I have skim milk. I used to buy for about $50 a two-week or so supply or Whey Isolate (New Zealand branded). It's about 31 grams pf protein per scoop. Can I just drink 3 or so glasses of skim milk instead of whey protien after a work out and get the same effects? I really like the taste of milk - a lot. Is it something about the isolate protein that I need (that it digests quicker), or is it better that I just stick to real food as I have heard so many times outside of the forums?
