Customer Reviews
Decent bars, shipping could be faster
I tried the Variety Pack to get a feel for Zentein's protein bars. Most of the flavors were pretty good, especially the Peanut Butter. The bars felt substantial and helped with satiety. The website was easy enough to use, no real issues there. My order took about 8 days to arrive in New York, which felt a little long for a US shipment, but it wasn't terrible. Packaging was fine. Overall, a solid product, but shipping speed could use a bump.
Love the mint chocolate bar
So I was looking for some new protein bars and my friend told me about Zentein. I decided to get the Mint Chocolate Protein Bar. It arrived pretty quick, like, under a week, which was cool. The bar itself was actually really good! It didn't have that weird protein taste some bars do. I usually eat them after my workouts and they keep me full for a while. The price was okay, not super cheap but not crazy expensive either for what you get. I'd probably order these again when I run out.
Good bars, quick shipping
I ordered the Dark Chocolate Sea Salt Protein Bar. It tasted pretty good, not too sweet. Shipping was fast too. Got them in about 5 days, which was nice.
