Flavorful! Great value.
The fruity cereal powder tastes pretty good, but falls a little short of Dymatize's same flavor. It breaks up well for protein shakes and drinks, and for the nutritional benefit the value for cost is great. Would highly recommend optimum!

Personally I find this flavor to taste too sweet, especially when I double up on scoops. It’s a great brand, just not the right flavor for me.

Decent flavor but not Optimum's best
The smell is right, like Trix/fruit loops, but the lemon/lime flavors overpower it. It's good for a change of pace from the usual chocolate/vanilla/strawberry

Good Protein for Macros, not that great of taste
This protein is really affordable for the serving size also the macros are great for a protein. My negative comes in because the taste isn't all that great. It's okay, I know that it's a protein supplement but the flavor isn't very good mixed with water. But if you make a protein Ice Cream or shake it will taste better. I would recommend to someone else for sure but don't expect the best tasting protein you've ever had.

Tastes just like Trix cereal
It's wild, but it tastes just like Trix cereal. I've made a few shakes with it so far and it tastes great. I'm looking forward to getting creative with it though and trying some desert recipes.

just what we need!
I really like how this is low in sugar, high in protein and just enough calories! the flavor is great to add to most things - easy to make a protein coffee hot or cold, easy to put into a smoothie for the family or blend with the morning oatmeal!

It’s an awesome protein powder for starting back into the gym. Does not taste like the cheap protein powder.

Great coffee creamer
Tastes good and mixes smooth. I use a scoop with just a little milk to make protein coffee creamer.

Awesome protein powder! Tastes great
Overall a great tasting protein powder with 24 grams of protein. Used it for an after gym protein shake. Added some peanut butter and bananas into it and tasted great. I got the vanilla ice cream flavor but I’m sure other flavors would be great aswell. Texture after blending it up was super smooth and not too chunky at all. Great that it’s only one scoop for the protein as other brands are multiple scoops.

Best flavor on the market!
I use this product after a work out or for a quick meal replacement when fasting. I got the peanut butter chocolate, best flavor I've had of any other protien product. Nothing didn't work for me was great all around mixed great and tasted great. I would say expert, because it's a premium product and most beginners aren't looking to spend big on products like this one yet. No other advice, but to keep supporting this company and it's great product.
