Our Hydrolysed Casein is a fast acting protein made in NZ, for athletes whose goal is to gain lean muscle mass and/or increase recovery times.

With a low average molecular weight of 2930 Daltons and its high level of short chain peptides it is absorbed by the body rapidly, enabling a quick increase in protein synthesis making it ideal to consume pre, intra and post workout.

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

  • Low Average Molecular Weight of 2930 Daltons
  • Moderate Degree of Hydrolysis at 10%
  • Very High Levels of Low Molecular Weight Peptides
  • Over 95% Protein (dry basis), Almost Zero Fat and Carbs

This makes it significantly superior to WPC, WPI, regular Casein and 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 synergistic benefits of whey peptides and casein peptides.

Note: Hydrolysed Casein has a 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.

Though this proteins flavour can take s bit to get used to it's well worth it. I really enjoy it now. Mixes super easy.

Great recovery!

By: on 15 September 2016
This is a great protein to help speed up recovery from intense/heavy weight sessions.I add 10g to my preworkout mix followed buy a 50g mix post workout of hydrolysed casein and HWPI 50/50 ratio. Works extremely well. One tip when mixing is to stir, do not shake, it will get to frothy. Highly recommend when heavy sessions are on the card.

Great, and flavour is ok too

I mix this 50:50 with WPC and some "greens" powder and don't find the taste a problem at all. Haven't been using it long enough to know conclusively if it makes a difference but I have finally started putting on a bit of size and weight so maybe it is. And really, if anyone thinks this tastes bad, they really need to harden up :)

Best value pure and Natural Hydrolysed Casein

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 Hydrolysed Casein products. 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. For additional benefits I also mix bovine colostrum.

Pleased with the results!

Yes, it’s true – this product doesn’t taste the best and it doesn’t mix all that well. But it does seem to give the results. Progression diminishes after the first couple of years of training. I’ve trained for a solid 7 years and tried many whey products and although I’ve been hitting it hard I hadn’t seemed to add much to the scale in the past year. Switching to Hydro Casein has gotten me out of my plateau and significantly reduced DOMS. I mix with dextrose and half a serving of WPC, continuously shaking seems to eventually mix the product.

Harden up Princess!

Read that the H. Casein is hard to swallow. Yep, how true! I would like to suggest that Professional Whey provide a sample pack. Due to the fact that I am not going to waste my recent purchase, I found the best way to consume it, is to mix it in a glass of water until it is semi lumpy and chow it down as fast as I can. Make sure you are standing over the kitchen sink in case the gag reflex kicks in...Burp!

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

Excellent protein

By: on 2 January 2015
If you can get past the taste, this is a great post workout protein. I've noticed a difference with my recovery times and the results are showing.

Great Protein! Fast Delivery

By: on 29 April 2014
I found this protein to be well worth the money! Ive usually been using it in conjunction with a blender, but i still found it was ok to mix in with a shaker bottle. The taste initially was pretty bad but not really noticing it now. Well worth it and noticing the results!

You will never get over the taste but it's good. Don't spill it on your kitchen bench and let it dry. You won't get it off. If you have run out of gyprock for home improvements, this works a treat on a 50/50 water mix. In regards to training, well worth the investment. Try it for yourself and you will notice better recovery. Only for the hardcore if I had to be honest and if that's you, go for it.

Amazing quality

By: on 7 July 2013
I usually buy a selection of proteins from Professional Whey to mix my own combinations. Hydrolysed Casein is always in the intra and post shakes. Gets to work fast! In fact I have purchased this product a few times now. Won't stop :)

Good pre/post protein

By: on 2 July 2013
I have been giving Hydrolysed Casein a try after using Pepto Pro. I use it 50/50 with hydrolysed whey as part of the ultimate pre/post workout formula. I mix it with a stick blender a don't have any real mixability issues. It is very bitter but is easily masked with stevia, cacao etc. I seems to help well with recovery and lean muscle gains when doing P90x programs. At this point I will keep on using it.

Tastes well enough

By: on 23 June 2013
It mixes well enough. Mix it in a shaker at the beginning of a workout session and by the end it will dissolve (shake it a couple of times in between sets). The taste of this version is less bitter than others I have had. The taste is not disgusting, just bitter. I add about 5g of glucose to this, around 1/4 standard teaspoon of salt and a small serve of creatine monohydrate. The taste is perfectly fine in this combination. Results are hard to measure for everyone, so judge for yourself.

Product review update

By: on 30 December 2012
I've now been using this for three months and love it. I'm now used to the taste and use this with the hydrolised isolate. My primary reason for purchase was to assist with recovery. In the past 3m. I continue to hit more PB's than over the past 6m period. I can say it has helped give the appearance of more muscle mass although this has not been measured nor has it been a personal reason for purchase. Missing a * for price. A great product none the less.

super duper!

By: on 4 November 2012
doesnt mix well and tastes like ass. but we dont use hydro casein for its delicious taste. we use it for its super fast absorbtion and enhanced insulin responce. and its way cheeper than peptopro.

Doesn't mix well

By: on 20 September 2012
Ditto to the comment. The only way I've been able to remove the lumps is with a blender. It will not mix well with a conventional protein shaker. Can't yet vouch for the quality of the protein. As the description of the product states it does have a bitter taste although easily masked with some raw cacao or cinnamon.

Poor mixerbility

By: on 12 June 2012
Does not mix well. Did not like the taste. Couldn't tell the difference between a good WPI and this Hydrolysed Casein.
