The GOAT of protein powders. Clean profile/ingredients, great macros, and mixes easily with water. The flavors are spot on and don't have any aftertaste or hint of sweeteners (orange dreamsicle, cinnamon bun, and birthday cake are by far the best). I'm a fan of thicker/foamier shakes, and ISO-100 fits the bill. Easily worth the price if you're watching your budget.

  • 7 Gourmet Chocolate
  • 10 Fudge Brownie

I love this protein! I am a college athlete. I have tried soo many different protein drinks and this is one of the best I've had. I bought the fudge brownie and the gourmet chocolate flavors.. I have to say the fudge brownie is way better than the gourmet chocolate flavor! The fudge brownie tastes just like a chocolate shake. The gourmet chocolate is good, but the flavor isn't as strong. I recommend both flavors.. but I highly highly recommend the fudge brownie flavor!!

  • 10 Peanut Butter

I tried a sample of the Peanut Butter and WOW.. I felt like I was eating nutty butter cookie! I used 6oz of water which was the perfect amount for me (nice and smooth, not thick). I plan on purchasing this since I have been looking for a new protein powder.
