I love the efficient way of ordering these products! The shipment arrived within only a few days. For years, I was calling the MRC office I used to attend and asking them to ship them to me. It took a week or more and an investment of my time--including shipping fees. Recently, I discovered I could just click a few keys on my laptop and have the order sent within just a few days. I've been using the protein powder mixes since 2008! They help fill my tummy so that I feel more satisfied. I can only hope that they are truly increasing my metabolism!
