ZURICH
Biomarker-Guided Consultations in Regenerative Science
At The Catalyst Clinic in Zürich, consultations are built around your individual biology — informed by precision diagnostics, scientific research, and longitudinal health monitoring.
Our approach is never trend-driven. Every consultation draws on peer-reviewed science and is conducted with rigorous clinical oversight by a qualified medical professional. We believe that any meaningful discussion of emerging compounds begins and ends with your data — not with generic protocols.
Our clinic brings extensive clinical and academic experience in peptide biochemistry and longevity science, distinguishing our consultations from lifestyle or aesthetic-only offerings.

Peptides in two minutes (VIDEO)
A short animated introduction to peptides — what they are, how they're structured, and why they're attracting growing interest in longevity and cellular biology research.
The video explores the science behind peptide signalling and touches on areas currently being investigated by researchers, including cell communication and structural biology. It is intended as an educational overview of an evolving field, not as a guide to any specific compound or personal use.
Dr. Ethan Hausman-Marquis, PhD in Cell and Genomic Biology, created this explainer to make the underlying science more accessible. If you'd like to discuss the research in the context of your own health profile, book a consultation.

Personalized Approach
AURION™ is The Catalyst Clinic's proprietary data intelligence platform. It aggregates information from consultations — including biomarkers, health history, lifestyle data, and personal goals — to help our clinicians structure a more informed and individualised conversation with you. AURION™ supports the clinical team in organising complexity, not in replacing clinical judgement. All recommendations remain the responsibility of a qualified medical professional. No automated output from AURION™ constitutes medical advice, a diagnosis, or a treatment plan.
Commonsense Protocols
We believe thorough diagnostic testing is a non-negotiable foundation of responsible clinical practice. Before any consultation concludes with a personalised recommendation, we require comprehensive bloodwork to establish your baseline health profile. Our clinical approach keeps all compounds separate — never combined in a single administration — to maintain precision, clarity, and individual monitoring of each element in your protocol. Follow-up diagnostics are scheduled every 4–5 months as part of our ongoing consultation programme, included within the monthly fee. This ensures your clinician always works from current data.

Comprehensive Consultations
Our consultations are thorough, unhurried, and built around you. Your clinician will review your full health history, current biomarkers, and personal goals to provide an informed, personalised advisory discussion.
A written summary following your consultation will outline the areas discussed, relevant research considerations, and any lifestyle or nutritional factors your clinician considers relevant to your profile. All recommendations are advisory in nature and remain subject to your own informed decision-making and the oversight of your treating physician.
Our Clinical Standards
Quality and rigour are foundational to everything we do. The compounds discussed in our consultations are sourced exclusively from compounding facilities operating under internationally recognised quality frameworks, including FDA-registered and GMP-compliant facilities in the United States and EMA-regulated facilities in Europe.
UK clients should be aware that these compounds do not hold MHRA Marketing Authorisations. Their availability and lawful use is subject to applicable UK law, and we strongly recommend that all clients seek independent medical and legal advice before accessing any compound outside of a licensed clinical setting.
WHY BLOOD DIAGNOSTICS ARE ESSENTIAL
BEFORE STARTING PEPTIDE THERAPY
Critical First Step
Comprehensive diagnostic testing is an essential first step before any peptide protocol. These investigations provide a baseline for safety and enable informed, personalised recommendations. Without diagnostic insight, peptide use may not be appropriate. At The Catalyst Clinic, all consultations include detailed biomarker testing and review.
Personalized Treatment
Comprehensive bloodwork provides a baseline, helping your provider decide if therapy is appropriate and how to tailor your protocol. Without it, peptides could disrupt balance and cause adverse effects, even if hormones already sit in the optimal range.
Maximize Benefits, Minimize Risks
Starting peptide therapy without bloodwork is a gamble. With thorough diagnostics, your provider can deliver safe, customised treatment that improves your chances of positive outcomes. Always choose a clinic that makes bloodwork foundational.
Programs Tailored to Your Biology
Each therapy is uniquely configured and optimized for your specific needs, with monthly protocol adjustments based on progress and biomarkers.

Benefits of Peptide Therapy at the catalyst clinic
biohacking anti-aging results with Targeted Treatments
Transparency is our raison d'être. At The Catalyst Clinic, we offer advisory services on the research use of peptides; we're committed to open and honest dialogue – nothing more, nothing less. Second, the ability to tweak your treatment plan. Maybe you need more BPC-157 and less GHK-Cu. These therapies are truly customized to you! And YOU are the center of that treatment, not the peptide!
Dr. Ethan is at the forefront of longevity therapies – with 15 actual years in peptides at his Los Angeles and New York City clinics and now abroad. He is an active member and speaker for the International Peptide Society, the American Board of Regenerative Medicine, the American Academy of Anti-Aging Medicine, and the International Longevity Alliance.
As a pioneer in peptide chemistry he has written two books on peptide therapy, Peptide-Based Cancer Therapies: A New Frontier in Precision Medicine and Exploring the World of Peptides: From Basics to Breakthroughs, and soon The Peptide Encyclopedia. He also hosts a weekly podcast, The Science of Age-less Living.
And it is all about the science! With a PhD in Cell and Genomic Biology from the Karolinska in Sweden and he knows and understands the metabolism, mechanisms and modes of action.
No clinical practitioner has the real lab bench background to really understand how these little marvels work.

What Are Peptides?
Peptides are short chains of amino acids acting as signalling molecules, influencing hormone production, cell regeneration, immune function, and cognitive health.

Why Blood Diagnostics Matter
Bloodwork is essential before peptide therapy. It provides a baseline, uncovers imbalances, and ensures treatment is both safe and effective.
Skipping diagnostics is a gamble. With comprehensive testing, we personalise your plan for maximum benefit and minimum risk.
