Your starting point
Who is this for?
For men investigating reduced libido or hormone concerns while also checking longer-term metabolic health.
The endurance connection
Why it matters.
Total and Free Testosterone, SHBG and LH help frame a hormone assessment. The remaining results add metabolic context. This standalone panel is different from the Male Hormone Panel inside the endurance bundle.
IOC: energy availability and athlete health ↗Know what you’re measuring
Every marker, explained.
Total Testosterone, Free Testosterone, PSA, Estradiol, SHBG, LH, Cholesterol Profile, Insulin Resistance, Inflammation, Average Blood Sugars, GGT, Visceral Fat Estimate.
Counts follow the store. Profiles and calculated estimates are labeled separately from individual blood measurements.
| Marker | What it can tell you | Why it matters for an athlete |
|---|---|---|
| Total TestosteroneHormones | Total 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 TestosteroneHormones | The 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 ↗ |
| PSAProstate health | A 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 ↗ |
| EstradiolHormones | An 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 ↗ |
| SHBGHormones | A protein that binds sex hormones and affects their availability. | Helps interpret total versus free testosterone; it is not a training-readiness score. MedlinePlus: SHBG ↗ |
| LHHormones | Pituitary signaling that stimulates testosterone production in men. | With low testosterone, LH helps a clinician investigate the source of the change, including possible suppression of reproductive signaling. Endocrine Society: testosterone assessment ↗ |
| Cholesterol ProfileCholesterol | A grouped report of cholesterol and lipid measures. | Supports long-term cardiovascular assessment, even when training and performance feel good. MedlinePlus: cholesterol testing ↗ |
| Insulin ResistanceMetabolic health | Reporting related to how effectively the body responds to insulin. | Metabolic context, not a test of carbohydrate availability for your next session. NIDDK: HbA1c and the three-month view ↗ |
| InflammationInflammation | An inflammatory signal that requires context about illness and recent exercise. | A hard session or infection can change the result. It cannot identify the cause or diagnose overtraining by itself. IOC: energy availability and athlete health ↗ |
| Average Blood SugarsBlood sugar | Average blood sugar over approximately three months. | Tracks longer-term metabolic health, not race fueling. Iron deficiency and altered red-cell turnover can affect results. NIDDK: HbA1c and the three-month view ↗ |
| GGTLiver | An enzyme that contributes to liver and bile-duct assessment. | Alcohol and some medicines can affect it. It is not a direct overtraining marker. MedlinePlus: liver tests ↗ |
| Visceral Fat EstimateCalculated estimate | An estimate related to fat around internal organs, not a direct imaging measurement. | Adds metabolic-health context. It should not become a weight-loss target during a demanding build. IOC: energy availability and athlete health ↗ |
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 ↗
- Average blood sugarAllow roughly three months to assess a longer-term HbA1c trend. It cannot show whether yesterday’s fueling was enough. NIDDK: HbA1c and the three-month view ↗
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.
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.
