What is you level of atheletism?
If you are not advanced or pro, you probibly don't need to supliment your protein intake. Even if you take extra protein, you have to work at an advanced level to build enough muscle to look bulky. Most people don't lift consistantly long enough to see much results. One thing women seem to forget is IF you start to look bulky, stop lifing weights. If you look bulky because you are eating/drinking extra protein, stop it, (it's probibly fat bulk and not muscle anyway).
