A calculated wellness ratio pairing free testosterone with cortisol.
What it is
Some performance panels report testosterone:cortisol style ratios. They are not standardised diagnostic indices in routine NHS endocrinology.
Why it matters
Interesting for trend watching; easy to over-interpret after poor sleep or a hard block.
This guide is educational only and cannot diagnose you. Discuss results, especially anything outside your laboratory’s reference interval, or that does not match how you feel, with a GP or other appropriately qualified clinician.
How it affects the body
Anabolic and stress-hormone signals interact across training and recovery cycles.
For athletes
Use as a conversation starter with a qualified clinician or coach, not a reason to self-medicate.
