Location & practical

  • Where are you located?Open +

    Calle Churruca 5, Madrid, in the heart of Chamberí. See the Contact page for directions, metro and parking.

  • Do you offer memberships?Open +

    Yes, our Human Performance and Body Recomposition memberships combine testing, personal training and medical oversight. See the Memberships section for details.

Gift cards

  • Can I buy a gift card?Open +

    Every test, assessment and package is available as a gift card. Choose 'Gift card' on any product and we'll email a redeemable code instantly.

  • How long are gift cards valid?Open +

    12 months from purchase. The recipient books whichever date suits them within that window.

Medical & safety

  • Is the VO2max test safe?Open +

    Yes. It's a maximal-effort test, but it's supervised throughout by our medical team with continuous monitoring, and you can stop at any moment.

  • How much radiation does the bone density scan use?Open +

    Very little, roughly a tenth of a chest X-ray, comparable to a few hours of natural background radiation.

  • Is the GLP-1 program right for everyone?Open +

    No, and we say so when it isn't. Eligibility is decided by our physicians at intake based on your health profile and contraindications. Consultation first, prescription only if appropriate.

  • Do you accept insurance?Open +

    We're a private lab and do not process insurance directly. We can provide an itemised invoice for reimbursement claims.

Results & reports

  • When do I get my results?Open +

    Key numbers are reviewed with you in person on the day. Your full written report, benchmarked against your age group, arrives within 48 hours.

  • Who sees my health data?Open +

    Only your care team. Your data is stored securely, never sold or shared, and you can request a full export or deletion at any time.

  • Can you share results with my doctor or coach?Open +

    Yes, with your explicit permission, we send the full report directly to them.

Preparing for your visit

  • How should I prepare for my tests?Open +

    For most tests, come hydrated and wear comfortable clothing. For metabolic and DEXA tests, arrive fasted (no food or caffeine for 4 hours). We'll send full prep instructions with your booking confirmation.

  • What should I wear?Open +

    Comfortable training clothes and the shoes you usually train in. For 3-D body composition scans, minimal tight-fitting attire works best, we have changing rooms and everything you need.

  • How long will I be in the lab?Open +

    Individual tests run 15–60 minutes, the Foundational assessment 90 minutes, and the Longevity and Performance assessments around 3 hours, including your debrief.

Booking & changes

  • What happens after I book?Open +

    Our team confirms your appointment personally by email within 24 hours, including exactly how to prepare for your specific tests.

  • Can I cancel or reschedule?Open +

    Yes. Cancel or reschedule up to 48 hours before your appointment at no charge. Within 48 hours, a 50% fee applies.

  • Can I book for someone else?Open +

    Yes. Book normally and add the recipient's details in the notes at checkout, or send them a gift card and let them book at their own pace.

  • Do I need to be fit to come?Open +

    No. Most of our clients are starting from scratch, the whole point is to measure where you are today. Protocols adapt to every level.
