So I have tried a lot of different protein powders over the years. The only one I found that tasted better was the original Cytosport Monster Mass but they reformulated it and it now has more of that classic " tastes like a protein powder". To be fair, protein powders have come a long way from the chalky days and there are others that are okay. I look at it this way: everything else being equal, is this something I am going to look forward to drinking? At the end of the day what counts is consistently fueling your body and if you don't look forward to drinking your protein, just makes it a little harder to stay on track in the long run.

I would not describe this flavor as Berry Berry Berry Good as it is overwhelmingly too sweet and doesn't taste anything like Berry.

I tried this protein powder cause it had all the other different proteins in it. Peanut butter cookie tastes just like a real one. I love it will have to reorder this! Good taste and mixes well.

Tastes great! Only thing that is a bit concerning is the amount of cholesterol in a scoop. Some better options out there without having to sacrifice heart health.

The best thing I’ve ever tasted! Cannot even believe there’s 22g in one scoop! Just seems like it’s a reg shake. I’ve never been this fan of a protein shake.

To the comment below saying I should do my research. First off, I’m well aware that this is a blend and a not pure whey powder. I’m also aware of the amino spiking done to raise the protein amount. Still doesn’t justify yielding around 47% protein. People are buying 5 pound containers thinking they’re getting 4-5lbs of protein when in actuality they’re getting a little over 2lbs. Again, as far as taste, this protein is great!! Very good flavor. Just pointing out there are MUCH HIGHER QUALITY products out there. But to each their own. It’s your money, spend it how you wish...

Best tasting protein out there and and an EXCELlENT meal replacement shake. In response to the comment below calling this protein garbage because of the protein content he should probably do some more research. This is NOT a 100% whey product and should not be treated as such. It is Syntha6 because it has 6 different types of protein that break down at different rates giving excellent absorbtion over a few hours as opposed to a straight whey product. Also has dietary fiber which helps you stay full and digest as well as good quality carbs and MCT fats to add nutrition. Every supplement is simply a tool, you just need to use it correctly so it can perform its job.

I have been using protein for a long time and even though this product may not have the highest protein content, you will never forget to take it. For penutbutter lovers the penut butter cookie is the best protein I've had. Vanilla ice cream tastes exactly like ice cream and the chocolate penut butter doesn't have that much of a penut butter flavor but it is still exceptional. Highly recommend this brand
