I also have problems understanding your post. Here is what I can tell you.
You can buy whey protein powder (or bars) in any nutrition store (GNC but expensive) or online store (bodybuilding.com). Whey is a soluble form of milk protein. Hence, you can in a sense get whey from eating diary product, but you'll be eating fat as well. The most popular form of eating whey protein is to buy a container of whey powder (comes in various flavors), mix them with your favorite drink and chug.
There are many different types of protein, whey is one of them. There is casein, which is the insoluble protein from milk (opposite of whey). Also there are egg proteins (albumen) and soy protein as well. All of these can be bought in your local nutrition store or online. Hope this answers your question.
