Cortisol AM on TRT
What the number means, why it moves on a protocol, and how it sits with related markers.
What it is
Morning cortisol is the stress hormone at its daily peak. It shows whether recovery is happening or the body is running on fumes.
The range
How to read the lab range
Morning range roughly 6 to 23 µg/dL (170 to 630 nmol/L); it is only meaningful drawn before 9 am. A low morning result with fatigue is one to raise with your doctor.
Why it moves on a protocol
- Sleep debt, overtraining, hard dieting.
- Corticosteroid medication suppresses it.
- Time of draw, which changes it more than anything.

Does testosterone lower cortisol?
A little. A high morning cortisol on TRT is more often sleep or training load than the protocol.
