SOURCE-LINKED STUDY SUMMARY
"Anabolic" effects of methandienone in men undergoing athletic training.
What was studied?
A double-blind crossover experiment examined whether methandienone (Dianabol) changed body composition, strength, performance and endocrine function during weight training.
What changed?
Body weight, lean mass and muscle size increased with methandienone. Strength and performance improved during both training periods, without a significant drug–placebo difference. Plasma testosterone decreased, while plasma cortisol and urinary cortisol excretion increased.
Who was studied?
The study involved 11 athletic men undertaking a course of weight training.
Studied exposure
Methandienone was given at 100 mg/day for 6 weeks, with a placebo period for comparison. The abstract does not specify administration route.
What remains uncertain?
The authors could not establish whether the body-composition changes reflected an anabolic effect or increased intracellular fluid.
