Dianabol, also known as Methandienone, is one of the most popular and widely used oral anabolic steroids for gaining muscle mass, strength, and overall performance. Known for its rapid effects, it helps users increase size and strength quickly, making it ideal for bulking cycles. While it can lead to significant muscle growth, Dianabol is also associated with water retention and potential estrogenic side effects, so it’s best used in combination with other steroids or during controlled cycles.
