A Dbol cycle refers to the use of Dianabol (methandrostenolone), an anabolic steroid, to rapidly increase muscle mass and strength. Typically lasting 4–6 weeks, Dbol cycles are popular among bodybuilders during bulking phases. The steroid promotes protein synthesis and nitrogen retention, leading to fast muscle growth. However, it can cause side effects like water retention, liver stress, and hormonal imbalance. Post-cycle therapy (PCT) is crucial to restore natural testosterone levels. Medical supervision is recommended for safety.
