At HormoneSynergy® Clinic and RetzlerRx®, we evaluate probiotics through a longevity-focused, clinical lens. As a nationally trusted U.S. longevity medicine clinic, we work with patients across the country who want evidence-based, clinician-guided solutions for gut health, metabolic health, and weight optimization.

Pendulum Life is one of the few companies that produces strain-specific, clinically validated probiotics designed to support gut function, metabolic outcomes, GLP-1 pathways, and overall healthspan.

Cardiovascular disease is the #1 cause of death in the US, prematurely killing over 800,000 people every year. For 50% of Americans, the FIRST sign of underlying cardiovascular disease IS a heart attack. Every 25 seconds someone has a heart attack and every single minute someone dies. If a person survives their first heart attack (only 50%), the average annual out of pocket cost (after insurance) for stroke or heart attack patients is $25,000 - $30,000 and does not include loss of income due to loss of productivity.

And, according to Kaiser those (out of pocket) costs can rise at minimum $100,000 if surgery is involved. With the latest advances in testing, thorough screening and comprehensive treatment, most of these early cardiac events and deaths are preventable.

Preventive cardiology as offered by Dr. Retzler focuses on a strategy to prevent you from not only going broke but being a cardiovascular death statistic.

HormoneSynergy® is currently the only clinic in Oregon offering Cleerly Testing, interpretation and consultation in clinical practice.
