What is Myostine YK-11?
YK-11 is a selective androgen receptor modulator (SARM) that could offer many advantages in researchers studying fitness & bodybuilding. Although it is one of the newer SARMs on the market, YK-11 has become very popular in researching performance boosting based sarms.
This SARM works by forming connections with the androgen receptors of the bones and muscles and triggering anabolic effects. Specifically, YK-11 obstructs myostatin, which is a component that is produced by cells to prevent muscle growth . According to research, the obstruction of myostatin increases muscle function and prevents muscle atrophy, which is the wasting away of muscles . Research indicates that YK-11 can increase lean muscles [1, 3] and increase the hardness of muscles [1, 3]. While further research needs to be conducted, this SARM has also been identified as having no anabolic side effects [1, 3].
