A 47-year-old man sits down across from me, hands a printout across the desk, and tells me his primary care physician told him his testosterone is "normal." His total T came back at 410 ng/dL. He sleeps poorly, has put on twenty pounds in the last three years that no amount of training will move, his libido is gone, and he cannot remember the last time he felt sharp at work. The lab is "normal." He is not. I see this almost every week in the clinic, and the conversation that follows is the reason this article exists.
The phrase "testosterone optimization" gets thrown around loosely — sometimes by clinics that hand out 200 mg of testosterone cypionate to anyone with a pulse, sometimes by primary care offices that use a single total testosterone value to declare a man fine when he is anything but. Neither extreme reflects how this should be practiced. After seventeen-plus years in emergency medicine, cardiac ICU, and the cath lab before I moved into hormone medicine full-time, I have a fairly low tolerance for both overtreatment and underrecognition. What follows is how I actually approach men in mid-life when they walk in asking about TRT.
What a real workup looks like
When I evaluate a man for men's testosterone replacement, I do not start with a prescription pad. I start with a panel that gives me enough information to understand the system, not just one marker. The bare minimum I order before I will discuss treatment includes total testosterone, free testosterone, SHBG, estradiol (sensitive assay), LH, FSH, prolactin, DHEA-S, a full thyroid panel (TSH, free T3, free T4, reverse T3, and thyroid antibodies), fasting insulin, HbA1c, a comprehensive metabolic panel, a lipid panel, a CBC with hematocrit, PSA in age-appropriate patients, and hs-CRP.
That looks like a lot of lab work. It is. And it is the difference between treating a number and treating a man. Most of the patients I see who have failed prior testosterone therapy failed because nobody looked at SHBG, nobody looked at estradiol on a sensitive assay, nobody asked whether the testicular axis was suppressed or whether the thyroid was conspiring against them. You cannot fix what you have not measured.
Standard reference ranges for total T in most labs run somewhere around 264 to 916 ng/dL. That range was built across men aged 19 to 100. A 45-year-old at 410 is statistically inside the range and clinically miserable. The range is not the goal. The patient's physiology is.
The mechanisms that actually drive the symptoms
Testosterone production starts at the hypothalamus, runs through the pituitary, and ends at the Leydig cells in the testes. When that signal is intact, LH stimulates the testes to produce testosterone, and a feedback loop keeps it within a working range. Things break in a few characteristic ways, and I sort patients by which break applies to them.
Primary hypogonadism — the testes themselves are not producing. LH is high, FSH is high, total T is low. The pituitary is shouting and nobody is answering. This is the picture I see in men with prior testicular trauma, certain genetic patterns, or a history of mumps orchitis.
Secondary hypogonadism — the signal from above is weak. LH and FSH are low or inappropriately normal, total T is low. The most common drivers I find in middle-aged men in middle Georgia are obesity (adipose tissue aromatizes testosterone to estradiol, which then suppresses the axis), poor sleep (and frankly undiagnosed sleep apnea is rampant in this patient population), opioid exposure, chronic stress with elevated cortisol, and head trauma history. Fort Benning and the broader military community in this region carries a meaningful TBI burden, and I see secondary hypogonadism related to that more often than I would like.
SHBG-driven low free testosterone — total T can look unremarkable, but the man is functionally deficient because most of what he is making is bound up. Aging raises SHBG. Hyperthyroidism raises it. Liver disease raises it. Very low-calorie dieting raises it. I have seen 50-year-old men with total T of 550 and free T well under the functional threshold who feel exactly like a man with overt hypogonadism, because biologically that is what they are.
Estrogen mismanagement. Aromatase converts testosterone to estradiol. Some men aromatize aggressively, especially those carrying central adiposity. If estradiol climbs unchecked, the patient gets nipple sensitivity, water retention, mood symptoms, and ironically a more suppressed HPG axis. Some of the worst TRT outcomes I see in transferred patients are from clinics that ignored estradiol entirely.
The treatment plan that actually works targets the mechanism that is broken. Putting more testosterone into a man whose problem is high SHBG, runaway aromatization, and untreated sleep apnea is not optimization. It is malpractice with extra steps.
What I look for when I read your labs with you
Not sure where to start?
The Start Here pathway walks you through the most common entry points and helps you decide which consultation type is the right fit. Five minutes of self-assessment can save you a wrong-direction conversation.
I do not hand patients a lab printout and walk out. The second visit is sit-down lab review, and there is a pattern I work through every time.
First, I look at total T against where the patient should be for his age and presentation. Then I look at free T (calculated, using the Vermeulen equation, because direct free T assays are unreliable at the lower end of the curve). Then SHBG, because that explains the gap between total and free when one exists. Then estradiol — I want a sensitive (LC-MS/MS) assay, not the standard immunoassay that most outpatient labs default to, because the standard assay is not accurate at the low concentrations we see in men.
LH and FSH tell me whether the axis is intact or suppressed. Prolactin rules out pituitary pathology — anyone with low T and a prolactin north of 25 is getting an MRI before I write a prescription, full stop. DHEA-S gives me a read on adrenal output. Thyroid panel is non-negotiable because untreated hypothyroidism mimics low T almost perfectly and will sabotage any testosterone protocol I run.
Then metabolic markers — fasting insulin, HbA1c, lipids, hs-CRP. Insulin resistance and inflammation both suppress the axis and raise SHBG. PSA and hematocrit set the safety floor, because exogenous testosterone raises both and I will not start a protocol without baselines. CBC matters because TRT can drive secondary erythrocytosis, and a hematocrit creeping above 54% gets my attention from a cardiovascular standpoint — that comes from years of seeing thrombotic events in the cath lab.
When I read all of that together, the right move usually becomes obvious. Sometimes it is testosterone. Sometimes it is treating sleep apnea first. Sometimes it is fixing the thyroid and rechecking in twelve weeks. Sometimes it is referring out for a pituitary workup.
How I run a protocol when TRT is the right answer
I start conservatively. My typical injectable cypionate starting dose is 100 to 120 mg per week, split into twice-weekly subcutaneous injections rather than a single weekly intramuscular dose. The split keeps levels steadier and reduces the estradiol spikes that drive most of the side effects men complain about. For men who prefer not to inject, Biote pellet therapy is a reasonable alternative — pellets give very stable levels over three to five months, which a lot of busy patients prefer.
I do not use HCG or enclomiphene reflexively, but I will use them when fertility preservation matters or when a patient wants to maintain testicular function. I monitor estradiol and use an aromatase inhibitor only when estradiol is clinically high and producing symptoms — not as a routine add-on. Crushing estradiol in a man is its own clinical problem, and I have seen the consequences too many times to participate in that pattern.
Follow-up labs at six to eight weeks. Full reassessment at twelve weeks. Dose adjustment based on data and symptoms together. Then ongoing monitoring at six-month intervals once the patient is stable. Hematocrit, estradiol, PSA, and a lipid panel every reassessment, every time.
Who I will not treat — and why
I tell men no fairly often, and I would rather have that uncomfortable conversation than start a man on a protocol I do not believe will help him. I will not start TRT on a man with active prostate cancer, untreated severe sleep apnea, a hematocrit already above 52%, uncontrolled congestive heart failure, or a history of recent thromboembolism. I will not start TRT on a man who is actively trying to conceive without first having a fertility-preservation conversation. I will not start TRT on a man whose total T came back low one time on a 4 PM draw — testosterone needs to be measured fasting, between 7 and 10 AM, on at least two occasions before I will call it confirmed.
I also will not start TRT on a man whose primary problem is something else entirely. The patient who is sleeping five fragmented hours a night, drinking heavily, eating in a sustained 800-calorie deficit, and under chronic occupational stress does not need testosterone first. He needs the upstream problems addressed. Adding testosterone to that picture buys him a few weeks of feeling better, after which he is back where he started with a new dependency.
The next step that actually matters
If you are a man in Columbus, Warner Robins, or anywhere across middle Georgia who suspects his hormones are part of why he feels the way he does, the concrete next step is straightforward. Get a full panel drawn — fasting, between 7 and 10 AM, ideally on two separate mornings about two weeks apart. The panel should include total T, free T, SHBG, sensitive estradiol, LH, FSH, prolactin, full thyroid, fasting insulin and HbA1c, a CMP, a lipid panel, CBC, and PSA if you are over 40. Bring those results to the consultation.
Book a consultation at the Columbus location or the Warner Robins location. If you are not sure whether you need labs first, the hormone health assessment will route you. Walk in with the data, and we will sit down together and decide what the right move actually is. That is the only way this conversation produces an answer worth having.
