Sentinel · Hormone monitoring
Stay strong for years, not just for now.
You use these compounds to be stronger, leaner, and on top of your game. Sentinel is how you stay there without your heart, your blood, or your long-term health quietly paying for it. One doctor, watching the things that go wrong slowly.
£250 a month, or £125 alongside practice membership.
Why it matters
The harm you can't feel, and won't see coming.
You take these compounds for a reason: strength, performance, how you look and feel. The thing that takes all of that away is the complication you didn't see coming.
Most of the harm these compounds can do builds quietly. Your blood gets thicker. Your heart works harder. Your cholesterol shifts. None of it hurts and none of it shows, right up until the day it does. The men who get caught out aren't reckless. They just had nobody watching the right things at the right time.
Monitoring is how you keep the upside without paying for it later. I track what these compounds put under strain, often enough to catch a problem while it's still easy to fix. You carry on doing what you do, knowing a doctor has eyes on the parts that matter. That's the difference between hoping you're fine and knowing you are.
What you get
Close monitoring, managed by one doctor.
Sentinel is built on continuity: the same doctor, the right tests for where you are, tracked over time, with a clear read on every result.
A thorough baseline
We start face to face with a full history, examination, and testing across every system these compounds put under strain, from heart and blood to hormones, liver and metabolism. It's the reference point everything afterwards is measured against.
Reviews through the year
Regular reviews, usually quarterly and sooner when a result is moving. I book them, so you never chase. Most can be done remotely; you come in once a year, and any time a result means I need to see you.
Every result explained
I read your bloods myself and tell you what they mean in plain terms, including tests you've run elsewhere. A clear read on where you stand, not a page of numbers.
The right tests, not a fixed panel
What I track depends on what you're using and how your results move. I test what's under strain and skip what isn't, so every check earns its place and you're never paying for tests you don't need.
A direct line to me
Between reviews you can reach me about a result, a worry, or a change to your plan, without booking a full appointment.
Bloods at cost
You pay the lab price for your bloods with nothing added, and the blood draw at each review is included. You're paying me for the oversight, not a markup on tests.
The boundary
Monitoring and harm reduction. Nothing sold on the side.
Where there's a clear medical reason, I prescribe and manage testosterone replacement, and I watch your safety on it closely. What I won't do is prescribe or supply the performance compounds, or advise you on cycles, doses or stacks. If you use those, my job is to measure what they're doing to you and keep you as safe as that choice allows.
That boundary sits in the service agreement, and you sign it at the start. It's what makes this real medicine rather than a shortcut, and it's the reason you can trust the oversight you're paying for.
What it's worth
Protect what you've worked for.
A doctor watching the things that harm you slowly, catching them while they're still easy to fix. So you keep training, keep performing, and keep everything you've built, without it quietly costing your health down the line.
Sentinel
The oversight that keeps you safe inside the choice you've made. Your first appointment is in person and part of the fee, not a separate charge.
- The in-person start, the reviews and the direct line, all in the fee
- Reviews usually quarterly, and sooner when a result is moving
- Testosterone replacement prescribed and managed when there's a clear medical reason, kept in a healthy range and adjusted to how you feel and what your bloods show, never on request alone
- Your bloods and any imaging at cost, never marked up, with the blood draw included
Already in the practice?
Sentinel runs alongside your membership at £125 a month. It's charged separately and never folded in, because its scope, the consent it needs and the extra risk it carries are its own.
Sentinel covers monitoring and the medical steps that keep you safe on what you're taking. It isn't general practice for acute or everyday illness, and it doesn't include prescribing the compounds or advising on how you use them.
Sentinel and the practice
One thing, done closely.
Sentinel does one job and does it closely. It keeps you training hard and feeling strong while it catches the harm these compounds do quietly, on the tight schedule a man actively using them needs. It doesn't cover acute care or everyday illness.
Sentinel and the practice membership are two different things for two different people. Sentinel watches one risk closely, on the schedule a man using these compounds needs. Membership is proactive medicine for the whole of your life, with a yearly assessment and a plan built around where your health is heading. Most men take Sentinel on its own. If you want both, Sentinel runs alongside your membership at the member rate.
Common questions
Straight answers, no judgement.
Will you judge me for using these compounds?
No. You've made an informed decision and you're an adult. My job isn't to talk you out of it, it's to make sure you understand what's happening inside your body and to act on it before something becomes a problem. You'll get straight clinical information, not a lecture.
Do you prescribe anabolics or advise on cycles?
No anabolics, and no advice on cycles. I don't prescribe or supply the performance compounds, and I won't tell you what to run or at what dose. Testosterone replacement is a separate matter: where there's a clear medical reason for it, I prescribe and manage that, and watch your safety on it. The firm line is the performance compounds, and it's what keeps the service defensible for both of us.
Is any of this legal?
Yes. Possessing these compounds for your own use isn't a criminal offence in the UK. Supplying them is, and so is importing them by post, but neither of those is what this is. Sentinel is medical monitoring and, where it's warranted, testosterone replacement, both straightforward, legal and good medicine. I prescribe testosterone replacement only on a clear medical indication, and I don't prescribe or supply the performance compounds. Watching your health and keeping you safe is simply good medical care.
I already run my own bloods. Why do I need you?
Tracking numbers is the easy part, and you can already do that yourself. What you can't do for yourself is the rest of it: spotting a pattern forming across your results before any single one looks wrong, reading a number against your symptoms, your training, your history and what you're actually taking, examining you when something needs a closer look, and deciding what to act on and when. That's clinical judgement, and it's the whole point of a doctor rather than a spreadsheet or an app. Your bloods tell you something changed. I tell you what it means for you, and what to do about it. More in why normal blood tests can still miss real harm on testosterone.
Will this be visible to my NHS GP?
Only with your consent. This is a private, confidential service. I'd always encourage joined-up care and I'm happy to write to your GP if you want that, but nothing is shared without your say-so. More in can your NHS GP know about your testosterone use?.
What do you actually monitor?
The things these compounds put under strain: how thick your blood is getting, your cholesterol and heart-risk markers, your liver and kidneys, your blood sugar, your full hormone levels, your prostate marker, signs of inflammation, and a blood-borne virus screen where it's relevant. The exact tests depend on what you're using and how your results move over time. I'll always tell you why we're checking something.
