Testosterone falls about 1% a year after age 30. That statistic drives an entire industry, and it explains almost nothing about why a specific 47-year-old feels flat. The symptoms men bring in — fatigue, low libido, thickening waist, poor recovery, dulled mood — are produced by at least six different mechanisms, and testosterone is only one of them.
The practical problem is that most men get one lab value, total testosterone, drawn at whatever hour they showed up, and a yes-or-no answer built on it. That test is the least informative part of the panel. This hub covers the labs that actually resolve the picture, the reversible causes worth ruling out first, how treatment options differ once therapy is genuinely indicated, and how to tell a clinic doing medicine from one running a subscription.
The Verdict
The full panel — and why total testosterone alone misleads
Around 98% of the testosterone in your blood is bound to a carrier protein and cannot act on tissue. Sex hormone-binding globulin holds most of it tightly; albumin holds the rest loosely. Only the small free fraction, plus the loosely-bound portion, does the work. SHBG rises with age, with thyroid overactivity, with liver disease and with some medications — so a man's total testosterone can hold steady for a decade while the fraction he can actually use quietly declines.
That is the core reason a normal total does not rule out a hormone problem. It is also why the panel below is read as a set. LH tells you whether the testes or the pituitary is the source. Estradiol tells you whether aromatization is running high. PSA and hematocrit are the safety floor before anything gets prescribed.
| Marker | Typical adult male range | What it tells you |
|---|---|---|
| Total testosterone | 300–1,000 ng/dL (lab reference) | Measures bound plus unbound hormone. Draw before 10am, fasted, on two separate days. A single afternoon draw can read 100–200 ng/dL below a morning draw on the same man. |
| Free testosterone | ~1.5–2.5% of total; roughly 9–25 pg/mL | The fraction actually available to tissue. Calculated free T from total, SHBG and albumin is more reproducible than most direct assays. |
| SHBG | 10–57 nmol/L | The binding protein that decides how much of your total is usable. High SHBG with normal total is the classic pattern behind symptoms that get dismissed. |
| LH | 1.7–8.6 IU/L | Separates primary from secondary hypogonadism. Low T with low LH points at the pituitary or hypothalamus, not the testes. |
| FSH | 1.5–12.4 IU/L | Reflects sperm production signalling. Matters if fertility is a current or future concern, because TRT suppresses it. |
| Estradiol (sensitive assay) | 10–40 pg/mL in men | Men need estradiol for bone, libido and mood. Order the LC/MS sensitive assay — the standard immunoassay is validated for female ranges and misreads male levels. |
| PSA | Under 4.0 ng/mL; under 2.5 if under 50 | Baseline before any testosterone therapy, then rechecked. A rise over 1.4 ng/dL in a year warrants urology input. |
| Hematocrit | 38.3–48.6% | The main safety lab on TRT. Above roughly 54% most prescribers dose-reduce or pause. |
The men's hormone panel guide takes each of these markers in turn — what it adds, when it is worth paying for, and the ordering details that decide whether the result is usable.
Rule these out before testosterone therapy
Low testosterone is frequently a downstream signal rather than the root problem. Several of the upstream causes are reversible, and reversing them can raise levels enough that lifelong therapy stops being the question. The cost of checking is a few weeks and a few tests. The cost of skipping the check is a prescription you may be on permanently, having suppressed your own production to get there.
| Cause | How to check it | Why it matters |
|---|---|---|
| Obstructive sleep apnea | Home sleep test or in-lab study | Untreated OSA suppresses the overnight LH pulses that drive testosterone production. Treating it can raise total T without any hormone prescription. |
| Excess body fat | Waist circumference, body composition | Adipose tissue converts testosterone to estradiol via aromatase. Losing 10% of body weight has been associated with roughly a 2–3 nmol/L rise in total testosterone. |
| Thyroid dysfunction | TSH, free T4, free T3, TPO antibodies | Hypothyroid symptoms — fatigue, low libido, brain fog, weight gain — overlap almost perfectly with low testosterone symptoms. |
| Medications | Full medication review | Opioids, long-term glucocorticoids, some antifungals, and finasteride can all move testosterone or the symptoms attributed to it. |
| Alcohol and chronic short sleep | Sleep tracking, intake log | One week of five-hour nights has been shown to drop daytime testosterone by 10–15% in healthy young men. |
| Iron overload or deficiency | Ferritin, transferrin saturation | Hemochromatosis is an uncommon but genuinely reversible cause of secondary hypogonadism. |
| Prolactin excess | Serum prolactin | A prolactinoma is rare, but it is the reason low T with low LH should never go straight to a prescription. |
Sleep apnea deserves particular attention because the overlap with low-testosterone symptoms is near-total — daytime fatigue, low mood, poor concentration, weight gain, reduced libido — and because testosterone therapy can worsen untreated apnea rather than help it. Any man carrying extra weight around the neck and waist who snores should be tested before hormones enter the conversation.
TRT delivery methods and their tradeoffs
Once therapy is genuinely indicated, the delivery method shapes the experience more than the molecule does. All the common options deliver testosterone; they differ in how steady the levels stay, how reversible a dosing mistake is, what it costs, and what daily task it adds. Prices below are typical US self-pay ranges for the medication and dispensing, not including consults or labs.
| Method | Frequency | Typical cost | Tradeoff |
|---|---|---|---|
| Intramuscular or subcutaneous injection | Weekly, or split twice weekly | $30–$100/mo for the drug | Cheapest and most predictable. Twice-weekly dosing flattens the peak-to-trough swing that causes mood and energy roller-coasters on a once-every-two-weeks schedule. |
| Transdermal gel or cream | Daily | $40–$300/mo depending on brand vs compounded | Steady daily levels, no needles. Real transfer risk to partners and children through skin contact; absorption varies widely between men. |
| Subcutaneous pellets | Every 3–5 months | $500–$1,000 per insertion | No daily task. The tradeoff is control: if the dose runs high, it cannot be reduced until the pellets exhaust. Extrusion and site infection happen in a small share of insertions. |
| Oral (undecanoate capsules) | Twice daily with food | $200–$600/mo | Avoids the older liver-toxic oral forms. Requires a fat-containing meal, and blood-pressure monitoring is part of the label. |
| Nasal gel | Two to three times daily | $300–$500/mo | Shorter suppression of the pituitary axis, which some men choose for fertility reasons. The dosing frequency is the reason adherence tends to be poor. |
The non-obvious one is pellets. They are marketed on convenience, and the convenience is real. But a pellet dose cannot be walked back. If hematocrit climbs or estradiol runs high six weeks after insertion, the options are to manage around it or to have the pellets surgically removed. With injections or creams, the same problem is a dose adjustment next week. For a first year on therapy, when the right dose is still being found, that reversibility is worth more than the convenience.
What separates a real clinic from a prescription mill
The distinction is not price, branding, or whether the visit is virtual. It is how much work happens before the prescription and how much monitoring happens after. Telehealth clinics can run excellent protocols and in-person clinics can run poor ones. The six signals below are what to check.
| Signal | What a real clinic does | What a mill does |
|---|---|---|
| Full baseline panel before prescribing | Total and free T, SHBG, LH, FSH, estradiol, PSA, CBC, metabolic panel, thyroid | Total testosterone alone, or a single questionnaire |
| Two confirming morning draws | Diagnosis requires two low morning values on separate days | One draw, any time of day, then a same-visit prescription |
| Reversible causes ruled out | Sleep, weight, medications, thyroid, prolactin addressed first | No discussion of anything except the hormone |
| Fertility conversation | Sperm banking or HCG discussed before starting | Fertility never raised |
| Ongoing monitoring | Hematocrit, PSA, estradiol and levels rechecked at 6–12 weeks then every 6–12 months | Labs only if you ask, or billed separately every time |
| Exit plan | A stated protocol for stopping or restarting | No discussion of what happens if you stop |
Physician-led optimization platforms differ meaningfully from each other on these points, and on price. The ones with a men's hormone focus are, alphabetically: Fountain Life, Hone Health, Lifeforce, Marek Health, Maximus, and Opt Health. Ordering carries no editorial meaning. Each is reviewed on this site against the same rubric, so the panels, consult structure, monitoring cadence and cost sit side by side.

Realistic cost bands
Three separate costs make up the total, and clinics bundle them differently, which is what makes advertised pricing hard to compare.
- Diagnostics. A full hormone panel self-pay runs roughly $150–$400. Ongoing monitoring adds two to four panels a year. Some programs include labs in the membership; some bill each draw.
- Medication. Generic injectable testosterone cypionate is $30–$100 a month. Compounded creams run $40–$150. Branded oral and nasal forms run $200–$600. Pellets are $500–$1,000 per insertion, three to four times a year.
- Clinical care. Membership or consult fees are where programs diverge most, from about $100 to $400 a month. All-in, most men on a physician-supervised protocol land between $150 and $400 a month.
Insurance sometimes covers testosterone therapy when documented hypogonadism is on the chart with two confirming morning draws — which is another reason the diagnostic sequence matters. Cash-pay optimization programs generally do not bill insurance at all.
Who can prescribe testosterone therapy, and how to get it
Any licensed prescriber with prescriptive authority in your state can write for testosterone — that includes primary care physicians, endocrinologists, urologists, and in most states nurse practitioners and physician assistants. Testosterone is a Schedule III controlled substance in the US, which adds prescription and refill restrictions but does not restrict it to a specialty.
Four routes lead to a prescription, and they differ mainly in how much diagnostic rigour sits in front of them. Your own primary care physician is the cheapest route and the one most likely to be covered by insurance, though many will refer rather than manage titration themselves. An endocrinologist or urologist is the appropriate route when the panel suggests a secondary cause, or when fertility is a consideration. A physician-led optimization programme bundles the panel, the prescription, and the retest cadence into one membership. A telehealth platform is the fastest and the most variable — the diagnostic sequence in front of the prescription is where these differ most.
Insurance generally follows documentation rather than symptoms. Coverage typically requires low testosterone confirmed on two separate morning draws with a documented diagnosis on the chart, which is why the diagnostic sequence above is worth doing properly even if you intend to pay cash. Cash-pay optimization programmes usually do not bill insurance at all, and their medication costs sit outside the membership. Doctor-led options compares the supervised routes side by side.

Frequently Asked Questions
What testosterone level is actually low?
Most guidelines treat total testosterone below 300 ng/dL on two separate early-morning draws as the diagnostic threshold, with symptoms present. But the number alone decides very little. A man at 450 ng/dL with SHBG of 70 nmol/L can have less usable free testosterone than a man at 320 ng/dL with SHBG of 20. That is why free T and SHBG belong on the same panel as total.
Why is total testosterone alone misleading?
Roughly 98% of circulating testosterone is bound — mostly to SHBG, loosely to albumin — and bound hormone does not act on tissue. SHBG rises with age, thyroid excess, liver disease and some medications, so an older man can hold a normal total while his free fraction falls. Total testosterone also swings 20–30% across a single day and between days, so one draw is a snapshot of a moving number.
What should be ruled out before starting TRT?
Obstructive sleep apnea, obesity, thyroid dysfunction, prolactin excess, iron overload, chronic short sleep, heavy alcohol use, and medications such as opioids and long-term glucocorticoids. Each can lower testosterone or produce the same symptoms. Several are reversible, and reversing them can move levels enough that therapy is no longer the question.
Does TRT cause infertility?
External testosterone suppresses LH and FSH, which shuts down the signal for sperm production. Sperm counts fall substantially in most men within a few months, and while many recover after stopping, recovery can take a year or longer and is not guaranteed. Men who may want children should discuss sperm banking, HCG, or clomiphene alternatives before the first injection.
What does TRT cost per month?
The medication itself is the cheap part: generic injectable testosterone cypionate often runs $30–$100 a month. Physician-led programs that include consults, full panels and monitoring typically land between $150 and $400 a month all-in. Pellet protocols run $500–$1,000 per insertion three to four times a year. Compounded creams and branded oral forms sit in between.
How do I tell a real clinic from a TRT mill?
Look at what happens before the prescription. A real clinic orders a full panel, confirms low levels on two morning draws, works through reversible causes, raises fertility, and schedules follow-up labs at 6–12 weeks. A mill prescribes from one number in one visit and bills monthly. If nobody has asked about your sleep, your medications, or whether you want children, the diagnosis has not been made.
How long before TRT changes anything?
Libido and mood tend to shift within 3–6 weeks. Erectile function and energy often take up to 3–6 months. Body composition changes — more lean mass, less fat mass — build over 6–12 months and keep going for longer. Bone density changes take years. Judging the protocol at week four is judging it too early.
