I take Optimum Nutrition's 100% whey protien. Two scoops are packed with 40 grams of protien, and very low carbs. The stuff if very cheap ($25 for 5 lbs.) and comprable to all the designer protien on the market right now. It's easy to mix - I just add two scoops to about 8 oz. of water in a water bottle, shake, and drink. I also eat a lot of chicken, and eggs - whic are cheap. From this, I gained 30 lbs. of mass and feel great. Good luck, Omar Tovar - El Paso, Texas.
