Responses to intensive training and methandrostenelone administration: II. Hormonal, organ weights, muscle weights and body composition.

The hormonal levels of the gonadotropins, the weight of selected organs and of the triceps surae as well as body composition were determined in Sprague Dawley rats at 3 and 6 weeks after intensive training with or without a methandrostenelone (Dianabol) supplement (0.35 mg/kg/day). The controls were sedentary rats of similar age and weight at the start of the experiment. The dianabol treated rats in the sedentary and exercise groups had a depression of plasma LH levels. There were no differences in body weight, specific gravity, lean body weight, fat or %fat between the two trained groups. Dianabol had no apparent effect on the measured parameters other than a depression of LH.
