The Problem With 'Normal'
Every day, men walk out of their doctor's office with a testosterone result flagged as 'normal' — and every day, those same men still feel exhausted, foggy, low-libido, and unmotivated.
The issue isn't the test. It's what we call normal.
Reference Ranges Are Not Optimal Ranges
Standard testosterone reference ranges — typically 300–1000 ng/dL — were established by averaging large populations, including sedentary individuals, men with undiagnosed metabolic dysfunction, and men decades older than you.
A 340 ng/dL result will show up as 'within range.' But for a 42-year-old who used to have energy, drive, and mental clarity, 340 is not a target. It's a floor.
What We Actually Look For
At PracticeRx, we evaluate testosterone within the context of your full hormonal picture:
- Total testosterone — the number your PCP runs
- Free testosterone — the fraction actually bioavailable to your cells
- SHBG (Sex Hormone Binding Globulin) — a protein that binds testosterone and renders it inactive
- LH and FSH — pituitary signals that reveal whether the problem is upstream
- Estradiol — elevated in men with excess adipose tissue, and a driver of many 'low T' symptoms
- Prolactin — elevated levels suppress testosterone production
You can have a 'normal' total testosterone and still have critically low free testosterone because SHBG is elevated. Your PCP likely didn't run SHBG.
Symptoms Are Data
Lab values tell part of the story. Symptoms tell the rest. If you're experiencing:
- Persistent fatigue despite adequate sleep
- Reduced motivation or drive
- Difficulty building or maintaining muscle
- Low libido or sexual dysfunction
- Mood changes, irritability, or depression
- Brain fog or poor concentration
...those are clinically relevant data points — not things to 'push through.'
What Optimization Actually Looks Like
Testosterone replacement therapy (TRT), when properly administered, is one of the most evidence-backed interventions in men's health. But it requires precision — the right delivery method, the right dosing, and ongoing monitoring of a full hormonal panel.
We don't chase a number. We chase a feeling — backed by data.
If you've been told your labs are fine and you still don't feel fine, that's not a coincidence. That's a gap in your care.
PracticeRx offers comprehensive hormone panels and TRT management for men nationwide via telemedicine and in-person in Scottsdale, AZ.
