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.

I’ve been drinking Syntha-6 on and off since 2012 and have cumulatively consumed more than 200lbs of this protein powder over this time period. My personal list of favorites after ~7 years with BSN: 1. Strawberry Milkshake 2. Birthday Cake Remix 3. Chocolate Cake Batter 4. Peanut Butter Cookie 5. Vanilla Ice Cream My biggest go-to is the strawberry milkshake because it has a lighter flavor profile that doesn’t overwhelm you. I can drink it any time of the day, even early in the morning and it’s great. Chocolate cake batter is hands down the best chocolate flavor protein drink I’ve ever had. Peanut butter cookie is the best peanut butter flavoring I’ve found so far. It hits a balance between being really “peanut butter-y” without becoming too strong and gross to taste. Finally, Vanilla Ice Cream, is a great easy taste. It’s low intensity and is great if you ever want to mix it in a blender with other items like berries or fruits. Worth noting is that only 1 of the “cold stone creamery series” flavors made it on my top 5. These “cold stone creamery” flavors are very different from the usual Syntha-6. They are far richer and taste nothing like protein powder. It’s like a **** desert in a bottle, whereas others may taste like treats but they still are clearly protein powder. The improvement that they’ve managed with this Birthday Cake flavor just shocks me. Specifically with the birthday cake flavors some people won’t like it, the sprinkles are little gimmicky, but I find it incredible. I use 2 scoops birthday cake remix + 30oz of skim milk as “cheat meal” when I’m craving something sweet. It really is that good. The German chocolate cake “cold stone creamery” flavor (that I can’t spell) misses the mark. It’s just far too sweet and overpowering. It’s still a great flavor when you compare it to other protein brands on the market, but it does not compare to some of BSN’s other offerings. In summation, BSN’s Syntha-6 is the best protein I’ve ever bought. You know why? Because IT TASTES GOOD. It may have a few more grams of carbs and sugars that others lack but that doesn’t matter. If a protein doesn’t taste good then nobody drinks it and it sits on your kitchen counter for 3 months. Syntha-6 gives me something I know I can incorporate into my diet and rotate through enough flavors to keep it interesting.

BSN is advertising "New Look Same Syntha". However the product label says something different. The old chocolate milkshake Syntha 6 had 5 grams of fiber and 2 grams of sugar. The new chocolate milkshake Syntha 6 has only 1 gram of fiber and 3 grams of sugar. I noticed that did not have the nutrition facts for this product. They should not sell this product without warning people that the "New Look Same Syntha" advertising is false. I would not have made my most recent purchase if I had known the product changed.

These new cold stone flavors are horrible. Always been a big fan of syntha-6's product. Cinnamon Bun is one the best proteins I've ever tasted over the years, but these new cold stone flavors are awful. Don't waste your time with them. The birthday cake one tastes like vanilla with sprinkles in it. Except in the Louisiana heat they just melt along the side of your protein shaker and are extra work to wash out of your shaker. And cause of their weight, the sprinkles that don't melt into your shaker all sink to the bottom and you don't taste them till the last sip where you get an overload of sprinkles at one time. Germanchokolatekake, is nothing impressive either, just do yourself a favor and get the regular chocolate, it's far superior. Still stand by Cinnamon Bun as one of the best all round proteins I've ever had. They need to sell that in the 5 lb options.

Shouldn't be listed as casein. It's a garbage blend cut with aminos to cheapen. I feel like an idiot for buying this

The calorie content is a little higher compared to more pure protein products, but it's well worth it. It tastes amazing, and no feeling bloated like you do with whey isolates.

Mixed with milk it really is an awesome strawberry milkshake. I usually mix with water though and it dissolves really well and still tastes great. I highly recommend this protein to everyone.
