Why Protein Powder Matters for Muscle Growth
Protein is the building block of muscle. After intense workouts, your muscles need protein to:
- Repair damaged fibers
- Grow stronger and bigger
- Improve recovery time
Without enough protein, your progress in the gym will be slower — no matter how hard you train.
