New to hormone
therapy?
A plain-English guide to TRT, BHRT, and the hormones that shape how men feel, perform, and age. Reviewed by our medical team.
"Replacing the hormones we lose with age — testosterone, thyroid, DHEA, estradiol — back to physiologic levels can meaningfully improve health and quality of life."
The truth about hormones in men
Menopause in women is widely discussed and well-studied. Its male counterpart — sometimes called andropause — is far less understood, despite producing similar experiences: fatigue, low mood, reduced drive, aches, weight gain, and cognitive fog. It typically begins in a man's 40s as testosterone and other hormones gradually decline.
Public conversation about testosterone is often shaped by athletic abuse stories, which has created the impression that all testosterone is dangerous. Medically supervised replacement at physiologic doses is a fundamentally different therapy from supraphysiologic athletic misuse.
Bioidentical testosterone therapy, prescribed by a licensed provider after labs and a clinical evaluation, has a long-established safety record in appropriately selected patients. It is not a fountain of youth — but it is, for many men, a way to feel like themselves again.
What HRT can support
Reported benefits.
Individual results vary. Benefits depend on baseline labs, adherence, lifestyle, and clinical response.
Energy & stamina
Many patients report higher daily energy and improved exercise tolerance within the first weeks.
Lean muscle & strength
Optimized testosterone supports protein synthesis, muscle tone, and recovery.
Mood & focus
Hormones influence cognition, motivation, and mood regulation.
Cardiometabolic health
Healthy hormone levels are associated with favorable lipids, body composition, and insulin sensitivity.
Libido & sexual function
Restoration of physiologic levels often improves libido and erectile function.
Bone density
Testosterone — via conversion to estradiol — plays a key role in maintaining bone mass.
The hormones
Which hormones change with age.
Testosterone
The primary male androgen. Supports libido, lean muscle, bone density, energy, mood, and red blood cell production. Levels typically decline ~1% per year after age 30. Replacement aims for physiologic levels seen in healthy young adults — not supraphysiologic doses.
Estradiol (E2)
A byproduct of testosterone via aromatization. Essential — not optional — for bone, brain, cardiovascular, and sexual health in men. Indiscriminate use of aromatase inhibitors can be harmful; estradiol is managed only when levels and symptoms warrant it.
DHEA
A precursor hormone produced by the adrenal glands. Supports immune function, stress response, and conversion to other sex hormones. Levels decline steadily with age and may be assessed alongside testosterone.
Thyroid (TSH, Free T3/T4)
Regulates metabolism, body temperature, energy, and cognition. Untreated thyroid imbalance can mimic or worsen low-T symptoms, which is why we screen thyroid alongside hormones.
Lab interpretation
Why "normal" isn't always optimal.
Many men are told their testosterone is "normal" because it falls inside a wide reference range built from population averages — averages that include men who are themselves deficient. A result at the low end of that range can be clinically inadequate, especially when symptoms are present.
Our providers interpret labs in the full clinical context: total and free testosterone, SHBG, estradiol, thyroid markers, CBC, metabolic panel, and PSA — alongside your symptoms and history. Treatment, if appropriate, targets a healthy physiologic range, not a number on a marketing slide.
Delivery methods
Injection or cream?
Subcutaneous injection
A small insulin-style needle delivers testosterone into the subcutaneous fat layer (commonly the abdomen or thigh). Typically dosed weekly or split into more frequent micro-doses. Predictable absorption, easy to titrate.
Topical cream
Applied to the skin once or twice daily. Needle-free and convenient, with steady daily levels. Requires care to avoid transference to partners or children and may have variable absorption between patients.
Your provider will recommend a route based on your labs, lifestyle, and preference.
Safety
Side effects & considerations.
Like any medication, hormone therapy carries potential side effects. Commonly monitored items include changes in hematocrit (red blood cell concentration), estradiol balance, blood pressure, lipid profile, and PSA. Acne, fluid retention, mood changes, and injection-site reactions can occur.
Therapy is not appropriate for everyone. Contraindications include active or recent prostate or breast cancer, untreated severe sleep apnea, uncontrolled heart failure, very high hematocrit, and a desire for fertility in the near term (TRT typically suppresses sperm production).
Routine follow-up labs and clinical check-ins are part of every protocol — that's how therapy stays both effective and safe.
Report any suspected adverse reaction to your provider and to the FDA at fda.gov/medwatch or 1-800-FDA-1088.
FAQ
Frequently asked questions.
What is HRT?+
HRT — hormone replacement therapy — is the clinical use of hormones (such as testosterone or thyroid) to restore levels that have declined due to age or medical conditions, under physician supervision.
What is TRT?+
TRT — testosterone replacement therapy — is HRT focused specifically on restoring testosterone to a healthy physiologic range in men with clinically low levels and associated symptoms.
What are bioidentical hormones?+
Bioidentical hormones are structurally identical to the hormones your body produces naturally. They are FDA-regulated when prescribed as approved products and dispensed by licensed U.S. pharmacies.
How long until I notice results?+
Many patients report energy and mood changes within 2–4 weeks. Sexual function improvements often appear within 3–6 weeks. Changes in body composition and strength typically develop over 12–24 weeks with consistent training and nutrition.
Is TRT safe?+
When prescribed and monitored by a licensed provider with periodic labs, TRT has a well-established safety profile in appropriately selected patients. Like any medication, it has potential risks and is not appropriate for everyone.
Do I have to stay on it?+
Therapy is effective for as long as it is taken. If you stop, your levels — and symptoms — generally return to your pre-treatment baseline. This decision is made with your provider.
What about prostate cancer?+
Current evidence does not show that testosterone therapy causes prostate cancer. Active prostate cancer remains a contraindication, which is why PSA is checked at baseline and during therapy.
