SARMs are not hormones genius.
They might as well be. It's kinda like saying tamoxifen is synthetic estrogen. Like Patrick Arnold said years ago, SARMs are pretty much anabolic steroids with a politically correct name. No, most of them a don't have a steroid structure. Some of them they can't even classify, like YK-11... Pat said it has a structure unlike anything he's seen before.
If you go on pubmed and type in trenbolone + SARM you will see how all anabolic steroids can be called SARMs.
