What is a SARM?

Selective androgen receptor modulators or SARMs are a novel class of androgen receptor ligands.  Currently not approved by the FDA (USA) MHRA (UK) to treat anything.  They are intended to have the same kind of effects as androgenic compounds but be much more selective in their action, allowing them to attach to only the receptors they were intended to unlike old Anabolic Compounds.
