Mixes well and tastes good. I like the protein matrix so you get the immediate as well as time-delayed protein absorption. The Peanut Butter Cookie really tastes like peanut butter cookies. I look forward to trying the other flavors.

Hands down the best tasting protein powder on the market for the last several years. I have consumed these types of shakes for over 15 years and nothing has come close to the taste, macro nutrients and mix-ability. You will enjoy drinking these shakes unlike most of the competition.

I've tried several proteins including Nitrotech, EVL stacked protein, ALLMAX whey classic and several others and BSN syntha6 has consistently been my go to protein over all the others because it works best for me. I seem to feel better an have more energy while taking it. I take 4 scoops a day spread out. I love the carb to protein ratio it has. My favorite flavor is the strawberry milkshake because it reminds me of the Nesquik strawberry milk that I love. I would highly recommend this to everyone.

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.
