Epiandrosterone is primarily used in the field of endocrinology and hormone therapy. It serves as a precursor in the biosynthesis of other steroid hormones, making it valuable in research and clinical settings for studying hormonal pathways and imbalances. In sports and fitness, it is sometimes explored for its potential anabolic effects, though its efficacy and safety remain under scrutiny. Additionally, it is utilized in anti-aging and wellness formulations due to its role in supporting hormonal health and vitality. Its application in medical diagnostics also aids in assessing adrenal function and steroid metabolism disorders.
