something that implies quality at a low price.
lots of broke people right now. milk and other whey ingredient cost is skyrocketing, and it'll continue.
hard to break into that market without a really unique blend or product offering. Once you have that idea, the name will write itself.
Use "Muscle Milk" as your model. They have a product that tastes nearly as good as milk. The name writes itself. However, a product that is "just like every other protein powder" will be hard to market, hard to sell, hard to name.
My idea is to come up with a supremely unique product - and it'll name (and sell) itself!
