Ibutamoren Mesylate is primarily used in research settings to study its effects on growth hormone secretion and muscle growth. It is often explored for its potential to increase muscle mass and improve recovery in conditions associated with muscle wasting or weakness. Additionally, it is investigated for its possible benefits in enhancing bone density and improving sleep quality. Researchers also examine its role in addressing age-related decline in growth hormone levels and its impact on overall physical performance. However, its use in humans remains experimental and is not approved for medical treatment outside of clinical studies.
