About flexible subscriptions

How does a subscription work?

When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don't worry - you have full control over when this will be, and you can change/cancel it anytime.

When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your biomarkers change. You'll be charged per test kit (rather than monthly, for example).

Why subscribe to multiple tests?

One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what's tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

What is a cortisol test?

A cortisol blood test checks the levels of cortisol in your blood, which can be an indicator of stress. Testing your stress levels can help identify why you’re feeling tired, aren’t sleeping well or are having mood changes.

How to test cortisol levels at home

Your cortisol levels rise and fall throughout the day, but are highest in the morning, when you wake up, so it’s best to collect your blood sample before 10am or within 3 hours of waking up. Our cortisol blood test kit has everything you need to collect a blood sample at home, including free return postage to our labs. Our doctors will review your results to provide feedback on your levels and advice on how to improve them.
