What is a 'normal' testosterone level?

Most labs report a reference range of roughly 264–916 ng/dL for total testosterone, but that range is built from a general population, not from men your age with your symptoms. Free testosterone — the fraction not bound to SHBG — often tells us more, which is why we measure total testosterone, free testosterone, SHBG, albumin, LH and FSH together rather than treating one number as the verdict.

What else has to be measured before starting therapy?

Estradiol, hematocrit, PSA where age-appropriate, thyroid panel, fasting glucose and HbA1c, lipids, and a comprehensive metabolic panel. Low testosterone is frequently downstream of sleep apnea, insulin resistance or thyroid dysfunction, and treating the number without checking those is how people end up on therapy they did not need.

How is testosterone therapy dosed?

Most protocols use subcutaneous or intramuscular testosterone cypionate, split into twice-weekly doses to keep levels steady rather than peaking and crashing. Dosing starts conservatively and is titrated against your follow-up labs and how you actually feel, not against a target number on a chart.

Does testosterone therapy affect fertility?

Yes. Exogenous testosterone suppresses LH and FSH and can significantly reduce sperm production. If fertility matters now or later, that has to be part of the first conversation — options include HCG or gonadorelin alongside therapy, or a different approach entirely.

What has to be monitored once I am on it?

Hematocrit, estradiol, PSA where applicable, lipids and your testosterone levels themselves, checked at the first follow-up and periodically after. Rising hematocrit is the most common reason to adjust a dose. A protocol that never re-tests is not medical care.

Testosterone is the hormone most men have heard of and the one most often reduced to a single number on a printout. This page covers what that number means, what sits underneath it, and what responsible therapy actually involves.

One value does not decide anything

Total testosterone measures everything circulating, including the large fraction bound to sex hormone-binding globulin and unavailable to your tissues. Free testosterone is what is actually doing the work. A man with a total of 500 ng/dL and high SHBG can be functionally deficient; a man at 350 ng/dL with low SHBG may feel fine.

That is why we never treat a single reading. The baseline panel reads the whole axis at once and puts it against your symptoms.

Total testosterone, free testosterone, SHBG and albumin — the bound and unbound picture.
LH and FSH — whether the signal is failing at the pituitary or at the testes.
Estradiol — the aromatized counterpart that determines bone, lipid and libido outcomes.
Thyroid, fasting glucose, HbA1c, lipids, hematocrit and inflammatory markers — the systems that suppress testosterone in the first place.

Low testosterone is often downstream of something else

Untreated sleep apnea, insulin resistance, chronic under-recovery and thyroid dysfunction all suppress the hypothalamic-pituitary-gonadal axis. Prescribing testosterone without checking those is how patients end up on lifelong therapy for a problem that had another cause.

Full detail on how we run that workup lives on hormone therapy in Chicago.

How therapy is dosed

Testosterone cypionate, subcutaneous or intramuscular, usually split into twice-weekly doses for steady levels.
Conservative starting dose, titrated against follow-up labs and symptoms rather than a target number.
Estradiol managed by dose adjustment first; aromatase inhibitors are a last resort, not a default.
HCG or gonadorelin considered when fertility or testicular function matters.
Peptides layered second, once the hormonal base is corrected — see the growth-hormone-axis pages in our library.

What monitoring requires

Hematocrit is the value most likely to force a change; rising red cell mass is the most common dose-limiting effect of testosterone therapy. Follow-up panels also track estradiol, PSA where age-appropriate, lipids and your testosterone levels themselves. Monitoring is built into the program, not sold as an add-on.

Medications and sourcing

Testosterone is a controlled substance and is prescribed only after a physician evaluation and a complete lab panel. Prescriptions are dispensed through licensed pharmacy partners and FDA-registered compounding pharmacies. Elevate Chicago is a direct-pay practice; your $100 application fee is credited toward your baseline labs.
