摘　　要：BACKGROUND Muscle growth promoters are being developed for the treatment of diseaseinduced loss of muscle mass.Ligandrol and ostarine are selective androgen receptor modulators(SARMs)with a non-steroidal structure and a presumably more favorable side effect profile.In recent years,these substances with or without“post-cycle therapy”(PCT)are often misused by amateur athletes aiming to promote muscle growth.At the same time,reports on their toxic effects on organ systems are emerging.CASE SUMMARY We report two cases of liver injury in young men who used ligandrol and/or ostarine for a few weeks followed by the use of substances for PCT.Acute liver injury occurred in both cases after stopping SARMs while on PCT.The clinical picture was dominated by jaundice and fatigue.The biochemical pattern showed a mixed type of injury with normal alkaline phosphatase and high concentrations of bilirubin and serum bile acids. Histological evidence showed predominantlycholestatic injury with canalicular bile plugs, ductopenia, and mild hepatocellulardamage without significant fibrosis. The patients recovered from the conditionafter 3 mo. The off target effects of SARMs were likely idiosyncratic, but ourreport highlights the yet unrecognized effects of other toxic substances used forPCT, supra-therapeutic doses, and the complete absence of monitoring foradverse effects.CONCLUSIONAmong muscle-building amateur athletes, SARMs (ligandrol or ostarine) and/orsubstances in PCT may cause cholestatic liver injury with prolonged recovery.
