Are You Feeling Like This? — book cover by Gregory S. Allen, MD
From the foreword

"For the first time, I was reading a physician who refused to dismiss what patients know about their own bodies."

— LeeAnn Slade, Gilbert, Arizona
This is for you if

You've been told everything looks fine — but everything doesn't.

If even a few of these feel familiar, you're in the right place. You're not imagining it. And you're far from alone.

The Gray Zone

There is a wide, overlooked space between obviously ill and truly well.

It's where many people keep showing up, keep performing, and keep carrying what needs to be carried — long after they've stopped feeling well. Standard testing matters. But it isn't always the whole story.

Normal on Paper

  • Within standard reference ranges
  • No obvious disease
  • No specific deficiencies flagged
  • Tests come back "clean"
  • Not in active crisis
  • Meets the baseline

Functioning Well in Real Life

  • Steady energy through the day
  • Clarity of mind and easy focus
  • Strong immune resilience
  • Consistent, restful sleep
  • Balanced mood and calm outlook
  • Thriving — not just getting by
Inside the book

What you'll take away

A doctor's clear, compassionate map for the in-between space — written for the person who's still managing, still responsible, still outwardly "okay," but who knows something has changed.

01

Why "normal" isn't the same as optimal

Understand the difference between meeting a baseline reference range and your body actually functioning the way it was designed to — and why so many people fall in the gap.

02

How hormonal signaling really works

A plain-language walk-through of what's happening at the cellular level when energy fades, focus slips, and mood quietly shifts — without quick fixes or simplistic answers.

03

Where standard testing leaves gaps

The places evaluation often falls short, the questions worth asking your doctor, and the broader signals that deserve attention long before a crisis appears on paper.

04

A thoughtful path to restoration

Real, stepwise change — not transformation overnight. How to rebuild steadier energy, clearer thinking, and a stronger sense of being present in your own life again.

About the author

Gregory S. Allen, MD

For most physicians, medicine begins with textbooks. For Dr. Allen, it began with his own health journey — one that looked normal on paper but felt anything but. At nineteen, serving a mission for his church, he was losing his hair, gaining weight, and exhausted in a way nothing explained. Every test came back normal.

That experience followed him through medical school, residency, and into practice — and ultimately changed everything about how he cares for patients. In 2008, one year into practice, he began formal training in hormone optimization. That training has continued for nearly two decades. His approach is unhurried and careful: respecting standard testing, broadening the lens when it's incomplete, and treating people rather than numbers.

Real stories

Six patients who were told their labs were normal — while their bodies asked for something else.

These stories appear in the book's Patient Stories chapter. Each is real — shared with permission, or de-identified and composited to protect patient privacy. Read all six on the stories page.

"I feel so good. I can get through my whole day without needing a nap. I'm actually present with my kids — I can engage, I can play, I can enjoy them again."

The Mother Who Was Running on Empty Told it must be depression · From the book

"I'm excited for each and every day. I'm excited to graduate and excited to move forward with my future — where before it scared me."

The Teenage Girl PCOS and hypothyroidism · From the book

"For the first time, I feel like I'm not broken."

The Woman with Heavy Bleeding Nearly a dozen specialists · From the book

These stories are from the book and are not a prediction of your outcome. Responses to treatment differ widely from person to person; some people improve, some improve only partially, and some do not respond. The book includes a sixth story that did not resolve neatly — on purpose. Nothing here should be read as a promise of results.

The cost of waiting

What happens when this is left unaddressed

Symptoms that go unexplained often go unaddressed. Looking earlier — and more thoroughly — gives you and your physician more to work with.

→

The slow drift

What starts as occasional fatigue and brain fog becomes the new normal. Energy, focus, mood, and motivation continue to fade, often year over year, mistaken for "just aging."

→

Repeat misdiagnosis

Without a deeper look, symptoms get attributed to stress, lifestyle, or a passing season. Real underlying signals stay hidden — and untreated.

→

Changes attributed to age alone

Hormonal signaling influences how we recover, sleep, build muscle, and stay sharp. When a hormonal contribution goes unexamined, those changes are often chalked up to aging without anyone checking.

→

A quieter loss of self

Most painful of all: a slow erosion of the person you used to be — your drive, your joy, your sense of being fully present in your own life.
