  • 10 Cocoa Pebbles
  • 10 Fruity Pebbles

Ok now I realize why tf people say cocoa and fruity pebbles is nasty. When I first got both flavors, I was pretty excited to try them. Now don’t get lost, but they both tasted like sh**(at first). So I would put one scoop in 10 OZ of milk. Then I kept experimenting and found the solution. 6-7 oz is perfect. I know from 7 OZ to 10 OZ doesn’t seem like a big difference, but it was a completely different taste. These flavors are BOMB. And it was worth getting 5 LBS of each. Highly recommend, and this is for all the stupid people that wouldn’t be patient and went on to write sh** reviews.

  • 10 Chocolate Peanut Butter

Can we just talk about Smooth Banana for a minute? It's definitely the under appreciated flavor here. Use it in smoothies or mix it with greek yogurt - the best. I also bought chocolate coconut and had to mix banana in it to give it taste. That flavor can go away. However, Chocolate Peanut Butter, you're the real star. We all know it... <3 U

  • 10 Fruity Pebbles

Fruity pebbles is spot on with flavor! Without a doubt my favorite protein. I prefer to add a little frozen cool whip to make it creamy but it's just as good by itself. A shake I actually look forward to enjoying! - BBCOM employee.

  • 10 Cocoa Pebbles

I am a BBCOM employee and I started using this product for after my workouts. I chose this brand and flavor based off the reviews of my coworkers. I started taking this with almond milk but it also tastes really good with water. It mixes very well so a mixer ball isn’t necessarily needed.

I absolutely love the cocoa pebbles. Different enough from the traditional chocolate flavor and stands out perfectly. The Fruity pebbles I found to be a little too sweet for my taste. As a whole, the iso100 is one of the best proteins on the market, not only having awesome flavors, but also some of the best quality available. -bbcom employee

  • 10 Cinnamon Bun
  • 9 Strawberry
  • 9 Orange Dreamsicle

Used with ketochow and heavy whipping cream Fruity pebbles ends up tasting like the milk leftover after cereal, though more flavourful. A little odd but not bad! Birthday Cake is the only flavour I have not liked. It tastes okay at first but leaves an awful aftertaste. Chocolate Peanut butter could use more of the chocolate flavour, still good. Cinnamon Bun is unbelievably decadent. You can even taste the frosting. Strawberry and Orange Dreamsicle are both solid flavours.

I ordered this on the recommendation of social media circles. I am not at all disappointed. I've been a vanilla protein user for a very long time, so getting a flavor like this was out of my comfort zone. However, I am NOT disappointed! I tried it with water at first so I could taste exactly how the product flavor is and it was good! It tastes like fruity pebbles! I think it'll be excellent with some coconut milk.

My friends and I have a little protein circle where we all just buy different flavors and give them a try. I have personally bought fruity pebbles, cake batter, and peanut butter. I have tried orange dreamsicle and chocolate peanut butter from my friends. I can honestly say without a doubt that fruity pebbles and orange dreamsicle are the two best protein powders I have ever had from an company ever. The taste is flawless and I honestly look forward to my protein shake every day. Chocolate peanut butter and cake batter are next in line after those two and still are in my top 10 proteins ever. Peanut butter is mehh, really foamy, and not my favorite. I will say that if you do not like sweet stuff, then these will not be the protein for you. I LOVE sweets and these take care of my sweet tooth and taste amazing. I don't think they taste artificial except for the peanut butter one. Mixes better than any protein I have ever had too. Overall, FANTASTIC.
