You can grow the same amount of muscle in less time by using drop sets instead of regular sets.

Investigating the Effect of the Tonal Drop Set Mode On Elbow Flexor Hypertrophy
Drop sets built the same amount of muscle as regular workouts, but did it faster — so you get more muscle growth for every minute you spend training.
Effects of Drop Sets on Skeletal Muscle Hypertrophy: A Systematic Review and Meta-analysis
Drop sets build muscle just as well as regular weight training, but they take much less time—so you get the same results faster.
Effects of drop sets with resistance training on increases in muscle CSA, strength, and endurance: a pilot study
This study found that doing one heavy set followed by lighter sets without rest (drop sets) built muscle just as well as doing three heavy sets — but it took less time. So you get the same muscle growth faster.

Drop-Set Training Elicits Differential Increases in Non-Uniform Hypertrophy of the Quadriceps in Leg Extension Exercise
The study found that drop sets and regular workouts built muscle similarly, but it didn’t check how long each workout took, so we can’t say if drop sets are faster or more efficient.
The study found that drop sets didn’t make muscles grow bigger faster than regular weight training — even though they might take less time, they didn’t give any extra muscle growth benefit.
