Free Testosterone Bioavailability Management

Meaning

Free Testosterone Bioavailability Management is the clinical practice of optimizing the concentration of unbound, biologically active testosterone in the systemic circulation. Testosterone exists primarily bound to Sex Hormone-Binding Globulin (SHBG) and albumin, leaving only a small, critical fraction as the ‘free’ hormone capable of entering cells and exerting its physiological effects. This management strategy focuses on manipulating the delicate balance between total testosterone and its binding proteins to ensure sufficient free hormone is available for receptor interaction. The goal is to maximize the androgenic and anabolic benefits without the need for excessive total hormone administration.
