“Heading towards 50 years of age, I was unsure whether this treatment would even be an option for me. I knew I had to do something, and I am so glad that this treatment was the path I chose. 6 months into treatment and what a life changer it has been. The team at the Clinic could not have been better.”

“Began TRT in January with this clinic, they have been a pleasure to deal with. Thank you for accommodating the Saturday appointments for me at short notice, its an amazing option instead of trying to take time off work. Amazing service and great team.”

“Overall, great experience, staff were all very informative and helpful. I had been waiting through the GP for months to try and get a blood test as detailed as the one here, so for me it was worth it just for the blood testing alone. Thank you for all of the help and advice.”

What is Testosterone Replacement Therapy (TRT) ?

Testosterone Replacement Therapy is a medically supervised treatment for men with testosterone deficiency. Treatment aims to restore testosterone to an appropriate level and improve symptoms associated with low testosterone.

How do I know if I have low testosterone?

Low testosterone can cause symptoms including reduced energy, low libido, erectile difficulties, reduced strength and muscle mass, increased body fat, difficulty concentrating and changes in mood. Diagnosis requires appropriate blood testing alongside assessment of your symptoms and medical history.

Once your results are available, you will have a consultation with one of our doctors to determine whether TRT is clinically appropriate for you.
