SARMs are comparatively new to bodybuilding fraternity.
SARMs and Steroids, both are effective and provide good results in bodybuilding. But the fact is, Steroids abuse causes irreversible side effects gynecomastia, baldness, infertility, etc. since they inhibit the natural secretion of testosterone.
Since SARMs are not steroids they do not suppress natural testosterone level.
Hence, they do not cause unwanted side effects and do not require PCT (post cycle therapy).
So, it is to encourage fitness enthusiasts to choose right products while they pursue their dream of becoming big.
