My surgeon recommended this to me. I was very weak and in within weeks I was back to my old self. I was in bed 4 weeks it really helped me a lot. Excellent product. I use the milk chocolate with 2 percent milk taste great. I blend in a magic bullet blends well.

I love this protein powder. I use it every day. It tastes great, and it does not clump when I use it in a blender.
