The purpose of this study was to investigate the effects of anabolic steroids (AS) abuse on liver enzymes activity and lipid profiles in male bodybuilders. 40 well-trained bodybuilders, with 20 self-reporting regular AS use and 20 self-reporting never taking AS (NAS) were recruited for this study. Participants reported to the laboratory for blood sampling to assess liver enzymes activity (Aspartate transaminase [AST], Alanine aminotransferase [ALT] and Alkaline phosphatase [AP]), lipid profiles and fasting blood sugar (FBS). Moreover, maximal strength and muscle volume were measured. The results indicated that AS users had higher strength in the bench press (113±11.8 vs. 93.7±13.3 kg) and leg press (329.5±40.4 vs. 248.5±41.0 kg), muscle volume (arm, 41.2±3.5 vs. 35.1±4.2 cm and thigh, 60.6±6.4 vs. 53.7±5.6 cm), LDL (179.2±34.1 vs. 155.8±37.7 mg/dL), TG (166.5±74.4 vs. 126.9±48.2 mg/dL), TC (253.2±59.6 vs. 143.5±48.0 mg/dL), AST (53.2±14.3 vs. 34.5±11.11 IU/L) and ALT (53.5±15.1 vs. 33.3±7.8 IU/L) (p < 0.05). However, NAS users indicated higher HDL (43.5±15.2 vs. 30.7±10.0 mg/dL) and AP (82.7±30.6 vs. 75.6±30.1 IU/L) (p < 0.05) in comparison to AS users. In conclusion, AS abuse is associated with alterations in liver enzymes function and lipid profiles that, represent an increased risk profile in athletes who used AS.
