Load-induced human skeletal muscle hypertrophy: Mechanisms, myths, and misconceptions
This study says that even if your body releases a lot of muscle-building hormones after a workout, it doesn’t actually make your muscles grow bigger—what matters is how hard you lift, not how much hormone you produce.
