It's Just!100% Casein Protein Powder, Made in USA, One Ingredient, Slow Burning, Time Release, 6.9g BCAAs, 1g Carb, Non-GMO (Unflavored, 3lbs/48oz)

This works terrifically for long-term protein.I gave it 5 stars for flavor, even though some people complain, because here's the thing: It's "its just" brand, it's JUST PROTEIN. No flavors, no sweeteners, JUST PROTEIN... which in pure form doesn't taste terribly great. You can't expect this to taste like cookies and cream, vanilla, or chocolate. It tastes exactly like what it is... JUST protein.

It's protein powder. It doesn't upset my stomach like the ones with fake sugars. It's a great price for 5 pounds of protein. I mix it with fruit in smoothies with milk and yogurt and it tastes great! Super easy.

Though unflavored, it has a decent taste to it. Mixes well without lumps. Taste is better than some flavored casein powders I've bought. I was thrilled to find this powder in a large container size. Protein quality seems good.

Do not buy. Requires a massive serving scoop and still needs to be mixed to drink. Bag arrived busted because of how thin it is, covering everything else in the box making a massive mess when the box was opened. Has no taste and considering how much has to be mixed it is a waste of money as there are more efficient and effective casein supplements out there.

Don't mind the bad reviews, they are not about he protein but about the releaseability of the bag they use, the product itself is pretty much flawless for the dietary needs you want.

My doctor wants me to take this stuff because old people like me need to maintain their muscle mass. He also wants me to exercise, which I do, some. So I'm not qualified by knowledge or experience to say anything about how effective this stuff is. But my son, a long-time weightlifter, knows about using this & it's the brand he recommended to me. Hence, five stars.But given my diet, the only effective way for me to ingest it is by drinking it. And it's not an easy task, because it gets chalky, clumps up, and besides, I hate milk. So here's how I make it drinkable. The sequence is important.METHOD:1. Pour 8 oz of cold water into a glass or blender or shaker. Add one teaspoon of basic cocoa. Mix it up with the spoon.2. Add one teaspoon of olive oil & stir. This is the critical ingredient.3. Add 1 scoop of the Casein & stir in, but don't worry about blending. You just want to get the stuff mixed into the water.4. At this point, use some kind of blender & blend till the drink is smooth enough to suit you. This won't take long and it will get smooth enough to drink pretty quickly.OBSERVATIONS:1. The olive oil is critical. It doesn't have to be anything special but you might want to get something that doesn't have a robust flavor. I use Pompeian Organic Extra Virgin Smooth because I've been taking a tablespoon a day of it already, so it was available. I might try using a tablespoon of it instead of the teaspoon I'm using in the mix. And I'm going to try a cheaper brand if that seems to work.2. I use Hershey's Special Dark Cocoa - it's powdered & has no sugar since I'm diabetic. But you should be able to use anything you want along these lines to flavor the stuff. Or if the taste is not an issue, just use the olive oil.3. I use a small hand held battery powered milk frother for the blending. It is what I use to froth milk for cappuccinos & not very big - nothing like an immersion blender. But you could use a regular blender for the whole process, except it leaves a blender to clean up. Or a hand held protein powder shaker might work - or might not... or an old fashioned eggbeater...or an immersion blender. Whatever gets it to the texture you want.It's a YMMV situation - works for me!

Re-sealable mechanism doesn't work. I have to dump all the powder into Tupperware now? Annoying.

Let me be clear, the product itself is great. No issue with the product itself. It mixes well, and I like the fact that it has very few ingredients, but the "resealable bag" doesn't reseal. The first time I opened it, I fought to get the bag closed for 10 minutes and even then it wasn't completely closed. No matter what I did, the bag wouldn't close, so I had to end up using a empty protein container to pour the rest into and ended up getting powder all over the counter, myself, and the floor because this powder is so fine, it just gets everywhere. Don't get me wrong, I get a plastic resealing bag is cheaper than a plastic container which saves money on their bottom line, which means a cheaper sale for me. I completely respect that. I'm not saying this company is bad and that no one should buy from them, the product is great, but my friendly advice to this company is to look into a better ziplock feature for the bag itself.Update: purchased a second bag hoping that perhaps the first was just a faulty bag. Same thing happened as before. Wouldn't reseal, had to put the rest into a empty protein container and small Tupperware container. Got powder all over the kitchen counter, the stove, myself, the outside of the protein container and the floor. It them took time to clean all of this up of course. I won't be buying this product again. At least until they fix this issue. Which is a shame really, because the product is great (and is probably the healthiest casein on the market), but I shouldn't have to worry about transferring the powder to another container once I open a bag every time.
