Best tasting protein on the market! To satisfy my nightly sweet tooth, I mix it with greek yogurt for some faux ice cream. I will never use another brand.

I would rate this lower if I could. This is one of the worst proteins in an already over-saturated market. BSN sells based on flavor and marketing alone, entirely forgoing quality. Just look at the label. The entire thing is an absolute joke. Less than half of the powder is actually protein. But what do you expect from a brand notorious for weakly formulated products with under-dosed ingredients and prop blends. Go buy something worth your money like Kaged muscle, Nutrabio or a number of other companies doing things the right way.

First off I have never mixed these with just straight water. First time I used Simply lactose free whole milk and it was too frothy. After that I mixed it with Silk 30 calorie unsweetened vanilla almond milk, 6 oz, and it's perfect. The mint one tastes just like a shake to me which is crazy but my wife says she can taste the protein a lot in that one. Also not over the top sweet. The birthday cake on the other hand, while still tasty, is extremely sweet. So I mix half a scoop of that with a half a scoop of BN flavorless whey protein and its perfect for me while the wife does it straight. Will definitely reorder after I run out in like 3 months since I got the MASSIVE containers. Oh and the shipment arrived on time which was nice too.

I have searched all my life for the perfect protein (results, flavor etc..etc..) and BSN Syntha-6 is it! This is the most delicious protein supplement I have ever tasted and it's not close. For a protein supplement to be this good and have great results is just awesome! I mix it with almond milk and it is like having a dessert. Just incredible! I have been using it for over six months now and I have tried other proteins and nothing comes close. I always have regrets after I buy them and for not buying BSN German Chocolate Cake. I have three 4.6lbs tubs in my cabinet and I will but this till it no longer exists (or I no longer exist).

How did the cookie dough one even get past quality control. The other flavours are good but avoid cookie dough at all costs.

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.
