I really hope Costco starts selling the Double Rich Chocolate flavor at some point. 🙏 It's the best chocolate protein I've ever tried, rich but not overly sweet. I usually grab the 10lb bag from Amazon whenever it's on sale.

FWIW, I've tried a lot of different protein powder in my life and extreme milk chocolate is one of the worst flavors I've had. It tastes very artificial and chemical and I will never get it again.

Levels is a decent protein, but I can steel taste stevia drinking it with the water. Same goes for Ascent.

Seems to both be 80 servings just a scoop weighs 32g with 1 and 31g with another. I'd guess the flavor additions just weigh differently.
