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. Most bodybuilders are aware that high levels of protein consumption are critical to their success. Most will 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. ISOFLEX mixes well in a shaker cup but can be combined with other ingredients in a blender as a smoothie too.

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?

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.
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, Immunoglobin, 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 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.

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. Edward M.

    Love Allmax Isoflex
    I love this protein powder, doesn’t clump up and breaks down awesomely. Great taste ( but to be fair, I only use Vanilla)

  2. Victor H.

    Thumps Up
    Have gone through over several proteins. This has been my favorite. Doesn’t get me bloated. This will now be my go to for protein powder.

  3. Naimah

    Only protein powder we use!
    Amazing product. Clean ingredients. Perfect for bulk, cut, and maintenance, and every flavor is bomb (but this one is the best)

  4. zenaida a.

    So I’ve bought a few flavors, chocolate, caramel machiatto, and chocolate peanut butter. They’re all amazing and they keep me full and the powders themselves thicken with whatever liquid. THE VANILLA flavor is the worst I’ve had. It tastes horrible and the consistency is not up to par like the other flavors. If I put it into my cream of rice, it makes my rice all watery!

  5. dale b.

    great product
    fast delivery, tastes good, not great but no sugar. costs $20 more at popeyes. so far seems to build lean muscle.

  6. Phillip R.

    An excellent product for someone who needs protein
    My wife has used this product for years. She mixes it with clear soda and is completely satisfied with flavor and taste. She is on dialysis and ISO FLEX provides her with all the protein to start her day.

  7. Lucianny E.

    Very good
    It is not very sweet, it tastes good and gives a very good protein contribution. 100% RECOMMENDED

  8. Cassi

    Stop looking and buy this!
    Absolutely amazing! I eat it with cream of rice and it tastes like CAKE BATTER!! So good! Hits my sweet tooth without the guilt! I kid you not, we have purchased over 10 tubs so far and that number is only going to go up! Absolutely amazing! Part of my daily routine. Soooo good. Thank he sprinkles add even more joy to it! Yes yes yes!!

  9. Ken K.

    Top protein powder
    Chocolate peanut butter flavor is great, tastes like Reese’s. Macros and ingredient profile is possibly the best on the market. Great scoop and holder design. Perfect for getting protein in on a cut, most other powders will be higher in calories and lower in protein than this one. Mixes well and bakes better than the top competitors you will find in store.

  10. Rudy H.

    Great product!
    This is my go to protein. Great placement of the scooper!! Genius! I mainly use it in my coffee. Just make sure to let your coffee coop a little otherwise it will curdle.

    My family and I have tasted many different brands of protein powder, but we are unanimous in stating that this brand and flavour is the best ever!

  24. Christopher Z.

  30. Vance R.

    Best protein the most
    The best whey protein on the market.

  31. keel

    Honestly the best protien powder
    I remember buying this in the p90x days of fitness, different look but still the same product. No need to blend into an elaborate smoothie, just mix with water, stir and down it. I stick to the mint flavor and myself I also mix in PB2, easy and tastes the best of all the protein powders with no after taste.

  32. Kelly M.

    Bad batch
    This cannot be the real product , it has a distinctly different taste , disgusting .

  33. Mikhail S.

    Wonderful Amazon service!!!
    I use it as protein shake after workout

  34. Ricardo V.

    El mejor
    Vale cada centavo !

  35. D

    Great product – Fun flavor
    Tastes good with milk, banana and a ton of peanut butter.

  36. Dmitriy Z.

    Nice product
    It’s very good product

  37. Itzel

    Good taste
    The taste is very rich, not as cloying as chocolate.

  38. Terry B.

    Great Taste w/ 27 grams of Protein!
    As a healthy person, all I want in my supplemental nutrition is lots of protein and a great taste. I’d rather not hold my nose to drink. You have found the whey product of the Gods.

    Goes great with Almond Milk.

    Drink up!

  39. James

    Tastes good
    I bought the mint chocolate chip and it really tastes like mint chocolate chip.

    The container is easy to open and the scooper is always on the top.

  40. Kali G.

    It’s protein powder
    Low carb protein powder, it blends well in a shaker bottle. The banana was okay. Like a very ripe banana with a hint of chemical to let you know it is artificial. The Orange flavour was created by some dummy who was told that vanilla flavour was called orange and now makes vanilla flavoured things and calls them orange (seriously don’t buy unless you hate orange and like vanilla).

  41. Mike

    I love this protein….! It really taste good
    I love peanut butter!….this taste amazing I always get it…it’s pricey but you get your money’s worth. I worked with a lot of trainers and they all recommend this protein…try it especially if you love peanut butter flavor!

  42. Roberto Y.

    Tasty as always!
    I have not yet found another whey based proteine with 90% concetration at that price. Very happy with the results.

  43. BreadMan

    Best protein

  44. P.

    AMAZON had the *best* delivered price – to an obscure state.
    I get this stuff all the time, it’s a go to because of its ingredients. I’ve been sold on it for years if not a decade. I sent some to Alaska and Amazon had the best internet delivery price!! If you’re new to this brand or new to protein powder, compare the ingredients and this is definitely a winner.
    Good quality & extensive ingredients – A lot of what you need (w/o the sugar, fillers & junk). HIGH PROTEIN % per serving !!

  45. Puppy P.

    Yum yum!
    This is delicious! I usually only use half a scoop, but I love that it adds protein while also making my smoothie sweeter. I will definitely give other flavors a try whenever I finally finish this one.

  46. Meshal A.

    Great taste
    If you are a coffee lover this is for you

  47. Katie G.

    Good overall
    Good flavor. Rather expensive

  48. Andi

    Great clean protein
    Such an amazing protein, zero sugar and 1 g of carbs. Highly recommended.

  49. JUAN M.

    excellent supplement!
    It is the supplement that I consume because I like it very well, I see results in the short term… and the price is very good, greetings!

  50. Juan o.

    Its flavor.
    I haven’t tried it yet but I know it’s very good from years ago experience.

  51. 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

  52. KB

    Quality protein that tastes great.
    Quality protein that mixes well and taste great, even mixes with water.

  53. V

    Great protein, worth the price
    My absolute favorite protein for many years. It is pricey compared to the standard whey but personally I prefer the whey isolate vs whey concentrate. I’ll occasionally go with whey concentrate to save a few dollars and always regret it.

    All the flavors I’ve tried have been great and mix perfectly. I’ll usually drink after a workout with orange juice for the fast carbs and I’ll admit, oj and chocolate mint aren’t the best combination but if you are a gym person you’re probably used to sacrificing some taste for better nutrition. Taste fine with water or milk.

  54. Lauren c.

    New favorite Flavor
    I love the chocolate peanut butter and this flavor is just as good!

  55. WBN

    Excellent Protein Supplement
    Excellent. Dissolves quickly and completely. Tastes great. Recommended!

  56. Andi

    High quality protein
    Best protein ever! Highly recommended!

  57. DEE D.

    Cant go wrong with ALLMAX

  58. Erica

    No Longer Need to Search for Scooper
    Reasonably priced, great tasting product for after workout/during the day meal. Usually go for Cookies & Cream or Strawberry flavor. I love the fact they have a section to secure the scooper. Would recommend!

  59. robert m.

    Great protein
    Very good!

  60. Rachel

    Awesome weapon for your nutritional arsenal!
    Good taste. Super low calorie for the amount of protein. Blends great.

  61. hooper

    It literally tastes soo good
    Most proteins will taste like crap and I’ve been through tubs of different kinds but this cookies and cream smacks no cap get it

  62. Jay

    AMAZING – if done right
    I’ve seen a number of reviews complaining about the flavor…artificial tasting (it has artificial sweeteners! What did you expect?), not minty enough, not chocolatey enough, blah blah blah.

    Here’s what you’re gonna do…if you like chocolate mint, go buy an unsweetened or “light” almond milk, cashew milk or oat milk – whichever works best with your diet/macros. Mix in a shaker or blender (preferably blender with some ice and a quality collagen supplement). This stuff is clean, low carb, and will absolutely blow your mind. I’m not buying anything else. No, seriously. I’m not buying ANYTHING ELSE. Ever. Everything I need, and a great flavor to boot….just don’t use water IMO.

  63. JEAN D.

    I recommend her!
    Good protein!

  64. Roberto Y.

    Best whey proteine!
    This is the best whey proteine we have ever try. Is not cheap but as far as now is one the proteins I have found with more proteine % per serving and if you calculate the cost per serving is really good. Great choise, great flavor.

  65. Tammyn5

    pretty good taste for a protien powder
    All protein powders have that same taste, but I really like the pineapple coconut taste. It is better than most and easy to drink with just mixing it with water. I would recommend to others because it also has no sugar and has a good amount of protein in it. Very pleased.

  66. PAUL O.

    All good

  67. Dawn S.

    Normally dislike Protein Powder, but This is da bomb
    Most protein powders are too sweet, or nasty tasting, gritty, whatever, but this flavor is delish. It mixes so easily. Consistency is perfect. I usually do a little almond milk and water. It’s dessert.

  68. G H.

    Best protein available
    Good flavor great protein content. A little more expensive than others but top quality protein. 1 scoop at at time enough. Compare number of servings compared to cheaper powders before you say it’s too expensive

  100. Brock H.

    Still one of the best tasting proteins on the market.
    I have been using this product for years. It is still one of the best.

  101. OE

    Super smooth formula!
    I love it, it blends super easy, no clumping. The flavor is perfect,if you’re into very sweet and typical heavy on the gut type of protein blends, this is not for you as it doesn’t really pack much flavor, but it does go down super smooth and digests really well. No aftertaste or bloating like feeling as you get with other brands.

  102. Lisa M.

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

  103. chris g.

    It’s real protein

  107. pooja u.

    My fitness trainer suggested me.
    Chocolate peanut butter is the best.

  108. pooja u.

    love it!!
    my gym trainer suggested me this brand. and i especially love this flavor of chocloate peanut butter.

  109. Erika

    Tastes great
    I purchased this for a friend and he loved it

  110. Jace

    One of the best chocolate peanut butter isolate proteins
    When I bought this a few weeks ago, I thought I had purchased the chocolate flavor. I didn’t realize I actually bought the chocolate peanut butter, but wow it was a pleasant surprise! Flavor-wise, it’s rich enough to taste like a treat but not so rich that it’s overbearing.

    When it comes to flavor, it’s really tough to nail it with customers of all types of preferences. But for me, this chocolate peanut butter is the closest thing to a chocolate peanut butter sweet/candy that I have ever come across in a protein. Regarding it’s mixability, just like all the other ALLMAX Isoflex proteins, it mixes really well and goes down smoothly.

  111. A. O.

    Our favorite and go to protein
    My husband and I have been using this protein for years now. It is our favorite. It is delicious on its own (even with just water instead of milk) mixed into oatmeal, smoothies, cold brew, pancake mix etc. I would advise if you blend it, to add it last. I make my smoothies all the way first before adding the powder, then do either a quick shake, or fast blend at the end. If you add it all at once you will have a very frothy/head-y, smoothie/drink.

  112. DENNIS T.

    Very happy and highly recommend
    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!

    Best protein I’ve come by

  125. William M.

    Quality protein that tastes great.
    Great tasting quality protein that’s light and doesn’t bloat the gut. Mixes well and doesn’t clump up in the shaker bottle. Love the chocolate peanut butter flavor.

  126. Jackie

  129. Rhouston

    Great Protein
    This is a great protein that mixes well. This particular flavor is not my favorite, but it is a high quality product.

  130. Mindful

    Great source for protein
    Chocolate is one of my favorite flavors

  131. Jaspreet S.

    Close to perfection 0
    Really nice packing and good flavor, I buy one every month. Totally worth it, love that the scoop is attatched on the top so that you don’t have to look for it in the powder. Well thaught

  132. John M.

    Lactose intolerant and this works for me
    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, but if it’s an off day or I just want a snack I have it with almond milk and the taste is very good. Also, no sugar and low calorie, which is great for me.

    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.

  133. Roderick

    great price with great result
    it has good content of vitamins and mostly it has 0 cholesterol and a small grm of sugar i feel great about this all max better than the most expensive whey protein out there i will keep on buying this all max you wont regret it

  134. Charli L.

    Product is great. Just bad choice of packaging.
    We have ordered this product before…it’s great!! Love the flavor. But this time the seal was broken and there was protein powder everywhere. It may have been because the box was a little to big for the container.

  135. Chris a.

    Awesome Protein
    Great taste and great value. Very high quality ingredients.

  136. Jeannine J.

    Good value
    Milk shakes

  137. Little J.

    Tastes great
    Tastes great but hard to get the lumps out of. Need a blender to mix

  138. Shary M.

    Works great
    I blend all my veggies first and then hand stir in the protein. Keeps it from getting foamy. Great flavor

  139. Anthony F.

    Best Isolate on the market
    It’s no secret in the fitness or lifting world that Allmax products top notch, but Isoflex has been a staple in protein powders. Isoflex is always ranked in the top 5 if not top 3 isolates on the market every year. It’s clean, has quality ingredients, there’s no protein spiking and has some of the highest amount of natural occurring BCAAs, EAAs, NEAAs out of any protein powder out there. All falvors are amazing and they all mic well

  140. Camille

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

  141. Nukehead

    Best tasting chocolate peanut butter cup protein I’ve ever tasted
    It tastes very rich and delicious and I really enjoy drinking it. It’s not 100% like the chocolate peanut butter cup candy you have in mind, but it’s the closest flavor to it that I’ve ever tasted. I’ve had experiences with some pretty bad, chalky protein powders, and this is definitely one of the best I’ve ever had. I like it so much that I’m tempted to use more than one serving scoop of it at a time for my shakes. I’ve never felt like doing that before. I seriously don’t know if the other reviewers saying this protein “tastes horrible” are even reviewing the same product. This stuff is amazing.

  142. Mackolishes

    I really like the flavor tasts like a the milk at the end of a bowl of reesepuff cereal

  143. Hawley D.

    The Best No Carb Shake out there
    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.

  144. Michael D.

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

  145. cool

    Do you know how good this *** is?
    This is my favorite brand as protein powder, this is also my favorite flavor. I am such a strawberry lover.

  146. shebakescakes

    Tastes good to me
    This was my first time trying Allmax and flavor, chocolate peanut butter, and I’m pretty impressed. I wouldn’t say exactly like a Reese’s peanut butter cup, but close for sure.

  147. 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.

  148. RET

    Flavor is great and mix well when baked.

  149. Rosemary

    Lots of grams of protein and great taste
    This is the best protein powder ever. Add a scoop of peanut butter and some ice and almond milk and you will be in heaven.

  150. Rosemary

    Fast delivery, great flavor.
    I love this stuff. use it before and after my workouts and if you add a scoop of peanut butter and put it in a ninja blender it’s even better. Fast delivery also.

  151. Curt B.

    Works great, and doesn’t taste bad!
    I’ve been using this for quite some time now, but just found that Amazon carries it. Saves me a trip to the nutrition shop.

  152. Jerry b.

    Love my isoflex
    Best cleanest protein on the market

  153. Jennifer K.

    Great Taste
    This powder is great for making protein shakes with tropical fruit. Flavor is great and no chalky texture.

  154. Lisa

    Great flavor
    I live this brand of protien powder it mixes well and the flavors are wonderful.

  155. Mariela G.

    Great flavor
    Blends very well with my coffee shake and my avocado and spinach shake.

  156. Paola

    Excellent service thank you very much!!
    Very good product, it arrived on time and in addition to what I ordered I received many gifts from the supplier thank you very much! Very happy Excellent service!!

  157. aaron

    High Quality
    Been using Allmax Isoflex for years, especially the chocolate peanut butter flavor. Have never found a better product for my needs; good taste, mixability, and quality results

  158. justin w.

    Tastes Great!
    This has been my choice of protein for awhile now. The only problem with peanut flavour, is that you can’t really mix any fruit in the shake, but that’s not a big deal.

  159. Aileen F.

    I have taken several flavors, without a doubt this has been the best. It’s not as sweet as others.

  160. Amazon C.

    Long time user
    Great after a good work out 😊

    Taste great for what it is
    Fantastic portien powder
    Pineapple flavor is not as strong as i wanted but its protien powder what did i expect xD

  167. Helena

    Great price and taste!!
    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!!!

  168. jr h.

    Superior protein powder
    I’ve been working out/training for 10 years. I have used and tried many different products, both expensive and cheap. When it comes to whey isolate post workout, this is the best I’ve used so far. Amazing taste (birthday cake) , great mixability, easy on your stomach. I highly recommend this product.

  169. Kimberly

    Taste of the protein powder is amazing!!!!! I do my protein smoothie in the am and it adds just the touch of peanut butter! Definitely helps to get my protein in.

  170. Sir S.

    Taste is great. Very similar to peanut brittle and very sweet, so dilute as you like. I also used it to make some pretty delicious protein waffles

  171. Forouzan

    The best whey protein
    I am so happy with this whey protein
    It taste great

  172. Kale

  177. ImaWilson

    Best I’ve ever tasted
    have tried a few choco flavors out there and this is hands down the best I’ve had

  178. Dania

    Deli flavor and fast service.
    I arrive in less than expected. I wasn’t expecting the extra detail that comes with the protein. I didn’t know whether to choose this flavor because I thought it would be very sweet but the Caramel Machiato flavor is delicious! Highly recommended! 👍🏻👍🏻

  179. Constantine M.

    Worth it
    Tastes very very Good. no real bloating feeling, and easy to shake with minimal water if need.

  180. Debbie

    It was great, from start to finish!
    Great taste! Great price! Great service!

  181. COTUS

    Best Tasting Protein I’ve Ever Had!
    This is easily the best tasting protein powder I have ever had. It mixes very well and is very smooth to drink. It is seriously difficult to not want to chug multiple servings of it like its chocolate milk

  182. Alberto V.

    Like. Flavor overall it was all good

  183. Random H.

    Quality Product
    Isoflex is great. Taking 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. The taste is superior in the chocolate flavor. Not chalky and doesn’t foam up when mixing as others do. I will continue to buy Isoflex.

  184. Erika

    Good amount for a good price.
    Love this Product not too sweet just right!

  185. M. F.

    Good price for good product- no sugar added

  186. AmberJo

    Can’t go wrong, love this product
    Absolutely love this, have bought numerous times off Amazon, great price and always receive next day! Received a day earlier than ETA given. Love

  187. Cbhappy

    Easy to mix and digest with many flavor options
    Great protein powder bcz it dissolves readily in a small volume of water. Of course it can have fruit or veg added, or be mixed with milk. No trouble digesting.
    I mix a TBL into 1-2 TBL if part- skim ricotta and spread that on toast. Tastes like Italian style cheese cake to me. It’s ok in yogurt too

  188. Bryan H.

    This is seriously the best tasting protein we have ever ordered.

  189. Edward

    Taste good!
    I order it multiple times through the same party here. Timely delivery, good product and taste. My reliable source of protein whey!

  192. Eric

    Favorite protein, wish they carried it in stores
    There are better flavors out there but this is one of my favorite proteins in general. The protein content is higher than some of the other brands out there.

  193. Cynabar

    This is by far the best protein powder I have ever tried. No chalky aftertaste. Low carb. I will definitely be ordering more.

  208. Casey

  220. Amazon C.

    Banana banana banana!
    Not many reviews for banana, but it’s unbelievably delicious!! Must be a new flavor. So smooth. It even froths like a beer!

    Few years ago I tried the chocolate chip mint, and it wasn’t nearly as good. I like smooth, not chips of chocolate in my shake.

  221. AmberJo

    Great Value, Amazing Flavor
    My favorite protein, so glad I found it on here at a great rate.

    Horrible flavor clean protein
    Flavor is absolutely horrible. Reminds me of the protein powder from the 90’s. Chalk.

  226. Jessica

    Great tasting protein!
    The taste is awesome. I’ve tired multiple chocolate flavored protein powders but this one is by far the best. I would highly recommend this protein. Its definitely worth the money.

    So tasty, add to coffee for a treat
    I was looking for a protein supplement that I could add to oat milk or coffee for a post workout treat. Even with the best planning, it is difficult to get as much protein as recommended for my health situation. This is going to help and so tasty! Blends very smoothly and no grit.
