Upper Quartile Hormones

Meaning

Upper Quartile Hormones is a clinical designation referring to circulating levels of key endocrine markers that fall within the highest 25% of the established reference range for a healthy, optimally functioning population. This range is often associated with youthful vigor, metabolic resilience, and peak functional capacity, distinguishing it from merely “normal” or “average” levels. The clinical goal of achieving upper quartile status is central to proactive longevity medicine and hormonal optimization.
