This is the best QUALITY and TASTEING protein on the market. The only reason why it's not a popular as ON whey or Dymatize is down to the cost. If you try this, you will agree that's it's the best tasting protein shake you've had. The only thing I struggle with is the money outlay (recently laid off). $64.99 is a lot to pay for it. But if you can afford it, get it, it's the best out there*

This protein powder was just ok in my opinion. Didn't taste BAD by any means, just nothing spectacular. That being said, it mixed well and had a nice thick texture. It's quite pricey and not really worth the cost.*

The Allmax Isoflex peanut butter chocolate flavor seriously tastes better than a lot of milkshakes. It has little chocolate bits that taste amazing. If you use this mixed with oatmeal and almonds you have a nice slush dessert. Then only thing I score this bad on is price. If this protein was around 40-45 bucks I'd score it 5 stars*

Clean! And the unflavored truly is unflavored. I had only had a sample of Isoflex before. But now drinking it regularly it’s definitely great protein.*

This isn't what it once was. AllMax was one of my favorite brands. And Isoflex was there go to product. But somewhat recently they changed the ingredients and it really shows. It is now hard to get down. It taste bad as well as has a chemical taste. The profile for the most part is still solid, you still get 27 grams of protein in a 30 gram serving. So that's why it still gets three-stars but this use to be a five-star product!*
