## Questions & Answers

**Q: Has anyone used this for making things other than shakes? Like any protein desserts or protein balls? How does it mix?**
A: I stir Vanilla into my morning coffee as my "creamer." I have to sprinkle it in and stir each little dash to dissolve, but melts smooth and creamy! I have also used it in both cooked and raw oatmeal with milk. Could probably use it in anything similarly flavored like the peanut butter into homemade Reece's cups or cookies, Banana or other fruit ones into muffins - might need to adjust flour and baking time. I am going to try this now that it came to my mind! Thanks!

**Q: How many calories are in one scoop?**
A: 110

**Q: Is Rule 1 a total vegan protein?**
A: No, this is made from whey which is a dairy based product. If you’re searching for vegan look for pea protein based protein shakes.

**Q: When is frozen banana going to be available again?  why was it stopped?... tried it... was excellent... bring it back...**
A: It sells too fast

### ⭐⭐⭐⭐⭐ Chocolate Peanut Butter
*by A***H on 29 April 2026*

Chocolate Peanut Butter is my favourite flavour in Rule1 protein

### ⭐⭐⭐⭐⭐ Muy bueno

### ⭐⭐⭐⭐⭐ Best protein that I have ever taken
*by S***T on 7 April 2021*

I tried several different brands, and Rule 1 whey isolate is the best I have tried in my 11 years of lifting. The flavor is REALLY good, and the texture is milky smooth. It also mixes really well with yogurt, which makes it really easy to meet my daily protein goal. This is slightly more expensive than Pro Action Recor, which I feel is the best value, so I only buy Rule 1 when I am going through cutting cycles because it is somewhat of a premium item. If I can point to one downside, it is that we should NOT mix this with piping hot coffee because that causes it to curdle. I used to mix my whey with coffee so that I get my daily kick with some protein to start, but because the protein is so fine, it curdles much more easy in hot coffee (and that means you waste good coffee and good protein).
