I saw HumaPro really benefit me as a replacement for protein calories. I was able to hit my macros at a much greater deficit and that enabled me to cut fat once I hit a plateau. I wouldnt use that method unless you have stalled in your weight loss because it simply is a great tool once you've hit a road block. I like to use HumaPro in my intra workout shake. After all these product scandals with intra MD and others, I basically just trust that HumaPro will be the best eaa and actually is what it should be.
