If that doesn't work then a great alternative to not being able to buy protein power locally is to use raw milk: the original protein drink. It
contains a synergistic balance of carbohydrates, protein and fat. Source RAW milk, which is a completely different thing than pasteurized milk. It contains the live enzymes and bio-available vitamins that are destroyed during processing.
