Recreational AAS use appears to be associated with a range of potentially prolonged psychiatric effects, including dependence syndromes, mood disorders, and progression to other forms of substance abuse, but the prevalence and severity of these various effects remains poorly understood. There is no evidence that steroid dependence develops from therapeutic use of AAS to treat medical disorders, but instances of AAS dependence have been reported among weightlifters and bodybuilders who chronically administered supraphysiologic doses. Mood disturbances (e.g. depression, [hypo-]mania, psychotic features) are likely to be dose- and drug-dependent, but AAS dependence or withdrawal effects seem to occur only in a small number of AAS users.Large-scale long-term studies of psychiatric effects on AAS users are not currently available. In 2003, the first naturalistic long-term study on ten users, seven of which having completed the study, found a high incidence of mood disorders and substance abuse, but few clinically relevant changes in physiological parameters or laboratory measures were noted throughout the study, and these changes were not clearly related to periods of reported AAS use. A 13-month study, which was published in 2006 and which involved 320 body builders and athletes suggests that the wide range of psychiatric side-effects induced by the use of AAS is correlated to the severity of abuse.
