I got the sample pack and so far I've had Perfect chocolate, Milk Chocolate, vanilla and mint cookie. They are really good. Even better than the Syntrax. Especially the vanilla in my iced coffee. I may be ordering that one next time. The mint cookie is good but almost too sweet. The perfect chocolate seemed to have a little of an aftertaste, but not bad. Milk Chocolate tastes just like chocolate milk. And I mixed it with Water. It mixes well in a shaker cup. A lot better than the stuff I got at Walmart (Body Fortress). No yucky clumps or gritty-ness.

They do have a few more calories and carbs than Syntrax. They are between 110 - 140 cal and 2-6 grams of carbs and 23 g. Protein per scoop. The ingredients are:

• 
  Protein blend (whey protein concentrate, milk protein concentrate, egg albumin, hydrolyzed wheat gluten), natural and artificial flavors, soy lecithin, salt, acesulfame-K, sucralose, FD&C red #40.
  

Got them at Bariatric Pantry. About $20 for the sample pack. The 28 serving tub costs about $25 + shipping.

I am drinking my favorite right now. It's Met-rx Peanut Butter chocolate. The following is from the website. I would love to hear thoughts.
