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.

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!

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.

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.

Germanchokolatekake: one of the top 10 reasons to be re-incarnated. The other 9 reasons aren't important. Love the hint of coconut in it. Can't stop yumming in my head about it. Candy Cane: Who's the evil person at BSN who decided to make this limited edition? I want this year round! Did you know that Candy Cane Syntha-6 and 0% Skyr Icelandic Yogurt go together like copy & paste? Try it. Your taste buds will thank you. Salted Caramel: Why does this have a low rating? Who's taste buds are broken? OMG this is so delicious, I just licked the insides of my empty shaker cup so I could get another taste. When I drink this, I'm like a unicorn prancing through a field of platinum grass with Werther's Original Chewy Caramels shooting out its ***. Blend it with a banana... I dare you.

So I have tried a lot of different protein powders over the years. The only one I found that tasted better was the original Cytosport Monster Mass but they reformulated it and it now has more of that classic " tastes like a protein powder". To be fair, protein powders have come a long way from the chalky days and there are others that are okay. I look at it this way: everything else being equal, is this something I am going to look forward to drinking? At the end of the day what counts is consistently fueling your body and if you don't look forward to drinking your protein, just makes it a little harder to stay on track in the long run.
