Bought 2 of these when it was on sale so now stuck with it. This protein makes so much foam and doesn't mix at all. Your left drinking a shaker full of chunks filled with foam. Even cleaning out my shaker takes extra time cause more foam.

This protein is one of the best tasting I’ve ever had. It’s like having a sweet treat during prep. Def going to buy again.

  • 10 Fruity Cereal Flavor

It's nice to see Cellucor break away from the mold in the industry of only offering 'peanut butter' or 'chocolate' spin-offs for protein powder flavors. Before trying this, I was hoping I could get a little childhood nostalgia and have it taste like Fruity Pebbles or Froot Loops, and it tastes EXACTLY like Fruity Pebbles. Just imagine... You smashed a bowl of Fruity Pebbles and the only thing left is the awesome Fruity Pebble flavored milk in your bowl... this is that personified, but with protein gains!

The Fruity Cereal is identical to Fruity Pebbles! Very good flavor and very accurate. The numbers are fantastic on this protein and Cellucor is definitely a high quality company. I use a wand mixer and it mixed ok; a little grit on the bottom of the glass when done. I haven't tried mixing with a spoon though. Overall a great product that I really liked.

Tastes great, it has a unique flavor however I think the flavor could get tiring quickly. Fortunately they have 3 flavors to choose from. Love the fact there is no chloresterol in this product. Just by changing proteins powders I cut out 45mg a day. It adds up, also less calories during my cut so I can enjoy my calories elsewhere. My new protein. Great job cellucor. This product is exactly what I was looking for.

  • 10 Orange Citrus

Overall this is a great product. The Orange Citrus taste absolutely amazing. I am a huge fan of anything orange so this was a must try. I loved it. The only problem I have with this protein is the mix ability. After shaking it for a while there is still some clumps of powder left over. Its also very foamy. So after all the foam finally settles you are left with quite a bit of your drink left. But over all every thing else is great!

  • 10 Fruity Cereal Flavor

Fruity Cereal has to be one of the best tasting proteins I've tried in a long time, reminds me of Fruity pebbles or Fruit Loops. Mixes great , without needing so much water the flavor is lost... Cellucor once again does not disappoint!!!

  • 3 Orange Citrus

When I first saw this product I couldnt wait to try it. When I tried it, I was quickly let down. The powder will not mix well, even in water, no matter how long you shake it. The flavor is also a total miss, just gross. I have two scoops out of a tub that I will most likely just throw away. Very sad considering the the quality of the protein.

Excellent is all I can say about this protein! Cellucor IsoPro is a great new protein that I was lucky enough to try out. Its from Cellucor, one of the most reliable brands that I regularly use, so I had high exceptions, and they were definitely met! First off, the ingredients. This protein is 100% Pronativ Whey Isolate Protein Powder, it is a grass-fed native whey. I like the act that it is grass fed, as I try to use and eat grass fed product whenever I can. It has 25g of protein per scoop which is great, along with being low in calories, almost no fat, and not cholesterol. That is excellent for a protein product. No sugar as well! Next, to the flavor. I was lucky enough to try the Strawberry Splash, and it is great! People do not usually think of strawberry as a protein shake flavor, but it truly is enjoyable and really works. After a long work, it is definitely refreshing. The texture is great, nice and smooth. As to mixing, I mixed one scoop with about 16oz of water and it was perfect! No clumps or grit either. I really do not have a bad word to say about this protein! I thoroughly enjoyed it and cannot wait to try the other flavors!

  • 10 Fruity Cereal Flavor

I can not say enough about this protein! I will start off by saying right when you open the lid, the smell of fruit loops hits you in the face. Now if you think the smell was good, the taste was great! It honestly tasted like at the end of a bowl of fruit loops, when you drink the milk at the end. Protein mixed well, foamed up a bit but did not take away from taste or texture. Macros are great! Was surprised to see 0 sugar with the taste I got. Lastly the price is a good avg price for protein. Overall will get again!

  • 10 Strawberry Splash

It started when I opened the container. The aroma of freshly picked strawberries was amazing. I tried this protein powder in a wide variety of ways. In a blender with and without creatine; in a blender with oatmeal, flax seeds and/or frozen kale; in a shaker cup with and without creatine and finally mixed with Freezinda to make high protein ice cream! It was all fantastic tasting. The 25 grams of native whey isolate in 110 calories is a great post workout drink, afternoon pick me up or a refueler after a long softball practice. It does tend to "foam up" a bit and have a "foam head" on top after mixing but that does not take away from smooth texture and the way it goes down. If you enjoy strawberries like I do, this is for you if you like to smile when you drink your protein!

Fruity Cereal is unreal how good it tastes! Mix this up in my fruity pebbles and it brings me on the cusp of an ******. The macros are spot on, price is spot on... Glad to see Cellucor finally bring an iso to the game. Can't wait for this to come out in a larger tub!

  • 9 Fruity Cereal Flavor

I am always impressed with Cellucor products. I love how they came out with this super clean protein. It mixes great, has a smooth clean taste, also macros are great! I gave this product a 9/10 because I didn’t like the flavor as much as I thought I would. It’s still good don’t get me wrong, taste just like the milk left in your fruit cereal when your done. If you love fruit cereal you will love this protein. I would highly recommend this protein!
