Androsterone is primarily used in the field of endocrinology and hormone therapy. It is often studied for its role as a metabolite of testosterone, helping researchers understand hormonal pathways and imbalances. In medical applications, it can be utilized to assess androgen activity in the body, particularly in cases of hormonal disorders or conditions like polycystic ovary syndrome (PCOS). Additionally, androsterone is sometimes incorporated into anti-aging and wellness supplements, marketed for its potential to support vitality and hormonal balance. In sports science, it is occasionally monitored as a biomarker to evaluate anabolic steroid use or natural testosterone levels in athletes. Its applications also extend to research in biochemistry, where it aids in studying steroid metabolism and its effects on human physiology.
