What Sets ISOFLEX Apart?

What sets ISOFLEX apart

What is whey and why is it so valued as the core foundation of every serious performance nutrition program? Whey is a thin, watery portion of milk chockfull of high-grade protein that’s separated during cheese production. It is extracted through a two-step process. The type of extraction conducted to separate whey from milk is what really determines the quality of whey protein. It’s this exact process that also sets ISOFLEX protein powder apart from others on the market.

How is ISOFLEX made?

ISOFLEX is extracted through CTP™ (Cold Temperature Process) microfiltration. This is a cross-flow microfiltration (CFM) process that removes the larger, less absorbable protein molecules while filtering out fat, lactose and ash that are normally present in whey concentrates and other lower quality protein powders. This is similar to the way reverse osmosis in water purification works.

The Low Temperature Microfiltration Provides Undenatured Protein with many Bioactive Whey Protein Fractions

CFM is one of the best methods for extracting protein on the market today. The whole process takes place at a chilly 4 degrees Celsius, or 39 degrees Fahrenheit and leaves almost 100% of the protein and peptides intact. It also yields the highest amount of undenatured (bio-active) protein available.

Our whey protein isolates are manufactured by chilling or low temperature microfiltration process and dried by indirect heat. The low temperature microfiltration process allows the whey protein isolates to provide undenatured protein with a full balance of bioactive whey protein fractions, including high levels of naturally occurring immunoglobulin, lactoferrin and glycomacropeptides (GMP).

The filtration ceramic membranes used for the CFM process are extraordinarily fine and have the ability to remove even more lactose, ash and fat than the process of ultra-filtration, which is used for lower quality whey protein products. Using this sophisticated process, ALLMAX is able to produce ISOFLEX, a superior ultra pure protein that maintains an optimal macronutrutient ratio, yielding 27 grams of protein, 1 gram of carbohydrate and 0 grams of fat.

ISOFLEX contains pure whey protein

Other whey processing technologies use higher temperatures that cause irreversible unfolding of the protein fractions that can drastically reduce the biological activity of the protein. Based on solubility at a pH of 4.6, ISOFLEX has a mere 3% denatured proteins, which is approximately 10% less than ion-exchange whey protein isolates and typically less than other microfiltration whey protein isolates. ISOFLEX also contains up to 12 times more native GMP than ion-exchange whey protein isolates.

How is whey protein isolate produced?

To produce whey isolate the protein goes through the following steps:

  1. Fresh milk is tested by quality assurance experts.
  2. The curd portion of the milk fat is separated out for cheese.
  3. The watery liquid portion that is chockfull of high-grade protein is filtered through a microfiltration process to remove lactose and ash.
  4. The concentrated liquid goes through the CFM process, which eliminates the need for harsh chemicals used in other processes.
  5. The water is removed and the whey is dried.
  6. Ultra pure whey protein isolate is packaged and ready for our ALLMAX customer.

cgmpAll of these steps are performed at a cGMP licensed manufacturing facility to ensure quality and integrity.


Every ingredient and every lot produced is independently lab tested for purity and quality to ensure consistent quality every time.

ISOFLEX is manufactured in the US with US Dairy Cows. ALLMAX protein products contain absolutely zero protein sourced from China.

Every lot of ALLMAX proteins are tested for heavy metals. No lot is ever released if it does not pass these tests.

21% Glycomacropeptide – contains high amounts of BCAAs and can help stimulate the body to release cholecystokinin (CCK) after eating to signify satiety (the feeling of being full) and help with weight loss.

15% Alpha-Lactalbumin – high in tryptophan, a natural relaxant which can help to reduce stress, improve the mood and increase serotonin levels.

2.5% Immunoglobulin – responsible for producing antibodies to fight against pathogens. They bind to toxins to prevent infections and also enhance the immune system.

1.4% BSA (Bovine Serum Albumin) – provides essential amino acids.

0.1% Lactoferrin – is an iron-binding protein which helps with iron transport throughout the body. It is also a powerful antiviral, antibacterial and antifungal glycoprotein.


1. Can I use ISOFLEX with other supplements?

Yes, you can. Depending on your goals, ISOFLEX complements many other ALLMAX Nutrition products to help you get your training to the next level. ISOFLEX is highly versatile and is considered an ideal base, meaning it can be used well with just about every other supplement. If you’re trying to lose weight or lean out try combining RapidCuts Shredded with ISOFLEX. If you’re trying to bulk up or put on weight Aminocore and Glutamine are excellent products to try in addition to ISOFLEX protein powder.

2. How do I take ISOFLEX?

Combine 1 scoop (30 grams) of ISOFLEX protein powder with 1/2 cup, or 120 ml of water, juice or milk (most choose water or skim milk), depending on your preference, at any time during the day that you need a protein boost.

Most athletes with elevated protein requirements double each serving with 2 scoops of ISOFLEX with 1 cup, or 240 ml water, providing 60 grams of protein. Most bodybuilders are aware that high levels of protein consumption are critical to their success. Most will aim for 1.5 to 2 grams of protein per pound of bodyweight daily and space their consumption throughout the day. ISOFLEX mixes well in a shaker cup but can be combined with other ingredients in a blender as a smoothie as well.

3. What makes ISOFLEX superior to other protein powders on the market?

The first thing that really sets ISOFLEX apart from any other protein powder on the market is its taste. It actually tastes amazing! And with six delicious flavors to choose from, there’s sure to be one that satisfies your distinct taste buds.

Secondly and most importantly, it has been formulated with only the most superior blend of whey protein available – whey protein isolate – many other protein powders on the market use whey concentrates and other inferior blends thatcontain only 30-80% of protein and include lactose and fats.

Additionally, the macronutrient profile of ISOFLEX is exceptional. It’s virtually fat free, lactose-free, contains only 1 gram of sugar and best of all, provides you with a whopping 27 grams of the highest quality protein available!

5. Will ISOFLEX give me big, bulky muscles?

For those of you trying to lose weight or tone up, drinking protein supplements such as ISOFLEX are not going to give you big, bulky muscles. In fact, ISOFLEX can actually help you reach your weight loss goals as protein has been shown to stabilize blood glucose levels. This will reduce hunger cravings, stabilize blood insulin levels, putting your body in an ideal fat burning zone.

For all you bodybuilders out there, you probably already know it takes a lot of hard work at the gym, proper nutrition (including a lot of calories) and genetics to get big and bulky muscles. But ISOFLEX can provide you with the nutrients your body needs to recover from your workouts and is a great protein option to help fuel your muscles.

6. When should I take ISOFLEX?


As soon as you’ve dropped your final set your next step should be to consume an ISOFLEX protein shake with some fast-acting carbs (2-3 rice cakes are a quick and easy option). This will boost protein synthesis and prevent muscle breakdown. A second option popular with bodybuilders is KRUSH LOADED immediately after working out, then 30 minutes later, ISOFLEX protein powder.

For high performance nutrition make every protein option count by consuming high quality protein choices. ISOFLEX is a delicious perfect blend of protein that’ll provide the nutrients you need to take it to the next level!

As a Meal Replacement

To shift your body into an anabolic state (which is essential to increase lean muscle mass) consume a protein shake with 1-2 scoops of ISOFLEX or add a couple scoops of ISOFLEX to a hearty bowl of oatmeal for breakfast.

Pinched for time? ISOFLEX is a delicious, and quick, replacement for a mid-morning or mid-afternoon snack.

7. Do I have to use a blender to mix up my ISOFLEX protein powder?

Using a blender will increase the creaminess of your shake, but ISOFLEX was developed as an instantized protein powder through an advanced technological process, so that it mixes easily in a shaker cup and doesn’t require a blender.  Those who have tried ISOFLEX have commented that it mixes well with water or milk in a shaker cup, creating a nice, smooth drink. ISOFLEX mixes so easily, you can even mix it with a fork.

8. What is whey protein isolate?

Whey protein is simply one of the by-products in the manufacturing of cheese. Whey protein is considered the pinnacle of all sources of protein, as it is readily absorbed by the body and has a very high biological value. Whey protein isolate is a purer form of whey protein as it contains less fat and lactose. It also has a higher biological value than whey protein concentrates. Whey protein isolate is a far superior source than a whey protein concentrate and allows the highest percentage of protein per gram. Although whey protein isolates generally cost more than concentrate blends, the quality is certainly worth it.

9. Is whey better than soy?

There is quite a lot of controversy among nutritional experts about this. Although whey protein has a higher biological value than soy protein, a lot of scientific research has proven that soy protein can also offer a variety of health benefits. ISOFLEX protein powder is composed of exclusively whey protein and has a much higher bioavailable value, but there’s no reason why you can’t include soy protein in your balanced diet as well. However, many people shy away from soy due to concerns over estrogenic proteins.

10. Can I use ISOFLEX if I’m lactose-intolerant?

ISOFLEX is over 99% lactose-free and is well-tolerated by those who have lactose intolerance.

11. I eat beef, chicken and eggs, do I still need to use ISOFLEX?

Unlike animal sources of protein, ISOFLEX travels well in a gym bag or suitcase for a quick protein boost whenever you need one. ISOFLEX is simply a convenient high protein, low fat, addition to your diet plan. For those of you who are bodybuilding and are trying to consume between 1.5 and 3 grams of protein per pound of body weight, you know all too well how difficult and expensive this kind of diet can be. Aside from providing a simple way to quickly and easily get your protein, ISOFLEX also absorbs rapidly and contains 4 proprietary complexes to augment absorption, improve recovery, and increase nutrient delivery.


Terry Lonsberry’s Amazing Transformation

TerryAt the age of 34 and weighing in at 510 pounds, Terry Lonsberry’s life changed for the better when his doctor told him he would not live to see his 40th birthday. With a family history of heart disease, the 6′ 4″, 510 lb Terry suffered from type 2 diabetes, high blood pressure, asthma and coronary artery disease. Now 10 years later, Terry has lost more than 310 pounds and sports an athletic physique that any man would envy.

How did he do it?

The sad part of this story is that Terry was turned away again and again by gyms and trainers alike and the only solution the doctors could offer him was gastric bypass surgery.

People looked at me like I was a disease.

To them, Terry was nothing more than a lawsuit waiting to happen. Their treatment added to Terry’s humiliation and isolation, he felt trapped and it was almost enough to set him back.


Terry was determined to get control of his life and he persevered. He designed his own fitness program and enlisted the help of a few choice ALLMAX products, namely ISOFLEX Whey Protein Isolate. With a little dedication and a whole lot of discipline, Terry lost 152 pounds through sheer determination.

Terry Before and After

He was halfway there.

In 2007, thankfully, Terry found a trainer who was willing to work with him to achieve his goals. After two months of meeting trainer Joey Palladini from Able Body Consulting Studios in Nanaimo, BC, Terry dropped an additional 30 pounds, his blood pressure returned to normal and his diabetes was now under control.

I don’t know why I waited until I was 40 to do this, I was dying and he saved my life.

When Terry started working with Palladini, he was barely able to complete one single squat, had trouble getting up and could barely make it up one flight of stairs without gasping for breath. Palladini devised a seven-stage workout plan spread out over a year that focused on burning fat without sacrificing muscle.

The weight had to be shredded off slowly in order for the body to transform in a healthy way.

Terry was committed to this program. He had complete trust in his trainer, followed his fitness and diet routine to the T and never missed a workout. After one year, he lost an additional 110 pounds, 43 inches and traded in his 5X T-shirt for a large. His percentage of body fat moved from 43.3% to 22.7%. He can now perform squats with a 250-lb barbell.

Getting into shape and working with a phenomenal trainer has inspired Terry to follow the same path and become a personal trainer.

I want to save one life, like Joey saved mine. Anyone can turn their life around they just have to put their mind in the right place. I really want this story to motivate people.

Terry has caught the bug and is now training for his first-ever bodybuilding competition. Everyone here at ALLMAX Nutrition is very proud of Terry Lonsberry’s amazing transformation and hopes to see him onstage.

Josh the “Hard-gainer”

Before: Height: 5’10”, Weight: 129 lb, Arms: 11.7″, Bench: 95 lb, Barbell Curl: 45 lb

8 Months After: Height: 5’10”, Weight: 167 lb, Arms: 14.3″, Bench: 180 lb, Barbell Curl: 95 lb


Josh gained 35 lb in 8 months using ISOFLEX and QUICKMASS and his this to say on his transformation:

“I never thought 8 ½ months ago I would be almost 40 pounds heavier and more than twice as strong. Before that I was a scrawny 129-pound kid. I had already joined a gym, but didn’t know how to grow. I discovered the importance of having enough calories and protein in my diet to gain weight and strength. I started on a simple 3-day split routine, and my friend gave me some sample packs of ALLMAX ISOFLEX for post-workout shakes. I found that when I started taking ISOFLEX shakes that I would work harder in the gym so I wouldn’t waste the 50+ grams of protein. I began eating more and not using my ectomorph body type as an excuse to be skinny. See before I started making gains I thought that being skinny all my life and always having a high metabolism would ensure that I wouldn’t be able to grow.

“This is a message to all you kids that think you are a hard gainer – if you have a solid nutrition plan and workout schedule you commit to, you will gain muscle. But to the nutrition side, you must consume an excess amount of calories to gain any kind of weight. The reason your weight doesn’t go up is because you don’t consume enough of the right kind of calories. I fixed this problem by drinking a delicious Cookies and Cream serving of QUICKMASS every day, providing my body with 1010 extra calories per serving. The reason I chose ALLMAX supplement line is because they are great tasting products, and they have a big selection of flavors and products, ranging from protein powders to creatine and pre-workout formulas and more.

I have transformed my body while gaining strength and self respect in the process.

I know that the taste of some people’s current protein powder leaves them not wanting to use whey, but trust me, Peanut Butter Chocolate ISOFLEX tastes amazing and not just amazing for a protein powder but for a milkshake. This is the main supplement I used to get the necessary protein post-workout protein. I would recommend any new lifter to use safe natural supplements like ALLMAX. With ALLMAX supplements, I become the Teen Transformation of the week on”

Jason lost 50 lb with ISOFLEX

“I am a 33-year-old Special Needs school teacher from Toronto, Ontario. I began using your ISOFLEX with a moderate exercise and diet program over the past 8 months with fabulous results. All my friends and co-workers have suggested that I contact you with my story. They all feel that I would make a great before and after story. My body and mindset have completely transformed from your fantastic product. When I take my shirt off now people are shocked at my muscle mass and definition versus 8 months ago where people were shocked because of my fat and love handles. I have dropped about 50 pounds of fat, gone from 230 pounds to 180 pounds of muscle and confidence. I have gone from a 38 inch waist line to a 31 inch waist line. Your product has transformed my life and I just want to thank you for that.”

Joe from British Columbia writes:

“I live in Nanaimo, BC, Canada and there is a Fuel store here. The owner Dave set me up with some ISOFLEX and I’ll never use anything else again. It mixes with water with ZERO clumping within only a few shakes (yes, I put the water in first!) It tastes amazing, and compared to any other protein powder, I couldn’t believe it. Besides the taste, it works wonders! Absorbs mad fast and you really can feel it. I’ve got a 2 pounder on my desk here at work and everyone stops by to read the label. 30 g scoop, 27 g of protein – Amazing guys! Great product!”

Shantelle writes:

“Just wanted to give kudos to the company that makes ISOFLEX. I am never without this protein powder in my home and I use it at least once per day. I am a powerlifter and searched for a protein powder that tasted great and I found it! What was even better is that it is high quality and dissolves quickly and easily. I actually add it to my coffee pre- and post-workout and it mixes better than any other brand I have tried. It is also the only protein powder that I enjoy in water. I promote this product with my friends in real life and online like no other.”

Frank from Connecticut writes:

“I’m a fifty eight year old man who has been exercising and using protein products for close to forty years. I have to say your IsoFlex is the best so far and something I will be using from now on. I have a two pound container of the strawberry and it is delicious and very easy on the gut. Tonight I really needed a snack before bed but did not want to eat anthing bad, so I put one level scoop of the strawberry IsoFlex in a cup with four oz. of whole milk. I always use a blender but didn’t want to make a lot of noise so I started to mix it with just a spoon. Wow! I couldn’t believe how easily and thoroughly it mixed. The taste was fantastic and it satisfied my hunger. Thanks for everything I’ve been wanting and waiting for in a protein supplement all my life.” ~ Sincerely, Frank B, Norwalk. CT
