Allmax Isoflex

Allmax Isoflex is a very expensive but delicious whey isolate. It digests very easy and the flavoring is top notch. If you have some money grab the chocolate peanut butter which is truly delicious. One of my favorite isolate protein powders on the market.


Best quality and product

I have been training for over five years . There are many and I mean many isoprotien I have tried. A personal trainer friend told me about this product. I have stayed with this product since. It is bit pricey. But its soo worth it. I has a great taste and no after taste. My favorite is chocolate peanut butter. I hope this helps someone. My kids have even loved taking this protein as well. That's a bonus !!!


Da bomb

I have songs tried the Strawberry and the Chocolate peanut butter. This stuff doesn't take long to dissolve, none of that clumpy junk. Great protein content per scoop. Yet the flavor doesn't suffer by any means. Best tasting protein powder I have ever had the privilege of ingesting.


good protein but expensive

This Allmax Isoflex is good protein but you will pay for it. I would probably try to buy this when there is a promotion on it or something like that, because it can be a little costly if you are buying it on just a regular day. However, you are not paying for something that does not taste good or does not work. This protein does have good taste and will provide your muscles with some great fuel to help aid in the process of recovery. It will not fail you.


Good, but pricey

Isoflex is definitely a good product. There is really only one downside, and that is the price. It's about one pound for over $20, and that's just too much for me. However, this website is one of the cheapest prices I have seen. I would probably go with the other Allmax whey protein because its cheaper, but this one is definitely effective.


A+ Product

Overall this Isoflex is a really high quality protein.. You pay a little more for it.. It is by far the highest quality and best protein thus far.. I would definitely recommend it..


taste is okay, results= extreme

Isoflex is by far the best protein I have ever had as far as muscle building goes. Ive been lifting intensely for about 1.5 years now and have had many different types of proteins and ALLMAX peanut butter chocolate blows any protein Ive ever had out of the water when going for the result of lean mass building. Being an Isolate, its got zero sugars, no fat, no cholesterol, next to no carbs, the least amount of calories and the most protein per serving. It may be a little pricey but you get what you pay for and its worth every penny. It mixes great and taste is about an 8. Highly recommended.



Almax Isoflex is a pure Isolate, which is pretty much meaningless. BUT, this is an awesome tasting protein and mixes incredibly well. just be aware that, as it is an isolate, it mixes really thin. Only useful for a shake, which I hardly ever have (preferring to make things out of my protein). If you are looking for an isolate though, this is a solid choice. Recommended.
