that they feel stronger, more mentally sharp and generally reinvigorated with an improved quality of life.

Although you may notice minor changes within the first month of treatment, results are cumulative over time and benefits are most likely to be experienced fully once hormone levels are restored. This is why the time taken to see positive results may vary between individuals.

Am I a Good Candidate for HGH Replacement Therapy?

To determine whether you’re suitable for HGH replacement therapy, a qualified medical professional at our London clinic will perform a full assessment, including blood tests. If you are an adult suffering from symptoms of growth hormone deficiency, you are likely a good candidate for this treatment and would benefit from an initial consultation.

How Does Growth Hormone Replacement Therapy Work?

Growth hormone replacement therapy is an effective treatment to provide the benefits of growth hormone. By using recombinant human growth hormone (rhGH), AGHD can be treated under professional medical supervision with HGH injections and many patients start seeing positive results within weeks.

Harley Street MD is experienced in treating adults suffering from symptoms of growth hormone deficiency, helping them combat negative symptoms. Growth hormone treatment for adults can be done at home (self-administered) or injected by a doctor. For the best results — especially for those with an existing deficiency — treatments may be administered for months or years.

During this time and throughout the entire treatment, we will ensure that you are regularly checked and a doctor monitors your condition. This will include regular blood tests to monitor hormone levels, cholesterol levels, blood sugar levels and bone density.

When selecting a doctor for growth hormone replacement therapy, it’s crucial to choose someone experienced and practised in this treatment process. HGH injections sold online could be counterfeit and if you decide you want to explore this type of hormone treatment, it’s essential that you are monitored closely by a doctor.

Side Effects of Growth Hormone Replacement Therapy

Although growth hormone replacement treatment for adults is usually safe, it’s crucial to be informed of any possible adverse effects. These could consist of:

• Joint stiffness and pain
• Headaches
• Nausea
• Hypothyroidism (underactive thyroid)
• Carpal tunnel syndrome (CTS)
• Peripheral oedema (fluid retention generally in the legs)
• Increased insulin resistance and risk of diabetes
• Gynecomastia (growth of breast tissue in men)
• Liver damage
• Enlarged heart and increased risk of heart disease

Monthly follow-up appointments are recommended to ensure progress and adjust dosage for your safety. A lower dosage or stopping growth hormone injections usually reduces these side effects.  

Growth Hormone Replacement Therapy at Harley Street MD in London

Those with adult growth hormone deficiency may benefit tremendously from HGH injections. We offer a medically supervised programme and will look after you carefully, monitoring your progress closely. If you don’t have AGHD but notice you are experiencing the unpleasant symptoms we discussed earlier, we can still look to see if human growth hormone injections are right for you.

Our growth hormone replacement therapy package begins with a one-hour consultation, full examination and comprehensive laboratory blood tests. It also includes a 30-minute follow-up appointment to educate you on the appropriate HGH administration technique and professional treatment protocol.

How Much Does Growth Hormone Replacement Cost?

The cost for HGH will vary depending on the tests done before prescribing and if you receive an initial appointment and blood testing for growth hormone replacement therapy at our London clinic is £695. During your appointment, the costs of other tests, continued treatment and blood test monitoring will be provided. 

What Is Included with Growth Hormone Treatment for Adults in London?

Your growth hormone replacement therapy programme includes:

  • A one-hour medical consultation and examination with a male doctor to discuss growth hormone replacement therapy, followed by a half-hour consultation after test results.
  • Complete health profile blood tests for anaemia, infection and inflammatory markers, leukaemia, kidney function and electrolyte balance, liver function, bone metabolism, gout and diabetic screen, full cholesterol profile, vitamin D and thyroid function (free T3, free T4 and TSH).
  • Complete hormone profile blood tests: LH, FSH, testosterone, oestradiol, SHBG, prolactin and free androgen index.
