  • 10 Vanilla Ice Cream

Normally Chocolate is my go to flavor choice, but tried the Vanilla for a change of pace. Mixed with OJ for an Orange Julius type drink or mixed with non-fat milk, oatmeal and berries for overnight oats. Tastes great!

This is my go to protein. Ever since I first tried syntha 6 I have never looked for another. I like all their flavors but the chocolate peanut butter is my number 1. When I can mix a protein with water and still enjoy what I’m drinking. You know it’s good

Easily the best tasting protein on the market. I actually look forward to drinking it. The downside is the massive gas and upset stomach it causes me. It may just be my stomach but this stuff is like a **** bomb waiting to happen.

The cold stone Berry Berry Berry Good has a disgusting taste. When I open the container I thought I had boll weevils. The blueberries I think they were never dissolved. I two bought containers because it was a new flavor. Now there in the garbage. 🤮

Seriously Syntha-6? You're supposed to be making wholesome meal replacements with the protein powder--instead you're peddling garbage called: "High Fructose Corn Syrup." Look elsewhere if you're serious about the gym and staying healthy.

  • 10 Birthday Cake Remix

Wow, BSN did it again! I've never met a Syntha-6 I didn't like, and the Birthday Cake Remix is no exception! It somehow tastes pretty similar to melted ice cream, and doesn't have any weird aftertastes. It even has colorful sprinkles in it! It's easy to mix (I use it in milk and water), easy to drink, and easy on the stomach. I've tried at least 10 other brands of protein and this continues to be my favorite. I highly recommend this!

  • 10 Chocolate Milkshake

WE love BSN products! My wife and I workout together six mornings a week and we always look for products we can use together and get solid results. BSN Syntha-6 is one of those products. My wife loves the lean aspect of BSN Syntha-6 and I am a fan of everything BSN Syntha-6 does for me. WE love the chocolate milkshake & vanilla milkshake but not as much as the chocolate milkshake.

What can I say about Syntha-6 that hasn't already been said? Everyone has tried it or at least heard of it. A classic protein known for great taste.

  • 1 Birthday Cake Remix

I hoped this protein would be fun to drink and a little bit of cheat considering its ingredient label - High calorie, high carb, high cholesterol, high price NOT WORTH IT! The flavor is too bland, watery, almost no flavor and it has Birthday cake sprinkles inside which are unpleasant to drink. I literally want my wasted money back. Tons of other good quality protein manufacturers.
