Best Protein
Dymatize is easily one of the best protein powders I've tried. The biggest thing for me is taste-because a lot of proteins either taste chalky or way too artificial-but this one is smooth, creamy, and actually tastes like a milkshake. No weird aftertaste at all. It mixes super easily too (literally just a shaker bottle and you're good), and I never get clumps, which is a huge plus. I also like that it doesn't feel heavy or bloating after drinking it-it's really light compared to other brands I've had. Honestly, it feels more like I'm drinking something I want rather than forcing a protein shake. If you struggle with protein powders, this is definitely one of the safest picks.

Great for making muffins
I make protein muffins and I always use this product to enhance the protein in my muffin, along with coconut and almond flour. A great way to start the morning and it's easy peasy. Just pop a frozen muffin into the microwave and I have my breakfast.

Dislike
The brownie fudge chocolate flavor is horrible. I have been struggling for a couple months to finish it. It has a really weird flavor, doesn't taste as chocolate at all. VERY sweet, and when I say very that means a lot, at the point that you will have headaches drinking this protein because of the sweetness. Never buying it again.

Best flavor EVER MADE from any brand
This is truly the best tasting flavor hands down. I've tried other brands and flavors and believe me when I tell you, you'll be amazed. It's like the Chick-fil-A chicken of the protein world.

Too sweet
The fudge flavor is nice but it's too sweet, skip the sugar alcohols because they're unnecessary and not good for your gut health anyway.
