Achieving tissue selectivity

SARMs achieve tissue selectivity by targeting specific tissues like muscle and bone without affecting the prostate or other organs, reducing the risk of unwanted side effects. This is accomplished through their selective action on androgen receptors, which regulate gene expression in a tissue-specific manner.

Unlike anabolic steroids, SARMs are designed to have minimal impact on non-targeted tissues, making them a promising option for enhancing muscle growth with fewer adverse effects.

Non-steroidal SARMs are particularly advantageous in achieving tissue selectivity due to their selective binding to androgen receptors in muscle and bone cells while sparing other organs such as the prostate.

This targeted approach not only minimizes potential side effects but also enhances the prospects of using SARMs for therapeutic applications related to muscle wasting and bone fractures.

Non-steroidal vs. steroidal SARMs
