Made in NZ, our Hydrolysed WPI is one of the most advanced whey proteins to assist with gaining lean muscle and/or increasing recovery. Reason being, the proteins are broken into smaller protein chains so they are absorbed much quicker by the body.

With a degree of hydrolysis of 20.7% and a low average molecular weight of 1400 Daltons, it has very high levels of Di & Tri Peptides which assist with rapid absorption, enabling a quick increase in protein synthesis making it ideal to consume around your workout.

Professional Whey is proud to offer what we consider to be highest quality pre-digested whey protein isolate available in Australia. The facts are:

  • Low Average Molecular Weight of 1400 Daltons
  • High Degree of Hydrolysis at 20.7%
  • High Level of Di, Tri Peptides & other low molecular weight Peptides
  • Over 95% Protein (dry basis), Less than 1% Fat and Carbs

This makes it significantly superior to Whey Protein Isolate and Concentrates but there is evidence that shows Hydrolysed Casein to be a superior choice over Hydrolysed WPI when it comes to muscle gain and fat loss.

However we recommend Hydrolysed Casein and Hydrolysed WPI being used together to get the synergstic benefits of whey peptides and casein peptides.

Available in 1kg packs.

Note: Hydrolysed WPI has a very bitter taste, due to its hydrolysis. Organic Stevia Extract and Dextrose do mask most of the bitterness. Also the hydrolysis creates a very microscopic fine powder which will froth when shaken, so please gently stir if you want to avoid the frothiness.

  • Increased Protein Synthesis

Hydrolysed WPI (and Hydrolysed Casein combination)

By: on 20 August 2017
Historically, I've taken the NZ WPI or Hydrolysed WPI. More recently, I've tried a Hydrolysed WPI/Hydrolysed Casein combination. I've found that combination to cause major gastrointestinal problems. After a number of attempts, I decided to remove the Casein from the combination and my problems all but disappeared within days. I've stuck with the Hydrolysed WPI which I believe is good - as far as supplements go. Matt

Great product mixes easily.No clumping. Unflavoured has a very mildly bitter taste that is not unpleasant. No bloat or discomfort. Greatly improved recovery. Great protein absorbtion. ideal for those of us over 50s

One of the best All Natural HWPIs

By: on 18 November 2015
This product is all natural with no additives and as such is the best supplement for anyone sensitive to lecithins and numerous other additives found in most HWPIs. Additionally, it is fast acting, doesn't leave you feeling bloated and is best value for money. I find it helpful to mix this with natural Rice and Pea proteins to reduce frothiness; stavia for taste and finally Psyllium husk for fibre.

Hydrolysed WPI

I've been using this product for 3 years now, although it has a bitter taste I mix it with coconut water and Professional whey Dextrose which makes it quite pleasant. Wouldn't swap to anything else. Prompt quick Delivery too

I have used a number of protein products over the years and this is by far the best for results. The high quality fast absorbing protein has allowed for better recoveries. It has an awful bitter taste. I usually counteract this by including some flavored whey isolate. As per price, this is the cheapest, highest quality Hydolysed protein I can find. Well worth the money.

Fast Acting and Effective

By: on 4 October 2015
I tried this out and am very satisfied with the results. Good diet is one of the keys of success - plug this into your diet and you are set up for success. Add the excellent customer service of Professional Whey into the equation and you can't go wrong.

I mix this with the Hydrolysed Casein and a spoon of milo. tastes fine and gets fast results. Definitely brilliant products.


By: on 22 December 2014
Very good quality product, fast results to boot too ... the taste takes a little getting used too but then again the worse it takes the more natural it is !!!

Awesome and worth EVERY cent

By: on 29 April 2014
I found this, when used in conjunction with hydrolysed casein, to be very effective when used with an appropriate weight program. I was able to mix it ok, and found the taste, (initially quite different) to be manageable with some of their other products. I would definitely recommend this to anyone who is serious about their training. Fast acting protein, from the purest sources!! 12/10 ;)

The Protein You Need

By: on 29 March 2014
Some products might taste better, but if you want to do the best for your body you need the purest best Protein you can get. Don't put sweeteners and other junk into your body. This is the one you want. Excellent price as well and service is always the best.

Good results

By: on 16 February 2014
Good results but the taste, OMG ! is just unforgettable. I sing nursery rhymes to gather all my courage after putting it on the table, ready to drink. Jingle Bell Jingle Bell or Baa Baa Black Sheep comes out spontaneously when I stare on it. :))


By: on 3 January 2014
Very high quality product, even though it tastes quite dreadful, the benefits highly outweigh that only negative, its a small price to pay for the results it brings. Ideal for bodybuilding A++

Results, and Fast

By: on 15 November 2013
I started using the Hydrolysed WPI about 3 weeks ago and found instantly I was recovering faster. The taste isn't great, but I found I got used to that. This is a great product that is a fresh change to the overpriced protein powders found in supplement stores with a million ingredients. You know exactly what you are injesting and no concerns about artificial flavouring, etc. Tip - was shaker immediately and if left in sun for just half a day it becomes a chemical biohazard!

Actually like the taste...

By: on 13 October 2013
I KNOW, crazy. But true. I've been on this for a couple of months now, and when I first tried it I concluded that it was the most disgusting tasting thing I had ever put in my mouth. Doesn't mix well, had to combine it with copious amounts of cinnamon and stevia to mask the horror that was assaulting my taste buds. However, over time... it grew on me. And now I simply whisk it with water- no need to hold my nose anymore. So it IS POSSIBLE! I gain quicker with this product. Bring on the bulk orders!!

Doesn't have to taste disgusting!

By: on 26 September 2013
I started using this on its own (with water) and with dextrose. Either way it tasted bad! But then I tried adding stevia extact (1/8 tsp) and cacao (1/2 tsp) to just the WPI (without dexterose) - it actually tasted great! Really great! Don't torture yourself - get the stevia & cacao. Vanilla extract might be good too. Also I started trying to mix without a shaker (stiring with a fork) - okay (but lumpy) if you gradually add water to make a paste. But much better if you buy PW shaker - quick and easy mix (with very slight lumps).

brilliant, tastes like old socks, but the results

By: on 18 January 2013
I have to say ther hydrolysed protein was a more qurious purchase for me as i have never used before. They are right to say it is 'bitter', hell yes its bitter, but easy to disguise with flavouring. The results i have gotten from this though is outstanding, my recovery time is improved beyond what i expected and muscle tissue is noticeably improved. Beware though as it is a fine hydrolisysis, and it tends to create a cloud when mixing it, strongly suggest a shaker for this one

Taste Hard to Take!!!!

By: on 10 October 2012
Ben's comment is spot on! A high quality product but the taste makes me literally gag. I'm wondering if there is ANYTHING that can make it taste even a fraction palatable. I use other protein products from professional whey so I think I may have to mix.

Great product, tastes like dealth

By: on 1 August 2012
Great results from it but damn it tastes bad. Is so offensive when mixed that needs a whole tablespoon of coffee powder to make it bearable. Will keep using though....no pain no gain!

good if we stack

By: on 28 June 2012
this is good quality protein if we stack with hydro casein and other recomended stacks together I am getting very good improvment and fat loss.....taste bad but after some days it will not feel bad

Fantastic WPI, terrible taste.

By: on 24 May 2012
Obviously a very good quality WPI and hydrolised to a higher percentage than most other proteins I have encountered. Unfortunately though, unless mixed with something else the taste is unbearable! The warning of "a bitter taste" should read "taste like satans gym socks".
