HYBRID RATIO ISOLATE (HRI) – ION FILTRATION TECHNOLOGY
HRI Filtration Technology
BIOACTIVE FULL-SPECTRUM WHEY PROTEIN ISOLATE FRACTIONS
ALPHA-LACTALBUMIN
15% Higher than typical Whey Protein Isolates. Highly valued in baby formla as it is the primary Protein Fraction in Human milk.

ISOFLEX uses a unique protein extraction technology called Hybrid-Ratio Ion-Filtration (HRI). A hybrid of two isolate purification technologies incorporated at a specific ratio to produce a truly superior ultra-pure Whey Protein Isolate. Cutting-Edge HRI Technology allows ISOFLEX to retain an exceptionally high protein yield while maintaining enhanced bioactive whey fractions.

ISOFLEX contains absolutely NO Whey Concentrate. Concentrates have higher levels of fat and sugars with a lower percentage of protein and lower bioavailability than Isolates. While other brands use Concentrates, ISOFLEX users know that Isolates have a superior protein percentage and won't settle for non-Isolate blends.

That's right, 100% Whey Protein Isolate at your fingertips, giving you a whopping 90% protein content! With only Native and Intact, Non-Denatured Whey Protein Fractions. 27 g of Pure Protein that has been laboratory tested, certified and approved.

Truly Pure. Truly Superior.

If you're a bodybuilder you know that high levels of protein consumption are critical to success. Most aim for 1.5 to 3 grams of protein per pound of bodyweight daily depending on the intensity and frequency of their training and space their consumption throughout the day. We all know how important it is to get our protein in during that precious anabolic window.

Because of ISOFLEX's high quality pureness you get some of the fastest protein absorption out there with the ultimate amount of amino acids to balance it out. And don't forget ZERO fat and ZERO sugar! ISOFLEX mixes well in a shaker cup but can be combined with other ingredients in a blender as a smoothie too. Take ISOFLEX anytime and anywhere you need it.

Amazing taste for isolate protein. A Protein with pretty much O's down the nutrion label. This is pure whey isolate (not blend). By far no other compares to Allmax Nutrition Isoflex. I have tried many proteins and this one is beyond my Favorite. The Chocolate Peanut Butter is AMAZING!

Started out at the absolute bottom; buying the junk they sell at your local Shoprite...I know...junk. Started really digging deep and over months of comparing brands, prices, nutrition labels, even tastes/flavors: Allmax Isoflex is BY FAR the most impressive protein I have ever come across. Low calorie/fat 0g/sugar 0g, almost 30g of amino acids per serving (most amino acid products are about 6g per serving). 90% protein PER SCOOP. I take it right after i work out with water and its good, but mix with your choice of milk and its outstanding! And to all the people low-rating this product because of the Prop 65 label by the barcode; do your research, stop overreacting.

This is one on my go to proteins. You get what you pay for and this stuff is worth every penny so far the only downfall I have with it is that the Cookies & Cream is pretty bad if you use water just FYI to everyone.

Isoflex has been my "go to" protein when it comes to meeting my macros. This has helped my cut tremendously. I was at 231 pounds the worst shape of my life, and I started with Optimum Nutrition, but I wanted to see what they hype was all about with Isoflex and havent turned back. I used to put PB2 in my shakes, and this Peanut Butter Chocolate has helped me eliminate PB2 all together and save un neccessary calories. Is it expensive? Yea. But it depends on how much you really care about the nutrients going in your body and what your willing to spend. Thank you Isoflex.

Bought this product at my local store. I am buying 5lbs of iso a month so I am consuming a lot of isolate on a basis. Ingredient and quality are there, no doubt about it and it's good to get a product with 90% of protein. My only negative point is that it says it taste like vanilla but that is completely wrong; taste mostly like coconut and god knows I hate coconut taste. I will drink it all but probably won't buy another one because of this coconut taste (which is not vanilla at all).

Been using IsoFlex for the past few years. I love this protein and it is the best whey isolate protein on the market. Taste is fantastic and can easily blend into water or milk depending on your shake preference. Will continue to purchase again and again.
