Review: Best protein mix I've had! - I really love this product. It's chocolaty, sweet, and mixes well. I use water, and often add powdered peanut butter for extra protein. Milk is good as well, if you can tolerate it. I use this mix to get my protein level up where it needs to be when I'm not able to get enough meat in. I love that I can make it the night before, and grab as needed when my blood sugar dips, or if I'm just a little hungry. It was approved by my oncologist and another DR, as well. Cost wise, it's not the most expensive, nor is it the cheapest. But you get what you pay for, and this is totally worth it. 🥰

### ⭐⭐⭐⭐⭐ Best protein powder
*by S***N on December 10, 2025*

Mmmmmm this chocolate is BANGIN!!! I highly recommend buying this stuff. Or don’t…more for me

### ⭐⭐⭐⭐ Not Bad For The Price
*by C***8 on April 20, 2026*

I prefer Gold Standard, but the cost of theirs has gotten to be too much, so I took a chance with Syntrax. The "Perfect Chocolate" is not what I deem "perfect" chocolate... more like a Mocha Chocolate flavor - but still quite nice. No nasty aftertaste and very smooth flavoring. Mixed well in my Vitamix. It doesn't keep me as full as my G.S. Casein does, but at the lower price I can deal with that.
