Few people know that oatmeal was one of Arnold Schwarzenegger's main food choice. Oats are great even if eaten by themselves, but their effect can get multiplied tenfold if you combine them with other testosterone-boosting food products. As an example of a super protein-boosting breakfast, you can easily make, combine oats, with Vitamin D fortified milk, together with a sliced banana and a cup of Whey protein. You would have everything you need in your day with this simple food choice.
