Your wiki link doesn't say anything about muscular dystrophy. It mentions treatment of wasting syndrome (e.g. from HIV or cancer) but that's a metabolic issue rather than a muscle issue. A quick googling reveals a 1965 paper that says anabolic steroids are ineffective, and some follow-up papers that talk about oxandrolone being modestly effective but mostly through glucocorticoid mechanisms (e.g. like Prednisone, not Testosterone)
