  • 6 Mint Mint Chocolate Chocolate Chip

Overall the product is great for what you need. However, the mint chocolate chip does not taste great with water in my opinion. I don't like adding milk to my protein shakes to avoid the added fat and calories, but for this flavor that's the only option you have to make it taste good.

  • 9 Birthday Cake Remix

I love Syntha 6 and have been using it for 2 years on and off now. When taking right I can feel and see the difference. Nothing beats the taste of it too. By taking it right, that means using it twice per day. I've been stacking it with KM isolate in the morning. So immediately after working out, I take km isolate, then I wait 15-30 minutes and take Syntha. It gives me the all day amino coverage that I love. Plus the tastes are amazing. I then take a scoop of Syntha at night before bed. Chocolate cake batter is their best flavor. The birthday cake Remix is amazing too, but it's not as thick and they put too many sprinkles in it. They just sink to the bottom so you get a ton of sprinkles in your last sip. Chocolate milkshake is good but if your a chocolate fan, chocolate cake batted is 10x better. Love this stuff!

  • 10 Birthday Cake Remix

My prayers have been answered! I bought Syntha6 Birthday Cake Remix at a local store and the taste is nothing short of amazing. This will improve to a 10 once they make the isolate version. My only issue with Syntha6 is since it is a concentrate and has some filler, it does cause a bit of gas (particularly when first starting). I don’t care though with a flavor that good haha. The price is also great. I just bought 2 big tubs here to stock up while on sale.

  • 9 Chocolate Milkshake

Best tasting protein powder I’ve ever had, includes effective ammount of protein and fairly good price. Also the scoop thing never gets sticky or covered with the protein powder and I have no clue how, it amazes me

  • 10 Strawberry Milkshake
  • 10 Vanilla Ice Cream

I sampled this in the vanilla ice cream a couple of times and was really impressed. I do not drink milk but mixed in the blender with water and ice. it tasted just like a milkshake. Based on reviews I decided to buy the strawberry milkshake flavor as well. Since ice cream is one of my biggest weaknesses i thought this may help me stay on track this summer. I love both flavors.

Where’s the FIBER ? Does this contain 0 grams of fiber now ? I use to buy instead of other brands because it contained 5 grams of added fiber


High fructose corn syrup is not good there are many other ingredients you are paying more for fillers and less for protein
