TRT · 8 min read · Published 2026-03-10
Testosterone replacement therapy has moved from the margins to the mainstream. Across London, more men are seeking treatment for symptoms they once dismissed as inevitable ageing. But with this surge in demand has come a proliferation of clinics — many of them operating online with minimal medical oversight.
Understanding what separates responsible, evidence-based TRT from reckless prescribing could be the most important health decision you make this decade.
TRT involves supplementing your body's natural testosterone production when it falls below optimal levels. This can be administered via:
The goal isn't to push testosterone to supraphysiological levels — it's to restore you to the optimal range where you feel and function at your best.
TRT is appropriate for men with clinically confirmed low testosterone (hypogonadism), typically characterised by:
Crucially, TRT is not a lifestyle choice or a performance-enhancing shortcut. It's a medical treatment that requires proper diagnosis, ongoing monitoring, and clinical expertise.
Some online clinics use questionnaire-based algorithms to prescribe TRT with minimal clinical assessment. At The 35+ Club in Chelsea, every patient is assessed face-to-face by a GMC-registered doctor who reviews comprehensive blood work, medical history, and current symptoms.
A single testosterone reading is insufficient. Proper assessment includes:
TRT isn't a "set and forget" treatment. Regular blood tests (typically every 3–6 months) are essential to ensure levels remain optimal and to monitor for potential side effects such as elevated haematocrit or changes in PSA.
Any responsible TRT provider should include prostate health monitoring as part of their programme. At our Chelsea clinic, this is built into every membership tier.
Prices vary significantly across London. Be wary of clinics offering suspiciously cheap packages — they often cut corners on blood testing or medical oversight. Equally, some Harley Street practices charge premium prices for the same standard of care available elsewhere.
At The 35+ Club, our membership model includes all consultations, blood work, and ongoing monitoring in a transparent monthly fee, so there are no hidden costs.
Chelsea has long been associated with premium healthcare. Our Ives Street location offers privacy, convenience, and the reassurance of being treated in a proper clinical environment — not a rented WeWork office or a video call from a remote prescriber.
TRT can be genuinely life-changing when prescribed and monitored correctly. The key is choosing a clinic that prioritises your long-term health over quick profits. If you're considering TRT in London, start with a proper assessment — the data will guide the decision.
