The athlete test menu
Two complete endurance bundles plus six targeted panels, each chosen around the markers that matter for training, recovery, and long-term performance.
Female Endurance Bundle
35 markers across 3 tests
A comprehensive view of liver function, thyroid health, hormones, iron status, blood sugar, cholesterol, and recovery markers for female endurance athletes.
Male Endurance Bundle
36 markers across 3 tests
A comprehensive view of liver function, thyroid health, hormones, iron status, blood sugar, cholesterol, and recovery markers for male endurance athletes.
Comprehensive Liver Function Panel
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 Panel
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 Wellness Panel
12 markers
Chronic overtraining drops free testosterone and raises SHBG, an early flag that your recovery isn't keeping pace with your mileage.
Thyroid Panel
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 Panel
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 Panel
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.
