London & Surrey clinics
Testosterone runs far beyond libido.
When levels drift below your optimal range, the effects arrive slowly and get written off as “just getting older.” They rarely are. Low testosterone is common, under-diagnosed and treatable.
Persistent fatigue, flat motivation and a quiet loss of edge.
Stubborn belly fat, slower recovery and declining lean muscle.
Brain fog, low mood, poor sleep and reduced confidence.
Four things a standard London TRT service can’t give you.
Our protocol is built on a clinical Standard Operating Procedure - the same governance a hospital service runs on, applied to hormone optimisation.
Optimise, don’t just replace
We target your optimal free-testosterone range - a defined goal, not just the bottom of a lab reference interval.
Fertility preserved
An optional hCG protocol keeps your own testicular function switched on - so treatment need not cost you fertility.
Precision microdosing
Small, steady subcutaneous doses flatten the peaks and troughs - smoother levels, fewer side effects.
Monitored & governed
Doctor-led, pharmacist-supported, CQC-registered - scheduled bloods and reviews at every stage.
Six clear steps. Nothing begins until you’re ready.
A structured pathway drawn straight from clinical protocol - so you always know what happens next and why.
Hormone Assessment
Start online in minutes with our validated symptom checker, or speak to our team. It tells us whether a consultation is worth your time.
Doctor Consultation
A full clinical history with a specialist doctor - in person at a London or Surrey clinic, or via video. We’ll discuss symptoms, goals, medical background and fertility plans.
Comprehensive Blood Screen
A baseline panel well beyond a single testosterone number - the full hormonal, metabolic and safety picture a precise plan requires.
Your Personalised Plan
Formulation, dose, timing and fertility strategy - designed around your biology, not a template.
Review & Agree Together
We walk through the plan until you’re comfortable, answer every question and confirm consent before anything begins.
Ongoing Optimisation
Repeat bloods and review every 2–3 months, fine-tuning your protocol as your body responds over time.
Every route is precise.
Subcutaneous Microdosing
Small self-administered injections, typically twice weekly, just under the skin. Our preferred route for steady levels.
- ✓Smoothest, most stable levels
- ✓Blunts peaks that drive side effects
- ✓Quick to fine-tune or reverse
Topical Gels
A daily gel applied to the skin. Needle-free and simple, suited to patients who prefer to avoid injections.
- ✓No injections
- ✓Easy daily routine
- ✓Requires care around skin transfer
Long-Acting Injection
A depot injection given far less frequently. Maximum convenience for stable, well-monitored patients.
- ✓Infrequent dosing
- ✓Low day-to-day effort
- ✓Less flexible once given
Every option is paired with our fertility-preservation protocol. Your doctor sets the exact formulation and dose from your bloods - never a fixed package.
Stay optimised - without switching off fertility.
Conventional TRT can suppress the body’s own testosterone and sperm production. For many men - especially those who may want children - that’s a dealbreaker. It doesn’t have to be.
Alongside testosterone, we run an optional hCG protocol that keeps the testes active and the natural pathway working. It’s a defining part of how we practise, and a conversation with every patient - not an afterthought.

Testosterone is a foundation. It isn’t the whole answer.
Erections, drive and performance depend on hormones, blood flow, nerves, mind and relationship - all at once. Optimising testosterone often transforms things; where it doesn’t fully, our dedicated sexual optimisation service takes over.
Erectile Function
Full assessment of the vascular, hormonal and neurological drivers of erectile difficulty - then a plan matched to the cause, not a one-size pill.
Regenerative Therapies
Beyond medication: regenerative and blood-flow treatments that work on the underlying tissue and circulation to restore function.
Libido, Mind & Performance
Desire, confidence, sleep and stress all feed performance. We address the psychological and lifestyle picture alongside the physical.
A dedicated pathway - not an afterthought
Sexual health is optimised deliberately at Levitas, bringing hormones, regenerative therapy and performance support into one plan rather than leaving it to chance alongside TRT.
Powerful medicine deserves proper oversight.
TRT is safe and effective when done properly. “Properly” means the right diagnosis, the right targets, and monitoring that never stops.
What we track - and target
Testosterone can thicken blood by stimulating red-cell production - that’s the single most important safety number in TRT. We check haematocrit before you start and at every review. If it climbs too high, we act: reducing dose, adjusting route, spacing injections or pausing, rather than pressing on regardless.
There is no standard dose. We shape the protocol around your personal risks and deliberately manage peaks and troughs - using small, frequent subcutaneous doses to flatten the surges that drive side effects and the dips that bring symptoms back.
Every plan is prescribed and reviewed by a specialist doctor within a regulated service.
Structured recall schedules your bloods and reviews and chases them - monitoring never lapses once you feel better.
A dedicated pharmacist oversees your prescription, preparation and dispensing.
We collaborate with your GP and specialists - urology, cardiology, endocrinology, fertility - so your care stays joined up.
Clear conversations about benefits, cardiovascular safety and fertility - no hype.
We agree up front what would prompt us to pause or stop - safety limits set before you begin, not improvised.

What our patients say.
The things men ask us most.
Will TRT make me infertile?+
It can suppress the body’s own sperm production - exactly why we offer an optional hCG protocol to help preserve fertility alongside therapy. If children are on the horizon, tell us at consultation and we’ll build the plan around it.
How is your London TRT service different from a standard high-street clinic?+
Unlike standard high-street providers, our TRT treatment in London and Surrey is built on a strict clinical Standard Operating Procedure - doctor-led, pharmacist-supported and CQC-registered, with monitoring that never lapses.
Is TRT safe?+
When correctly diagnosed, dosed and monitored, TRT has a strong safety record. The job is in the "correctly" - right baseline diagnosis, sensible targets, and scheduled bloods to track markers like haematocrit, oestradiol and PSA to catch and manage anything early.
Injections or gel - which is better?+
There’s no universal answer. We often favour small, twice-weekly subcutaneous injections for the steadiest levels, but gels suit patients who prefer to avoid needles. Your bloods, lifestyle and preference decide - we choose together.
How soon will I feel a difference?+
Some men notice energy and mood changes within a few weeks, while body composition and libido changes typically build over the first few months. We review at 2–3 months with repeat bloods to fine-tune from there.
How do I start?+
Take our 10-minute online hormone assessment or book a consultation directly. If TRT isn’t right for you, we’ll tell you plainly and point you toward whatever is.
