I tried both the citrus and cereal flavor and both taste great. The problem is that neither flavor I tried mixes well at all so you are left with foam and more than a few chunks of the powder, making it hard to drink. My score would increase significantly if they could figure out how to make it mix better.

I did read the reviews before I purchased this and there were mixed ones. I got it when it was on sale. I purchased the Fruit Cereal so that it would help satisfy my sweet tooth. I didn't have any issues with the mixability, I did however experience the foam. The taste was great, it tastes like the milk after eating a bowl of fruit loops. Overall I think it's a good product.

Takes a little more to mix by hand but still doable. Flavor is identical to fruit loops or fruity pebbles, phenomenal

Bought these the strawberry splash and the fruity cereal flavor when they were on sale. Worst mistake I have ever made when shopping for protein. I will start with the taste, this tastes terrible, it has an sour acidic taste and a chalky texture. While this maybe somewhat common among protein powders, and when it is the case I would just slam it back and get my 25 grams of protein. However, this protein not only tastes terrible with a terrible texture, it also has terrible mix-ability as it clumps after you shake it (mind you I am using water), and to add insult to injury it FOAMS up when you try to shake it. So not only does it taste absolutely terrible, it forces you to wait to drink this nasty concoction just to get your 25 grams of protein. Seriously disappointed, I have never felt this way about cellucor/nutrabolt products as I have used many of their other supplements (c4, alpha aminoes, super hd, their regular whey, c4 50x).They really slacked on this I would give negative ratings if I could. Writing this as i wait for the foam to settle so I can get my 25 grams of protein and I absolutely regret getting this.

Awesome protein a little on the expensive side but I was not displeased with the product. Mixes great and tastes great (cereal flavor) good nutrition profile as well. Orange citrus tastes like orange death however.

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.

  • 10 Fruity Cereal Flavor

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!
