NOT FEELING LIKE YOURSELF?
Low energy
Low sex drive
Mood changes
Less muscle mass
Poor sleep
Low motivation
Erectile difficulties
More body fat
These symptoms can have several causes. A blood test and clinical assessment help establish what’s behind them. Clinical guidance
Sex drive, erections, energy, recovery and mood can all change. But symptoms alone cannot confirm the cause.Source: EAU guidance on symptoms.
Diagnosis combines your symptoms with low morning testosterone on two separate blood tests.Source: EAU diagnostic guidance.
A wider blood panel helps clarify the cause before your doctor recommends TRT or another route, with your health and fertility plans in view.Source: Endocrine Society diagnostic guidance.
Our plan includes your prescribed medication and everything needed to take it - including syringes, wipes and a sharps bin where applicable. It also covers blood tests and doctor reviews at 6 weeks, 3 months, 6 months and 12 months, followed by six-monthly monitoring for as long as you remain on treatment.
What to expect from TRT
Reported experiences and timelines vary. TRT is intended for appropriately diagnosed testosterone deficiency and does not guarantee improvements in energy, cognition, sexual function or body composition. Clinician assessment and ongoing monitoring are required and included.
Check My TestosteroneSexual interest can be one of the first changes. Some men also report a brighter mood, clearer focus and a renewed sense of drive.
Desire, confidence, motivation and concentration may feel more consistent. Fatigue and “brain fog” may begin to ease.
Strength and lean mass may begin to rise as fat mass starts to fall. Mood, sexual satisfaction and everyday wellbeing can continue improving.
Changes in strength and body composition become more established, sexual wellbeing may continue to improve, and bone health begins building beneath the surface.
A complete review brings the transformation into focus—how you feel, how you perform and what your monitored results show.
WHAT’S NEXT?
Start with a home test. If low, a blood panel checks the wider picture.
Your doctor reviews your results, symptoms and health history to assess whether TRT is right for you.
If prescribed, medication is delivered to your door, with blood tests and doctor reviews built in.
Treatment is subject to clinical assessment, with a three-month minimum.
31% of men surveyed reported low libido.
55% were unfamiliar with the symptoms of low testosterone.

Understand the symptoms, possible causes and steps to diagnosis.
Read guideLow testosterone—also called testosterone deficiency or hypogonadism—is diagnosed when relevant symptoms are supported by repeatedly low morning testosterone results. One low result is not enough.Source: EAU definition and diagnosis.
Lower sex drive, fewer morning erections and erectile difficulties are the most specific signs. Lower energy, strength, motivation or concentration can also occur, but these symptoms have other possible causes.Source: EAU guidance on symptoms.
The four-marker finger-prick test is an initial check, not a final diagnosis. A low or borderline result needs confirmation with morning venous tests on separate occasions before treatment is considered.Source: Endocrine Society diagnostic guidance.
A borderline result may need repeating or investigating with a wider blood panel. If your testosterone is normal, TRT may not be appropriate and other explanations for your symptoms should be considered.Source: EAU repeat-testing guidance.
TRT may be considered for adult men with relevant symptoms and consistently low testosterone. Your medical history, current medication, cardiovascular health, prostate health and fertility plans are reviewed first.Source: Endocrine Society treatment criteria.
No. TRT uses prescribed testosterone to restore confirmed low levels to a monitored range. Non-medical anabolic steroid use commonly aims for much higher levels without the same clinical controls.Source: EAU guidance on therapeutic testosterone.
Your doctor considers your symptoms, blood results, health and fertility plans. They explain the suitable routes, risks and full recurring cost before anything is prescribed.Source: Endocrine Society treatment guidance.
Yes. Standard TRT can suppress sperm production and may not be appropriate if you are trying for a child. Tell your doctor before starting so fertility-preserving options can be included.Source: EAU guidance on TRT and fertility.
Response is assessed over months, not days. Some sexual symptoms may change earlier, while changes in body composition can take longer. Treatment continues only when your symptoms and results support it.Source: Review of TRT response timelines.
Current evidence has not shown that properly prescribed TRT increases prostate cancer risk, but long-term evidence remains limited. PSA and prostate health are assessed where appropriate, and TRT is not normally prescribed to men with active prostate cancer.Source: EAU prostate safety guidance.
Your cardiovascular history and risk factors are reviewed before treatment. Men with heart disease, heart failure or a history of blood clots may need additional assessment and closer monitoring.Source: TRAVERSE cardiovascular safety trial.
Your plan includes your prescribed medication and everything required to take it—including syringes, wipes and a sharps bin where applicable. Scheduled blood tests and doctor reviews are also included. hCG and any additional services are charged separately.
Request your personalised quote. hCG is charged separately. TRT is billed monthly with a minimum three-month contract. If you cancel during that minimum term, the remaining payments for the agreed term are still due, subject to your statutory rights. Your full recurring cost is shown before treatment is prescribed.
Yes, subject to clinical review. You will need to provide your current prescription, treatment schedule and recent blood results. A Heracles doctor will confirm whether your existing treatment can safely continue.
