Review: Five stars for what it is, not for what you might want it to be. This stuff does not taste good by itself. It just doesn't. Don't expect it to taste great by itself - it's just casein protein. Over time, you will get used to the taste if you drink it often enough. If you feel so inclined as to make a big smoothie or something before bed, go for it, but I am just trying to maintain/build muscle while I sleep without adding a lot of other calories; so, I just mix it with water in a shaker bottle about a half hour before bed. It's a little chalky; so, don't expect the same texture as whey, but it mixes fine - I shake it 20-30 seconds typically. I haven't noticed any digestive issues, per se, but it does what it purports to do: clots in your stomach for a slow release of protein. Want to get a glimpse of it? Try shaking it up in a shaker with just water and put it in the fridge for an hour or two. When you take it out, you will wonder if you poured casein or concrete into your shaker. This makes it a GREAT supplement for a protein "ice cream" that I will make from time to time. Take 4 frozen bananas, an avocado, 2 scoops of casein, 2-4 scoops of your favorite flavored whey -- I use Promix Raw Chocolate -- .5-1C milk or almond milk (more liquid depending on how much powder you use), and blend. You will have soft serve immediately that keeps you full and a lot leftover for later in the week,
Review: Trying this for the first time. I have been using a similar product made by Muscle Feast. I noticed that the prices of both promix and muscle feast are volatile. I measure, using the one time purchase price, how much I'm paying per gram of protein instead of per ounce and today the difference is $.0012 in promix favor. So after 10 grams of protein, you save a penny. Doesn't seem like much, but over time, it will add up. I believe both brands are quality casein proteins. Differences between the two: Promix color is more light brownish in color, Promix clumps to the side of the scoop and I have to bang it against my smoothie container to get it out of the scoop. Both mix well and I don't detect any taste with the unflavored versions.

Unflavored is exactly as it should be. Unaltered sweetness or flavor. Mixed easily. Nice and thick of using only a little water.
