What your results tell you

Your biological age

How old your body really is, compared with your age in years, and how fast you’re ageing right now. It’s the number that shows whether your lifestyle is slowing ageing down or speeding it up.

Vitamins and minerals: Which ones your body needs more of, and which it doesn’t.
Supplements: What’s worth taking for your biology, so you stop paying for what you don’t need.
Genetic predispositions: Inherited tendencies towards certain health conditions, so you can act early.
Hormones: How your genes influence your hormone balance and how it shifts with age.
Psychological traits: How your genes may shape your stress response, mood and motivation.
Neurological health: Markers linked to memory, focus and long-term brain health.
Intolerances and sensitivities: Foods and substances your body may struggle to process.
Gut health: How your biology affects digestion and your gut.
Skin health: What influences how your skin ages, and how to support it.
Sleep: Your natural sleep patterns and what helps you sleep better.
Hair loss: Genetic factors linked to hair thinning and hair loss.
Fertility: Factors that can influence fertility, so you can plan ahead with more clarity.

Two tests, because women and men age differently.

Most biological age tests compare you against a mixed average of male and female data. Ours reads female biology and male biology separately, so your result is measured against people like you.

Questions before you order

Harley Longevity Club is based at 2 Harley Street, London. If you’d like to talk to us first, call 0203 507 0435 or email info@harleylongevity.com.

Do I need to give blood?

No. The test uses a saliva sample you take at home and post back free of charge.

How long do results take?

Your results arrive in your app 4 to 6 weeks after you post your kit.

What’s the difference between DNA and epigenetics?

Your DNA is the code you were born with. Epigenetics shows how your genes are being switched on and off by lifestyle, environment and age, which is how we measure your biological age and pace of ageing.

Will someone explain my results?

Yes. Every test includes an online or in-person consultation to take you through your results.

Who can see my results?
