The Testosterone Trap

Read This First

You're tired. Your drive has gone flat. There's more of you around the middle than there used to be, and the gym isn't fixing it. Then an advert, a podcast or a mate at work says the word: testosterone. A quiz online agrees with you. A blood test arrives in the post. Within a week you could have a prescription.

This book is for the week before that prescription, and for the months after it if you've already started.

What this book is

This is a decision book. It is not anti-testosterone and it is not pro-testosterone. Testosterone replacement therapy (TRT) is a real medical treatment that genuinely helps men whose bodies can't make enough testosterone. It is also sold, hard, to men whose bodies make plenty, and to men whose tiredness has a different cause that nobody looked for.

We take three positions all the way through.

We don't judge the decision. Feeling flat, heavy and switched off is real, and wanting it fixed is reasonable.

We don't soften the consequences. Testosterone can thicken your blood, switch off your sperm production, raise your blood pressure and transfer through your skin to your children. We say so plainly, with a source for every number.

We assume you're an adult who may go ahead. So instead of only saying "don't", we tell you how to get tested properly, what to ask, what good monitoring looks like, and the exact signs that mean you stop reading and get emergency help.

What this book won't give you, and why

• No doses, injection schedules or "protocols". Not for testosterone, and not for the add-on drugs some clinics sell alongside it. A dose that is right for one man can thicken another man's blood to danger level. Only a prescriber who has your results can set one.
• No "optimal" or target levels to chase. The guidelines aim for the middle of the normal range in treated men [@endosoc2018plenary; @auaweb2018]. Any number we quote is a threshold for diagnosis, quoted from a guideline so you can judge a result, not a target to aim for.
• No sources, sellers or workarounds. We tell you how to recognise a clinic that is selling rather than diagnosing. We never tell you where to buy.
• It is not medical advice. It can't examine you or read your results. Use it to prepare for a conversation with a clinician who can.

MediQuestAI does not prescribe, sell or dispense any medicine. Brand names (AndroGel®, Testim®, Xyosted®, Jatenzo®, Aveed®, Testopel®, Natesto® and others) belong to their owners and appear only so you can recognise what you're holding. This book is not affiliated with or endorsed by any of them.

If you used anabolic steroids at above-medical amounts for muscle, the companion book Fake Natty covers that in depth. This book is about testosterone as a medicine for low levels.

About the stories

Where a chapter opens with a real event (a regulator's warning, a published trial, a study of online clinics), we say so and cite it.

Some stories are composites; names and details are changed. No composite in this book contains a real patient's words, a real clinic's name or a statistic. The numbers live in the main text, each with its source.

Danger now?

If you're on testosterone, or someone you live with is, and there is chest pain or pressure, sudden breathlessness or coughing blood, one painful swollen calf, a drooping face, a weak arm or slurred speech, a sudden severe headache with changes in vision, an erection that won't go down after four hours, or you can't pass urine at all: stop reading. Call your local emergency number (911 in the US, 999 or 112 in the UK, 999 or 112 in Kenya) or go to the nearest emergency department.

If you're having thoughts of ending your life, call or text 988 in the US, call Samaritans free on 116 123 in the UK and Ireland, or find a line in your country at findahelpline.com.

The full list is on the Go-Now Card at the back of this book. Photograph it now.

Where are you right now?

Tick the one that fits. It tells you where to start.

• Wondering if it's your testosterone (no prescription yet) — Chapters 1, 2 and 3 — 10, then 11
• Holding one result or an online clinic offer — Chapter 2 today — 3, 8, 7, then 11
• Already on TRT — Chapters 5 and 6 (your monitoring) — 7 if you might want children, 9 if you've thought about stopping
• Wanting children now or later — Chapter 7, before anything else — 2, 3, 10
• Thinking about stopping — Chapter 9 — 7, 10
• A partner — Chapters 1, 4 and 7, and the Go-Now Card — Whatever he's facing next

How the book is built

• Chapters 1 to 3 are about whether you actually have low testosterone, and why. Chapter 2 is the testing chapter that every other chapter leans on.
• Chapters 4 to 7 are about the treatment: the different forms, the heart, the blood, the prostate and sleep, and fertility.
• Chapters 8 to 10 are about clinics, stopping, and fixing the cause instead of (or before) treating the number.
• Chapter 11 turns it all into a decision, and the Low-T Decision File at the back gives you a place to record your tests, your causes checklist, your fertility decision, your clinic questions and your monitoring plan.

About this book

This book is educational. It is not medical advice, and it is not a substitute for a clinician who knows your history. If you have warning signs now, use the Go Now card or call your local emergency number. For everything else, take the questions in this book to a doctor, nurse or pharmacist.

The Low-T Marketing Machine

It's 11 p.m. Dan is 41, on the sofa, phone in hand. Work has been brutal for a year. He falls asleep in front of the TV, wakes up at 3 a.m., and is wrecked by mid-afternoon. Sex has become something he and his wife used to do. The belly is new, and the gym isn't touching it.

Between two clips, an advert: Tired? Low drive? Belly that won't shift? You might have low T. Take the 2-minute quiz. He taps it. Do you feel tired? Yes. Less interest in sex? Yes. Weaker erections? Sometimes. Low mood? Some days. Trouble losing weight? God, yes. Less motivated than you used to be? Yes.

Seven out of eight. A green banner: Your answers suggest low testosterone. Below it, a button to order a home blood kit, and a monthly plan "if you qualify". For the first time in months, Dan feels something like relief. It isn't him. It's a hormone. And a hormone can be topped up.

Dan is a composite; names and details are changed.

Here is what the quiz didn't ask Dan. Whether he snores. Whether he stops breathing at night. How much he drinks. What his blood sugar is. Whether the low mood has a name. Whether his father had a heart attack at 50.
