Drug‐induced liver injury associated with selective androgen receptor modulators in an adolescent patient

JPGN Reports, Volume 6, Issue 4, Page 515-518, November 2025.
ABSTRACT Selective androgenic receptor modulators (SARMs) have similar properties to anabolic steroids but bind to androgen receptors in a tissue‐specific manner. Studies have investigated the benefits of SARMs in promoting bone and muscle growth while limiting the adverse effects of androgenic stimulation of other organs.
