Taste is great and mixes well. I will continue to buy. The Stawberry Milkshake tastes like melted strawberry ice cream.

I normally go with cookies and cream, but I wanted to try something different. It was between the Mint Mint chocolate chip or the cinnamon bun flavor. Well I should of went with the cinnamon flavor. The mint is horrible! It’s bland, has very little mint flavor and as a matter of fact it has really no flavor at all. Don’t waste your money!

The consistency, look, and even taste is similar to the original milkshake flavor. If I didn't know any better, I would have though I just purchased the original chocolate milkshake flavor. But it mixes great and I'm a bit disappointed in the flavor profile because I had high expectations for it. Overall still a great tasting product.

Syntha-6 chocolate milkshake tastes great. That being said, this product is garbage! It is only around 47% protein... stop wasting your money on this product and purchase a high quality protein powder. Way better choices out there than this.

  • 10 Peanut Butter Cookie

These flavors are absolutely CRAZY! I feel like it 12/10 would be a much more accurate rating! Over the years I have tasted many, many protein powders: JYM, Gold Standard, GAT, Kaged Muscle, Nitro-Tech and many more. Syntha-6 Protein Powder is by FAAAAR the best tasting and best mixing out there and who can complain about 10 grams EAAs! What I really like about Syntha-6 is that it is a protein "blend",meaning I can drink it after an intense weight session, after I wake up, before bed, after cardio, etc... I will defiantly buy more once my 3 tubs are finished

I really like this brand most of the flavors I tried are really delicious. My favorites being vanilla, peanut butter cookie! I absolutely hate the cinnamon bun and the cold stone mint chip is weak flavored.

Peanut butter is by far the best protein I've ever tasted for authentic and consistent flavor. Cake batter is a little more versatile (taste like a chocolate malt type of flavor), and cinnamon bun just taste like garbage. It's got all the right flavors, just not the right amount. Semi spicy cinnamon with a way too heavy dose of artificial sweetener.

Every flavor I've tried of Syntha-6 has been amazing. It's the only brand I can confidently say tastes amazing even in water, although I use milk most of the time anyways. Pumpkin Pie and PB Cookie are especially amazing. Really want to try Candy Cane! BSN products are quickly becoming my favorites, I drink the Endo Rush RTD's all the time as well.

I have definitely found my favorite brand/flavors of protein powder. I have tried numerous other flavors and find the taste, consistency and ease of mixing is excellent. I mix my shakes with 8 ounces of 2% milk twice and day. I am definitely sold on the BSN SYNTHA-6 brand.

A great product! I wish we got more protein out of it though. The Mint Mint Chocolate chip flavor was decent, nothing like the ice cream but the Germanchokolatekake was AMAZING! the best tasting protein I've ever had and trust me I've tried almost every company.
