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.

ISOFLEX: TRULY SUPERIOR PROTEIN

Because of the high quality and purity of ISOFLEX, you get some of the fastest protein absorption out there. 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.

Can I use Isoflex with other supplements?

Yes, you can. Depending on your goals, Isoflex complements many other AllMax Nutrition products to help you bring 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.

How do I take Isoflex?

Combine one 30g scoop 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 about 1 cup (300 ml of water) providing 54 grams of pure protein.

Isoflex mixes well in a shaker cup but can be combined with other ingredients in a blender as a smoothie too.

Whey Protein Isolate Vs. Concentrate: 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 eight 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 that contain only 30-80% of protein and include higher levels carbs, lactose (milk sugar) and fats. Additionally, the macronutrient profile of Isoflex is exceptional and provides you with a whopping 27 grams of pure protein!

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 which will reduce hunger cravings, stabilize blood insulin levels, and put your body into 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.

When should I take Isoflex?

Post-Workout:

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). We also recommend stacking with a quality carbohydrate drink like CARBION. This will boost protein synthesis and prevent muscle breakdown. A second option popular with bodybuilders is C:VOL 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.

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. We understand mixability is crucial, many times we are mixing up shakes on the go or at the gym in not so ideal circumstances. 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 scoop your protein into your shaker cup first and then add water without it clumping and sticking to the bottom! This makes it great for storing a serving in your gym bag for post-workout nutrition.

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.

Whey Protein Isolate Benefits:

Isoflex contains a very special hybrid of Whey Protein Isolates that we call HRI. HRI in Isoflex yields a very high percentage of protein. It provides exceptional levels of bioactive whey protein fractions due in part to gentle processing at cold temperatures that ensure the protein is intact and non-denatured.

You can see this from the chart on the label that shows our typical levels of bioactive fractions such as Beta-Lactoglobulin, Alpha-Lactalbumin, Immunoglobulin, Lactoferrin, BSA and so on. Each of these fractions are partly responsible for many of the health giving properties attributed to whey protein.

 

Is whey better than soy?

There is quite a lot of controversy among nutritional experts about this. Although whey protein isolate 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. The benefits of whey protein isolate Isoflex, is that it 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.

Can I use Isoflex if I’m lactose-intolerant?

Isoflex is lactose-free and is well-tolerated by those who have a lactose intolerance.

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.

  1. The F.

    I got this site from my friend who told me on the topic of this web page and at the moment this time I am browsing this web page and reading very informative content at this time.

  2. Aaron G.

    Honestly probably the best Protein I’ve used. Mixability is great, taste is just as good. Definitely the flavors for me are Chocolate Peanut Butter, Birthday Cake and the Cookies & Cream. I use them in just a straight Shake, or I’ll mix in my Oats/Cream of Rice!

  3. Stephen

    Isoflex has been my #1 protein for years however they changed the formula or something for the Cookies & Cream flavour and it is TERRIBLE. I thought it went bad so I returned it and picked up another (from another store) and it was the same crap. It doesn’t mix with water even after shaking for 10min, it has a chunky texture and it tastes like crap. It is a completely different texture, colour, and flavour than before and it sucks. I have to find a new protein now and I wish I didn’t have to.

  4. Sam M.

    I’ve been using ISOFLEX for a few years now, it is my favourite protein powder by Allmax for the type of training I do. I’m a mom and a hockey player so I need to stay strong and lean. This product dissolves well and the flavours are all great. Caramel Macchiato is my favourite!

  5. Kaitlyn Z.

    Amazing taste and mixes perfectly every time. No chunks=happy me lol

  6. Latest H.

    I’m often to blogging and i really recognize your content. The article has actually peaks my interest. I’m going to bookmark your site and preserve checking for brand new information.

  7. Tajinder S.

    Im obsessed with this protein powder. I use this for my protein shakes and my dessert recipes. The texture is amazing. It blends so perfectly for baking and doesn’t leave any clumps. The flavour is a bonus!

  8. Amber C.

    This protein powder is an absolute staple and has been a part of my daily routine for years.
    The chocolate peanut butter is by far the best tasting protein powder on the market, with birthday cake being a close second. It also blends and mixes easily with any liquid.

    I use this protein to make shakes, protein bars, pancakes and other protein packed treats.

    100% recommend!

  9. Fashion S.

    Wonderful items from you, man. I have be mindful your stuff prior to and you are simply extremely fantastic. I actually like what you have bought here, really like what you’re saying and the best way during which you assert it. You’re making it enjoyable and you still care for to keep it wise. I cant wait to learn much more from you. That is actually a tremendous website.

  10. Matt P.

    This is the easiest mixing, best tasting,purest isolate on the market. My favorite flavor is chocolate peanut butter !

  11. Kristen L.

    I absolutely love the Isoflex protein. The selling point for me is obviously the purity of the source, but it needs to taste good in order for me to consume in on a daily basis! I am extremely happy with this product. Thank you Allmax for creating such a great product!

  12. Nicole C.

    I’ve been using this Isoflex Whey Protein for 2 years now. I lost 100 lbs over the course of 15 months and this protein powder was a big part of my journey! I drank it everyday after my morning workout and it not only tastes great but would honestly help me to stay fuller longer. The strawberry is my favorite flavor, my boyfriend prefers the birthday cake. Mix it with some unsweetened almond milk and you will think you are drinking a milkshake. It’s that good!

  13. Doug C.

    Quite impressed with Isoflex! Have tried a wide variety of brands over the past 40 years, but since Boss Supplements suggested it 6 or 7 years ago I’ve never used anything else. My wife and I use the banana flavour, not just for our shakes but also in our oatmeal each morning and I put a scoop in my hot chocolate on winter days. Congrats on a superior product – it’s the only protein I’ll use or recommend to those I train!

  14. Hawley D.

    I have tried most of the Isoflex flavors and I specifically use the Vanilla for cooking and baking now. I use it in pancakes, waffles, protein balls, brownies, cakes, or I add it to plain yogurt with berries. The possibilities are endless.

  15. Laura R.

    ISOFLEX CHANGED THE GAME,
    I was looking for a good protein powder and I found allmax thanks to one of my fav bodybuilders, Arya Saffaie, and switching was the best thing I could have done. I had such a hard time finding a protein powder that would have all the characteristics I wanted, my previous protein was making me feel bulky all the time even tho I was eating so clean and once I change to ISOFLEX I noticed the difference instantly. The fact that is super clean not loaded with extra fillers and they still make it taste AMAZING!!! I put protein powder in all my recipes so flavor is definitely super important as well as what I’m putting in my body!

  16. Mary T.

    Chocolate PB Isoflex is by far my favorite protein in the world!! Flavorful, digests well, and made with high quality protein. You can’t beat it.

  17. Alberto M.

    Since i started lifting weights, and throughout my whole bodybuilding career i really Haven’t used any other protein other than Isoflex. My reasons are simple really; it’s tastes great, mixes well, and i have ZERO issues with digestion. This is quality stuff!

  18. Gerardo C.

    Honestly the best protein shake I’ve had ! Great for recovery and taste delicious. I get the chocolate mix !! I highly recommend to all my friends ! Love you .. ps thank you for the free amino energy drink !! It’s also great

  19. kris

    Best protein for me
    I always come back for this protein . Actually I’ve tried so many protein and this is the only one that works for me. Plus I am so picky with protein bec I’m lactose . Doesn’t bloat me . I’ve used this product for years now

  20. robert m.

    Great protein
    Very good!

  21. Wendy G.

    I like this protein, it’s very tasty and mixes well. The caramel macchiato is very good! Good protein for your money!

  22. Helena T.

    This is by far the best protein I that I’ve ever tried. Great tasting, perfect price point, convenient measuring scoop (no digging inside for the measuring scoop like most others). It also leaves me feeling full for hours after I consume it!!!

  23. Kevin D.

    My boys love the taste of it
    Good product

  24. JD M.

    Has been my favorite protein for years. Taste just like a milkshake and doesn’t leave you feeling full & bloated after. Not to mention I noticeably started putting on muscle after I started taking this regularly.

  25. Randy H.

    Isoflex is great. Take this protein for a few days and you will feel the difference. It does not give some crazy energy burst, but a steady added energy throughout the day. The amino acid profile is much more than the base protein you find at grocery stores.

  26. Karen I.

    This is my go-to protein powder. I’ve been weight lifting for fifteen years and tried and researched many whey protein powders. This is by far the most stacked: 90% protein, 6 grams of BCAAs, easy to blend, amazing taste

  27. Emiliano C.

    The best protein in the business. I, as a pro fighter, need to be in excellent condition to keep the rithm of my trainings and fights and definitely this is one of most complete supplements on my diet and preparation.

  28. AARON F.

    THIS IS MY ALL TIME FAVORITE PROTEIN BLEND AND FLAVOR! I ALWAYS HAVE IT FIRST THING IN THE MORNING FOLLOWING MY CARDIO REGIMEN. 2 scoops blended with a cup of water and almond milk, banana, spinach, and oats and breakfast is served quick and simple give it a try i promise.

  29. Lisa M.

    Husband’s Go to Protein
    My husband enjoys this protein and it was worth the value.

  30. Dennis T.

    Great stuff! It mixes pretty well and tastes great. Most of all, I don’t feel bloated or have burps after consuming. I will definitely buy this again!

  31. Katie S.

    Love the taste of Chocolate Peanut Butter! Mixes great even with water.

  32. Angela D.

    Great product
    Always arrives quick. Great flavor and price!

  33. Jessica K.

    This protein has been my favorite for years now, it’s one of the only proteins that I trust. I normally have digestion issues and certain brands in the past have been difficult for me to digest. This protein has never given me any issues or bloat! Not to mention the chocolate peanut butter flavor is AMAZING!

  34. Ashley W.

    I absolutely LOVE the Isoflex Chocolate Peanut Butter Protein Powder! It tastes like a liquid Reese’s Peanut Butter Cup and mixes really well. It is a super easy and tasty way for me to get in another 27g of protein daily!

  35. Scott S.

    Isoflex is a delicious and high quality protein powder. You can’t beat it. You can’t beat the low calories and high protein content either.

  36. Caleb B.

    I love this protein. i have a hard time digesting inferior proteins and this is the only protein im able to actually consume and not have gastric distress. not to mention the flavor is awesome and it goes down smooth with zero clumping issues. i love to put this in my oats first thing in the mornign and it also naturally sweetens my oats.

  37. Steve K.

    quality, flavor, mixabilty all 5 stars… Chocolate peanut butter is my go to but never have been disappointed by the other flavors. I use this post workout With Carbion and it makes the ideal post workout drink.

  38. John M.

    I am lactose intolerant but prefer whey protein rather than alternatives. This protein is the only one I’ve tried that does not affect my stomach in any way whatsoever, and for me, that alone is worth 5 stars. Post-workout I just have it with water, and the taste is good. It’s awesome. I’ve been sticking with Allmax for obvious reasons and will continue to. It’s a solid protein, no bloat, tastes good, and works. Can’t really ask for anything else.

  39. Destiny H.

    I have tried many isoflex products and well when my weightloss journey started 6 years ago Allmax had me hooked on theirs! I Love this flavour the best! Still have several to try but this keeps me coming back for more. Not only is it good in a shake but its also good in hot chocolate bombs, protein balls and muffins! As an athlete and coach I always start my recommendations to this flavour and brand!

  40. Loreen

    Been working out for over 15 years and I’ve only changed protein powders 3 times because i’m sooooo picky on what I put into my body. Welp, 3rd times a charm because I’m sooooo happy with Allmax’s Isoflex because of how clean it is, and that it’s not loaded with fillers. I love that it’s lactose-free, so it’s easier to digest, and the carb/sugar/fat content is so low. And the FLAVOR!!! Super yummmmyyyy! I only need to use (literally) about 2-3 ounces of water to make the delicious drink with no clumps, and I don’t feel bloated. Thank you Allmax for an amazing product! 🙂

  41. Matt

    Best tasting and highest quality protein on the market! I’ve been using Isoflex for years and it’s a staple product I use every day. I’ve tried them all and nothing compares to the quality, taste, ease of mixing, and results!

  42. Matt P.

    I’ve been using a Isoflex for over five years. Where do I start. It’s the highest quality best tasting protein on the market. My favorite flavor is chocolate peanut butter. All the other flavors are amazing to

  43. Kass

    Favorite protein by far! So many great flavours

  44. Daniel M.

    Isoflex is my post workout go to. Easy to mix, no bloat or GI discomfort and amazing taste! I’m partial to the chocolate peanut butter

  45. Brett K.

    Best tasting protein on the market and you know you are getting a clean, quality product that has exactly what’s on the label. All supplement companies should be held to this standard. Gold standard company IMO. I’ve been an IFBB pro for 6 years and moved from Dymatize to Allmax 4 year ago and never looked back.

  46. Jacques S.

    Love this product

  47. Billie

    LOVE IT!!! Allmax Isoflex protein is my absolute go too. I frankly love the light consistency. Not heavy like other protein powders. Cookies and cream is definitely my favorite! I also love that you can partner this protein with oatmeal/coffee or anything really. Also great for smoothies! 🙂

  48. Jasmine

    The smoothest, most delicious protein I’ve had! I also love the quality in all of allmax products, especially the protein. I can go into prep knowing the macros in the protein won’t hurt my prep. The best!!

  49. Lanalee P.

    Allmax was the first supplement brand I have ever used!!! Over 8 years ago and has been my number one since! ISOFLEX is one of my favourite products made by ALLMAX !! The protein is the highest quality, Super easy to digest (and I am someone who finds it hard to digest a lot of things), mixes super well, I don’t ever use those shake balls!! AND they have so many flavours to choose from! My favourite to drink is chocolate mint & my favourite to mix with my food and smoothies is banana! Love it and would never turn back! (Also I love how they are third party tested, so no junk!)

  50. Ariana G.

    I LOVE isoflex. It mixes so well. I love how you can add more water to stretch out the volume and it still keeps such great flavor. Chocolate peanut butter is Devine. Not to mention the macros are great.

  51. Brandon M.

    Seriously the best. Great quality, so many flavours. Best supplement company on the market and this product is a staple!!

  52. Sarah P.

    I am a big fan of Allmax ISOFLEX and have been using this product for years to help support my nutrition and fitness journey. It’s a very high quality product and uses 100% pure whey protein. Not only does ISOFLEX have a great taste. It’s low in lactose, fat, sugar and carbs. I recommend this product to anyone who is looking for a great protein supplement.

  53. Bryan S.

    Hands down my favorite protein! Mixes very smooth (no clumping) and all the flavors are absolutely delicious! My go to is chocolate peanut butter!

    I love the taste and it’s perfect for post workout or a shake in between meals! I highly recommend 5/5

  55. Ashley

    I truly love this protein! It’s smooth, tastes great and doesn’t get chunky when you mix it in your shaker bottle.

  56. Steven

    I have used Isoflex for well over 10 years now. Being type 1 diabetic, I love that this is no sugar and super low carb. It helps me hit my fitness goals while keeping my diabetes happy!

    Mixes and tastes better than anything I have tried! Keep it up Allmax! PB Choc for the win!

  57. Kiana

    Best protein ever!! Been using it for years now & I love it. All of the flavours are so delicious but chocolate is definitely my favourite 🙂

  58. Tyler B.

    I don’t go a single day without isoflex! I rotate between multiple different amazing flavors and never get tired of them! And the assurance that I’m getting a high quality product and maximum recovery from my training is my top priority when choosing my supplements!

  59. Josh W.

    I’ve used Isoflex for over 10 years! It’s my favorite tasting protein and gram for gram it’s the highest protein per scoop on the market! Choc PB is always my go to but all the flavors are amazing!

  60. Bri

    Amazing taste and so great for when you’re busy and on the go!! Game changer!!

  61. Rachel

    So tasty! Really fills me up. Makes a smoothie thick.

  62. Michelle M.

    My favorite protein of all time! I have a huge sweet tooth and all of the flavor varieties help kick my cravings and hit my goals, especially during prep currently. Also great for cooking

  63. Lars B.

    Been using all max supplements for some time now. For carb powders, digestive enzymes, pre work outs, protein powder, sleep aids, liver care. These I are just some of the quality products I use on a daily basis as a athlete and competitive bodybuilder. High quality products used by the best.

  64. Michelle

    My favorite protein of all time! I have a huge sweet tooth and all the flavors curb my cravings and help my hit my goals especially during prep right now. Also great for cooking!

  65. Allison T.

    Taking nutritional profile, taste, and quality ingredients into consideration, this is by far the best whey protein on the market! I’ve tried numerous brands of whey isolate before trying ALLMAX and none of them compare. IsoFlex is low in sugar, carbs, and fat and versatile for any health and fitness goals. I’ve known many people including myself who have used it while prepping for fitness competitions. Plus, the fact that any of the flavors taste great when mixed with water is pretty phenomenal.

  66. Angela R.

    The best protein I’ve ever had! Every flavor I’ve tried, actually tastes good, no clumps either. Very low in carbs and fat, and doesn’t cause any bloating or digestive issues.

  67. Jessica

    After tasting Isoflex I will never buy another protein powder. Tastes great and mixes easily with water. Great product!

  68. Frank G.

    I have been using iso flex for over a year now it’s great tasting and easily digestible. I have tasted and tried all different brands and they usually upset my stomach. This 2 scoops and I’m good , pop it in the freezer and is like ice cream on prep. Best isolate on the market A1

  69. Alyssa I.

    I’ve been using ALLMAX Nutrition for the last 10 years supplementing it with my training (wrestling, MMA fitness, kettlebell training and high energy circuit training). It never disappoints with the flavour, mix and taste with the protein powder. I love many of ALLMAX supplements and grateful to be an ambassador athlete and promote to all clients/friends I train/coach!

    Great product and quality taste! Canada’s guidelines are held to a higher standard than US brands so basically what you see on the label is what you get!

  75. Alessandra

    Allmax has the BEST flavours! I am an avid supplement user & have tried a lot of supplements over the years. I can whole-heartedly say nothing compares to the taste, consistency and nutritional value of Allmax. Would highly recommend their products to anyone!!

  81. Daryl G.

    Incredible taste and ease of mixing. Excellent consistency, great quality & value and the macros are fantastic. Hands down game changer for a solid protein source. Thanks Allmax!

  82. Matthew R.

    IsoFlex is for me perhaps the best tasting supplement in it’s category bar none. It’s not “tolerable” like most protein shakes, it’s actually yummy! In my estimation you will not be disappointed. Well done guys!

  83. Mindful

    Great source for protein
    Chocolate is one of my favorite flavors

  84. Camille

    Love it great protein, great quality, delicious and the price is very reasonable.

  85. Steve

    Excellent protein
    This is one of the best proteins you can buy. I’ve been using it for the last 3 years and have loved it. The taste is good, it blends super easy, and its a good add on to smoothies. The fact that it’s also tested in a third party lab for contaminants/toxins makes it even more appealing.

  86. Mike t.

    Great product
    Taste great, low fat, high protein. What else do you want?

  87. Steven

    Favourite protein powder
    This is my default protein powder. It tastes much better than most of the others I have tried, kind of like cold hot chocolate.

  88. Will

    I was looking for a protein with low cholesterol, low carbs and low sugar that was easy to drink. For me this protein fits that bill. Great flavors are Chocolate, Chocolate Peanut Butter and Caramel Macchiato, they are my mainstays. Banana was ok. Pineapple Coconut lower then average tastes. I had to pour out Chocolate Mint as the Mint flavor was artificial and way overpowering. I have just received Cookies and Cream and it smells awesome but i have not tried it yet. I am sure it will be delicious. While drinking this 2 times a day as Meal Replacements for my breakfast and dinner and eating a normal meal at lunch i have lost 22.4 lbs and gain muscles i havent seen since highschool. Needless to say i am a FAN!

    The best we’ve tried
    The product tastes good and blends well with either water or milk. The flavor is a true chocolate without any chemical aftertaste. We don’t experience any gritty, granular texture after mixing with a liquid.

  101. David A.

    Pharmaceutical grade protein
    Allmax Isoflex is the highest quality whey protein on the market in my opinion. Pharmaceutical

  102. HairyCornflake

    Great Tasting Isolate!
    We’ve found this to be one of the better tasting isolates that we’ve tried. It goes great with all sorts of different mixers. If you’re looking for a descent isolate, give this a try.

  103. M.P.

    Best protein I’ve found after 3 years of trying different brands.
    The only protein I will buy. Low cholesterol, low sugar, high protein. Blends into water in a shaker cup effortlessly and tastes great. Definitely worth the cost compared to some other products out there.

  129. Matt E.

    It’s a delicious & super nutritious energy start to our day
    My boyfriend and I have the same breakfast every day (when at home). It is, Bob’s extra thick, gluten free oatmeal and the recommended portion of the Isoflex chocolate protein powder, mixed into the cooked oatmeal, I add a pinch of cinnamon & 1/4-1/2 teason of organic freshly ground peanut butter & 1/2 cup blueberries. I add unsweetened almond milk, or 2% cow’s milk to taste. It’s a delicious & super nutritious energy start to our day!

    Longtime user of ON Gold Standard, which is still the best bang for the buck protein in my opinion. This is really high quality stuff and worth the price premium.

  142. Andre P.

    I order this Powder for my mothers diet and to date, is the only product I’ve bought 5+ times. Without fail, this is the most delicious and quality shake she’s had. It has a good balance of nutriment and flavor. Would recommend to anyone looking for a nutri-filler to their diet!

  143. Abel

    I love the product
    Well despite the late delivery, I love the product. I’ve been using Isoflex for about a year now, yielded excellent results since then. This brand is probably the most easiest of whey products to mix, as far as the regular flavors go, never had any problems with any chunky spots or anything. I like it even better than the Isopure products. It’s a great investment, go for either chocolate or vanilla.

  144. Gaddi

  145. Rachel

    This flavor tastes great and is a good value for the price.

  146. Tom

    mixes well and tastes good. A little expensive but may be worth it since it is an isolate

  147. Corporate P.

    Best available protein powder for it’s price.
    I’ve tried many proteins and believe All Max Isoflex Isolate competes with very expensive brands. The product taste like a chocolate malt and dissolves quickly and completely in milk, water etc. It is not thick, like most protein powders and taste much better. The protein does not produce internal gas at all. When working out, muscle growth results speak for themselves. My new favorite.

  148. Kenny O.

    Great
    This stuff tastes amazing, the chocolate chips aren’t necessary and didn’t even know it had any until the first shake lol also, great if you’re lactose intolerant or don’t digest milk products well.

  149. Jerrod N.

    Image is for old formula but received new product.
    I do love all the Isoflex products and actually got the new one with the new formula. Based on the image I thought I was getting what was pictured but did not receive this one. I am fine with my purchase but wish I would have known because I can get the new formula locally, but all is good. I would suggest updating the images so that there is no confusion.

    Great product, but lose the chocolate chips
    Don’t care for the added chocolate chips, seem unnecessary. But I keep coming back to this protein every time I switch to something different. Tastes good, mixes well and has a good ingredients list with no filler.

    All Max Isoflex
    I think this is a great whey protein isolate. I’d been using ON’s Platinum Hydrowhey, which was also great. But I’m finding better results with this product. I would recommend this to anyone looking to make size gains in their workouts.
