Your starting point

Who is this for?

For men wanting oxygen-transport, hormone, kidney, thyroid and cholesterol information in one upper-arm collection.

The endurance connection

Why it matters.

Includes Hemoglobin, Hematocrit, Total and Free Testosterone and TSH, alongside broader health markers. PSA addresses prostate health separately from performance. This panel does not measure ferritin.

Know what you’re measuring

Every marker, explained.

Total Testosterone, Free Testosterone, Estradiol, SHBG, TSH, Total Cholesterol, LDL, HDL, Triglycerides, Creatinine, Hemoglobin, Hematocrit, PSA.

Counts follow the store. Profiles and calculated estimates are labeled separately from individual blood measurements.

MarkerWhat it can tell youWhy it matters for an athlete
Total TestosteroneHormonesTotal circulating testosterone, including protein-bound hormone.In men, persistently low morning levels with low libido or poor recovery warrant assessment. In women, a low result is not a standalone RED-S indicator. Endocrine Society: testosterone assessment ↗
Free TestosteroneHormonesThe unbound fraction of testosterone, interpreted with total testosterone and SHBG.Helps clarify a male hormone assessment when binding proteins affect the total result. There is no established female athletic-performance target. MedlinePlus: SHBG ↗
EstradiolHormonesAn estrogen involved in reproductive function and bone health.Low levels alongside missing periods raise concern about energy availability and bone stress injury risk. Cycle timing is essential. IOC: energy availability and athlete health ↗
SHBGHormonesA protein that binds sex hormones and affects their availability.Helps interpret total versus free testosterone; it is not a training-readiness score. MedlinePlus: SHBG ↗
TSHThyroidThe pituitary signal directing thyroid hormone production.Useful when fatigue comes with cold intolerance, unexplained weight changes or altered heart rate. Read with thyroid hormones. American Thyroid Association: thyroid tests ↗
Total CholesterolCholesterolThe overall amount of cholesterol in the blood.Helps assess long-term cardiovascular health. Fitness does not rule out lipid risk; abnormal levels often have no symptoms. MedlinePlus: cholesterol testing ↗
LDLCholesterolCholesterol carried in LDL particles.Helps assess long-term cardiovascular health. Fitness does not rule out lipid risk; abnormal levels often have no symptoms. MedlinePlus: cholesterol testing ↗
HDLCholesterolCholesterol carried in HDL particles.Helps assess long-term cardiovascular health. Fitness does not rule out lipid risk; abnormal levels often have no symptoms. MedlinePlus: cholesterol testing ↗
TriglyceridesCholesterolCirculating fats influenced by meals and metabolic health.Helps assess long-term cardiovascular health. Fitness does not rule out lipid risk; abnormal levels often have no symptoms. MedlinePlus: cholesterol testing ↗
CreatinineKidneyA muscle-derived waste product used to assess kidney function.Muscle mass, hard exercise, meat and creatine supplements can affect the result. MedlinePlus: creatinine ↗
HemoglobinOxygen transportThe oxygen-carrying protein in red blood cells.Low levels can contribute to breathlessness, fatigue and reduced endurance. This does not measure stored iron. MedlinePlus: hemoglobin ↗
HematocritOxygen transportThe proportion of blood volume occupied by red blood cells.Hydration and endurance-related plasma-volume changes affect it. Read alongside hemoglobin. MedlinePlus: hemoglobin ↗
PSAProstate healthA prostate protein used in individualized prostate assessment.Provides a separate health check, not a performance marker. Age, risk and symptoms guide interpretation. MedlinePlus: PSA and preparation ↗

Baseline · Build · Follow-up

Make testing part of your season.

This is a planning framework for a 12–16-week build. Your results and symptoms determine whether you need an earlier check.

01

Before the build

Collect during a recovered, representative week before increasing training. This gives you a comparison point.

02

During a 12–16-week build

If symptoms develop or previous results were borderline, arrange a targeted check with enough time to act before race week.

03

Between training blocks

Review the trend after recovery. Repeat the markers that answer your next question; a full panel is not automatically needed each time.

How often should you retest?

  • TestosteroneConfirm an unexpectedly low result on a separate fasting morning sample. Timing after a fueling or recovery change is individualized; there is no guaranteed number of weeks for recovery. Endocrine Society: testosterone assessment ↗
  • ThyroidUse symptoms and previous results to set follow-up. TSH commonly takes about 6–8 weeks to reassess after a thyroid medication dose change. This is not a universal lifestyle-retest schedule; TPO antibodies usually do not need serial monitoring. American Thyroid Association: thyroid tests ↗
  • Hemoglobin and broader health markersFrequency depends on previous results, symptoms and clinical risk. Low hemoglobin needs prompt assessment rather than waiting until the next training block. MedlinePlus: hemoglobin ↗

New or persistent symptoms deserve assessment between scheduled tests. There is no universal quarterly requirement for every marker.

A result worth comparing

Before you collect.

  • Follow your kit instructionsUse the collection and fasting instructions supplied with your kit. Drink water normally; do not arrive dehydrated or deliberately overhydrate.
  • Record your contextNote collection time, recent training, illness, sleep, medications and supplements. Do not stop prescribed medication without advice.
  • Choose a representative dayFor a resting comparison, avoid collecting immediately after a race, hard workout, overnight travel or while acutely ill. Wait until sleep and hydration are back to your usual pattern.
  • Use a consistent morning collectionMorning fasting samples are important when assessing low testosterone. Poor sleep and recent illness should be recorded.
  • Prepare for PSAAvoid ejaculation for 48 hours before collection. Tell your clinician about recent vigorous cycling, urinary symptoms or prostate procedures and follow their preparation advice.
  • Check biotin supplementsBiotin can interfere with thyroid assays. Ask the lab how long to pause your particular dose before collection; do not assume every supplement needs the same hold.
  • Record creatine and recent trainingCreatine supplements, a large meat meal and strenuous exercise can affect Creatinine. Ask about preparation rather than changing your routine without guidance.

Turn results into a next step.

Bring your results together with training load, fueling, symptoms and any supplements. Choose one clear action with your clinician or sports dietitian, then agree which markers to repeat and when.

Persistent fatigue, missing periods, recurrent bone stress injuries or unexpectedly abnormal results need clinical follow-up. A normal panel does not rule out RED-S or explain every change in performance.
