Biomedical illustration of the Methandienone molecular model, receptor, and DNA, an anabolic steroid. The steroid molecule passes through the cell membrane and binds with an androgen receptor in the cytoplasm. The receptor complex moves to the cell nucleus where it interacts with the DNA by transcription. The molecule is sometimes used for muscle development despite possible health risks.
