It's a convenient, economical, time-saving way to get high-quality protein. It's great to have near training since it's very easy on the stomach. In my book's protein chapter, as well as other sections, I talk about whey.
This is a solid whey protein product without an offensive taste. For anyone that works out, protein supplementation is a must as it helps regenerate muscles bigger and stronger. For males, whey protein is particularly preferable over soy-based proteins as the latter may have slight estrogenic effects.
