Keep in mind that this program and its wiki is made for beginners. If you have already been lifting for several years, this program will not severely benefit you. It can help to "balance" your body. However, a proper weight lifting program should already possess most, if not all, the exercises in Starting Strength.
Now to the original poster: protein powder is not necessarily needed. To a common weight lifter, protein powder will not drastically improve weight lost or strength gain. Thus, no fat or slim milk is more than adequate to satisfy protein requirements, which is based on body weight and type. Remember to only drink milk after the work out.

That's interesting. I have read a book called the protein myth which says you really don't need more than 60-80g of protein even if lifting hard.
However then I read on forums people saying they didn't start seeing gainz until they upped their protein to 150-200g per day.
It would be interesting if this were a myth and I could stop eating all this bland chicken and choking down protein powder. And I'm talking specifically for putting on muscle, not just living on a vegan diet.
EDIT: Check that, the book is called How Much Protein by Brad Pilon. I actually have a link to the pdf if anyone is interested pm me.
As stated, protein requirements depend on body weight and type. Research a bit; i believe the starting point is 1-2g per kilogram for a body builder. From there, adjust to yourself. Remember that a good ratio of protein to carbohydrates is necessary to gain muscle. A big jump from 60-80g to 150-200g is unnecessary.
