11-keto testosterone is primarily utilized in research settings to study its effects on androgen receptors and its potential role in modulating physiological processes. It is of particular interest in the field of endocrinology, where researchers investigate its impact on muscle growth, fat metabolism, and overall hormonal balance. Additionally, it is explored for its potential applications in developing therapeutic agents for conditions related to androgen deficiency or metabolic disorders. In the fitness and bodybuilding community, it is sometimes examined for its purported anabolic properties, though its efficacy and safety in this context remain under scientific scrutiny. Its role in influencing cortisol levels also makes it a subject of interest in stress-related studies.
