Emerging anabolic drugs - investigation of the in vitro and in vivo metabolism of selective androgen receptor modulators
Selective androgen receptor modulators (SARMs) are a novel class of orally active, tissue-selective small molecule androgen receptor ligands with potential use for human therapeutic purposes. While SARMs show similar myoanabolic effects to anabolic androgenic steroids with reduced side effects, …
