Good stuff!
Employees were kind & willing to help me, as always! It’s nice to be taken seriously in a supplement shop as I’m a bigger woman. The protein I get is definitely worth the money. They have a nice variety to select from, as well.

Poor package and doesn’t provide number of servings as indicated
Definitely won’t be buying that brand anymore.

Rule 1 is my favorite. It has a great flavor and mixes so smooth.
