Amazingly great taste!
Wow this really tastes like the milk after eating a bowl of fruity pebbles! What a tasty treat! I got the chocolate milk shake too. Not nearly as good as this! Try it you won't be Dissapointed if your a fan of fruity pebbles!

Delicious protein!
I have tried the cinnamon and peanut butter flavors, and both are yummy! I mixed them into my oatmeal in the mornnings to give my breakfast a boost. They dissolve and mix very well, taste great, and help keep me full!

Great taste.
I don't know how much good it does for me but the taste is excellent when mixed in almond milk. Got vanilla and chocolate. It's like having a treat. Hope they keep the formula.

Nice when you need a change from basic chocolate & vanilla
I actually went into the store looking at a different GNC shake mix, but was happy to make the switch to this. I tried the Fruity Crisps in-store (with water) -- yes, it does taste like the cereal. Which is great, but if I'm going fruity, I would have preferred a nice berry flavor. I bought the Cinnamon Toast and Confetti Cake. I've only tried the cinnamon one (in almond milk), and it does taste like the cereal as well -- I think if I used a water-milk blend with ice, I could get that horchata feeling I want. Excited to try the cake one later. Honestly though, these fill me fast. I've had 2 oz of this shake and I'm already full. I have it with a light breakfast (just a multigrain plain waffle), and I'm pretty set for the morning. Looking forward to making some pancakes with these later, as well!

Coffee Creamer
I love this protein powder. I got the vanilla flavored and it makes a great coffee creamer. I use my small blender to mix it. It comes out smooth. Perfect for breakfast. I just started using it in my dinner smoothie and so far it's been good.

Very tasty
You can avoid chunks if you’re not mixing it right, but I feel like that’s any powder; it’s not as bad as some I’ve tried. I love this product really, mostly because the flavor... it doesn’t taste watered-down to me and it’s even better when I mix with soy milk or milk. I’ve tried powders that no matter how little liquid I added it just didn’t seem right but this one isn’t like that. My boyfriend bought the cinnamon toast kind (the only kind I’ve tried), and I want to try the other flavors ( I intend to) because I love this one so much!

Do you need to work out if you are taking this?
A shopper on Feb 28, 2018
BEST ANSWER: No. You can use this as a meal replacement or addition to your daily nutritional plan to increase your protein with a lower caloric impact. As always, it's recommended to combine exercise and diet if you are seeking specific results, but diet is a huge component on it's own. This supplement makes it easy to increase your protein ratio, if you are specifically tracking macros.
