Which SARM types are best for lean muscle growth?

Yesterday, I was at the gym watching people talk about their supplements, and one guy mentioned SARMs for lean muscle growth. It got me thinking about which SARM types are actually best for this purpose since there are so many varieties with different selectivity profiles. I’m aiming to build lean muscle without unnecessary androgenic side effects, so I’m curious if muscle-selective SARMs are really the most effective or if dual-action ones might offer additional benefits. Has anyone here tried different types and noticed a clear difference in muscle gains? How important is the selectivity for lean tissue growth compared to general muscle support? Also, are there any practical tips for choosing the right SARM type based on individual goals or body response?
