Ive lost a dress size and i actually have definition ......never too late to shape up. Loving it

  4. Great value and quality

    Verified Buyer posted

    This is a great quality protein powder. Has a high protein content, plus a good amino acid profile to ensure maximum results from you workout. I like to add my own flavours to the natural powder, such as peanut butter, chocolate or honey, so the flavour never gets boring. The quality seal on the pack helps keep the product fresh for ages and shipping , as always was fast and easy. Great product.

  5. UProtein's RAW Isolate Whey Protein Makes me Feel Great!

    Verified Buyer posted

    UProtein's protein range is as good as it gets. I found these guys by thorough research and am glad I did! UProtein is an Australian owned company and provides protein and supplements to suit all lifestyles. I'm a long-time customer now and really enjoy their RAW range. No nasties nor preservatives, which makes me feel great post-workout.

  6. Nice pure whey iso.

    Verified Buyer posted

    Best raw pure iso protein. With the highest protein per serving. My stomach feel full everytime and it doesn't crumble when i take it. I would recommend this to all my lifters friend!!

  7. I've been converted.

    Verified Buyer posted

    I've bought my protein in bulk for the last ten years and have tried more suppliers than I can count.
    In my experience there are three factors to any protein purchase- quality, quantity and price. Generally speaking, you can pick a product with only two of those three things.

    I got used to buying products that sacrificed quality for a cheaper bottom line: beggars can't be choosers. Most powders on the market at a reasonable price point are blends, or mix poorly, or taste terrible.

    Not anymore.

    I took a chance on uProtein and haven't regretted it. It's simple- quality, hydrolysed protein which is more bioavailable than regular WPI, that mixes well and tastes great for a bargain price. I'm paying less per kilo for a better quality product than I was from the other major players.

    If you lift, you need protein. If you need protein, then you need uProtein.

    I couldn't be happier. Highly recommended.

    Verified Buyer posted

    best pure protein at a great price!
    Im off today to do 7 marathons in 7 states in 7 days for kids charity Bravehearts.I run a lot of marathons and a lot of that is because this product helps recovery and rebuilding of muscle.Really recommend this protein

  9. Easily digestible, great for health, not just muscle building

    Verified Buyer posted

    I had a period of being unwell and was quite deconditioned, so wanted to add extra protein to my diet to rebuild. I had previously tried only one protein drink from the pharmacy, which was gross.
    This product is easy to digest, which is important because sometimes I have had digestion issues with eating meat. I love that it has a high protein content and doesn't contain all the additives like sugars & artificial flavouring. I have given it 4 stars because it doesn't mix as easily as what it claims, and at full price is not cheap, but I am otherwise very happy with the product.

  10. The Best Protein I have used

    Verified Buyer posted

    Having used a lot of protein over the years I was super impressed by the quality of the Natural Whey Protein Isolate +XHL. Great price for 37 grams of Protein low carbs and fat .
    If there is a better product I have not seen it. Totally my benchmark in a Protein powder

  11. Great value!!!

    Verified Buyer posted

    Exceptional value for this unbelievable product! Mixes very easy. It is unflavoured, so you may need to add a little something extra however I don’t mind the taste?

  12. Amazing and Natural

    Verified Buyer posted

    Uprotein's Raw Whey Isolate is an absolute must for anyone he cares about what ingredients and nutrients you are fuelling your body with.
    It works well in any shake and tastes better than any other whey proteins I've had.

  13. Thankful

    Verified Buyer posted

Since I am taking UProtein I feel already into the next level of training never reached before..

  14. Raw range natural whey protein isolate.

    Verified Buyer posted

    I’ve been hitting the gym for 30 plus years and have used many other WPI protein powders. I’m really impressed with the quality, price and service, happy customer.

  15. It works

    Verified Buyer posted

    Just finished a chocolate flavoured mix from a different company, this even though flavourless is definitely the real thing. Fast delivery as well, will be back for more.

  16. Raw range

    Verified Buyer posted

    The search is over.
    This protein powder ticks all the boxes, so.much so I have just bought my second batch of the 4kg pack.
    Its all natural, there are no numbers or words you don't know on the ingredient list, so you know what is going in your body.
    It mixes great.
    It doesn't upset my stomach, leaving me gassy and bloated like other whey protein powders I have used in the past.
    Its great value for money.
    And Uprotein's same day dispatch means I'm not waiting very long for my package to arrive.
    Thanks guys, your pure protein has helped me stack on muscle and is helping me reach my goals in the gym, from a very satisfied client

  17. Great product recommend

    Verified Buyer posted

    Very happy with this protein, both Vanilla Custard and Choc Brownie taste great and mix well. Also really good to find a quality protein that's very low in sugar. Highly Reccomend

  18. Worth giving it a go

    Verified Buyer posted

    I have been in the fitness industry for over 30 years over that time I have used and tried a few different protein powders and always do a lot of research before I commit to buying. In saying that I have found UProtein's Whey Isolate to be what it states a clean natural protein. I blend it with water and a frozen over ripe banana it taste great and I will be sticking with it and recommending that same. Well done guys. Its work giving it a go.

  19. 100 % Natural

    Verified Buyer posted

    UProtein's Whey Isolate RAW range is fantastic! I wanted to wait to try this product before I rated it ... and I'm glad I did! Anyone who takes an interest in additives, preservatives and the like in food, will be pleased that this item has none of that! Completely clean, it will refuel your body, restoring it to the temple it should be. The taste is different to normal Whey Isolate, however this comes down to personal prefernece ... which I enjoy! Great job once again UProtein!

  20. Such a Wonderful Product!

    Verified Buyer posted

    We are absolutely amazed and happy with the product. We used after a workout and also in some culinary preparations as Sugar-free cakes and smoothies. As is unsweetened, is easy to mix with fruits, however, if you drink it alone taste good as well. The content is perfect and compared with other proteins that we had been used before, this one is beyond any other. We are very happy with this purchase! Truly encourage people to buy this product!

No Cheap WPC

We don't use outdated refinement and production methods.
Sure, these methods are cheaper but often they result in less protein nutrients per serve, along with inferior taste and biological benefits.
If your muscles could talk, they'd say no to cheap WPC too.

Clinically Proven Natural Whey Protein Isolate

The way a protein is hydrolysed is supremely important, thats why we only use the Enzymatically Hydrolysed Treatment (EHT) process.
This ensures more amino structures are available, ensuring optimal nutrient uptake and true muscle results.



As one of the largest sports nutrition manufacturers in Australia, we cant rely on just one local supplier,
that's why we look locally and globally for suppliers who have the scale and techology we demand.
Our whey ingredients come from high quality cows that pasture in AUS, USA, and NZ farms.
