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*

ALLMAX IsoFlex is king!! I do know the price is somewhat higher than most brands out there for Protein Isolate, but the quality here and the taste is unmatched. The mixability of this powder is amazing. No stomach issues, no digestion problems. No problems whatsoever. Highly recommend it if you have the funds for it.*

I think the quality and purity of Isoflex is great. The caramel macchiato is pretty meh. Not too bad not too good. Think of a weak gas station cappuccino. But this is expected since it doesn’t have any sugar. *

One of the best I have ever purchased. The other protein which came close to this was Scitec Nutrition Iso Great. Mixes well and fast, no aftertaste, buy it if you can afford it.*

The chocolate is pretty good. It would probably taste even better with milk.  It also does what protein is supposed to do.... help build muscle! As many have said before it sure would be nice if the price was a little cheaper.*
