I've used this protein powder for several years and I don't have an issue with the chocolate flavor. Let's not kid ourselves and pretend that all the protein shakes need to taste like 1000 calorie milkshakes. This is something where I put 7 ounces of water or so in shaker with a few ice cubes and it takes me like five seconds to drink it. So I'm not tasting it that long.

If you search for the vanilla flavor, it also has the $14 off savings. Op mentioned it in the description.

I'm tired of buying crappy vanilla flavors, trying to find a good one. Although this one seems to get good reviews, so I wonder if I should try it. Any thoughts on the vanilla flavor?

It really is. The savings savings of this vs dymatize isn't worth it for the awful fake chocolate flavor
