Muscles are tissues enabling movement and strength. Muscular refers to having well-developed muscles or something related to the muscular system's function. Building muscle involves progressive resistance training and proper nutrition, leading to muscular hypertrophy and increasing muscle size and strength. The oral testosterone treatment enhances muscle growth and hypertrophy by increasing protein synthesis, improving strength, and accelerating recovery from workouts. Oral testosterone treatment is used to manage low testosterone levels.
