How old are you really ?

Biological age is :

  • The age of “your arteries”, your brain, your muscles… that is, the actual age of your body.
  • Often different from the chronological age.
  • A reflection of your life journey and lifestyle, and can be improved by following our personalized medical recommendations which are based on your personal results.


Why measure it ?

Biological age is an innovative health data which provides indications for personalized medical care for successful aging. It estimates the rate at which you are aging.

  • A biological age lower than a chronological age is associated with slower aging: YOU ARE YOUNGER THAN YOUR AGE
  • In the event of a biological age higher than your chronological age, our personalized recommendations, based on your specific results, will enable you to act to efficiently and reduce your biological age

Epigenomic biological age

Currently the most accurate way to estimate biological age


  • Medical and lifestyle questionnaire
  • Blood test at home or in a medical laboratory
  • Clear and detailed personalized report of your biological age and fragility factors
  • Concrete and personalized recommendations from a StarkAge Longevity doctor

How does it work ?



I order online, create my confidential profile and account on the secure StarkAge Longevity platform, and fill out the medical and lifestyle questionnaire.



I make an appointment to get a blood test.



My sample is processed and analyzed by our partner laboratories specialized in epigenetics.



I receive my result 4 to 6 weeks later in a specialized 1:1 medical consultation.



I can consult on my confidential account containing my epigenomic biological age and personalized report and recommended action plan with the steps to slow down my aging.

Yvanne (70 years old)

I wanted to organize a big trip to the United States but was afraid that it might be too much for me at this stage of my life. Learning that I am in excellent shape for my age (63) really allowed me to embark on this new adventure serenely.

Yvanne (70 years old)

Jean Pierre (67 years old)

Not having any scientific knowledge at all, I was afraid I wouldn't understand the test results and the detailed report, but I was very pleasantly surprised. The explanations and advice are very clear and geared towards practical application. I highly recommend.

Jean Pierre (67 years old)

The boost I needed

I knew that I didn't have the best lifestyle but knowing my biological age (50 years old) really opened my eyes to the consequences on my health. With personalized support, I now know how to get back on track.

Matthieu (45 years old)

A very useful gift!

My kids got tired of hearing me complain about my age and offered me a biological age test. Results: 65 years! A good surprise for me.

Mathilde (72 years old)

Comfort for retirement

As retirement approached, I worried about how I was going to age. Knowing my biological age (56 years old) reassured me. I have a more positive and serene outlook now t!

Jean-Yves (61 years old)

No surprises

A former top athlete, I was not very surprised with my results or the advice given to me. That said, the service and test is highly professional - I recommend wholeheartedly.

Josiane (70 years old)

Good value for money

I have wanted to know my biological age for some time but many tests are more gimmicky than scientific. StarkAge's solution strikes a good balance between rigorous science and affordability.

Laurent (35 years old)

I would have liked more details

The report and the explanations were clear and the advice practical and realistic, so I'm satisfied. Now I want to know more about aging, and was happy to discover the information section with understandable articles and videos that is very useful.

Valentin (52 years old)

A great original gift idea

My husband and I didn't know what to give my father for his 75th birthday. We had heard about epigenetics on TV, and then learned about StarkAge and decided to give it a go. Great choice! Dad is delighted to know that he is actually 71 years old and the results reassured us too.

Isabelle (50 years old)

Ginette (85 years old)

I have trouble getting around, and particularly appreciated having the possibility of a nurse coming directly to my home. I had questions to ask on the phone and the secretary took the time to answer them all.

Ginette (85 years old)

Quality service at an affordable price

A lot of my friends were talking about biological age and epigenetics and it made me curious about my biological age. StarkAge offers a service with a very good value for money.

Georges (81 years old)

A fun check!

I wanted to check if the daily efforts I make (gym, good diet) were really useful. My biological age is 29 years old, so I am clearly on the right track!

Marion (36 years old)

Very informative and clear !

My biological age is 73 years old. This news does not please me, but at least I was given clear explanations and an action plan to reduce my biological age. I am reassured that I can improve it now, and above all very motivated to take charge of my aging and improve my health! Can't wait to do another test in 6 months to see my progress.

You have questions ? We have the answers.

What is epigenetics?

Whereas genetics studies the composition of genes, epigenetics is concerned with how they are expressed. Small chemical modifications (epigenetics) are grafted onto certain regions of the genome and facilitate or restrict the expression of genes by our cells. Unlike genetic mutations, many of these changes are reversible and do not affect the DNA sequence. You can therefore impact your epigenetics, so it’s important to know your risk factors. This is now possible thanks to StarkAge Longevity’s epigenomic biological age test.

Why learn your epigenomic (or epigenetic) biological age?

If your epigenetic age is lower than your chronological age, you're on your way to staying healthy longer. But if your epigenetic age is older than your chronological age, it's time to modify your lifestyle.

How long does it take to receive my results?

Between 4 to 6 weeks. Once our laboratory partner processes your sample, and our specialist doctor has analyzed your results, you will receive your personalized report and recommendations in your personalized patient portal.

Where is my health data stored?

Your health data is stored in secure servers located in Europe. They are therefore subject to European GDPR standards, which guarantee respect for your privacy. Your sample has a unique secure identification number. This number guarantees anonymity and ensures the total confidentiality of all the information transmitted by the laboratory and by our partner doctors. With this encrypted security ID, you can retrieve your test results anonymously and securely from start to finish.

How does the epigenomic biological age test work?

The method for determining your biological age was developed by leading scientists in the field of epigenetics. Thanks to the DNA extracted from your blood sample, epigenetic data is obtained by next-generation sequencing. The biological age is then calculated from this information using algorithms designed and validated by the researchers.

Why does a doctor analyze the results?

Transmitting your epigenomic biological age to you without medical analysis means taking the risk of missing out on key information which will allow you to act on the aging of your body. Our doctors analyze the overall results: your epigenomic biological age, and all of the biological markers that make it up. Thus, we can detect weaknesses and the associated risks which can be masked by other indicators. The health professional's medical view of the results of StarkAge’s Longevity epigenomic biological age test thus gives you the keys to taking charge of your longevity.
