I’m sticking to this protein because of the good results. The gourmet chocolate flavor is so tasty!

  • 10 Orange Dreamsicle
  • 10 Chocolate Coconut

Reviews weren't lying, Dymatize hits a home run with ISO100, definitely among the best isolates I have tried. Flavors are rich, even on plain simple water which I what I have used mine with. The chocolate coconut is exactly like what the name says it is, it is not only a chocolate with a "hint" of coconut, I'd say it's 60% chocolate and 40% coconut, you can definitely taste both. Absolutely in love with this flavor, very refreshing. The orange dreamsicle tastes exactly like the ice cream pop I used to eat when I was a kid. Delicious. I can only imagine the flavors being even better if used with regular or almond milk. This is a real treat, especially when you are cutting like I am right now. The only reason I didn't give it a perfect 10 is because of the price, which is understandable for an isolate. Excellent product.
