A patient walks into my practice. He is forty-six, runs his own business, lifts four days a week, and six months ago he started testosterone replacement at one of the clinics on the strip that advertises on the radio. The first three months were the best he had felt in a decade. Energy back. Libido back. Mood stable. He told his wife he felt like himself again.
Now he is sitting across from me asking why it stopped working.
A second patient. She is forty-three. Two kids, demanding job, no major medical history. Over the last eighteen months her sleep has fallen apart. She wakes at three in the morning soaked through, lies there until five, and gets up exhausted. Her hair is thinning. Her cycles are still happening but they are unpredictable. She went to her primary care doctor, who told her she was too young for menopause and ordered a TSH. The TSH was normal. She was told to try meditation.
These two patients have the same problem. Not the same hormones, not the same symptoms, but the same underlying clinical failure. They are both being evaluated one hormone at a time, in isolation, by clinicians who are looking at a single instrument when they should be listening to the whole orchestra.
This is what I want to talk about.
The volume TRT clinics in this city, and there are dozens of them, are running a simple business. A man walks in tired. They draw a testosterone level. The level is somewhere in the lower half of the reference range, which for a man over forty is almost always true. They prescribe testosterone cypionate. He feels better. He pays a monthly fee. The clinic moves to the next patient.
I am not against testosterone replacement. I prescribe it constantly. What I am against is pretending that testosterone is the entire endocrine system. Because it is not. It is one hormone in a tightly coupled network of feedback loops that includes the adrenal axis, the thyroid axis, the growth hormone axis, the neurotransmitter precursors that drive mood and motivation, and in women the entire ovarian and progesterone cascade that governs sleep, cognition, bone, and cardiovascular health.
When you give a man testosterone and ignore his cortisol, you are filling one bucket while the other one leaks. When you give a woman estradiol without addressing her progesterone, her thyroid, her DHEA, and her insulin signaling, you are doing the same thing.
The patient who feels great for three months and then plateaus is the patient whose other systems were already struggling. The testosterone bought him time. It did not fix the underlying dysfunction. It just made it possible to ignore for a while.
The human endocrine system is built on three primary hypothalamic-pituitary axes that talk to each other constantly.
The first is the HPG axis, the hypothalamic-pituitary-gonadal axis, which governs testosterone in men and estradiol, progesterone, and the ovarian cycle in women. This is the axis the TRT clinics look at. They look at exactly one output of one axis.
The second is the HPA axis, the hypothalamic-pituitary-adrenal axis, which governs cortisol, DHEA, and the body's stress response. When this axis is dysregulated, and it almost always is in midlife adults living in a stimulated, sleep-deprived, alcohol-tolerant culture, every other hormonal intervention is fighting upstream. Cortisol dysregulation drives insulin resistance, suppresses thyroid conversion, blunts gonadal output, and disrupts sleep architecture. You cannot fix a downstream hormone while the upstream regulator is broken.
The third is the HPT axis, the hypothalamic-pituitary-thyroid axis. The standard primary care evaluation of this axis is a single TSH, which is wildly inadequate. A proper thyroid evaluation includes free T3, free T4, reverse T3, and thyroid antibodies. I see patients every week whose TSH is in range and whose free T3 is at the floor, whose reverse T3 is elevated, and who have been told for years that their thyroid is fine. Their thyroid is not fine. Their thyroid is what is making them tired, cold, constipated, depressed, and unable to lose weight.
These three axes do not operate independently. They are wired together. Cortisol affects thyroid conversion. Thyroid affects sex hormone binding globulin. Sex hormones affect cortisol clearance. If you evaluate one axis without the others, you are reading one page of a three-page document and trying to make sense of the story.
This is where my background changes how I practice.
I spent years in emergency medicine and in military medical contexts where blast exposure and traumatic brain injury were not abstractions. They were the patient in front of me. And the literature on what blast and head injury do to the endocrine system is, frankly, alarming.
The UK BIOSAP study published in the Annals of Neurology examined soldiers with moderate to severe blast traumatic brain injury and found that thirty-two percent of soldiers with blast TBI had anterior pituitary dysfunction, compared to less than three percent of soldiers with non-blast TBI controls. The deficits included growth hormone deficiency, ACTH deficiency, gonadotropin deficiency, and combined dysfunction, and the affected soldiers had measurable cognitive impairment and structural white matter injury on diffusion tensor imaging. These were young men, median age twenty-eight, with broken pituitary glands they did not know they had. nih
A separate study of US veterans with blast-related mild TBI found something even more clinically relevant for the civilian population. Thirty-one percent of veterans with blast-related concussion screened positive for one or more neuroendocrine disorders, and the symptoms of post-concussive hypopituitarism overlapped almost completely with the symptoms of PTSD. Cognitive deficits, mood and anxiety disorders, sleep problems, body composition changes, and increased cardiovascular mortality. The authors concluded that many of these symptoms, when caused by pituitary dysfunction, can be alleviated by hormone replacement. Let that sit for a moment. A meaningful fraction of what we call PTSD in returning veterans may in fact be untreated post-traumatic hypopituitarism. nih
And it is not just blast and not just severe injury. More recent animal work has shown that repeated mild concussive impacts produce a delayed but sustained dysregulation of the HPA axis, with ACTH levels still significantly elevated thirty days after injury. This matters for anyone who has played contact sports, who has been in a car accident, who has fallen off a ladder, who has been a soldier, a boxer, a wrestler, a snowboarder, a cyclist who took a hard fall they shrugged off in their twenties.

When I see a forty-five-year-old man with low testosterone, low energy, poor sleep, and weight gain, I do not just ask about his diet and his lifting routine. I ask about his head. I ask if he played football in high school. I ask if he was ever knocked out, even briefly. I ask if he served. Because the etiology of his endocrine dysfunction may not be aging. It may be an injury he stopped thinking about twenty years ago, and the answer is not just testosterone. The answer is a full pituitary evaluation.
This is not exotic medicine. This is what the literature has been telling us for over a decade. It is just that nobody is doing it.
I want to spend real time here, because the undertreatment of women is the single largest unaddressed problem in adult medicine and I will not pretend otherwise.
For two decades, women have been told that hormone replacement is dangerous, that they should suffer through their symptoms, that the risks outweigh the benefits. This is the long shadow of the Women's Health Initiative, a study that used oral conjugated equine estrogens and synthetic medroxyprogesterone in women whose average age was sixty-three, more than a decade past their menopause. The findings of that study were then generalized, badly, to every woman of every age using every form of hormone therapy, and a generation of women paid for it with their sleep, their cognition, their bones, and their lives.
The science has moved on. The clinicians, mostly, have not.
Here is what the current literature shows. The timing hypothesis, supported by randomized controlled trials, primate models, and large observational cohorts, demonstrates that hormone therapy initiated within ten years of menopause onset or before age sixty is associated with reduced cardiovascular risk, not increased risk. The Nurses' Health Study reanalysis showed a reduced risk of coronary heart disease in women who started hormone therapy within four years of menopause compared to those who started after ten years. A meta-analysis of fifty-one studies by Dr. Lisa Mosconi and colleagues found that midlife estrogen therapy was associated with a thirty-two percent lower rate of dementia, while late-life initiation showed no significant protective effect.

Read that again. A thirty-two percent reduction in dementia in women who started estrogen at the right time. There is no drug on the planet, no supplement, no lifestyle intervention with that effect size for dementia prevention. None. And we have spent twenty years telling women they cannot have it.
The route matters too. Transdermal bioidentical estradiol carries a two to four times lower risk of venous thromboembolism than oral estrogen. The progestogen matters. Bioidentical progesterone is not the same molecule as medroxyprogesterone acetate, and the safety profile is not the same. MAAM Medical
The perimenopausal woman with the three in the morning night sweats, the brain fog, the unpredictable cycles, the new anxiety, the joint pain, the libido in the basement, is not crazy. She is not too young. She is not being dramatic. Her ovaries are failing on a timeline that is decades long, and the medicine that can give her back her sleep, her cognition, her cardiovascular protection, and her bone density is sitting on the shelf because somebody read the abstract of a 2002 paper and stopped reading.
I take care of these women. Aggressively. I take care of their husbands too, and I want them treated together because the data on quality of relationships, sleep, and longevity when both partners are optimized is not subtle. But the women come first in this conversation because they have been waiting the longest.
When a patient comes to Outlive Concierge Medicine for hormone optimization, I am not running a testosterone level and writing a script. I am running a panel that maps all three axes, looks at thyroid conversion in detail, evaluates adrenal output across the diurnal curve, screens for pituitary insufficiency in anyone with a history of head injury, evaluates insulin and metabolic status because endocrine dysfunction and metabolic dysfunction are the same conversation, and in women does a proper evaluation of ovarian reserve and the full sex hormone cascade including estradiol, progesterone, DHEA, and pregnenolone.
I am also taking a real history. Sleep, stress, alcohol, training load, head injuries, family history, medications, supplements, and the actual lived texture of the patient's daily life. The lab data is meaningless without the clinical picture. The clinical picture is incomplete without the lab data.
Then I build a protocol. Sometimes it includes testosterone. Sometimes it includes estradiol and progesterone. Often it includes thyroid optimization. Sometimes it requires addressing cortisol and sleep before any other hormone is touched, because trying to optimize sex hormones in a patient whose HPA axis is in chaos is a waste of everyone's time and money.
This is the work. It is slower than the clinic on Sahara. It is more expensive than the clinic on Sahara. And it is the only version of this medicine that I am willing to practice.
You are probably the patient I am describing. The man who feels worse than he should. The woman who has been told to meditate. The forty-something who knows something is wrong and has not yet found someone willing to actually look.
I am taking new patients. The consultation is a real conversation about your physiology, your history, your goals, and what a complete evaluation would look like for you. If that is the kind of medicine you want, reach out.
