1. What Are Anabolic–androgenic Steroids?
   

Definition: Synthetic derivatives of testosterone that promote muscle growth (anabolism) and masculinization (androgenic effects). Common Forms: Oral compounds (e.g., methandrostenolone), injectable esters (e.g., nandrolone decanoate, boldenone valerate). Mechanism: Bind to androgen receptors in muscle cells, increasing protein synthesis and nitrogen retention.
