I am now currently trying out syntha 6. best flavour for this particular protein shake is chocolate milk. I have tried the chocolate and peanut butter but it doesnt taste as nice as the chocolate milk even though the review given at some sites are the same. This protein has only a servicing of 22 grams of protein per serving. Gains, well no pain no gains, no matter how much protein you drink, you wont gain any muscle if you dont work hard and lift weights constantly. In my case, lifting weights are only for my health and be healthy and fit, not becoming a bodybuilder.http://ts1.mm.bing.net/th?id=I.4511863971907368&pid=15.1&W=160&H=160
