Excellent Quality and Mixability!
Flavor Name: Birthday Cake
Size: 1.34 Pound (Pack of 1)
This Dymatize Birthday Cake Pebbles ISO100 whey protein is top-notch in quality. It mixes effortlessly with no clumps or gritty texture; and the protein content is exactly what I want. The flavor is definitely sweeter than I usually prefer, but that’s the only minor drawback. Overall, it’s low in sugar and carbs, and gives a clean, satisfying shake every time. Despite the sweetness, still a 5-star product for me!

Definitely more birthday cake than pebbles!
Flavor Name: Birthday Cake
Size: 1.34 Pound (Pack of 1)
If you’re on the fence because it says pebbles and you’re looking for birthday cake, buy it. Or if you’re on the fence for any flavor or texture related reason… buy it. I’m very picky about protein. Drinks, bars, snacks… there are so few that I like. But this protein is incredible. Not clumpy, mixes easily, no chalkiness, minimal and not unpleasant aftertaste. As for the flavor, it’s as if you were drinking Funfetti cake mix, but nowhere near as thick. So great and more affordable than so many others. This will definitely become a staple in my house!

Worth it
Flavor Name: Birthday Cake
Size: 1.34 Pound (Pack of 1)
This has been my go to for a long time now! I dont get sick of the flavor, & always find myself going back to it despite trying other protein powders

Sent wrong flavor 2 times
Flavor Name: Birthday Cake
Size: 1.34 Pound (Pack of 1)
I rated 3 star due to being sent the wrong flavor twice. I would give 5 star if it weren’t for that. I’ve ordered 3 times and 2 out of those 3 times I’ve been sent the wrong flavor. I ordered birthday cake pebbles and was sent fruity pebbles instead. The barcode sticker on the side has been put on the wrong container which is causing issues. So beware you might get the wrong flavor. Now onto the pros- low calorie, high protein, mixes easy in a shaker bottle, not clumpy, tastes good, the cost is pretty good compared to other brands. It’s my favorite protein powder I’ve tried but I’m displeased I can’t get the flavor I want and like.

Great taste, great macros
Flavor Name: Birthday Cake
Size: 1.34 Pound (Pack of 1)
Delicious and I perfect macros for my fitness/nutrition goals. I’ve been using the dymatize brand for 6 months now. I got the fruity pebbles one first and got this one when it ran out. I mix this product with 1 cup Fairlife milk for taste and so that I only have to use half a scoop (stretches the proteins life). It tastes just like the milk that’s left over after eating cereal-especially the fruity pebbles one. For how I make it-Macros come to 140 cal, 25.5g P, 7g C, 0.5g F I also use this in my ninja creami protein ice cream recipe and it tastes like a Wendy’s vanilla frosty! I only wish they made for flavors like lucky charms, etc. It’s not chalky, doesn’t make me feel heavy, no tummy issues. Definitely recommend and I’m excited to try new flavors:)

Faint Vanilla Mixed with White Cheddar Cheeto Dust 🤢
Flavor Name: Birthday Cake
Size: 1.34 Pound (Pack of 1)
I never leave reviews, but I thought it would be helpful for me to do so here. I purchased the Birthday Cake Pebbles protein powder and just tried it for the first time. Let me tell you, when I first opened the container and smelled it, I got my first hint at how this would be. When making a shake and tasting it, I was absolutely disappointed. This does not taste like birthday cake at all. This tastes like a mix of a faint vanilla and white cheddar cheeto dust. I WISH I was lying to you. I will not be purchasing this again. Before this brand, I tried Orgain Organic protein powder birthday cake flavor and it smells and tastes GREAT! Texture not my favorite, but at least it tastes good! This stuff, however, no. It does not. I'm willing to try the regular fruity pebbles flavor, since so many have left reviews for that one, but the Birthday Cake Pebbles I will never get again.
