The Test, Don't Guess Health Loop starts with context and a broad biomarker baseline instead of ordering one or two tests in reaction to a single symptom. The practitioner combines the panel with symptoms, history, goals, and sex-specific interpretation to identify the most important gaps. Interventions are then selected against those measured needs, whether they involve lifestyle changes, supplements, or clinician-managed treatment. The process deliberately prioritizes rather than trying everything at once, making response easier to interpret. Follow-up testing and regular check-ins reveal whether the chosen action improved the target markers and how the person feels. Those results drive the next adjustment, turning a one-time blood draw into a repeatable cycle of measurement, targeted action, and reassessment.
Origin
Josh described this as the operating mentality behind Blokes and Joi: broad panels and patient questions are used to move care from reactive testing toward proactive, personalized decisions.
Core principles
- 01A broad baseline is more useful than isolated reactive tests
- 02Symptoms and biomarkers need to be interpreted together
- 03Interventions should address measured needs rather than assumptions
- 04Follow-up testing closes the loop
- 05Patients should understand and own their choices
How to run it
- 1
Build the baseline
Gather symptoms, goals, medical context, and a broad set of biomarkers. Avoid treating one isolated result as the whole picture.
Pro tip Use the same core panel on follow-up so meaningful changes are comparable.
Watch out Urgent symptoms require appropriate medical care rather than waiting for an optimization panel.
- 2
Interpret the whole picture
Review relationships among markers and match them to the person's circumstances. Apply relevant sex-specific ranges and clinical judgement rather than relying only on a generic normal flag.
Pro tip Ask which results explain the reported symptoms and which are incidental.
Watch out A laboratory value alone does not establish a diagnosis.
- 3
Rank measured gaps
Identify the few findings that matter most for risk, symptoms, or function. Sequence them instead of attempting every possible intervention simultaneously.
Pro tip Start with the issue most likely to improve several downstream outcomes.
Watch out Changing many variables together makes it difficult to identify what helped or harmed.
- 4
Act precisely
Choose lifestyle, nutritional, supplemental, or clinician-managed actions that correspond to the measured gap. Make the rationale for each action explicit.
Pro tip Record the target marker or symptom for every intervention.
Watch out Prescription drugs, hormones, and medication changes require qualified medical supervision.
- 5
Retest and adjust
Repeat relevant tests and review lived response on a regular cadence. Keep, change, or stop each intervention according to evidence and clinical guidance.
Pro tip Track symptoms alongside labs because either signal alone can be incomplete.
Watch out Do not increase a dose merely because progress is slower than expected.
In the wild
Josh reported low energy, absent sex drive, weight gain, high blood pressure, and testosterone in the low 200s, yet had been told he was normal. A more focused evaluation connected his symptoms and hormone level, after which clinician-managed treatment and broader habit changes were followed over time.
→ He reported early changes within about 30 days and a fuller improvement over roughly six months.
The guests describe using biomarker data and software to identify nutritional deficiencies, then selecting the most important needs when more issues appear than can fit into one supplement pack. The intervention is therefore tied to measured gaps rather than a generic supplement stack.
→ The person receives a smaller, prioritized set of supplements linked to current biomarker deficiencies.
Common mistakes
Testing one marker at a time
Reactive testing can produce a fragmented sequence of appointments without revealing the broader pattern.
Treating the reference range as the verdict
A generic normal label can miss the relationship between symptoms, age, sex, and the wider panel.
Changing everything at once
Stacking multiple therapies together obscures which intervention caused a benefit or side effect.
Is it for you?
Best for
It is best for people seeking a proactive view of health or trying to understand persistent symptoms with qualified clinical support.
Not ideal for
It is not a substitute for emergency care, diagnosis by a licensed clinician, or immediate treatment of an acute condition.
From the transcript
“what happens is you come in you have a symptom the doctor goes I'm going to test you for these two markers and then you…”
“if we're going to treat and if we're going to diagnose it's kind of this you know test don't guess mentality”
“we have a software that helps us drive it and then we look at the B markers and we say oh your DHE is low…”
