No doubt it’s effective, you can feel this lean shred and energy. But orange ice cream was horrific, wasn’t tasty, it was a mission to drink. Thats how hard it was...

The best protein I have ever tasted. The taste of it is good, it makes you feel like it's actual natural strawberries. I love it

Tried a few, obviously. Like it for the LACK of ingredients. Could do without the soy, every brand seems to have it though. NO CARAGEENAN, super bonus. Flavors are as good as any brand. Thin texture, because, NO CARAGEENAN, well worth the trade.

The product is okey-ish. The flavor is the worst of the worsts. Very strong, sweet and unpleasant. After you are having it - you need liter of water to flush the sweetness from your mouth. I would recommend other flavors such as Gourmet Vanilla, etc.

I LOVE this protein shake!! I ordered it after comparing the label with what I was using before and I'm so glad I did! I mix it with unsweetened almond milk and it tastes like creamy dessert after a good workout! Can't wait to try the other flavors!

  • 10 Fudge Brownie

Hands down the Fudge Brownie is my flavor-favorite. It mixes smooth and tastes great with just water, or when I crank it up with some ice, a half-cup of frozen strawberries, peanut butter and oats. It's like bodybuilder foreplay.

I can honestly say that I am not a fan of Chocolate Peanut Butter protein, but this product showed me how wrong I was. Neither of the flavors were over bearing so it was a great mix. I did not buy this product, but a tub was given to me as a prize. Can't beat free stuff, and I will purchase this when I have used it all up. Very good flavor.

This is as good as a Reese’s milkshake but not as heavy on the stomach and without sugar.

  • 9 Cookies and Cream
  • 6 Gourmet Vanilla

Although I didn't buy Dymatize ISO100 from as I live in Australia might do in future. I did try two flavors and if you are confused what to go for between these two i'll recommend Cookies and Cream as the Vanilla one was a bit odd for me. I'm currently going with Vanilla as I bought it recently to give it a try but Cookies & Cream all the way!

  • 6 Gourmet Vanilla

Great product, good results, gives the protein you need without carbs and fat. However Gourmet vanilla flavor was a disappointment, its too watery and quite flat on the vanilla taste.
