See whether low testosterone may be part of what changed.
Blood tests and doctor reviews are built into your first year of treatment.




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.
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.

Low 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.
Plans start from £90 per month, with injectable testosterone starting from £130 per month. hCG is charged separately. 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.
