I went to GNC yesterday and asked which protein powder was best for me. He recommended the Pro Performance AMP Amplified Recovery Protein XR. He said it was good for muscle gain. Have you tried this one? Do you have a favorite?
so far I've only tried Dymatize Iso-100 smooth banana flavor whey protein isolate, and it is awesome and mixes well with everything i tried: milk, chocolate milk, almond milk, all that with bananas and blueberries, and the ultimate test, my veggie/fruit smoothie with lots of flavors to meld with (my new protein mix does NOT go well in this UGH). All delicious... good protein source.
