  • 8 Orange Dreamsicle

Only been using this for 2 days now and already love it. However I wouldn't get the Orange Dreamsicle flavor again as the flavor has a powerful artificial kick imho. Mixes fantastic with water and requires little shaking. The shakes are thicker rather than watery and go down with ease.

  • 9 Chocolate Coconut

Flavor is great, especially mixed with 8 oz skim milk. DO NOT put in too much liquid or it literally tastes like nothing. Mixes very easily and is satisfying as a small snack, but I would not recommend for any type of a meal replacement.

  • 9 Rocky Road - Exclusive!

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.
