ISOFLEX: TRULY SUPERIOR PROTEIN

All new and improved ISOFLEX is the ultimate in taste and the ultimate in quality. Not only does ISOFLEX have a brand new look and great taste, using cutting edge technology, it's a pure 100% Whey Protein Isolate. ISOFLEX is significantly lower in lactose, fat, sugar and carbs, compared to regular WPIs too! If you're looking for the highest quality, most premium and fastest absorbing protein, then look no further than ISOFLEX; a Truly Superior Whey Protein Isolate.

HRI Banner

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 t retain an exceptionally high protein yield while maintaining enhanced bioactive whey fractions.

IsoFlex Properties

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. 27g of Pure Protein that has been laboratory tested, certified and approved.

Truly Superior Banner

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.

ISOFLEX now features SCOOP-LOCK technology. Together we can put an end to the scourge of Scoop Loss.

Gone are the days of digging through your protein to get your scoop. SCOOP-LOCK is ergonomically designed to lock your scoop into place the first time and every time! And it's right there at the top of your ISOFLEX when you open it! Scoop-Lock is available on all ISOFLEX, ALLWHEY Gold, ALLWHEY Classic, and HEXAPRO products and it's only from ALLMAX. Look for the rugged new Ergo-Lid on ALLMAX products with Scoop-Lock inside!

THE TASTE YOU CRAVE - THE RESULTS YOU DEMAND

Don't give up taste to get the power of Whey Protein Isolate. The first thing that really sets ISOFLEX apart from any other protein powder on the market is its taste. It tastes amazing! And with eight delicious flavors to choose from, there's sure to be one that satisfies your distinct taste buds.

Love these flavors! I’m waiting for you to get the cinnamon cereal so I can catch it on sale! Solid flavors and the birthday cake goes great with some pumpkin pie spice or powdered peanut butter. I mix in water after my workout and missed with no issues. *

The cookies and cream is definitely a winner. Not too sweet and plenty of protein. If you're looking for a new flavor to try, this is it. I will be back to reorder.*

Great protein. Decided to try this after getting the "gold" version and wasn't disappointed. The product is good, the taste is just ok though, which I figured because it's a purer protein. The gold version tastes amazing, isoflex has little flavor. So if that matters to you, look elsewhere. Plus it's pricey. Those are the negatives..*
