Great

I've been using Rule1 Casein protein powder for a few months and love it! The slow-release protein is perfect for nighttime, tastes great, mixes well, and is easy on my stomach. Highly recommend!

chocolate relief

I use this as a recovery during after bike rides and the great taste is something to look forward to after an exercise session.

Nice vanilla flavor

This has a pleasant vanilla flavor and mixes well (I use a shaker cup). The protein in it is 100% casein and there is no added sugars. The product gluten free (no disclaimer about using shared production lines like some products that are still confusingly labeled "gluten free"). I like the fact that it comes in a larger size since it's something I use regularly. I wish it came in a bag instead of a tub, but that's the only complaint I have about it. Good quality and freshness.
