    * I love the taste of this protein powder. Chocolatey without being overpowering. One star short because it leaves a few lumps when using a shaker bottle.

    * This product was no where near as good as other brands. Perhaps mixed with milk it would be better, but mixed with water it had a bad aftertaste and was not something I'd drink by choice.

    * It's ok, but has a slight chemical taste that I found off-putting after having enjoyed other brand's shakes instead. This doesn't compare favorably.

    * This is by far the best protein AND value I've had yet. I am especially impressed with how well this mixes when I want a THICK shake. I add a ton of ice and a pinch of water then blast it in my nutribullet. This thing is thick and perfectly blended. I thought other proteins were terrible until I realized they needed to be blended water thin. Whenever I have my bodytech or eas thin shake, I think about how much I loved the thick matrix shake.

    * This is a tad higher in carbs than I like, but worth it! It is so good! Several others on lowcarbfriends have also tried plenty of protein powders with unenthusiastic reports, then loved this one.

    * This is, hands down, the BEST protein shake I have ever tasted! I buy several bags at a time and I almost don't want to tell you how great it is because I'm afraid there will be none left for me! I will purposely not eat a meal (sometimes...) just because I know how delicious this stuff is and I would rather have it instead! It is FANTASTIC!

    * This product is great cold or the chocolate or vanilla is good added to your morning coffee in place of cream and sweetener! It's creamy and delicious, low carb, and low calorie.

    * Cookies n cream is pretty delicious, even with water it's not bad. Although most of the 'cookies' settle to the bottom, I can't say that this really matters though. It does mix as easy as they say. The only real negative is the bag that the 5.0 comes in doesn't zip closed all the way after you open it but this definitely is not a reason to pass on ordering this protein.

    * This protein has a great taste and it lasts a long time. I got the Perfect Choc & Van for a morning shake and post work out. I feel as if both of these are a great protein in taste and quality.

    * I've found this to be the best Brand of protein shake out there!! It mixes easily in a shaker with ice. The Mint Cookie tastes great, and the Perfect Chocolate is even better with 2 tablespoons of PB2. Helps to keep me full all morning!!

    * I am a big fan of the Matrix Perfect Chocolate, it is my morning wake up drink of choice. I always drink it hot, and a little advice, mix it with a small amount of cold liquid (I use a hand emulsion mixer)then add your hot ingredient slowly stirring constantly. Makes a very smooth hot cocoa.

    * I love Matrix 5.0. Not only is it a great buy, but it's delicious and filling. The new Banana is my favorite, with the Strawberry close behind. YUMMY! It's helping me eat my protein and not eat what I shouldn't. I love Syntrax Products, they're the best and Netrition has great prices!

    * Excellent product. Bariatric pt., so I use alot of Protein powder. No real aftertaste, either SF related or 'fake' chocolate taste. Not bitter.

    I use it in my decaf coffee, and yogurt daily. For a lil punch with the coffee, I add a pinch of Nestle Dark Choc powder. And/or a couple of pumps of Davinci SF Creme De Menthe Flavoring syrup to taste.

    Works well coffee wise, Iced or hot. Best if you use a blender bottle or mixer. If hot, allow for pressure release when opening, or you may/can very well get wet. Especially true with blender bottle. Been there done that!

    * This product is perfectly named -- "Perfect Chocolate". I have found so many protein powders can be grainy and chalky and taste like...well, like chalk. Matrix is delicious, it mixes up instantly and is great by itself or as an added boost to a smoothie. LOVE this product!

    * Its pretty good (considering that it's a protein drink). It doesn't taste that great with just plain water, but it doesn't make you gag either, so its a pretty fair deal. You still have to mix it a lot, too. Overall, I'd say it's one of the best I've tried. My only complaint is that it's a bit high in fat for me....but given the taste of this brand, I would like to try the Nectars next time.

    * I have the Cookies N Cream and it tastes decadently good! Beats most of the other brands hands down! I use this as a protein shake, in baking L/C sweet breads, and cheesecakes. I think one needs a good shaker bottle for this one, to use as a protein shake anyway, as the "cookies" aspect tends to drift down to the bottom, so it does occasionally need a good shake now and again (but then again, so would Oreos). I think it will help make a great thick ice cream milkshake, will try it soon. YUM.

    * Good protein powder, recommended. A little hard to mix with a spoon, there always seem to be these little clumpy lumps that don't want to break up. Also, I just have to comment on the fact that the vanilla flavor tastes like banana. I have a feeling the chocolate and cookies and cream taste better. Guess I'll try those next.

    * I enjoy the taste, but more importantly I love the fact that you can just stir the Syntrax protein powders, i.e., you do not need to use a blender. This is especially helpful for anyone who wants to have a protein drink away from home. You can make them at work or anyplace else. All you need is a cold cup of water and a spoon to mix them. You can even put your scoop of powder in a small plastic bag at home and then put it in a cup in a remote location. The Matrix 5.0 Simply Vanilla mixes easily with flavors such as DaVinci Gourmet syrups (regular or sugar free).

    * Mixes well in water or milk. Very smooth. Great vanilla taste with a hint of banana. Good on its own, or use it as a base to add cocoa/fruit/etc. Very versatile.

    * This is a great tasting product that mixes well. Can be used with plain water so it is available anytime, anywhere. While the protein is not in the same league as products designed to build muscles, it is great for maintenance with a possible increase in muscle mass. Very decent product for the price. This is already my second order!

    * I've tried MANY protein powders, and this one is the only one that I've reordered. Taste is great and can be used instead of powdered milk (except at high temps - it tends to get grainy above 140 degrees).

    * This is one of the best protein powders that I have tasted, and I have tasted a lot! It mixes very easily and even tastes great with just plain water. It is definitely a winner of whey protein drinks.

    * I follow a very strict low carb diet. I use Marix 5.0 for breakfast every morning. It has helped me to lose weight and maintain. I contribute that to the product not having any maltodextrin (which raises blood sugar and causes hunger) and having three different proteins that stay with you longer (no hunger for a longer period of time). And it mixes and tastes great! Perfect Chocolate also gives me my chocolate 'fix' for the day. Great product/great price!

    2/5 October 20, 2006
    * As a protein this is an average product. One will not notice immense gains in strength or size, it acts more as a buffer to prevent muscle loss (catabolism) as most proteins do. However this protein does not mix well, even in a blender. This protein does not taste decent or "perfect" as it claims. When I opened up the bag the odor was foul, it honestly smelled like manure. The novelty of the bag wears off when you start getting to the bottom of the supply. Having to turn the bag upside down is not a pleasant experience. *Also pay attention to the BCAA profile on the side, the numbers seem very appealing until you read the fine print where it states that this profile is per 100 grams of protein, not the 20-25 gram typical serving.

    * This is the most economical product on netrition.com if you're interested in buying just pure moderate-release protein in bulk. The orange cream and chocolate taste pretty good, and the vanilla blends in with whatever flavors you mix in. Easy to mix most of the time, no bitter aftertaste of any sort.
