I am devastated that Syntha-6 Meal Replacement protein shakes slowly but surely keep disappearing off the website!!! They are truly the best tasting shakes I have ever tried - and I have tried a lot, trust me! I really like the fact that these shakes have a great formulation - a bit of concentrate and isolate so you can take in the morning or right after your workout, a bit of casein so you can still take at night time to help you rebuild those muscles AND some enzymes to help you digest all those good proteins! Recommend to all as the best protein shake. If you have found this review helpful, please click 'yes'. Check out my page for more helpful reviews. Happy Shopping!
