This is the Phd Synergy ISO-7 which was recommended by my instructor. It came with a free shaker but the quality of the shaker is not as good as my Maximuscle shaker, which I got when I purchased Maximuscle products about two years ago. Well, this Phd Synergy ISO-7 provides whey protein and other nutritious ingredients as well as acts as a fat burner to help the users in their training. My instructor also mentioned that he was able to lift more weight by using it. So far, I have not been able to experience that. I am only hoping on gaining weight by using it and exercise regularly so that my weight is distributed evenly. By the way, I bought the chocolate orange flavour and it tastes like Kit Kat with orange flavour.
