I won a 40 pack of this stuff in a contest and I thought, what the heck? Why waste it? So, even though the flavor (cake batter) wasn't that great, I enjoyed the shake. After a week or so of having a shake a day (to which I added a handfull of frozen mixed berries) I started to feel better ~ kinda' pumped up. After a couple of weeks my physical therapy began to take off in effectiveness.
You see, I have had chronic back problems for the last 10 years or so and had been through surgery, etc. and was continuing a program of phys. therapy to keep trying to get off the pain pills.
Well, I could feel the support trunk muscles growing, getting stronger and my back is hurting less and less and the vicadins are getting fewer and fewer. Plus I feel a lot better overall and have lost weight! Go figure. I'm not doing any weight lifting, just the physical therapy exercises and isometrics during the day but I can feel the muscle mass and my therapist is really impressed as well.
I will add that I am a 58 year old male & I've read that protein supplements are helpful as we age.
I would have never have tried this stuff if I hadn't won that first box but, what a stroke of luck that was.
Also, the chocolate is WAY BETTER a flavor and goes very well w/the berries I like to add.

I've tried just about every way to mix this product. If you are in a rush get about 6-8oz. of hot water in a shaker bottle with a mixing ball. Shake it until its dissolved. Then add cold water and ice to cool it back down. Also, you cannot add the entire pack at once. Pour in about a 1/3rd and mix, pour in the second 1/3rd mix again, then pour in the last of it and shake for one last time. YOU CANNOT USE 16-21oz. of water, it'll be too thick. Blending it in the same fashion seemes to work best (if you have time). It taste really good and if you add ice you'll have a milkshake. I use to add a bannana but now I just drink it straight up. As a note, when you blend it for too long it begins to get a little frothy, but I tend to like it that way. I've been using it for a couple of weeks now and have lost 4-5lbs. while working out. Took last week off due to work. Think about it 240 calories to fill full for a while (or you can buy a candy bar and still be hungry). I'm on auto delivery and past out packets to friends who wonder about it.

I'm a believer. I just ordered another box so that when my 40 are out I won't be interrupted. Just got these and have been drinking one each morning for breakfast for pretty much the past month. In the past four weeks, I've lost 28 lbs (258 to 229). No lie. It's unbelievable how they fill me up and taste great. A packet makes a ton too! I use my magic bullet, and blend the whole packet with about a cup of ice with two cups of water, and it turns into a delicious breakfast chocolate milkshake. The taste is not just tolerable, but great. I like the flavor. It doesn't taste like a lot of those breakfast shake chocolate flavors, where you immediately get hit by the artificial sugar or the chocolate doesn't really taste like chocolate. Yum!

Having been a competitive swimmer for ten years before playing waterpolo in college, I'm highly experienced with athletic nutrition- I actually used to blend my own protein from a base of Pro-Bolic, but since they reformulated a few years ago I started looking for something better. Obviously I'd always known about MetRx, but now that a case of this stuff costs only a couple bucks more than proteins I was previously blending, its a no-brainer.

There are powders with slightly better globulin spreads, and there are powders with slightly better vitamin spreads, but at this price point ($54/case) its difficult to find a solution that beats this stuff in overall quality and consistency.

Three favorite ways to ingest:
Half packet mixed with bowl of oatmeal and 1 tablespoon of chia seed
Full packet mixed with just under 16oz of water; this basically creates a pudding.
Full packet mixed with a quart of water, consumed during long workouts.

Great, convenient, a perfect mate for a BlenderBottle.

Tastes good, and is easy portion control or a quick fuel-up after a hard workout without having to cook or have meals prepared. The taste is better than "palatable," it's actually decent. But to me the vanilla is even better -- it actually tastes like a treat.

A Blender Bottle works perfectly with it -- put in enough water to cover the ball first, then the powder, then the rest of the water. Then put the lid on tightly and shake. It blends very nicely, with no large powdery clumps.

These shakes are really thick... The flavor is great and they definitely keep you feeling satisfied/full for at least a couple of hours but if you follow the instructions as written on the package and use only the 16-20oz be prepared for a drink so thick you may need a spoon. The directions do say to add or subtract water for desired consistency so I've gone up as high as 32oz trying to figure out what worked best for me. At 32oz it was a bit tough to power down the whole thing so I ended up having to split it in half and drink half later which did not keep me as full as long.

If you can find the right amount of water to get these shakes to a consistency you like though they are pretty good. The flavor is one of the better chocolate powdered shakes that I've come across so far.
