Here’s an easy weight-gain protein drink —

1. Get a whey-based protein powder.
2. Add 2 cups whole milk.
3. Add one banana.
4. Mix well with a hand-held blender OR a standalone blender.
5. Enjoy.

Mixing up protein and weight-gain powders ought to be the least of your worries. Focus on eating 6-8 small meals, get in some High Intensity Training, and get enough sleep. If you gain weight, you’re good to go.

If you don’t gain weight, re-assess your situation. Maybe you’re not getting enough sleep or food. For more weight-gaining tips, try The Hard Gainer’s Manifesto and Muscle-Build.com.
