WHY LONGEVANCE

PERSONALISATION
BEFORE PRODUCTS.

Generic protocols start with products. Longevance starts by identifying what your biology is prioritising now.

Our experts interpret your profile, build your personal 90-day protocol and refine it as your results change.

QUESTIONS

BEFORE
YOU BEGIN.

After your initial conversation, you receive simple instructions for sending a small hair sample to our team. It is used to establish your initial bio-response baseline. Throughout the programme, scheduled check-ins and expert review allow us to assess your progress and refine the protocol. If further information is needed, the team will discuss this with you directly.

Yes. Longevance is designed to be completed fully remotely, from the initial sample and consultation through to delivery, check-ins and protocol refinement. In-person support may also be arranged in Zagreb, Croatia.

The programme includes your comprehensive bio-response analysis, a personalised peptide and supplement protocol, up to four selected peptides, monthly progress reviews, expert guidance and private coordination throughout the 90 days.

Your protocol is developed and reviewed by the relevant Longevance experts. Our team coordinates communication, delivery, scheduling and ongoing support, so every stage remains personally managed.

You may have a clear goal or a specific product in mind, and we take that seriously. Rather than beginning with a predetermined solution, we first assess what your biology is showing. The right approach may include that peptide - or it may begin by correcting the foundation that is limiting your progress. Your goals are part of the decision, while your results determine the protocol.

Your final review brings together what has been learned, clarifies the priorities that remain and defines the most appropriate next step. This may mean maintaining the foundations, continuing selected elements or discussing a further programme where appropriate.

No. The bio-response analysis is intended for informational and wellness purposes and is categorised as a Complementary and Alternative Medicine practice. It does not diagnose, treat, cure or prevent disease and should not replace professional medical advice.

Longevance is a highly personalised programme, with programmes starting at EUR 13,000. Full details are shared privately after an initial conversation, once we understand your goals and confirm that the programme is suitable for you. Availability is intentionally limited due to the level of personal attention and coordination each programme requires.
