Super quick delivery and the protein dissolves very nicely so it’s not lumpy, super happy with this product.
5/5
I have so so many protein containers at home virtually untouched because I hate the protein taste. This one I can actually drink and look forward to having everyday. It tastes like the left over milk after cocopops with no yucky proteinish taste lingering. Good price for the quality of the protein. Absolutely recommend this flavour to anyone!

4/5
Delicious! Mixes well and super easy to drink
5/5
Most likely absolutely defiantly the best flavour, mixes so well as a smoothie or on its own, have had other brands and mixes and they don’t mix half as well as this brand and flavour !
5/5
Great taste! Love this, no yucky after taste.

Awesome
5/5
Have purchased this protein powder many a times and for a good reason. It's scrummy!
5/5
Great deals, product availability
5/5
I find this Whey powder to be of the highest quality (and best tasting), that I’ve tried so far. It mixes really well, which surprised me a lot considering the previous powder I used took about a minute to, and even then still left clumps at the bottom of my shaker. Having BCAAS in the powder was also something I found perfect for muscle recovery, and it’s efficient in getting those amino acids in without the need to purchase BCAAS on their own. Definitely continuing to get this Whey powder.
5/5

Best protein, have tried others but prefer this brand and Choclate flavour. Always tastes great. Outstanding service and often receive products within 2days of placing order. Great considering I am rural. 100% Happy customer.

Absolutely loved this. The taste was amazing as I knew it would be and is very versatile when incorporating into meals.
4.5/5
The Mocha Cappuccino flavour is SO delicious, especially with milk and I was so stoked with how quickly it arrived (even during lockdown). A bit thin with water alone but great for low carb macros
5/5
Love this flavour. Taste nice in everything
4.5/5
The vanilla ice cream is the best protein I've had in my life. I've always chosen chocolate as a 'safe' option, but decided to try vanilla this time. It goes with almost everything, great in smoothies and oats for sure
5/5
SUCH A GOOD PROTEIN POWDER! I’ve gone through a few protein powders and this is by far my favourite so far, very excited to try the other flavours!
5/5
Another lockdown, another time I forgot to grab protein before everything closed. A lot of sites say they are able to ship, but then have disclaimers. These guys shipped during level 4 lockdown and did it super-fast to boot. Highly recommend, no fuss, well packaged and good price
4/5
Nothing new to say here as I always go for On 100% whey protein. The brand is well known, so not much to say about quality. This time I ordered French vanilla flavor. It's a pretty decent flavor, but I would prefer double chocolate favor more, which I buy most of the time. Shipping and delivery was prompt.
5/5
Great product. Extreme milk chocolate flavor is delicious.
5/5

4/5
Always a trusted brand. Best with milk
5/5
Awesome all round protein, great flavours.
3.5/5
Is okay. EHPlabs chocolate is probably better but this is still fine. Mix with unsweetened vanilla almons milk and add sweetener and you’ll be on your way

Mocha cappuccino smells very bad and taste yucky in water, taste is also not like a coffee big no no avoid

not the best tasting protein powder but has a good amount of protein per serving so there’s pros and cons

The fact it’s the world number one sold whey protein powder by volume speaks for itself. I take two scoops during workout and two to go with diet everyday. Seeing prominent result.
