Andarine is primarily used in research settings to study its effects on muscle growth and bone density. It is often investigated for its potential to treat conditions like muscle wasting diseases and osteoporosis. Additionally, it is explored for its selective androgen receptor modulator (SARM) properties, which may help in targeting specific tissues without the side effects associated with traditional anabolic steroids. Its application in bodybuilding and athletic performance is also a subject of interest, though it is not approved for human use in these contexts.
