I love the product Protalyn:
http://www.bodybuilding.com/store/sf/prota-lyn.html
Its made locally here outside of Pittsburgh and a lot of times there are buy one get one free deals (on the website and just at the storefront itself). I definitely saw gains from it. Still have to eat a good diet, but its tough to get enough protein.
I like it best mixed with milk but you can mix with soy or water or whatever. The flavors are great which is a huge plus. Some proteins are just nasty. I've grown to really look forward to the stuff.
