Membership Terms

Last updated: November 11, 2026

These Membership Terms apply to Zenos Membership (Foundation, Plus and Executive). They work together with our Terms of Service, Privacy Policy and Return and Refund Policy. If these Membership Terms and the Terms of Service conflict on a membership topic, these Membership Terms apply.

1. What your membership includes

Each membership level includes recurring at-home blood testing, SystemAge biological age testing, access to the Zenos agent and a monthly supplement protocol. What changes between levels is how often you test and how many supplements you receive:

  • Foundation: 4 blood tests a year (quarterly), 1 SystemAge test a year, 2 supplements a month, Zenos agent included.
  • Plus: 6 blood tests a year (every two months), 2 SystemAge tests a year, 3 supplements a month, Zenos agent with escalation support.
  • Executive: 12 blood tests a year (monthly), 2 SystemAge tests a year, 5 supplements a month, Zenos agent, a physician on file and a quarterly review.

The women's protocol is available at every level. Testing panels, schedules and supplement selections may be updated as our Scientific Advisory Board reviews the program. We will tell you before any change that reduces what your level includes.

2. Billing

  • Your membership is billed monthly, starting on the day you join, until you cancel.
  • By joining, you authorize us to charge your payment method each month at the price shown at checkout, plus any applicable taxes.
  • If a payment fails, we will try again and contact you. Shipments and tests may be paused until payment is completed.
  • If we change the price of your level, we will notify you at least 30 days before the change takes effect. You can cancel before then.

3. Changing or cancelling your membership

  • You can cancel at any time from Subscriptions in your account, or by emailing marketplaces@zenoshealth.com.
  • To avoid the next charge, cancel before your next billing date. Your benefits continue until the end of the month you have already paid for.
  • To move to a different level, contact us. The new price applies from your next billing date.

4. Testing kits and results

  • We send each testing kit according to your level's schedule. Follow the instructions in the kit, including any fasting or timing guidance, and return your sample as described.
  • Samples are analyzed by third-party laboratories. Results times depend on the test and the laboratory; we will tell you when your results are ready in your account.
  • If a sample cannot be analyzed (for example, not enough sample, or it arrives damaged or late), we will send a replacement kit once for that test cycle.
  • At-home blood testing is not available in every country or region. We confirm that testing is available at your address before your first kit ships.

5. Medical disclaimer

Zenos Membership is a wellness program. It does not diagnose, treat, cure or prevent any disease and does not replace care from your own doctor. Test results, biological age estimates and recommendations from the Zenos agent are for information only. Talk to a qualified healthcare professional before you change your medication, diet or exercise, and seek medical care right away if you have symptoms or a medical emergency.

Our supplements are dietary supplements. Statements about them have not been evaluated by the U.S. Food and Drug Administration.

6. Refunds

  • Supplements included in your membership are covered by our Return and Refund Policy.
  • Laboratory tests that have already been processed and the months of membership already used are not refundable, except where applicable law requires otherwise.
  • If you live in the European Union or the United Kingdom, you may have a statutory right to cancel within 14 days of joining. If you have already used part of the service in that period, we may deduct the value of what you used.

7. Your data

Your test results and health information are handled as described in our Privacy Policy. We use them to deliver your membership, including your results, your protocol and the Zenos agent. We do not sell your health information.

8. Eligibility

You must be at least 18 years old to join. If you are pregnant, breastfeeding, taking medication or have a medical condition, check with your doctor before joining or starting any supplement.
