## What is TRT?

Testosterone Replacement Therapy (TRT) is a medically supervised treatment that restores testosterone levels in men diagnosed with hypogonadism — a condition where the body does not produce enough testosterone on its own. TRT is prescribed by licensed physicians after confirming low testosterone through blood work and clinical evaluation.

## Why Do People Use TRT?

Men seek TRT when they experience persistent symptoms of low testosterone, including:

- **Chronic fatigue** — feeling tired despite adequate sleep
- **Low libido** — reduced sexual desire or erectile difficulties
- **Loss of muscle mass** — difficulty building or maintaining muscle
- **Increased body fat** — especially around the midsection
- **Brain fog** — difficulty concentrating, poor memory
- **Mood changes** — irritability, depression, or lack of motivation
- **Reduced bone density** — increased fracture risk over time

These symptoms typically develop gradually, often after age 30 when testosterone naturally declines at approximately 1% per year.

## Common Misconceptions

| Misconception | Reality |
|---|---|
| TRT is the same as anabolic steroid abuse | TRT restores testosterone to normal physiological levels under medical supervision; steroid abuse uses supraphysiological doses without oversight |
| Only older men need TRT | Hypogonadism can affect men at any age, though it becomes more common after 40 |
| TRT is a quick fix | Benefits develop gradually over 3-12 months with consistent treatment |
| TRT is dangerous | When properly monitored with regular blood work, TRT has a well-established safety profile |
| You can buy testosterone without a prescription | Testosterone is a Schedule III controlled substance in the US and legally requires a prescription |

## TRT vs. Natural Testosterone Support

Natural approaches — such as improving sleep, exercise, diet, and stress management — can modestly support testosterone levels. However, these methods cannot correct clinically diagnosed hypogonadism. When total testosterone is consistently below 300 ng/dL with symptoms present, medical intervention through TRT is the evidence-based approach.

## When is TRT Medically Advised?

TRT is typically recommended when:

1. **Blood work confirms low testosterone** — total testosterone below 300 ng/dL on at least two morning tests
2. **Symptoms are present** — fatigue, low libido, mood changes, or other clinical signs
3. **Other causes have been ruled out** — thyroid disorders, sleep apnea, medication effects, or pituitary conditions
4. **No absolute contraindications exist** — such as active prostate cancer, untreated severe sleep apnea, or uncontrolled heart failure

## How TRT is Accessed Today

Modern TRT is increasingly accessed through licensed telehealth clinics that provide:

- At-home or local lab testing
- Virtual physician consultations
- Prescription medications shipped directly to the patient
- Ongoing monitoring and dosage adjustments

This telehealth model has made TRT accessible to men nationwide, including those in rural areas without nearby endocrinologists.
