Trying to bulk up this year? A doctor says creatine and protein powder are the real MVPs for muscle gains—creatine gives your muscles more energy for killer workouts, and protein powder helps you hit your daily protein goals (hello, easy smoothies). But those over-the-counter 'testosterone boosters'? Total waste of money. Stick to the basics: smart workouts, good food, and these two proven supplements. Your future self will thank you! #Fitness #musclebuilding #fitness
