I've used whey off and on in the past few years.
First off, it *won't* make you gain unecessary weight like creatin because all it is is isolated *protein*. All it is, is an easy, isolated way to up your
protein intake in a low-carb, low-fat way.
That being said, I had a bad experience when I bought a cheap GNC brand of ISO-whey - I could barely stomach the stuff, and I threw up almost every time I drank it.
Will it cause you to grow muscle+weight in a shorter period of time? Hard to say. It's a slow and difficult in general for women, so it's not as if it's a magic bullet that will make you explode in lean muscle. Taken in moderation with a healthy diet and
strength training regime, it's definitely beneficial. I have found that my muscles are not as sore the next day, and I had made some good gains while on it. Just my two cents
