This protein doesn't mix great, always ends up with some clumps. If you like mixing protein with water, this one is not for you. Tastes good with milk, but does have a very thick consistency. After I got used to the taste, it's actually really good, the first time tasting I thought it was gross. But if your looking for a low calorie protein this one may serve you well.

Met-Rx Protein Plus is an effective protein powder that provides energy and endurance needed for hardcore workouts that result in lean muscle. By far this blend of whey and casein is one of the best protein powders that helps produce real results.

I had a friend recommend this product to me b/c I was clueless about protein. I loved this protein. Easy to mix and tastes good too!!

I like the taste and that it mixes well, isn't to thick or chalky, and doesn't have that fake sugar flavor like many brands. The only thing I dislike is it's so frothy, the foam takes up half the shaker

Hands down best protein product for me and I strictly use this for my morning shakes and have since about 2013. Protein that blends so nicely it's like chalk in ur hand! Anyhow besides amazing taste, AMAZING! U can even add ginger, spinach, beets, garlic or whatever u like then drop MetRX Protein plus in and it makes very thing taste great. Results are what matter though and I am very pleased to literally see results almost daily now as I'm obsessed with gym and it's not a complete workout without MetRX!!!! I'll buy forever and I have this habit of buying it at trader joes do I may be paying more than I should at 24.99 for 20 servings but that's at 1 scoop, I add 2 scoops for 46 grams of protein do I only get 10 shakes out of it for that amount it's really expensive but can't see myself without it. Well budget is getting tight so I may have to shop online.

MET-Rx Protein 51 Plus is an excellent supplement for individuals, particularly those on a Ketogenic Diet looking for low calories, high protein grams and low carb grams solution. The price in comparison with other similar products is fantastic. The product though needs some real refrigeration prior to use to make it a bit more palatable as otherwise it may taste more nutritionally medicinal than nutritionally tasty. I would definitely it as a strong replacement meal or post-cardio workout drink.

I purchased Met-Rx from Trader Joe's and though it isn't my favorite it has met my needs as a replacement. It tastes like Vanilla. Therefore I can't complain about the taste. It is slightly chalky, and very thick. If you decide to throw some berries in this drink you'd better add some more beverage to it. I mix it with a Magic Bullet Deluxe blender with Coconut milk, and it mixes well. Don't bother using a shaker cup. Though I have never tried to do so, I have enough experience with protein powders to know that it would be a bad idea. A plus for Protein Plus is that it has both whey and casein proteins. Therefore it can be taken in between meals, and before or after your workouts.

After my experience with the last protein powder (which was highly rated, btw), I was hesitant to try another. Found this one at Trader Joe, and I have to say, the taste is great - not so cloyingly sweet and artificial like most powders. I always mix with water or almond milk in a blender and it comes out thick and creamy. Adding cocoa powder makes a nice chocolate taste, and of course banana/peanut butter is the best.

Ran out of protein powder and bought this till my regular order came in. Doesn't mix perfectly with a blender bottle and isn't the best tasting but as far as recovery goes it seems to work fine. Using a blender and mixing with milk and other ingredients (i.e. peanut butter, bananas, yogurt) makes it perfectly acceptable.
