Understanding TRT

Start with your levels—not assumptions.

Testosterone plays a role in energy, sexual function, mood, muscle mass, and bone health. Levels can change with age, health conditions, medications, sleep, and other factors.

TRT is a prescription treatment for clinically confirmed testosterone deficiency. A licensed clinician uses your symptoms, health history, and lab results together to decide whether treatment is appropriate.

What low T can affect

One hormone. A wide range of possible symptoms.

Symptoms alone cannot diagnose low testosterone. Lab testing and clinical evaluation are essential.

01

Energy and focus

Low testosterone can be associated with fatigue, reduced motivation, and difficulty concentrating.

02

Strength and recovery

Changes in testosterone can affect muscle mass, physical performance, and recovery.

03

Sexual wellbeing

Low libido and changes in sexual function may be associated with testosterone deficiency.

04

Mood and body composition

Mood changes, increased body fat, and reduced wellbeing can have many causes, including low testosterone.

Individual results vary. TRT is only prescribed when a clinician determines it is medically appropriate.

Testosterone therapy may impair fertility and is not appropriate for everyone.

Questions, answered

Start my assessment
What are the symptoms of low testosterone?

Possible symptoms include reduced sex drive, fatigue, mood changes, difficulty concentrating, reduced muscle mass, increased body fat, and changes in sexual function. These symptoms can have many causes, so testing and clinical evaluation are important.

What does the $49 assessment include?

It includes an initial lab panel and an online consultation with a licensed clinician. If you are approved and medication is prescribed, you’ll be charged an additional $149. No action is needed from you; our care team will process the charge after approval.

Does purchasing the assessment guarantee a prescription?

No. A prescription is never guaranteed. Your clinician will determine whether treatment is medically appropriate after reviewing your lab results, symptoms, health history, and any additional information required in your state. If approved and prescribed, you’ll be charged an additional $149.

What treatments are available?

If you are eligible, your clinician will discuss appropriate treatment options, dosing, monitoring, potential benefits, and risks. The exact treatment depends on your individual clinical evaluation and state availability.

How quickly will I notice results?

Response times vary by person and by symptom. Your clinician will explain what to expect and how your progress and laboratory values should be monitored. Do not change a prescribed dose without medical guidance.

Can TRT affect fertility?

Yes. Testosterone therapy can reduce sperm production and may impair fertility. Tell your clinician if you are trying to conceive now or may want children in the future.

Do I need insurance?

No. The starter assessment is a cash-pay service. Your clinician will explain any additional costs before you choose to continue with testing or treatment beyond what is included.

Where is the TRT assessment available?

Availability depends on clinician licensing and state requirements. The online program is currently unavailable in Alaska, Mississippi, and New Jersey.
