Review: Good stuff - Really like this protein powder will be reordering it. Taste is not sickeningly sweet and mixes in well. I use it in coffee my son usually puts it in milk and that’s good. He said do not mix with water—he did not like that combo.
Review: My favorite banana protein powder - I’m sad to see this item is no longer available because it has become my favorite protein powder. I love the packaging (I’m not a fan of the large canisters) which makes it easier to retrieve the product as you get closer to the bottom. The quality of the powder is noticeably better than those I’ve tried in the past. I enjoy the flavoring, mixability, and how easy it is to add to almost any breakfast dish or baked good.

### ⭐⭐⭐⭐⭐ Good stuff
*by M***H on May 21, 2026*

### ⭐⭐⭐⭐⭐ My favorite banana protein powder
*by R***. on October 28, 2022*

I’m sad to see this item is no longer available because it has become my favorite protein powder. I love the packaging (I’m not a fan of the large canisters) which makes it easier to retrieve the product as you get closer to the bottom.

### ⭐⭐⭐⭐ More “Banana Cake” Than Bananas & Cream
*by H***D on March 25, 2026*

Like other protein powders from Syntrax, the quality is solid. It mixes well, has a smooth texture, and performs as expected from a nutritional standpoint. The main differentiator here is the flavor. Despite the name, it doesn’t really taste like a classic bananas-and-cream profile. Instead, it comes across more like a banana cake -- slightly sweet, with a noticeable “baked” flavor. It’s not bad, but it does lean a bit artificial and may not match what some people expect from the label. For me, it’s good but not a top-tier flavor. I’d use it again if needed, but I’d choose other flavors (like Chocolate Supreme) first if they’re available. Overall, a solid protein powder with dependable performance, but the flavor is more niche than the name suggests.
