Love Pistachio Flavor
[This review was collected as part of a promotion.] Another great Rule One flavor. I added a scoop to my Pistachio cream sauce and pasta. All in all it’s an awesome whey.

Whey-ly Good!
[This review was collected as part of a promotion.] My favorite is Smore's. Taste is great without any chalky, grittiness. Rule 1 delivers their products a few days after ordering it online.

One of the best flavors out there!
[This review was collected as part of a promotion.] By far one of the best cinnamon cereal flavors out there, really tastes like Cinnamon Toast Crunch. Mixes very well in water, no clumps, glad it’s finally available in 5lbs.

Best birthday cake flavor protein on the market
[This review was collected as part of a promotion.] I used to get the Premire Protien birthday batter delight because I like birthday cake flavor and that’s the only birthday cake flavor protein drink I could find, but it was to expensive they didn’t sell it in a powder so I searched up birthday cake batter protein and found rule 1 and I don’t regret taking that risk on buying a tub.

Best protein powder ever!
[This review was collected as part of a promotion.] The rule 1 whey protein powder is the BEST I’ve ever had. It’s good in berry smoothies, in milk, or even in water. Love the flavor and that it’s not chalky like other powders!! Soooo worth it

609dadlife Rule 1 Protein
I have tried multiple flavors of Rule 1 Protein. Vanilla Ice Cream is my favorite. You can blend any fruit or Fit PB powder into it for a change up. I use 2 scoops in the morning and 2 at night. Taste great, high protein and lower calories to help get a solid build.

Rule 1 whey protein is the best!
I've tried the more popular protein powders that everyone says is the best (ON), but never had good luck with it dissolving when I would mix it with water. Rule one is the only protein I've ever tried that dissolves when I mix it with no lumps. It's all I will ever use from now on. And the flavor is awesome!

Love this protein!
I have tried other brands and always come back to Rule 1. Rule 1 is one of the few brands that includes BCAAs and tastes delicious. No weird texture or aftertaste.

Good everyday protein powder
I am mostly pleased with Rule 1 protein powder. I use it as my everyday protein. The flavors are sweeter than I would prefer and the the artificial colors are really unnecessary. Otherwise, it is fine. The protein powder mixes well in a blender or a shaker or with a spoon in my morning oatmeal. I don't get any clumping. A half scoop of salted caramel (with some frozen blueberries) tastes pretty good in my morning oatmeal. I use the fruity cereal or pistachio ice cream for a snack in the afternoon or lunchtime meal replacement. Mocha makes a nice coffee drink if I want something quick in the morning.
