Frequently asked questions
How does Nx Vitality + differ from testosterone alone?
This plan pairs testosterone cypionate injections with oral anastrozole. The additional medicine needs its own clinical rationale and monitoring; the combination is not interchangeable with a testosterone-only plan.
Does everyone on TRT need anastrozole?
No. A clinician considers symptoms, hormone results, and alternatives before deciding whether estrogen management is needed. Anastrozole use in male hormone care is off-label.
Does the three-month plan set my dose or schedule?
No. Your clinician and pharmacy provide separate instructions for each medicine. Plan length does not determine dose, frequency, or when follow-up testing is needed.
Will TRT improve my energy?
Some people report improvement, but fatigue has many causes and clinical trials have not shown consistent benefits on every energy measure. The evaluation should address those other causes too.
Can I use TRT while trying to conceive?
Testosterone can suppress sperm production. Tell your clinician about current or future fertility plans before starting; a different approach may be needed.
Does a longer plan mean a higher dose?
No. Plan length and prescribed dose are separate decisions. Your clinician determines the medication and follow-up based on your clinical findings.
Do I need blood tests before or during TRT?
Diagnosis usually combines symptoms with repeated morning testosterone measurements. Your clinician decides which baseline and follow-up tests are needed. Bring existing results with their dates and collection times; do not order a panel solely from the product name.
How do I choose between cream and injections?
Discuss your routine, comfort with injections, skin-contact precautions, previous treatment, and follow-up needs. Each preparation has its own instructions and monitoring; a higher price or longer plan does not make one the right choice for everyone.
How do I store and handle my injections?
Use the storage temperature, usable-life date, and handling instructions supplied by your dispensing pharmacy. Concentrations and preparations vary. Ask for clarification before injecting if the label or syringe measurement is unclear.
Safety information & side effects
Both medicines need an individual review and ongoing monitoring.
- Treatment can suppress sperm production and raise red blood cell levels and blood pressure.
- Acne, swelling, breast symptoms, and changes in sleep or urinary symptoms should be discussed with your clinician.
- Cardiovascular trial results do not mean treatment has no risk; the choice of formulation and your medical history matter.
- Compounded medications are not FDA-approved. The clinician and pharmacy must determine whether a compounded preparation is appropriate for your individual needs.
- Anastrozole can reduce bone mineral density and increase cholesterol. Discuss bone health, joint symptoms, and the monitoring appropriate for you.
- Do not adjust either medicine from an isolated hormone result. Excessive estrogen suppression can create its own problems.

A closer look
Understand your options.
Start with what this treatment is, why it may be considered, and what to discuss with your clinician.
Sexual desire & wellbeing
Discuss changes in libido and daily wellbeing. Testosterone is not a general erectile-dysfunction treatment.
Labs that guide your care
Follow-up checks help your clinician assess response, blood counts, and whether treatment remains appropriate.
How it works
Two medicines. One individual hormone-care plan.
Testosterone replaces a confirmed deficiency. Anastrozole reduces conversion to estrogen and requires a separate clinical rationale; it is not an automatic addition to every testosterone plan. Its use for male hormone management is off-label.
Explore the evidenceResearch over time
How testosterone research unfolds over time.
From early monitoring to longer-term outcomes: checkpoints from testosterone-gel studies and labeling.
The 1.62% gel label calls for a blood-level check around day 14, then day 28. This is a monitoring milestone, not a deadline for feeling different.
Testosterone gel 1.62% · Dosing and monitoring label ↗ (opens in a new tab)In a 227-man trial, sexual-function scores improved from baseline by day 30 with testosterone gel or patches. Both groups received testosterone; there was no placebo group.
Wang et al. · Testosterone gel trial, 2000 ↗ (opens in a new tab)The same trial found gains in lean mass and leg strength by day 90. It studied 1% gel at 50–100 mg daily against a testosterone patch, not compounded cream or injections.
Wang et al. · Testosterone gel trial, 2000 ↗ (opens in a new tab)Among men with anemia and low testosterone in TRAVERSE, 41% with six-month measurements had anemia corrected with 1.62% gel, versus 27.5% with placebo. This was a specific clinical subgroup.
TRAVERSE anemia study · JAMA Network Open, 2023 ↗ (opens in a new tab)In the Testosterone Trials, men 65 and older with low levels had modest sexual-function benefits with 1% gel versus placebo over one year. The main vitality measure did not significantly improve.
Testosterone Trials · NEJM, 2016 ↗ (opens in a new tab)
These checkpoints combine different studies and gel labeling, not one person's expected journey. Findings do not establish the same timing or results for compounded cream or cypionate injections. Your clinician sets monitoring and reviews benefits, side effects, and whether to continue.
Personal care starts with context
Is it right for you?
TRT starts with a diagnosis, not a goal testosterone number.
- Symptoms together with consistently low testosterone measurements.
- Fertility goals, sleep apnea, prostate history, and cardiovascular or clotting conditions.
- Your ability to complete recommended blood tests and follow-up.
The evidence behind the conversation
Research & guidance.
Know what was studied, who took part, and how it relates to this option. Study findings are not a prediction of your results.
01Testosterone cypionate · Prescribing information
Describes replacement treatment for diagnosed testosterone deficiency and monitoring for blood pressure, blood counts, and other adverse effects.
- Treatment studied / guidance scope
- Labeled testosterone cypionate injection.
- Who it applies to
- Men with an indicated testosterone-deficiency condition.
- Timeframe
- Prescribing information; not a combination trial
- Comparison
- No clinical comparator
What this means for this optionThis label does not establish outcomes for a testosterone/anastrozole combination or replace the instructions for your own prescription.
Read the source (opens in a new tab)02Anastrozole · Prescribing information
Describes aromatase inhibition and precautions including reduced bone mineral density and increased cholesterol.
- Treatment studied / guidance scope
- Labeled oral anastrozole tablets.
- Who it applies to
- Postmenopausal women treated for labeled breast-cancer indications.
- Timeframe
- Prescribing information; not a male hormone-care trial
- Comparison
- Not evidence for this combination
What this means for this optionUse for male estrogen management is off-label. The labeled cancer regimen is not a dosing guide for this care plan.
Read the source (opens in a new tab)03AUA/ASRM guidance · Male infertility
Selected men with infertility and low testosterone may be considered for medicines that stimulate their own hormone production. Evidence is limited and treatment is individualized.
- Treatment studied / guidance scope
- Selective estrogen receptor modulators such as clomiphene, aromatase inhibitors, and other selected therapies.
- Who it applies to
- Men evaluated for infertility; suitability depends on the underlying cause.
- Timeframe
- Clinical guideline, not a fixed-duration trial
- Comparison
- Alternatives depend on diagnosis
What this means for this optionClomiphene and anastrozole use in men is off-label. This guidance does not support routine estrogen suppression for everyone on TRT. Improved laboratory measurements do not guarantee pregnancy or a live birth.
