Effects of protein powders

leatitiaa

I use Nature's Best Isopure Protein powder (Dutch Chocolate) - $75 from GNC but only $42 from Amazon! I've noticed since drinking it after a workout (with crushed ice, some strawberry greek yoghurt and a banana mixed into an AMAZING smoothie), that it keeps me going til lunch but also helps with my muscle strength.

Keeps you full and helps you build muscle. Sounds great! Have you upped your protein in general or replaced other sources of protein with the powder?
