I already know I love Dymatize. My mom just started taking whey to up her protein intake and asked me which brands I like. Dymatize of course! She didn't feel it was worth the extra money when she can get Costco protein for super cheap, so I bought her a 5 pound tub for Christmas. She's a convert now! Cinnamon Bun: This is a bit of a cheat for me because I've had this flavor before, but I love it so much. It goes great in coffee, awesome as pancakes, satisfying mug cake. Mixes pretty easily. Chocolate Coconut: LOVE the flavor. Thinking I need to make a coconut blondie with it to pump up the Mars Bar flavor! It does not mix well with just a spoon unlike most of the other Dymatize flavors (maybe because of the coconut flavor?), so if I'm enjoying it as a shake, I pull out the blender. That being said, it is amazing tasting. I have also used it in oatmeal and made little protein balls coated in coconut. Hnnngg Chocolate Fudge: I'm usually not a big fan of chocolate, but since my favorite way to drink my protein is with coffee, I chose this flavor as one I've not had before. Because it's Dymatize, I knew it would be good. Really spot on flavor, goes great in coffee. Probably the only way I would drink it normally since I love my other flavors for pancakes, etc.Mixes easily as well.

The Gourmet Chocholate is the best protein powder I've ever tasted. I usually love peanut butter, but this Chocolate Peanut Butter has a "burnt peanut" taste. Also, the protein doesn't upset my stomach like others.

After having started this protein a year back, there is no turning back to any other product. It tastes absolutely fantastic and makes u feel good even after intense workouts. and yes, no bloating :) My favourite post-work out protein shake ! Highly recommended !!!!

The best tasting protein powder ever. I just can't describe the experience and knowing that its gluten free and has been sweetened with stevia adds to the points. Best ever.
