One of the better flavors

I would have to say this bar is one of the better Big 100 flavors. Nice PB taste with a salty finish. Has some pretzels bits on the top as well as a bonus. Perfect for post workout food.

Taste on point

Product was amazing looked good to with the pretzels on top... A little big and full of calories for anyone trying to lean but then just eat half

Blown away at how awesome it was. Flavor was good but man was it filling!!! 3/4 of the way through I started wondering if I was gonna finish it!

Great tasting

Awesome bar and great for a small meal replacement or a snack depending on your diet. Definitely nice to have a box around.

Satisfying Intra-workout Snack

I get insanely hungry on my long workouts. I ate this about 45 minutes in and it was so so satisfying. This is the absolute best protein bar I've ever had. Most protien bars are hard as bricks but this was perfect

great flavor loved this bar.

Filling and Delicious

These Met-rx bars are packed and big enough to supplement a meal or use as a big snack before a workout. Huge amount of protein and the flavor is amazing. Peanut Butter Pretzel is definitely my favorite. I'm very glad I received these in the January box. Already planning on buying them when i run out of the last sample flavor.

Great Tasting and Filling

This one might be a bit of a double edged sword. I thought that they were tasty and would just them before or after a workout only (due to the high sugar content). The good part is that they have favorable macros, the bad was that they are quite calorically dense. My goal is fat loss so I had to be careful when I added them, usually to replace a pre/post workout meal. Another good point is that they are quite filling, which is good for someone seeking fat loss. I can see how it might not be that favorable to someone looking to gain muscle as they do keep you full for quite a while, which might make it harder to reach those higher caloric requirements. All in all, I think that they can be used in both situations very well as long as the calories are taken into consideration. It's nice to review a protein bar and spend that much time talking about it's flexibility and only touch on the taste for a second because literally every flavor has been great. Also note, the sugar alcohol content is a little on the higher end so if one is more sensitive to the GI effects of those, that's another consideration to take.
