If you have a sensitive stomach, stay away
This oroduct makes me so constipated it's nit even funny. This is true for all Dymatize powders for some reason personally. Great taste, tastes like hot chocolate, but since switching to a bew protein powder I haven't had any digestion issues. That's why I cannot give this a high rating.

Tastes great. Macros are perfect.
This has been my go to protein for pre/post workout for about 10 years, It's the best tasting and the macros are perfect. I have a portable Ninja blender and will add one scoop of this with some peanut butter powder, banana, and some ice for a snack.

eh
I suppose it's better than other protein powders I've tried but there is something about the aftertaste, maybe the stevia, that is very unappealing. I love the chocolate peanut butter and it doesn't have stevia. They both have sucralose, so I don't think that's my issue. Trying to finish it has kinda sucked. Choco pb for the win!

Product filled less than halfway full.
Love the taste but my rating is one star because the container is filled LESS than halfway full. You are asked to pay all this money for protein, yet I open my container expecting it to be somewhat decently filled and it?s not. I am NOT happy - they should be ashamed of themselves. I feel jipped
