    Hone Health vs Function Health: What Each Is Actually Built to Do

    John is an operator with two decades of experience building and leading performance-driven teams. He is not a physician. Performance Protocol exists because he needed a system for training, recovery, hormones, and cognitive output that was built on data rather than marketing — and could not find one.

    The most common mistake when comparing these two is treating them as competitors. They are not the same category of product. Choosing between them is not like choosing between two gyms — it is more like choosing between a gym and a sports medicine clinic. Both involve your health; they address different problems.

    What each service is

    Function Health is a lab testing membership. You pay an annual fee, get a blood draw twice a year, and receive results for 100+ biomarkers across cardiovascular, metabolic, hormonal, thyroid, immune, nutritional and inflammatory categories. Function does not prescribe anything, does not offer clinical consultations as part of the membership, and does not follow up on your results. It gives you data.

    Hone Health is a telehealth men's health clinic. The process: order a home testing kit focused on hormone and metabolic markers, a physician reviews your results, and if you are a candidate for TRT or other hormonal optimisation, Hone manages the prescription and ongoing monitoring. It gives you a clinical outcome.

    When to use Function Health

    You want a complete picture of where your body stands across every major system — not just hormones. The five longevity biomarkers that matter most (ApoB, fasting insulin, HbA1c, hs-CRP, testosterone) are all in the standard Function panel alongside 80+ others that give you a broader baseline. If you have a physician who can act on the results, Function is the most efficient first-pass data source available.

    Use Function if you want to know everything, then decide what to act on.

    When to use Hone Health

    You suspect low testosterone and want a guided, physician-supervised pathway from test to treatment. Hone's process is designed specifically for this: the test identifies the problem, the physician interprets it in context, and the clinic manages the treatment. You do not have to find a separate physician, interpret lab values yourself, or navigate a traditional healthcare system that frequently under-treats hormone issues.

    Use Hone if you want to evaluate and potentially treat testosterone specifically, with clinical support throughout.

    The honest trade-offs

    Function's limitation: data without action. 100 biomarkers is overwhelming without a clinician to prioritise what to address. If your only output is a dashboard you look at once, you overpaid.

    Hone's limitation: narrow scope. Hone's testing is optimised for hormone evaluation, not comprehensive health monitoring. You will not get ApoB, fasting insulin, or thyroid depth from their initial panel.

    The practical answer for most men: use both. Function Health for the annual comprehensive baseline; Hone (or Marek Health, or Maximus) for the TRT evaluation and management. They complement each other rather than compete.

    Frequently asked questions

    What is the difference between Hone Health and Function Health?+
    Function Health is a lab testing membership that runs 100+ biomarkers twice a year. It provides data, not treatment. Hone Health is a telehealth clinic that starts with hormone testing and then offers physician-supervised TRT if indicated. They serve different purposes: Function Health for comprehensive annual baselines, Hone for a guided testosterone evaluation and treatment pathway.
    Is Hone Health or Function Health better for testosterone testing?+
    Hone Health is the better choice if your goal is testosterone evaluation and potential TRT — the process includes a physician review and prescription pathway. Function Health tests testosterone as part of its broader panel but does not provide clinical follow-up or prescriptions. For a comprehensive baseline that includes testosterone alongside 100+ other markers, Function Health is more thorough.
    Is Hone Health legit?+
    Yes. Hone Health is a registered telehealth platform with licensed physician oversight. Testing is done through CLIA-certified labs, prescriptions are real and regulated, and the platform has been operating since 2020. It is not a supplement company or a direct-to-consumer test kit without clinical review.
    Is Function Health worth it?+
    Function Health is worth it if you want the most comprehensive annual health baseline available and are willing to manage what you do with the results. It runs 100+ biomarkers including cardiovascular, metabolic, hormonal, thyroid and inflammatory markers. The value drops if you have no physician to act on the data. Pair it with a doctor who can interpret results and adjust treatment.
