Customer Reviews: The best post-workout drink on the market!July 1, 2010 JZ(USA) This is the perfect Post-Workout shake for any Keto dieter as it has no carbs. It also contains a blend of the most anabolic and anticatabolic ingredients (leucine blend, whey hydrolisate and casein. It tastes really fresh and fruity so I can have it also in the morning after a rough night and it energizes me much better than a good old milkshake-tasting drink. Both tastes are great.
