How to choose the right weight gainer

Choosing a weight gainer depends on your goals, body type, and calorie needs. A good mass gainer should fit your training plan and dietary preferences.

Check protein-to-calorie ratio: Aim for a formula that balances calories with protein content to ensure you're gaining muscle, not just fat.
Consider your caloric needs: If you're struggling to gain weight, go for higher-calorie options.
Choose quality ingredients: Avoid products with too much added sugar or cheap fillers. Look for whole-food sources of carbs and protein.
