By far the worst tasting protein I've ever had. Super chalky and fake tasting, plus awful chemical smell. Switched from ISO100 to save some money, but never again - at least not with this flavor.

Syntha 6 Mint Chocolate Chip is the best tasting Protein powder I've ever had in my life and I've had a lot of protein powder. The Syntha 6 Strawberry Milkshake was my previous favorite. I also notice more muscle on my body when I take it. Please never stop making this flavor!!

Used to love this stuff. After a year drinking others I bought a new tub, it just tasted off. The formula has definitely changed. It wasn’t as desirable to me.

Dont let the smell get to you. I was overly excited when I received the package. Opened it and got a whiff of ice cream until I tasted it... Flavor is just straight garbage. Very chalky and no flavor whatsoever. Can't taste the Cookie nor Doughnuts.

  • 10 Vanilla Ice Cream

Vanilla is always my go to but I decided to switch it up and try peanut butter cookie and wow I was blown away. It literally tastes like a peanut butter milkshake. I would highly recommend this product to anyone looking for something that is great in taste and price!

The greatest generous gift from BSN! ... 1 bar.. plus sugar, Sunflower "creamer" , emulsifiers, cholesterol and other muck as a bonus. gluten, lactose and gmo complement the bouquet ... I have used this more than once, hoping to find change.

I use this in the morning for early workouts and then eat breakfast afterwards. The powder mixes very well, rich and creamy flavor, and nice protein blend for absorption. Not the best choice if you are looking for low cal and low carb but otherwise it's great.

  • 10 Berry Berry Berry Good

The Berry is a mixed berry flavor and I love it! Blueberry, strawberry, raspberry...nice mix. For a little more "berry" kick, blend it with more of your favorite berries. Great for making berry protein pancakes. The Mint Mint Chocolate is more minty than chocolate, but excellent.Mixes easily and tastes terrific. I mix some up cold, then add it to hot cocoa for a warm protein snack.
