Testosterone falls with age, varies by the hour, and dips with poor sleep, illness, and weight gain, which is why a single number is nearly meaningless. The Endocrine Society's guideline is built on that fact: diagnose hypogonadism only in men with symptoms and signs consistent with deficiency AND unequivocally, consistently low levels, measured as fasting morning total testosterone and confirmed with a second morning measurement. Borderline result, or a condition that shifts binding proteins? The guideline calls for a free testosterone measurement on top. Symptoms alone do not make the diagnosis either, because fatigue, low sex drive, and low mood are also depression, sleep apnea, and life.
Both major labs publish consumer prices for a total testosterone test at $69 (Quest adds a $6 physician-service fee), drawn at their regular locations. If you want to walk in with data, book it as a fasting morning draw, before 10 a.m., and remember the rule: a low result earns a second morning test, not a prescription. A primary care clinician or an endocrinologist can order the same labs, bill insurance, and, more importantly, look for the cause, because low testosterone is often the symptom of something else: obesity, sleep apnea, diabetes, medications, or a pituitary problem that deserves its own attention.
The cardiovascular question got its real answer in 2023. The TRAVERSE trial randomized 5,246 men aged 45 to 80, all with existing heart disease or high risk plus confirmed low testosterone and symptoms, to testosterone gel or placebo. Major cardiac events were statistically no more common with testosterone: 7.0 percent versus 7.3 percent. That is genuinely reassuring for men who meet criteria. The same trial also logged more atrial fibrillation, acute kidney injury, and pulmonary embolism in the testosterone group, which is why legitimate treatment comes with monitoring, not refills alone.
Your primary care doctor or a community health center can check the underlying cause (blood pressure, diabetes, low testosterone) on a sliding scale, and often prescribes the same medication a paid service sells at a markup. Our directory of free and charitable clinics lists verified centers by state. A same-day telehealth visit is self-pay and is not billed to Medicaid, so the clinic visit usually costs less if you have coverage. If you want a telehealth visit sooner:

Direct-to-consumer testosterone is a big business built inside the gap between a low lab and a real diagnosis. A published review of 223 online men's health clinics found 88 percent offering testosterone therapy, with urologists as the primary clinician at just 10 percent, and concluded there is significant heterogeneity and misinformation in what the public encounters. The economics deserve the same daylight: a peer-reviewed cost comparison put twelve months of injectable testosterone at $1,586 to $4,200 through telemedicine platforms versus $134 to $1,333 at a tertiary medical center, depending on insurance. Some platforms run guideline-consistent evaluations; the price of convenience is still several multiples of standard care.
The read-the-clinic checklist, built from the diagnosis rules above: a legitimate prescriber requires two morning tests before treating, asks about and works up other causes, discusses fertility (testosterone therapy suppresses sperm production), monitors blood counts and levels on a schedule, and will tell some men no. A funnel diagnoses everyone, treats from one afternoon test, and sells the monitoring as an upsell.
Start with a morning draw and a clinician who will treat the whole picture. Our provider directory lists Black internists, endocrinologists, and urologists by city, and if cost is the constraint, our directory of free and charitable clinics lists community health centers that do lab workups on a sliding scale.

Frequently asked questions
What testosterone level is considered low? ▼
Most labs and trials use a total testosterone below roughly 300 ng/dL as the screening threshold; the TRAVERSE trial enrolled men below that line. But the number only counts when it is a fasting morning draw, confirmed by a second one, in a man with real symptoms. Late-day tests read low in healthy men.
Is TRT safe for the heart? ▼
In the TRAVERSE trial of 5,246 higher-risk men who genuinely met criteria, testosterone therapy did not increase major cardiac events versus placebo (7.0 versus 7.3 percent). The trial did find more atrial fibrillation, acute kidney injury, and pulmonary embolism with testosterone, so treatment belongs alongside monitoring, not instead of it.
Why is my energy low if my testosterone is normal? ▼
Because fatigue is the least specific symptom in medicine. Sleep apnea, depression, thyroid problems, anemia, and plain sleep debt all present the same way, and several of them hit Black men earlier and harder than average. That differential is exactly why the workup belongs with a clinician rather than a checkout page.
