Great flavor and texture
If I were to eat this without knowing it was a 'protein bar' I would never know. Great texture and flavor. Nice and mild, not overly sweet.

Love these! Seriously the best tasting & looking & smelling protein bar on the market! It taste like a rice crispy treat but better! It's great on carbs and protein & super filling! Love the flavor so much that I just ordered the vanilla marshmallow & chocolate flavor one!

Love it
I've only tried the salted caramel pretzel and the chocolate crunch. Both are really good. If I had to pick one or the other, I would probably go with salted caramel. The sweetness is similar to the powder.

Delicious, crisp and filling
The taste of these protein bars is exceptional. They are light and crispy and the chocolate is delicious. These are thicker than any protein bar I have ever tried. These are really a mouthful! If they would lower the price I would buy them by the case.

The best protein bars out there
I have tried a lot of protein bars over the past 3 years and this one is the very best one on the market today in my opinion. They taste good and they satisfy those in between meal hunger craves. I was sold on the Quest bars for a couple of years until I tried a few of these Syntha-6 Protein Crisp bars from GNC .

Syntha Did It AGAIN!
As a fan on the Syntha-6 protein, I was interested in trying this protein crisp. I tried the Vanilla Marshmallow. I seriously felt like I was eating a Rice Crispy treat that wasn't messy or gooey. Killed the sweet tooth I tent to have. No chalky feeling in my mouth or funny after taste. I strongly recommend this product.
My only con is that the carbs are a little high at 23 for a low carb plan.
