What is testosterone replacement therapy?
Testosterone replacement therapy (TRT) restores testosterone to a healthy, optimal range using bio-identical testosterone — prescribed and monitored by Teresa Powell, FNP-BC. Rather than a standard dose, your protocol is built around your own comprehensive lab work, symptoms, and goals.
Signs of low testosterone
Low testosterone is common, measurable, and treatable — and it affects far more than the gym. Common signs include:
- Fatigue — low energy that doesn't improve with rest
- Low libido — reduced sex drive or performance
- Muscle loss — harder time building or maintaining muscle
- Mood changes — irritability, low motivation, or brain fog
- Poor sleep — trouble falling or staying asleep
- Weight gain — especially around the midsection
TRT vs. over-the-counter boosters
"Testosterone boosters" sold over the counter aren't regulated the same way and don't actually contain testosterone. Physician-supervised TRT uses real, bio-identical testosterone, dosed to your labs and monitored for safety.
| OTC "boosters" | Physician-supervised TRT | |
|---|---|---|
| What it contains | Herbal/vitamin blends, no real testosterone | Bio-identical testosterone |
| Dosing | Generic, one-size-fits-all | Personalized to your lab results |
| Monitoring | None | Regular bloodwork — testosterone, PSA, red blood cell count |
| Results | Unproven, inconsistent | Measurable, lab-tracked improvement |
TRT delivery methods
Your protocol is tailored to your preferences and lifestyle — there's no single right delivery method for everyone.
- Injections — a common, cost-effective option, typically self-administered weekly
- Pellet implants — long-lasting, consistent delivery over several months via a brief in-office procedure
- Topical gels & creams — daily at-home application with steady absorption
Who is a candidate?
Men experiencing symptoms of low testosterone — fatigue, low libido, muscle loss, mood changes, or poor sleep — are candidates for a comprehensive hormone panel and consultation. Diagnosis is based on both your symptoms and your bloodwork, not symptoms alone.
Benefits of TRT
When testosterone is restored to an optimal range, most men notice improvements across several areas of daily life:
- Energy & drive — more consistent energy throughout the day
- Muscle strength — easier muscle building and faster recovery
- Mood & focus — more stable mood and sharper concentration
- Bone density — long-term support for bone health
What this treatment offers
Things to consider
- Regular monitoring of red blood cell counts, PSA, and hormone levels is required throughout treatment.
- TRT can affect fertility — this is discussed with you before starting if it's a concern.
- Not recommended for men with untreated prostate or breast cancer.
- Lifestyle factors like sleep, exercise, and stress also affect testosterone levels.

Frequently asked questions
How do I know if I have low testosterone?+
A comprehensive hormone panel measures your testosterone levels alongside a review of your symptoms — fatigue, low libido, muscle loss, mood changes, or poor sleep. Diagnosis is based on both your bloodwork and your symptoms.
What does TRT monitoring involve?+
Regular bloodwork tracks your testosterone levels, PSA, and red blood cell count to keep your protocol safe and effective, with follow-up appointments to adjust your dose as needed.
What delivery methods are available, and which is best for me?+
TRT can be delivered via injections, pellet implants, or topical gels/creams. The best option depends on your lifestyle and preferences — Teresa will help you choose.
Will TRT affect my fertility?+
TRT can suppress natural sperm production in some men. If fertility is a concern, this is discussed and planned for before starting treatment.
How soon will I notice results?+
Many men notice improvements in energy and mood within a few weeks, with changes in muscle strength and body composition typically building over a few months as your levels stabilize.
Is TRT safe long-term?+
TRT is generally safe when prescribed and monitored by a qualified provider. Regular lab monitoring — testosterone, PSA, and red blood cell count — helps catch and manage any risks early.
