What is Pure Whey Isolate™ 90?

Pure Whey Isolate™ 90 is the best value whey protein isolate in Europe – you won't find a WPI of comparable quality anywhere else at this low price. Essentially, Pure Whey Isolate™ 90 is an extremely high quality whey protein isolate powder, providing a huge 27g of high quality whey protein per 30g serving (based on unflavoured). In addition, Pure Whey Isolate™ 90 is derived from grass fed cow's milk, has been instantised for ease of mixing and is available in a great range of fantastic tasting flavours. See the reviews for yourself!

If you're looking at strictly controlling calorie intake and want only the highest quality protein available, then Pure Whey Isolate™ 90 is the product for you; it has less than 1g of fat and carbohydrate per serving – combined!

For added reassurance, Pure Whey Isolate™ 90 has been randomly drug screened at a renowned anti-doping laboratory.

What are the benefits of using Pure Whey Isolate™ 90?

BULK POWDERS™ Pure Whey Isolate™ 90 is manufactured using an advanced combination of ultra and micro-filtration processes, ensuring no protein denaturing and maximum protein integrity. These processes produce a pure, quality whey protein, rich in glycomacropeptides (GMP) and bio-active peptides (important for improved gut and immune function), whilst ensuring that fat, lactose and other unwanted ingredients are 'isolated' out.

Pure Whey Isolate™ 90 is then sprayed with fine lecithin particles creating a water-resistant effect on the surface of the whey protein particles, meaning no clumping… just easy mixing! The isolation processes used to produce Pure Whey Isolate™ 90 involves only natural ingredients, providing a very high quality product with an excellent protein digestability rating of 99.7%!

An instantised whey protein isolate, such as Pure Whey Isolate™ 90, has significant advantages over other proteins, the first being absorbability. Most weight trainers and athletes require a very high protein diet to aid recovery and promote growth. To break down protein sources and achieve this growth/recovery the body has to use digestive enzymes, however these are limited in quantity. So when these enzymes run out, the body loses its ability to digest these protein sources. BULK POWDERS™ Pure Whey Isolate™ 90 is composed mainly of short chain proteins and amino acids; digestion is therefore much simpler and faster than with other protein sources, allowing the protein quicker access to muscle tissue – aiding your growth and recovery!

In addition, Pure Whey Isolate™ 90 is derived from grass-fed cow’s milk which is free from hormones, antibiotics and genetic modification. Whey Protein derived from cow’s milk is said to yield a higher content of BCAA’s, boosting the overall nutritional content of the product.

How does Pure Whey Isolate™ 90 differ to Pure Whey Protein™?

As you might have inferred from the name, Pure Whey Isolate™ 90 contains 90% or more protein and very little (if any) fat and lactose. In comparison Pure Whey Protein™ contains 82% protein depending upon the product. As the protein level in whey protein concentrate decreases, the amount of fat and/or lactose usually increases! 

As an aside, BULK POWDERS™ Pure Whey Protein™ is actually a very high quality whey protein concentrate; this is obvious from its 82% protein levels. However Whey Protein Concentrate's can contain between 30% and 82% protein – so always be sure to read the label!

Suitable For



Milk & Soya (from Soya Lecithin).


Mix 1 scoop (approximately 30g) Pure Whey Isolate™ 90 with 200ml water.

Use between 1-5 servings daily depending on your protein intake requirements.

For muscle growth you should look to consume at least 2g of protein per kg of bodyweight. So if you weigh 80kg then you need a minimum of 160g protein per day for optimal muscle growth.

Pure Whey Isolate™ 90 is very fast-absorbing, so the optimal times to use it are immediately upon waking before breakfast, and immediately after exercise. After training, many athletes take a double serving (60g) as the body is able to process a larger amount of protein in its depleted state.


After exercise or training it is recommended that you combine Pure Whey Isolate™ 90 with a fast-acting carbohydrate source. Options include VitargoWaxy Maize Starch, or Dextrose. These carbohydrates create an 'insulin spike' which ensures that the protein is transported to the muscle cells in record speed. The sooner muscle cells receive this protein, the sooner they can begin to repair and grow.

In addition, Pure Whey Isolate™ 90 is extremely versatile, so it can be used in conjunction with practically any type of supplement, from Creatine to Fish Oils.

Customer Reviews

Great protein powder - chocolate peanut a bit yuk tho!!
I went over to this powder from maximuscle/maxinutrition. Firstly the powder is far better value for money.
I use this with the creatine monohydrate powder and it gives such good value.
The results are visible and it helps keep the fat off compared to some of the other powders.
I have found the chocolate peanut flavour a bit too much but vanilla and chocolate were great. Just ordered the unflavoured. On 04/11/2014 Alex said...
I really like this product!

I have ordered this product again, and after trying so many different brands this one has finally caught my attention. it very easy on the stomach, cookies, strawberry and peanut chocolate are awesome, gonna try some of the other flavors. And great on price too! recommend ! On 24/10/2014 Parvezahmed said...
Tastes like water with sugar
The only problem with this protein powder is that it very watery if you mix it with the recommended amount of water and won't dissolve easily if you mix it with any less.

Also it's a lot sweeter than it should be but this is a matter of personal preference i guess. I honestly don't know how to rate it but I am also not going to buy it again. I'll just stick to Whey protein and be fine with it.

I tried the Vanilla taste and have another 5kgs of Chocolate. Hopefully, it's going to taste better. On 09/10/2014 Charidimos said...
By far the highest quality on the market. Use as my staple supplement now. Mixes well. Tastes amazing. Affordable . No need to look else were. On 28/09/2014 David said...
Love it
I've always used other brands for my whey isolate which always cost more expensive. Then I came across this gem, and looked no further. The taste is great and the nutrition is spot on. I will not look anywhere else for my isolate anymore. 5KG does me just fine. Happy Customer!! Chocolate Cookies is very nice!! On 23/09/2014 Gaz said...
Great protein which mixes well...Chocolate Cookies is moorish. Well done Bulk Powders i will definitely be ordering more! On 15/08/2014 Russ said...
Great for lactose intolerant!
I switched to this brand of protein after using another brand that would cause myself to have an upset stomach and bloating. Since using this product I have not experienced either of these and I'm getting more protein for my money due to it's high quality! Definitely recommend to friends, flavours - you can't go wrong with Chocolate Cookies! On 06/08/2014 Owen said...
Chocolate Cookies is great!
Chocolate Cookies is delicious and vanilla is a great, simple powder that mixes well especially with frozen banana. Chocolate Peanut has a powdery taste and is disappointing - not like the Snickers flavour protein powder, I envisaged. On 05/08/2014 LA said...
Best tasting shake i have had, have it with milk!

As yet to try it hot as per another review, but will get round to it! On 01/08/2014 Chris said...
I am just about to finish my first bag, incredible product. Helps my growing girl muscles recover and fills me up nicely post workout.

I can say that this product does not make me bloat, HURRAY! Finally found a product that makes me feel amazing, great value for money, awesome quality too.

Going to keep on buying and i recommend everyone to give it a go and see these great results for themselves On 28/07/2014 Stephanie said...
Great Product
Been using Maximuscle (and the new Maxinutrition) for a while as I was getting it quite cheap on Amazon however when I came across this range with the protein content and the price I had to give it a try and will not look back - excellent product. On 07/07/2014 Mike said...
I just finished my unflavored isolate.

If you don't need a fancy taste, this one is a great choice.
On 06/06/2014 Galle said...
Really Impressed
I really like this product it mixes well and doesn't bloat me like most protein supplements. As a bonus it doesnt taste half bad. It got to me relatively quickly after placing my order would defonately recommend it. On 04/06/2014 Aaron said...
Can't recommend this product enough... excellent, great value!! On 26/05/2014 Jonnussss said...
Chocolate Peanut
Nice flavor.....product works nice mixing is also very good......... On 08/05/2014 adeel said...
Gives me wind but its still good!
I'm one of those people who have trouble digesting lactose, so I opted for this hoping it wouldn't give me any tummy troubles... Six hours later and my bottom was singing like a whale. Roll forward a week and after a purchasing and taking a lactase enzyme supplement before I drink it, it's all good, no gas and no bloating! I've only had the cookies flavour and it mixes up well in water and helps me recover. I'm not interested in building muscle mass I just want to keep what I have and recover quickly - this is perfect, no DOMS and plenty of energy post workout. On 04/05/2014 Dudey said...
Isolate 90 (Toffee Popcorn and Chocolate Peanut)
Great protein, bought both Chocolate Peanut and Toffee Popcorn flavours. The chocolate Peanut wasn't too my taste as it was a bit too sweet. But the Toffee Popcorn was spot on! Great product. On 30/04/2014 J.Y said...
Very good
Tastes great, mixes easily, works well. Overall a very good product. On 29/04/2014 Sam said...
What a great product. Mixes well and tastes great. Started with Banana which to me seemed to have a slight chemical after taste. After a couple of shakes this was not noticed.

Next tried Choc-Peanut. Fantastic. Got to be the best tasting protein I have tried so far.

Ideal protein levels. Results noticed after short time. Will be ordering more. On 24/04/2014 Brian said...
chocolate cookies
I have tried many different flavours from various different brands, big and small and the Bulk Powders Chocolate Cookies flavour has got to be one of the best I have had! On 21/03/2014 Luke said...
Chocolate Cookies flavour
I am using this for health reasons so can't tell you what it may do for workout recovery etc, but all I can say is that the taste is really good - it doesn't taste like a nutritional supplement at all, so far I've only mixed with water but will be trying it with milk as I imagine that will be amazing. The price is also great and the protein levels are just what I need (recommended by physician for twin pregnancy) - thank you =) On 07/03/2014 Kirsty said...
Easy mix great product
I bought this, it mixes easy and tastes ok, that is the choc peanut flavour although just not to my taste. The strawberry one is great I would recommend it! On 16/02/2014 Parm said...
chocolate cookies and chocolate taste
Can see results already after a few months. The taste is fantastic. Chocolate is what you'd expect... tastes like chocolate so if you like that and don't wanna risk go for it you got nothing to lose.

Now the Chocolate Cookie taste really surprised me! It doesn't taste like chocolate it taste as if you dipped a cookie into hot milk and ate it. I couldn't believe it! It literally tastes like eating that cookie soaked in milk. Phenomenal if you drink it warm/hot! On 06/02/2014 Gasper said...
Great product
Nice lean, pure product with a Great taste. Next to no clumping as well which is preferable. On 04/02/2014 Ewan said...
Another top quality prouduct
Only started taking this so results aren't noticeable yet.. But for price and taste this is better than anything I've tried before and has a higher protein content per scoop (slightly less than the unflavoured one though). Be nice to know the amino acid profile too though. On 29/01/2014 Dave S said...
Great Product!
Banana tastes great, easy to mix in the Bulk Powders shaker, one of the best I've tried!

Results seem to be showing it works too! On 21/01/2014 TOM said...
Love Chocolate Peanut
Super fast delivery and wow the taste is amazing, I had the chocolate peanut and it actually remind me of Reeses peanut butter cup. it can be a bit sweet but just add plenty of water, after taste isn't too bad either. Can't wait to try in milk. Best thing is it's 27g of protein per 30g scoop so you can't go wrong. On 30/12/2013 Kay said...
Great mixing, taste is fine with water but the quality of the product is outstanding. Feeds my muscles in the morning and post workout, excellent recovery from this stuff. Ordered more, highly recommended! On 27/11/2013 Arron said...
For post-workout...
This whey isolate the best ISO that I have used so far. I am not only talking about its taste and feature of mixing well, but also it regenerates the body perfectly just after tough training. Good quality product! 100% suggested! On 24/11/2013 C@N said...
Awesome protein, 27g of protein for a 30g scoop is amazing and exactly what I was looking for. The price as well is not to be sniffed at. I mix this with BP's ultra fine oats and have seen noticeable results. Coupled with some BCAA a few times a day and have noticed big differences in my strength in such a short space of time.

Tried the vanilla one also - amazing!

Can't believe something this good for you tastes this good.

Definite 5 stars and a customer for life! Well done BULK POWDERS! On 19/11/2013 Gasper said...
Great taste - Easy mix
Chocolate flavour tastes great and mixes excellently with water. No frothiness at all. Have not tried with milk. On 16/11/2013 Boycey said...
Premium quality protein
Such a good quality protein powder with one of the best nutritional profiles I've come across. Pure whey protein isolate without all of the added unheard of and artificial ingredients other companies add. I last ordered the chocolate cookies and although I wasn't a fan of the flavour (it was too sweet for me) I am definitely ordering some more of another flavour.

Has anyone tried the strawberry flavour? I would love to know if it's good or not? Otherwise vanilla never fails!

It would be even better if Bulk Powders sweetened their protein with stevia instead of sucralose, but other than that I can't fault it. On 12/11/2013 Lucy said...
Simply Great
Great protein product, affordable and effective. On 11/11/2013 Andreas said...
Wow, I had to review this ... I have tried my fair share of products with only BSN Syntha 6 coming close flavour-wise but the chocolate peanut flavour is by far the best tasting whey ive ever tried.

It's also got 27g of protein per 30g and is the cheapest I can find, this is amazing, mixed with coconut milk it becomes lush and tastes like Snickers !!!!! On 06/11/2013 marc said...
Best ever tasting Protein
BP is excellent in everything! I ordered Chocolate Peanut butter flavour. This is one of the best tasting proteins I have ever tasted. It has just 0.6g carbs per serving but tastes awesome. Definitely will order this protein again and again. Please BP don't discontinue this taste or don't say out of stock. :)

The only one thing I don't like about BP, they never provide scoop with protein. Spending £40 for 2.5kg whey and don't get a scoop is bit disappointing to me. But still I gave 5* and hopefully they will consider On 31/10/2013 Harry said...
Whey Protein Isolate 90
This product works and tastes excellent, very much like a milkshake. I've tried banana and strawberry. Best of all it mixes so easy, just put in a glass and stir with spoon, all done! Ordering Whey 97 next and will let you know what that's like. PS.6 teaspoons or 3 tablespoons is 30g, which you will need approx 6 times a day and is approx. 162g protein per day plus, topped up with protein from foods such as eggs, chicken etc. This will do if you are trying to build muscle and are 190 to 200lbs weight, Thought this might help but just ignore if you have got your own method! On 17/10/2013 jav said...
Tastes great as good if not better than the (more expensive) leading brands.
I bought 5 kilos of the Chocolate Cookies and have to say, the flavour is amazing! I mix it at work into my oats and everyone always comments how good it smells (like buttery chocolate) and have to say the taste does not disappoint - now glad I bought the 'BIG' bag as I look forward to a quick fix of it when I need it. It mixes very well for cooking with too, I often make protein pancakes with it and have made protein bars too. Will certainly be back for more! On 10/09/2013 Simon said...
Taste doesn't get sickly at all, mixes really well and great nutritional values at a good price. On 05/09/2013 Luke said...
Chocolate cookies
The Chocolate Cookies flavour is amazing. Another reason to workout so I get to drink this though I'm a little disappointed after I finish it cause it's so tasty. Originally was looking for Hydrolysed Whey but as Bulk Powders don't sell that this is the next best thing. On 02/09/2013 Richard said...
Great value product.
I've tried many different brands of protein but this one is my favourite. Great flavour (banana), and good stats on the nutritional values. It's also one of the best value basic formulas out there. If you want a powder that doesn't have all the added creatine/glutamine/bull testicles then I highly recommend that you try this. The only issue is that it doesn't mix brilliantly with milk, but Bulk Powders suggest doing it with water, so in no way is that a complaint! And I've actually found that mixing with half water and half milk gives perfect blend and makes it taste even better! On 19/08/2013 Luke said...
Great protein
Great Protein Isolate! On 02/08/2013 Viktoriya said...
Great Product
Been taking this for a while now around 2 years. Great product everything you need without the added rubbish other Whey Protein supplements add, and for the price an Absolute Bargain! On 25/07/2013 Jordan said...
Quality and great tasting product, what more can you ask for?
Just bought 1kg of the chocolate cookies and I am now addicted to the taste! Bought it to go along side my unflavored as a tasty alternative but find I'm drinking more of the cookies it's that good! Mixes really well too, I'll definitely be repurchasing! Thanks! On 18/07/2013 Alison said...
Clearer directions are needed
I've only just started using this so I haven't see the full benefits of it yet. Nutrition wise it is exactly what I'm looking for. I've only tried the Chocolate flavour which is quite nice. I'll try the Cookie flavour next as I've had another product in this flavour and I liked it.

I would like to know what the optimum water to powder ratio is. The directions give no indication as to the amount of water needed for 30g so at the moment I'm in a trial and error stage. I can't remember if there is any directions on the packaging (I'm not with that right now so can't check) but I was hoping to find some directions on here.

Either way, great tasting product On 01/07/2013 Corin said...
Blows every protein out of the water
This taste, price and quality blows everything else out of the water, the protein has a better quality than ON protein and is more less costly. I tried 3 flavours, strawberry (not bad), Chocolate (very very good) and chocolate cookies, WHICH IS AMAZING, when i made myself a shake my niece smelled the chocolate and was running in asking for a taste ! Kids know what is good. Every time I look for a protein online I always come back to BULK POWDERS! On 15/06/2013 Maciej said...
Chocolate Cookies
Brilliant taste. Smells like cookies or cakes haha. Second time buying BULK POWDERS whey. Strawberry was okay but I've had better. Mixes well = good quality whey. Your welcome for the review haha, althouhg wouldn't mind some bonus for this review :D

Definitely getting more from them after I'm done. I would love to try all the flavours before choosing one though, which would make it easier to make my mind up on which flavour to stick with. Maybe some cheap samples or samples when orders are made over £50 or something? On 31/05/2013 Kar Kin said...
Great tasting, quality protein
The one slight downside of this protein in my optinion was having to learn how best to mix - it's not quite as forgiving as the 82%, but as long as I add the powder to the water, it mixes just fine.

This is the best tasting unflavoured protein I've come across, and I barely notice I've drunk anything after gulping down a shakerful.

I'm not a heavy user, but I have noticed that this really boosts my muscles post-workout and raises the bar relative to the 82%. On 30/05/2013 Matt said...
I bought the Banana 2.5kg version, everything is 5 stars. It tastes so good, and is very good at mixing with water/milk. On 29/05/2013 Ben said...
It really works
At first I was pessimistic but when I tried out this tasteless protein isolate, I was starting to gain more muscle than I was before while using branded proteins. On 11/04/2013 Donatas said...
The Mr T of protein
I'm currently a personal trainer and have used whey protein as a cooking medium and post work out supplement for as long as I can remember, using brands such as maximuscle, reflex and many others but never have I been happier.

I use it with oats in the morning along with pre and post work out and in the last 9 months seen the best strength and size gains in both myself and clients to who I have recommended it to.

if your thinking about trying it, JUST DO IT, I can tell you know you will never turn back. On 09/01/2013 chris cooney said...
Great, great product! Mixes perfectly!

The taste (chocolate cookies) is just delicious! I could eat it raw with a table spoon.

When it comes to results, it's awesome! I've seen very good gains in lean muscle mass with it. Your diet and training MUST follow of course. On 01/01/2013 Dani said...
Great protein, great price
Amazing clean protein product, I've got unflavoured and cookies and cream. I mix them half and half and it still tastes great. There is no point spending loads on products from rip off companies this is premium stuff. No stomach issues with this product at all. Will buy again for sure. On 07/10/2012 Vik said...
tastes ok to me. digests really well. I don't even know i have had it - does not fill me up, cause bloating or gas. Perfect On 15/09/2012 Lee said...
Absolutely Awesome
Just received this the chocolate & chocolate cookies in 500g pouches i wanted to try both flavours as a trial as it is my first time using bulk powders i never really liked the flavours from my old protein that i used to use and the quality of the whey isolate beats anything in its league, awesome service i will be using no one else but bulk powders from now on! thanks bp On 25/08/2012 Arron said...
DIY Weight gain
Have started using this protein in combination with maltodextrin and dexrose (also from bulk powders) I ordered 500g of Chocolate Cookies and 500g Strawberry. I enjoy having the ability to pre determine my intake by choosing how much protein and whether to use fast or slow releasing carbs mixed in depending on pre/post workout or before bed and first thing. Its allowed me to think about my actual requirements rather than just taking a scoop from my normal bright coloured, over marketed products. Both flavours mix well with milk and water with no powder clumps (which was not the case with my previous Phd stack). All in all a great buy and no doubt!

Cheers BP On 21/08/2012 Bez said...
Unflavoured whey isolate
Mixes well in shaker bottle and is probably the best tasting unflavoured isolate I have tried. I have almost finished my previous 5Kg order and will definately re order. On 19/08/2012 Steve C said...
Very Happy
Quick delivery.

I got the unflavoured one. Mixes well but goes quite bubbly and frothy on the top. It settles after a while though.
I mix it with water and squash. Tastes a bit creamy but its not bad tasting at all.

And a 90% isolate for this price is unreal. 5 stars. On 10/08/2012 Callum said...
looks good
looks good but quite expensive in my opinion.
On 04/07/2012 fresh said...
I love this protein, Unflavored taste like crap but it does the job of building muscle just like the big name brands (As it should).

Highly recommended! On 30/05/2012 Anonymous said...
Great tasting, great mixing :)
New to this lark.... I bought the 90% due to comments about the 97% not mixing so well.
I'm glad I did, the 90% mixes so well, especially using the blender bottle; which I also bought.
I have only tried the strawberry and I think it tastes great!

So good that I'm back on the site today to buy more :) On 28/05/2012 JT said...
