The athlete test menu
Six panels, each chosen for what actually moves when you train. Pick your baseline, test, then train to the data.
Comprehensive Liver Function
20+ markers
Includes ferritin and iron, the markers behind unexplained fatigue and flat performance, since endurance training quietly depletes iron stores long before you feel it.
Comprehensive Female Hormone
6 markers
Heavy training loads can suppress progesterone and push cortisol up, the hormonal signature behind RED-S and stalled recovery in female endurance athletes.
Male Hormone
7 markers
Chronic overtraining drops free testosterone and raises SHBG, an early flag that your recovery isn't keeping pace with your mileage.
Thyroid
4 markers
Thyroid output sets your metabolic rate and resting heart rate, so a sluggish TSH can explain fatigue and flat performance that training tweaks won't fix.
Cortisol
4 markers
A rising cortisol to DHEA-S ratio is one of the cleanest signals that you've crossed from productive training stress into burnout.
Vitamin D & Metabolic
7 markers
Low vitamin D blunts power and bone resilience, while insulin sensitivity governs how well you fuel long efforts, the two levers behind both performance and durability.
