Every flavor I have had has been AMAZING. If you like Fruity Pebbles cereal you will absolutely love the product....flavor is exactly as you’d expect eating a bowl of cereal. Love the Dymatize as a post workout shake and meal replacement..I usually mix with water and it blends perfectly with no clumps. Using almond milk or another kind would enhance flavor but I love it all the same. No weird tastes like other brands may give. I’ll never use any other protein. Also easy on those who can’t tolerate lactose like myself. 10/10 would recommend.

Second attempt to post this review. Background - I strength training at 6am. Fasted (coffee and water only). I have a whey shake with water and some high GI carbs (like pretzel nuggets) after the one hour session (for a little insulin spike to promote muslce protein synthesis and to bring the cortisol back down). So i go with 1 1/2 scoops whey (40g) and about 15g Carbs = 200 cal. . I mix the shake before the workout and pop it in the freezer. Nice and cold after the hour session., Lately ive been been mixing 1 scoop Dreamsicle with 1/2 scoop Fruity pebbles. EXCELLENT COMBINATION. Much better cold. A little sweet but goes well with the salty pretzels. Bottom Line -. Both mix very well and excellent taste. No stomach issues. Worth the buy.

As a protein isolate, this stuff isn't horrible, although there are far more carbs per serving than there should be in a few cases. As for flavors : Cocoa Pebbles : Best of the batch I tried, actually tastes quite good, not overly sweet, and mixes well. Chocolate Peanut Butter : More straight up peanut butter and a combination, but still decent. Cookies and Cream : Tasted nothing like what I expected a C&C to be like, actually had hints of coffee at times, very odd, but not "bad" tasting. Fudge Brownie : No idea who named this, but there was no fudge or brownie involved, it was however INCREDIBLY overly sweet (uses both Stevia and Sucralose as sweeteners). Gourmet Chocolate : Again, no idea who named this one, but it was neither gourmet nor chocolate. The taste wasn't "bad" but it doesn't live up to the name. Dutch Chocolate : Less "Dutch Chocolate" and more "scoopful of cocoa powder". Seriously, that's what it tastes AND looks like, it's super powdery and has a slight granular/ chalky texture after mixing. Gourmet Vanilla : Awful. Tastes pretty nasty, didn't mix well at all in shaker cup (all kinds of massive clumps), and foamed like you wouldn't believe to the point where it actually popped the top open. Threw it in the trash after mixing 3 "shakes". Fruity Pebbles : I realize I'm in minority here, and it's possible I had a bad batch, but this is by far the most disgusting protein I have EVER tried. Not only that it's one of the most disgusting things I've ever tasted, period. It tasted like a mix of various chemicals. If I could give this a negative flavor rating I would, and it would be one hell of a ways down the scale.

Fruity Pebbles: I was very excited when this product dropped, and you know I ordered it right away. Keep in mind, this is a protein supplement. The fact they matched the flavor so well, and the powder is so light and airy, blows my mind. The sprinkles are a nice touch! Drinking it with milk isn't necessary, but I highly recommend it, reminds me so much of my childhood. Definitely would buy this flavor again, but it would never be a regular purchase so I don't go crazy. Gourmet Chocolate: Always my go flavor. It's rich, yet not too sweet and over powering. Great for post-workout, baking, meal replacement, whatever you need it for. I can have it regularly without getting sick.

I'm picky with my protein and have tried quite a few but this is the best I've ever had! I can't imagine how they could have gotten the flavor any better. Tastes exactly like the cereal. Also great macros, low calories, and doesn't make me feel gross after. So worth it!

I have tried soooo many protein powders, most of which I would just chug as they tasted awful. These are great!!! I mix them in my oats, drink them straight or make frozen shakes and no matter what I am always happy and not bloated after!

I don't normally bother to write reviews, but I decided to because there were no ratings for the chocolate caramel flavor. The flavors for this product are exceptional, and chocolate caramel doesn't take a back seat to either of them! You know its good when it still tastes like melted chocolate Easter candy when mixed with water. If you have any affinity for orange dreamsicles, you'll like that flavor too! Again, tastes like a melted dreamsicle. As simple as that. Nevermind that the product works well, is easy on the stomach before a workout, and the ingredients are as clean as you can get. I will be purchasing this product and these flavors again!

This is the best protein I have ever tasted!! Added 6oz of 2% milk and it taste exactly like the milk at the end when your done with your cereal. I bought the smallest size 1.6lb which was a mistake, just ordered a 5lb of fruity pebbles today and also bought a 3lb for the coco pebbles. This will be my new protein bar that I will be sticking with, can’t wait to keep working out just so I can drink this :)

It tastes amazing, usually use 1 and a half scoops after workout. You can combine it with pieces of dark chocolate too. Just ordered the cookies and cream, can’t wait.

This product is pretty good, here in Canada we don't have Fruity Pebbles and it was nice to try it. The taste is literally the same as Rivalus Rival Why (Fruity Cereal) for my Canadians out there. It's still a solid product for taste and how easy it is on your stomach. I would recommend for sure.

I've been using ISO 100 for 5 years. During that time, I've burnt through different protein powder brands here and there, but I always come back. Not only do the macros kick ***, the flavor is simply the best - and god knows how many brands and flavors I've tried over the years. Also, my stomach is sensitive and ISO 100 is very easy on my stomach. 10/10 would always recommend.
