What are SARMs?

I read this post from Tom Edward on the KD - Canada Facebook page: 

I heard back from Dr. Fischbeck last night. So SARMS are under active development for SBMA. We studied ASC- JM 17 and a lab in Tawain just received FDA approval to initiate a clinical trial. Paul Taylor's lab at St. Jude's did a study in mice and they were shown to be effective and at least 2 companies are interested in developing the drug. Diane Merry a researcher at Thomas Jefferson in Philadelphia is also working in the lab with other SARMS for SBMA. So it is having some positive results in the mice now let's hope it could translate into us humans.

So, I looked up SARMs and this is what I found...

Selective androgen receptor modulators or SARMs ...

are a novel class of androgen receptor ligands. They are intended to have the same kind of effects as androgenic drugs but be much more selective in their action, allowing them to be used for more uses than the relatively limited legitimate uses of anabolic steroids.
